#1 of Terri's Secret


"So I'll see you around nine? Right? Okay. See you then." Terri hung up the phone and sighed deeply. She was already getting excited for the sleepover tonight and shooed the perverted images from her mind.

Her eighteenth birthday had been last weekend; however, this was the first time she and her friends were able to get together. She had a lot of fun things planned for tonight, some of which were innocent enough. She didn't think they start getting dirty until midnight, but she wouldn't protest if things moved ahead of schedule.

Brittany arrived first with a cake. She was a tall skinny blond and could get a porn shoot by walking into a studio unannounced if she wanted. Her top strained to hold her large DD-breasts. By the pinpoints poking from the globes on her chest, she was either wasn't wearing a bra, or was as excited about tonight as Terri was. Either was just fine in Terri's mind. She didn't plan on staying fully clothed for very long anyway. In fact, not only was she not wearing a bra, she had foregone all undergarments.

Terri said hello and told her to put her gifts on the table in the kitchen and make herself comfortable.

Ginger and Loni were next, toting large bags from Macy's. Terri expressed interest, but they told her she'd have to wait. She was disappointed, but understood, and let it slide.

Ginger swayed as she walked, with or without heals, and almost never wore lingerie. Practical or erotic, it didn't matter. She wouldn't wear it. Said it was uncomfortable. Guy figured her for a tease, seeing how her nipples would always show through the fabric of the shirts she wore. Loni, on the other hand, was flat-chested, skinny as a tree-branch, and the most conservative of all of Terri's friends. The reason she was invited was three-fold. One, her inhibitions went by the wayside after a few drinks. Two, the plans she had for tonight would make her think twice about her appearance. Moreover, she was her best friend; I just wouldn't be the same without her.

"There aren't going to be boys here, are there?" Loni said as she passed Terri. Terri thought for a moment, and then said, "No," and left it at that.

With everyone here, Terri kicked the party in to gear. They started by talking about boys they like, and boys they didn't, and the boys that can't seem to get a clue. Terri remained silent during the conversation, so it wasn't long before she brought out the booze.

Loni declined at once.

"Loni, you can't be such a priss," Ginger said. "This is a celebration; we can have a toast with out everyone participating."

Realizing she was bringing the party down, Loni grabbed the shot glass of Patron, and held it shakily in her hand.

"Good. Now, to Terri, most beautiful legal princess in the world." They clinked their glasses and downed the clear liquid.

They laughed as they slammed their shot-glasses on the glass coffee table.

The clock chimed eleven times. One more hour to go, Terri thought. Time to loosen them up. "What say we get a bit more comfortable," she said with a devilish grin on her face.

Ginger and Brittany giggled; a mix of alcohol and the opportunity to strip sent a shiver from head to toe. Loni didn't giggle. She sat in her spot feeling the warmth of the high-octane liquor engulf her. The heat reached her loins and she shuddered.

It didn't go unnoticed. "Looks like Loni's finally joining the party," Brittany said.

"Give her some time," Loni said. "She'll come around soon."

Loni sat there, hating herself for letting them drag her into this whole mess. Too late for self-pity. If you can't beat them, fuck it. She laughed abruptly at her wit and the three girls jumped. Loni hick-upped, snorted, and then reached for the large bottle of Patron. She poured herself another shot as well as one for Brittany, Ginger, and Terri. She raised it in a toast and said, "Well, what are you waiting for? To Amnesia. Let us have so much fun that we won't remember what the fuck we did."

After a moment of silence, they all laughed. "I'll drink to that," Ginger said.

They raised their second shot, counted to three, hit it, and then slammed the empty glass on the table.

The party kicked into high gear then. Brittany thought it would be a good idea to compare breasts. Of course, she won with her titanic globes. Loni, ironically, got the booby prize for the smallest chest: she got to suck on the winner's tits.

Ginger picked the next game: an erotic version of Truth or Dare. The rules were simple: Pick Truth or Dare and suffer the consequences. The Truths had to be related to intimate or sexual encounters and the Dares had to involve an erotic or sexual activity. They also had a rule that perchance there was a prude in their midst, that person was only allowed to elect the Dare option.

The prude in this case was Loni.

Terri started first. She asked Brittany the obligatory question.

"Dare," she said.

"I dare you," Terri started, rolling her eyes in thought, "to eat Loni out to orgasm."

Brittany looked over to Loni. Loni appeared frightful, but it didn't last long. Brittany spread Loni's legs and rubbed a hand over the cloth of her panties. She traced an indentation at her vertical smile forming a beautiful cameltoe. Her mound puffed out more on each pass of Brittany's delicate hand.

Loni sat back on her hands, and tilted her head back. She started to moan.

Brittany slid her fingers under the waistband of her panties and slid them down Loni's legs, leaving them wrapped around her ankles. She rubbed Loni's swollen rose petals, tracing her middle finger along her gash. She teased her, avoiding slipping her longest digit into her.

Loni was moaning louder now and squeezing her tits.

Brittany lowered her head letting her long blond hairbrush against Loni's clit. Loni gasped as Brittany latched her lips on Loni's button. Brittany continued to lick and suck at Loni's clit, alternating between that and darting her tongue in her pussy.

Loni whimpered, moaned, groaned, and gasped, as pleasure waves flowed through her at a constant, unrelenting, pace. "I'm cumming," she whimpered. "I'm g-gonna c-cum, s-ss-soon."

Ginger and Terri had stripped in the meantime and were making out, moaning, and gyrating their hips against each other. They were a two-headed serpent joined at the pussy.

Loni came with a scream. Brittany drank her love juice.

Terri and Ginger weren't finished. They moved to their own rhythm. Groaning and panting, soaring to new heights.

Terri didn't hear the clock chime midnight.

However, her body reacted just the same.

The changes were slight, at first. She became more feral with her movements. Ginger tried to keep pace, but soon was fighting for air.

Ginger gasped and shoved Terri off her. She looked at her arm. Terri had scratched her. Blood pooled but didn't spill over. It was as if the wounds were already healing. She stared in astonishment and horror, and then turned her attention to Terri, who sat in a heap, head down and a curtain of hair blocking her features.

Terri convulsed at short intervals, like a heartbeat. The convulsions sped up and the first signs of change appeared. The curtain of her hair pulled away from her lengthening face, revealing a lupine muzzle sporting razor sharp fangs. Her eyes glowed blue through the strands of hair still blocking some of her face.

She pulled the hair back completely, as if she wanted them to see her this way. Her hands were deformed; they were longer and narrower, and the thumbs had moved up to where her wrist was.

It was spellbinding. It was like watching a tidal wave make landfall, they wanted to run, but couldn't. Terri's changes continued. The fleshy muzzle sprouted a fine layer of fur. Fur sprouted all over Terri's body like a magical forest. It grew thick in areas and fine in others. Her pussy disappeared under the growth, only the slit of her opening remained visible. A large wolf-like tail flowed from her backside and she howled at the completion of her transformation.

Ginger ran to the bathroom when she felt her wound prickle. Fur grew from it instantly. Lucky for her, though, Loni and Brