&nbsp;

Greg pushed the button on the treadmill to make it speed up slightly.&nbsp; He could feel the ache starting in the right side of his stomach but he felt restless.&nbsp; Around him were people in various levels of fitness running, jogging or walking on the other treadmills.&nbsp; The gym was fairly packed for a Saturday evening but he'd been lucky enough to find an empty spot.&nbsp; Usually he skipped exercising on the weekends but he woke feeling out-of-sorts and decided to try the gym rather than pace his small apartment.

&nbsp;

An attractive lady stole a glance at him, smiling as she did.&nbsp; He smiled back but kept his breathing to the proper rhythm.&nbsp; The woman stopped on her treadmill to wipe her face and stretch in an exaggerated manner, her chest pushing out to emphasize her breasts beneath the sports bra.&nbsp; Her eyes darted to Greg again before she went through a few quick stretches.

&nbsp;

Greg sighed.&nbsp; She was part of the problem.&nbsp; Well, not her specifically.&nbsp; Women.&nbsp; He was twenty-eight years old and, as far as he knew he was straight.&nbsp; However, for the past few months Greg found himself fantasizing about men.&nbsp; One night, while he was masturbating to the thought of banging some made up woman he found himself wondering what it would feel like to be in her place.&nbsp; What would it feel like to have breasts with sensitive nipples?&nbsp; Breasts you could play with whenever you wanted.&nbsp; And a pussy... He'd seen his fair share of vaginas throughout his life and he'd always envied women with their ability to have multiple orgasms - mind blowing orgasms that left some of them speechless.&nbsp; So what would it be like to be the woman?&nbsp; To have some man pounding into you?&nbsp; He put himself mentally into the woman's position and came nearly immediately.&nbsp;

&nbsp;

The next time, he started in the woman's position from the beginning and found himself rock hard within moments.&nbsp; And the next time.&nbsp; And the time after that.&nbsp; Soon, he found himself glancing at men and wondering - was it that man that was fucking "her" from behind?&nbsp; Or this other man?&nbsp; He sometimes wondered what it'd be like to kiss one them, to feel their hands on his body.&nbsp; At first, he'd jerk himself back from the recollections with shame and the next time he'd masturbate, he was the one doing the fucking.&nbsp; But, slowly, he'd wonder again and the next attractive man might end up being on the face of the man in his imagination.

&nbsp;

Eventually the lines blurred and he didn't feel as ashamed.&nbsp; He caught himself staring at men more and more - the way they walked, their ass and legs, their mouths... and their crotch.&nbsp; Were they big or small?&nbsp; Would they fill him... "her" up?&nbsp; Would it hurt in a good way?&nbsp; It was always "her" when he masturbated, never him.&nbsp; He never imagined himself as a man getting fucked from behind.&nbsp; But, slowly, he wondered if that's how it might be.&nbsp; He didn't have an "Ahah!" moment where he shouted, "HEY!&nbsp; I'm gay!&nbsp; The universe makes sense now and everything is all right!"&nbsp; He simply found himself thinking that, yeah, maybe there was something to it.

&nbsp;

He still liked women.&nbsp; He still wondered what some women would look like naked and he still imagined fucking them - and got hard thinking about it.&nbsp; But, sometimes he'd imagine a woman naked and think, "Yeah, I'd like to fuck the hell out of her." but then go to bed without masturbating.&nbsp; If he made the mistake of letting his mind wander over being the faceless woman on "her" hands and knees then he always had to masturbate.&nbsp; The visuals and feelings were too intense to ignore.&nbsp; So, perhaps not gay but at least bisexual.&nbsp;

&nbsp;

"At least" bisexual.&nbsp; He sighed again.&nbsp; Part of him coming here today was to give himself time to think.&nbsp; Exercise always focused his mind.&nbsp; He glanced at the woman again and found her staring at his crotch.&nbsp; He felt his own hard-on and ground his teeth.&nbsp; Apparently the exercise didn't focus his mind enough; he'd been thinking about it again.&nbsp; Greg hit the emergency stop button and got off to walk around.&nbsp; It didn't help that his teeth hurt.&nbsp; Or his gums.&nbsp; One of them did.&nbsp; He'd been grinding his teeth since the night before and it'd kept him up.&nbsp; He did his best to keep his eyes off of the other guys around him while he did his upper body workout.

&nbsp;

The weights felt strange as he worked through his sets.&nbsp; Sometimes he couldn't lift as much as he had before and sometimes he could lift more.&nbsp; Twice he had to have a guy help to spot him because he felt twitchy - never a good thing when lifting heavy weights above your own face.

&nbsp;

When he finished his routine he still felt restless and his gums itched.&nbsp; He'd been in a few fights when he was younger and more stupid and this felt a little like that.&nbsp; He wanted to hit something over and over until he couldn't breathe anymore.&nbsp; The gym had an area with a few heavy bags but he'd never messed with them before.&nbsp; Now he was interested.

&nbsp;

He heard some light thudding sounds coming from the room as he got closer to it.&nbsp; Greg stopped at the entrance to the room.&nbsp; A slightly built man was jabbing at one of the larger bags.&nbsp; The man was perhaps 5 feet 8 inches to Greg's 6 feet 2 inch frame.&nbsp; Where Greg was solid, this man was built smaller but in better shape - it looked like he had barely any fat on him.&nbsp; Whip-like.&nbsp; He worked around the bag, sometimes stepping back, sometimes in and sometimes weaving his upper body in a tight circle while he worked the bag.&nbsp; Sweat flew off of him when he punched and he breathed out sharply with a 'shh!' sound each time.&nbsp; He looked young but Greg couldn't place his age.&nbsp; Boyish.&nbsp; Maybe twenty-two?

&nbsp;

Greg walked over to an empty bag before his brain could take that thought process any further.&nbsp; He glanced back at the other man and then took what he imagined to be a fighting pose.&nbsp; He lurched forward to punch the bag and then again.&nbsp; The impact of his fist on the bag was satisfying in a way he hadn't known before.&nbsp; Soon he was pounding away at the bag left and right.

&nbsp;

A voice stopped him.&nbsp; "Ummm..."

&nbsp;

Greg caught the wildly swinging bag and turned to face the smaller man.&nbsp; "Hey.&nbsp; What's up?"&nbsp; He asked.

&nbsp;

"Well, it's probably none of my business but it looked like you haven't worked a bag before.&nbsp; I thought I might offer some advice.&nbsp; If you cared.&nbsp; If not, I'll apologize and let you get back to it."

&nbsp;

Greg took a couple wheezing breaths.&nbsp; "No... No, please do.&nbsp; I just... It's my first time trying it."

&nbsp;

A grin split the other man's face and Greg had to grind his teeth again.&nbsp; The guy wasn't handsome, he was... almost cute.&nbsp; He had a dash of light freckles across his nose and face and a heart-shaped face under a mop of unruly red hair.

&nbsp;

"I could kind of tell."&nbsp; The man said.&nbsp; He stuck out his wrapped hand.&nbsp; "Thomas.&nbsp; Pleased to meet you."

&nbsp;

"Greg.&nbsp; My pleasure.&nbsp; Now, what am I doing wrong?"

&nbsp;

The guy laughed.&nbsp; "Oh, everything!&nbsp; Here, let's start with how you stand.&nbsp; I'll just run you through some basics."

&nbsp;

He **had** been doing everything wrong.&nbsp; Thomas warned him to keep his wrists straight and not to lean into the punch.&nbsp; From there, they worked on his stance (left hand leading, legs apart) and the way he stepped.&nbsp; Greg lost himself in the instruction.&nbsp; "I guess I always thought you just punched."&nbsp; He told Thomas.

&nbsp;

"Oh, well, yeah.&nbsp; That's one way to do it.&nbsp; You're a big fella so that might work for you but someone smaller like me could take you out if they knew a bit of boxing or some other martial art.&nbsp; Small and fast, that's they way I do it.&nbsp; Well, haha!&nbsp; Not all small."&nbsp; He grinned again and Greg had to look away.&nbsp; His heart was racing in his chest and it wasn't from punching the bag.&nbsp; "Besides," the man told him.&nbsp; "I can't seem to build much bulk so that's what works for me."

&nbsp;

"Yeah.&nbsp; Hey, thanks, I appreciate it.&nbsp; Have you been boxing long?"

&nbsp;

"About nine years.&nbsp; Started when I was a Sophomore in high school.&nbsp; I haven't done anything beyond spars but I try to keep it up for the exercise.&nbsp; And if I ever have to get in a fight, it'll help.&nbsp; You never know.&nbsp; Just hard to find a place with boxing equipment whenever I move around.&nbsp; I was lucky there was one here."

&nbsp;

Greg took a few experimental punches, trying not to make the bag swing too much.&nbsp; "Oh yeah?&nbsp; Did you just move here?"

&nbsp;

"Yup.&nbsp; Last week.&nbsp; I'm renting a little house near the edge of town.&nbsp; I haven't even finished unpacking yet."&nbsp; Thomas shrugged.&nbsp; "I got my bed, couch and TV and that's the important stuff.&nbsp; I'm going to hit the showers and head out.&nbsp; It was nice meeting you!&nbsp; Maybe I'll see you around next time?"

&nbsp;

Greg closed his eyes against the 'shower' comment.&nbsp; He turned his back to the man to hide his boner.&nbsp; He knew what the problem was - Thomas was cute in a nearly androgynous way that blurred the line between man and woman.&nbsp; He grunted and punched the bag, hard.&nbsp; "Yeah, definitely!&nbsp; Thanks again for showing me the ropes.&nbsp; I'll just be here for a while."&nbsp; He didn't watch the other man leave and he cursed himself for his lack of manners.

&nbsp;

When Thomas was gone, Greg pounded away at the bag.&nbsp; He was a tolerant man and, aside from unthinking comments when he was a child, had nothing against homosexuality.&nbsp; It was just that it had never applied to him.&nbsp; He felt confused and seeing this young man didn't make it any better.&nbsp; "And my goddamned teeth hurt!" He roared.

&nbsp;

Another voice answered him.&nbsp; "Maybe you should go see a dentist?"&nbsp; Greg spun as his face turned crimson.&nbsp; A large black man was watching him curiously.

&nbsp;

"Oh man.&nbsp; I'm sorry - I thought I was alone.&nbsp; Haha!&nbsp; Yeah.&nbsp; I should.&nbsp; I'll let you have the room.&nbsp; Sorry again about that!"&nbsp; The black man cocked an eyebrow at Greg while he made his way out.

&nbsp;

"Goddamn fool."&nbsp; Greg muttered to himself.&nbsp; As he left the room, he caught sight of Thomas walking through the front doors.&nbsp; Greg walked fast to catch up to him outside.

&nbsp;

"Hey!&nbsp; Thomas, hey!"

&nbsp;

The younger man stopped at his car and turned, a slight smile on his lips.&nbsp; "Greg, howdy."

&nbsp;

"Hey, man.&nbsp; I'm sorry - I wasn't ignoring you in there.&nbsp; That was shitty of me.&nbsp; No, really.&nbsp; Here, you're new in town.&nbsp; Let me treat you to dinner to apologize and I'll give you all the town gossip while I'm at it.&nbsp; The little that I know.&nbsp; Just wait for me and I'll grab a quick shower.&nbsp; Okay?"

&nbsp;

Thomas' smile widened a little further.&nbsp; "I'd like that."

&nbsp;

Greg's face nearly flushed as he ran back to the showers.&nbsp; "Stupid, dirty old man."&nbsp; He told himself.

&nbsp;

An hour later he was seated across from Thomas in the nearby Red Apple diner.&nbsp; It was a slow evening and they had the corner to themselves.&nbsp; Their waitress was a thin girl that seemed more interested in texting than in giving them service.&nbsp; Neither of them cared that much.&nbsp; Greg felt oddly at ease in the other man's company and was enjoying their mindless conversation.

&nbsp;

"So why boxing?"&nbsp; Greg asked at one point.

&nbsp;

Thomas watched him for a moment.&nbsp; "I got tired of being defenseless.&nbsp; I needed an outlet."

&nbsp;

"An outlet?&nbsp; For what?"

&nbsp;

"I'm gay.&nbsp; The town I lived in wasn't very tolerant so I got bullied.&nbsp; My own parents gave me shit so it was either kill myself or find an outlet.&nbsp; I'm not particularly tired of life yet so I picked boxing.&nbsp; I got in shape, worked out my frustrations and learned to ignore everyone else.&nbsp; The coach was a good guy, more like a father to me after a while.&nbsp; Taught me that most people out there bullying was because they were insecure about themselves.&nbsp; Or ignorant.&nbsp; And he taught me a good trick."

&nbsp;

Greg's heart skipped a few beats.&nbsp; "What trick?"

&nbsp;

"Hah.&nbsp; He told me to imagine the assholes with a dick for a tongue whenever they were mouthing off to me.&nbsp; It helped.&nbsp; Although I laughed once and got the shit kicked out of me for my trouble.&nbsp; If it were a boxing ring with boxing rules, I might've had a chance but three kids is a bit much and kicking is against regulations."&nbsp; The corner of Thomas' mouth curled up in a little wry grin.&nbsp; Greg smiled with him.&nbsp; "I notice you're still sitting there."&nbsp; Thomas said.

&nbsp;

"What?&nbsp; Oh... Oh!&nbsp; About you being gay?&nbsp; I don't care.&nbsp; You seem like a cool guy and that's what matters.&nbsp; Who cares who you sleep with, right?"

&nbsp;

Thomas watched Greg carefully.&nbsp; "Right."&nbsp; His eyes seemed to bore into Greg's eyes.&nbsp; "Who cares who it is."

&nbsp;

The silence was heavy and pointed.

&nbsp;

Greg felt a bead of sweat slip down his temple.&nbsp; "Actually, I..."

&nbsp;

"Who had the hamburger?"&nbsp; Their waitresses magically appeared at their table with two plates in her hands.

&nbsp;

Greg nearly swallowed his tongue.&nbsp; "I did.&nbsp; Thanks."

&nbsp;

The waitresses turned away after setting their plates down, already typing on her smart phone.&nbsp;

&nbsp;

Thomas carefully bent over his pasta, ignoring Greg's cut-off sentence.&nbsp; Greg mentally cursed himself.&nbsp; _What was I doing?&nbsp; What were you planning on doing there, Greg?_&nbsp; He asked himself.

&nbsp;

They both finished their meals in silence, lost in their own thoughts.&nbsp; When the check came, Greg picked it up while ignoring Thomas' grumbles.&nbsp;

&nbsp;

"It's on me.&nbsp; I felt like a dick back at the gym.&nbsp; Hey, do you need help unpacking?&nbsp; I don't have anything else to do tonight and wouldn't mind being out of the house.&nbsp; I've been feeling cooped up with nothing to do all day.&nbsp; My hands itch to do something.&nbsp; Work, I mean."

&nbsp;

Thomas grinned again.&nbsp; "Yeah, that'd be cool.&nbsp; Just follow me.&nbsp; It's a pretty short drive.&nbsp; And, thanks for the meal.&nbsp; I haven't really met anyone here yet.&nbsp; I'm glad to know I didn't move somewhere bad again."

&nbsp;

On the ten minute drive to Thomas' house, Greg's heart tried to beat out of his chest.&nbsp; "What are you doing, Greg?"&nbsp; He asked himself out loud.&nbsp; "What are you doing?"&nbsp; His hands twitched on the steering wheel and he shrugged his shoulders while trying to itch his back on the fabric seat covers.&nbsp; "This is stupid."

&nbsp;

His dick was hard the entire ride.

&nbsp;

There was a muddy path leading to the house and Greg's little car almost got stuck at one point.&nbsp; He almost turned around but couldn't bring himself to do it.&nbsp; Thomas waited for him at the door.

&nbsp;

"Don't mind the mess."&nbsp; He told Greg.&nbsp; Inside the little white house were piles of boxes, a couch and a small LCD TV.&nbsp; "Welcome to my home, such as it is."&nbsp; Thomas held his arms out and twirled slowly.&nbsp; "I'll give you the tour.&nbsp; This is the kitchen.&nbsp; My microwave is in one of the boxes.&nbsp; The bathroom is there to your right.&nbsp; Keep the lid up or down if you want.&nbsp; I don't care.&nbsp; And the bedroom.&nbsp; Just the mattress at the moment.&nbsp; I'll get a bed frame one day when I settle down."&nbsp; There were a stack of books in the corner of the room next to the bed.&nbsp; They were all paperbacks with old, worn down covers.&nbsp; A smart phone dock was the only thing plugged into the walls of the bare room.&nbsp; Clothes were piled in the corner.

&nbsp;

They made their way back to the living room.&nbsp; "Have a seat."&nbsp; Thomas told him. "Want something to drink?&nbsp; I have some local beers, water, juice...?"

&nbsp;

Greg swallowed.&nbsp; "A beer would be fine.&nbsp; Thanks."&nbsp; He sat on the old couch, sinking into the cushions.&nbsp; Thomas hustled out, clinking around in the kitchen before coming back with a bottle of dark beer.

&nbsp;

"Here you go."&nbsp; He said.&nbsp; "So..."

&nbsp;

Greg took a sip and then looked up at the other man.&nbsp; "So...?"&nbsp; His arms itched so he scratched himself with one hand.

&nbsp;

Thomas cocked his head to the side, staring at Greg as if he were a puzzle to be solved.&nbsp; "So did you really come here to help me unpack?"

&nbsp;

Greg took another sip of the beer.&nbsp; "I... At first I did but... I don't know anymore."&nbsp; He stared at his hands.&nbsp; Thomas watched him quietly.&nbsp; Greg took a few more sips and then slowly told the story of how he found himself becoming attracted to men.&nbsp; "And then I saw you and, I don't know.&nbsp; You're... cute."

&nbsp;

"You mean I remind you of a woman a little bit."&nbsp; Thomas told him.

&nbsp;

"Yeah.&nbsp; Yeah, I'm sorry.&nbsp; Is that bad?"

&nbsp;

"No, not at all.&nbsp; Do you mind if I sit?"

&nbsp;

Greg looked back up.&nbsp; "It's... No.&nbsp; It's your house.&nbsp; Go ahead."

&nbsp;

Thomas sat close to Greg and set his beer on the floor.&nbsp; "Does it bother you?&nbsp; These feelings?"&nbsp; He asked.

&nbsp;

Greg shook his head.&nbsp; "No.&nbsp; I'm just confused.&nbsp; I still like women but lately, I've been turned on more and more by guys.&nbsp; It's been nearly half a year since I first started wondering about it and the feelings just get stronger.&nbsp; Is that how it worked for you?"

&nbsp;

Thomas crossed his legs at his ankles and leaned back against the couch.&nbsp; "Oh, no.&nbsp; I've always known I liked boys.&nbsp; You, you're just bi and it took you a bit of time to realize it.&nbsp; So, why did you come here, Greg?&nbsp; Do you want to talk about it?"

&nbsp;

"I don't...&nbsp; I..."&nbsp; Greg's heart beat hard against his chest.&nbsp; He swallowed several times to try and wet his throat.

&nbsp;

Thomas leaned forward and held out his hand.&nbsp; "Let me have your hand."&nbsp; Greg reached out hesitantly to Thomas.&nbsp; Thomas' hand felt cool but firm against Greg's own hand.&nbsp; "Now look at me.&nbsp; One of the worse things our society does is to repress our emotions.&nbsp; Our desires."&nbsp; Thomas slowly leaned closer to Greg.&nbsp; Greg felt hypnotized by the words and Thomas' blue eyes.&nbsp; "We tell ourselves, no, this isn't right.&nbsp; It shouldn't be this way.&nbsp; Don't do that, do this.&nbsp; This isn't moral, that is.&nbsp; Listen to them, not to yourself."&nbsp; He leaned closer still.&nbsp; "And what does that do?&nbsp; We bottle up our true feelings until something breaks.&nbsp; And then?"&nbsp; Thomas' lips were an inch away from Greg's own lips.&nbsp; Amazingly, Greg could feel his heart beat slowing as he stared at this beautiful young man.

&nbsp;

"Something breaks."&nbsp; Thomas whispered.&nbsp; He leaned in and lightly kissed Greg on the lips.&nbsp; Greg's eyes widened and he pulled back.&nbsp; Thomas watched him, eyes a little sad.&nbsp; "Are you broken, Greg?"

&nbsp;

Greg's thoughts raced.&nbsp; _I just kissed another man._&nbsp; He told himself.&nbsp; _I just kissed another man.&nbsp; I just..._&nbsp; He swallowed again.&nbsp; "I..."&nbsp; The itch from his arm felt like it was spreading to his back.

&nbsp;

"Can I kiss you?"&nbsp; Greg asked.

&nbsp;

"Do you want to kiss me, Greg?"&nbsp;

&nbsp;

"Yes.&nbsp; Yes.&nbsp; I do."

&nbsp;

"Then kiss me, Greg."

&nbsp;

Greg set his beer on the floor and leaned over to pull Thomas closer to him.&nbsp; He cradled the young man's head in his large hand and pulled his mouth to his own.&nbsp; A small voice was screaming at him in the back of his head but he ignored it.&nbsp; He kissed Thomas, lightly at first and then harder.&nbsp; When he opened his mouth, Thomas opened his own.&nbsp; Their tongues touched and then writhed together.

&nbsp;

_Warm.&nbsp;_ Greg thought.&nbsp; _Just like a woman.&nbsp; No.&nbsp; Just like a person._&nbsp; Thomas' hand reached for Greg's thigh, gripping him while they kissed.&nbsp; Greg growled deep in his throat.&nbsp; He brought his hands around to lift the other man up into his lap but Thomas shifted himself to help.&nbsp; They broke their kiss apart briefly but Greg pulled him back in.&nbsp; His cock pressed hard against his pants while the other man sat on his thighs.&nbsp; Greg's hands gripped Thomas' back, pulling and gripping over and over.

&nbsp;

They broke apart breathlessly.&nbsp; Thomas wiped his mouth with the back of his hand.&nbsp; "You okay?"

&nbsp;

Greg nodded, wordlessly.&nbsp; His lips jumped near his nose.&nbsp; He wanted to rub his whole back over the couch.&nbsp; His skin felt strange but he couldn't ignore what was happening right now.&nbsp; Greg put his hands under Thomas' shirt and then stopped to look at him.&nbsp; Thomas nodded slightly and Greg pulled the other man's shirt above his head.&nbsp; The younger man had a strong but thin body and was completely hairless.&nbsp; Greg's hands slowly explored the other man's chest.

&nbsp;

"Do you like what you see, Greg?"&nbsp; Thomas asked.&nbsp; The man placed his hand on Greg's erection and leaned forward next to Greg's ear.&nbsp; "He likes what he sees."&nbsp; Thomas whispered.

&nbsp;

Greg shuddered and put his mouth on Thomas' nipple, flicking it with his tongue over and over.&nbsp; Thomas writhed in his lap, moaning softly.&nbsp; Greg's fingers undid the button of Thomas pants and, this time, he didn't ask if it was okay first.&nbsp; Thomas sat back on the couch and together they pulled his pants off.

&nbsp;

Thomas' body was completely hairless, even his crotch.&nbsp; His erection was a modest six inches and it throbbed in the air.&nbsp; Greg watched it move.&nbsp; Thomas took Greg's hand, pulling it to his dick.&nbsp; "It's okay, Greg.&nbsp; It's okay."&nbsp; Greg touched Thomas' dick carefully.&nbsp; He was circumcised like Greg was but slightly smaller and a little more thin.&nbsp; He tugged gently on the shaft and Thomas moaned.&nbsp; "Mmmm, yes, like that."

&nbsp;

Greg's nose twitched.&nbsp; There was a strong smell in their air.&nbsp; He knew the smell of cum from his own dick but this wasn't it.&nbsp; There was... something else.&nbsp; His mouth burned.&nbsp; He wanted to bite something.&nbsp; He leaned forward and rubbed the dick against his rough cheek.&nbsp; Thomas' balls hung slightly loose and he buried his nose in the soft flesh of them.&nbsp; Thomas put his hands in Greg's hair.&nbsp; Slowly, Greg licked the flesh around the balls.&nbsp; Experimentally.&nbsp; And then again.&nbsp; Tentatively, he opened his mouth and gently pulled the balls into his mouth to suck on.&nbsp; Thomas shuddered above him.&nbsp; "Yesssss..."&nbsp; He said.&nbsp; Greg's hand worked up and down on Thomas' dick.&nbsp; A small amount of precum trailed down the tip to touch his hand.

&nbsp;

Greg worked his tongue gently around the balls in his mouth, feeling them shift and move.&nbsp; He knew how sensitive they could be and the urge to bite was nearly overpowering so he pulled off.&nbsp; The smell in the air was making him drool.&nbsp; He wanted.&nbsp; With no hesitation, he pulled Thomas' dick into his mouth.&nbsp; When he tried to go down completely, he nearly gagged so he backed off.&nbsp; Thomas let out a soft "Oh!" before gripping Greg's hair.&nbsp; Greg slowly pulled the cock into his mouth, working his tongue around the shaft.

&nbsp;

"No... oh god, no teeth... no... oh oh... no teeth..."

&nbsp;

Greg pulled his teeth back and used his lips and tongues to caress Thomas' cock.&nbsp; With one hand, he pumped the shaft while he pulled his head up and down on the man's dick.&nbsp; He could taste the salty pre-cum but it didn't bother him.&nbsp; He wanted more.&nbsp; His own erection throbbed painfully in his pants and he wanted this man to cum in his mouth.&nbsp; The smells, the taste, the sex, the raw sex, he wanted it all.&nbsp; He pumped the cock harder and sucked on the tip of the man's penis.&nbsp; He worked his way back down and then up, licking and sucking.&nbsp; Thomas cried out as he came suddenly.&nbsp; Greg swallowed the salty load several times until his mouth was clear.

&nbsp;

"Fuck!&nbsp; Fuckfuckfuck!"&nbsp; Thomas screamed.&nbsp; "I'm sorry!&nbsp; I'm so sorry!&nbsp; I didn't mean..."

&nbsp;

Greg pushed him back on the couch and stood, taking off his own shirt.&nbsp; His fingers itched to claw the hairless flesh beneath him.&nbsp;

&nbsp;

"Are you... are you growling?&nbsp; Are you okay?"

&nbsp;

Greg grinned.&nbsp; "More than okay.&nbsp; Undo my pants for me."

&nbsp;

Thomas leaned forward eagerly, his flaccid penis still dribbling cum.&nbsp; His fingers worked deftly and soon Greg was stepping out of his own pants.&nbsp; Greg's own body was covered in hair.&nbsp; His chest was thick but soft with hair but he kept his cock trimmed when he could.&nbsp; Thomas grabbed Greg's eight inch dick and leaned forward to suck on it.&nbsp; Greg grabbed Thomas' hair and pulled him back.&nbsp; "No."&nbsp; He growled, his lips pulled back to show his teeth.&nbsp; Thoughts were hard with the smell in the air but he burned with need.&nbsp; "I want to fuck you.&nbsp; Give me your ass."&nbsp; Thomas' face flushed with excitement.&nbsp; Greg could see the other man's dick trying valiantly to grow hard again.

&nbsp;

Thomas spit on his hands and rubbed Greg's dick down.&nbsp; He leaned forward on the couch with his ass in the air.&nbsp; From here, he **did** almost look like a woman.&nbsp; His skin was very white and nearly unblemished.&nbsp; Greg could almost imagine he was fucking a woman.&nbsp; But, he didn't want a woman.&nbsp; He wanted this man.&nbsp; His dick ached for release.&nbsp; Greg grabbed Thomas' ass and pulled the cheeks apart.&nbsp; Thomas reached around to grab Greg's dick but Greg growled again and pushed the man forward.&nbsp; His teeth yearned to bite something.&nbsp; Greg kept one hand on Thomas' ass and, with his other, he guided himself to Thomas' asshole.&nbsp; At the entrance, he paused.&nbsp; Thomas wriggled slightly against him, moaning in anticipation.

&nbsp;

Greg, still growling, pushed himself in slowly, hissing his breath out as Greg's ass wrapped around his cock.&nbsp; Thomas' dick sprang to life and the man bit into the fabric of the couch as he moaned.&nbsp; Greg grabbed Thomas' hips and pulled himself out slowly.&nbsp; The feeling was incredible.&nbsp; He pushed in again but stopped before their hips touched.&nbsp; His fingertips dug into Thomas' flesh, kneading him over and over as he pulled out again.&nbsp; He couldn't hold himself back any longer.&nbsp; He grabbed Thomas' muscular side with one hand to pull him into a slightly upright position.

&nbsp;

Greg leaned forward and bit Thomas, hard on the shoulder.&nbsp; Thomas shrieked and tried to bury himself on Greg's cock.&nbsp; Greg could taste blood in his mouth and he growled at the smell of it.&nbsp; He started pounding into the other man, his mouth still locked on Thomas' shoulder.

&nbsp;

"Oh god!&nbsp; Oh Jesus H. Christ! Yes!&nbsp; Greg! Yes!"&nbsp; Thomas shouted.&nbsp; Greg licked the blood off of Thomas' shoulder and leaned back to concentrate on fucking the other man.&nbsp; Tendons strained on his arms from the effort of holding himself back.&nbsp; His whole body felt like it was on fire.&nbsp; He licked his lips in a circle, tasting blood and cum as he did.&nbsp; His canine teeth felt sharp, sharper than they'd ever been.&nbsp; He roared as he plunged, fucking the other man.

&nbsp;

"W...wait... not so... wait!"&nbsp; Greg's hips slapped against Thomas.&nbsp; "It hurts!&nbsp; Wait!"&nbsp; Black hairs stood out on Greg's arms as muscles bulged.&nbsp; He could feel his fingernails cutting into the other man as he buried himself up to his balls.&nbsp; He didn't notice the blood as he pulled out.&nbsp; All Greg knew was fucking - fucking this man in front of him.&nbsp; The hairs ran in a wave up his arms to his shoulders and then down his back, a fine carpet of black hair mingling with his body hair.

&nbsp;

His back cracked, forcing him to howl in pain.&nbsp; He didn't stop pounding.&nbsp; Muscles bulged along his biceps.&nbsp; His shoulders spread apart, pulled by muscles growing along his spine.&nbsp; He liked his mouth, touching his nose as his tongue grew.&nbsp; His nose felt cold against his hot tongue, cold and wet.&nbsp; He could see his nose pushing in front of his face, cracking his jaw as it did.&nbsp; Sharp teeth grew to replace molars as they fell out.&nbsp; More teeth filled the gaps as his face grew into a muzzle.&nbsp; Black fur ran up his neck to cover his face.&nbsp; When he licked his muzzle from the effort of fucking the little man in front of him, his lips and nose turned black.&nbsp;

&nbsp;

Thomas was screaming in front of him but Greg didn't notice.&nbsp; Mating was Greg's only concern.&nbsp; Fucking.&nbsp; Scents were overpowering.&nbsp; His needs left no room for thoughts.&nbsp; He ran his right hand down Thomas' back and the thick black claws drew lines of blood on the white skin.&nbsp; A thick tuft of fur grew out from Greg's crotch, covering the base of his cock.&nbsp; The fur grew up the base of his cock to create a sheath around him.&nbsp; The base of his dick bulged and then grew into a knot as the skin turned a bright red color.

&nbsp;

Thomas no longer screamed - he was grunting in effort.&nbsp; Red hairs sprouted from his back as the cuts from Greg's claws healed over.&nbsp; With a small 'pop' a bulge started at the base of Thomas' spine and slowly grew into a hairless tail, pressing against Greg's stomach.&nbsp; Greg watched as Thomas' hands convulsed over and over.&nbsp; Fingernails were pushed out as thick black claws grew from the tips of the man's fingers.&nbsp; Thomas had his face half-turned in a grimace of pain or pleasure.&nbsp; The man's jaw broke and then grew out into his own muzzle.&nbsp; When he opened his eyes, they were a deep coppery bronze color.&nbsp; Thomas slammed back against Greg.

&nbsp;

Greg gripped Thomas.&nbsp; The other man's ass grew as new muscles set in.&nbsp; Fur crept down from his back to cover his ass and then his tail.&nbsp; The fur along the tail sprouted long and thick and soon the red wolf tail was curled up and back against Greg's furry stomach.&nbsp; Thomas' long tongue panted from the effort of the transformation.

&nbsp;

Greg felt his own tail set in.&nbsp; A tugging at his spine announced it but he paid it no mind as his plunged his thickening cock into Thomas.&nbsp; The knot at the base of his dick dipped into the other man's ass with every push.&nbsp; Greg's feet grew, placing him on his toes.&nbsp; The claws of his toes dug into the carpet for purchase.

&nbsp;

_Almost._&nbsp; A small voice said at the back of his head.&nbsp; _Almostalmostalmostalmost..._

&nbsp;

Muscles lined Thomas' red furred body.&nbsp; The young man was yipping in pain as the change finished and pushing back harder and harder as he clawed the couch to shreds.&nbsp; With a final, hard push, Greg's knot rammed into Thomas' ass.&nbsp; Thomas came again, thick spurts of cum shooting from his own knotted wolf cock beneath him, covering the couch.&nbsp;

&nbsp;

Greg growled in anger, grabbing Thomas' muscled furry shoulder, bearing down on him.&nbsp; With a renewed effort he slammed into the man over and over until, finally, his own release brought him nearly to his knees.&nbsp; He pulled his head back into a silent howl before biting down on Thomas' shoulder to feel the bones grind beneath his teeth.

&nbsp;

He collapsed on top of the smaller man, black fur against red.&nbsp; His dick throbbed, still completely hard.&nbsp; Thomas pulled slightly but Greg's knot kept him in place.&nbsp; Greg growled tiredly in response.&nbsp; The young man twisted slightly to lick Greg's fur-tipped ears with his long tongue.&nbsp; In response, Greg reached around to grab Thomas' now eleven inch knotted dick.&nbsp; He pumped the dick in it's furry sheath slightly as he rubbed his head against Thomas' head.

&nbsp;

Thomas whined in anticpation.
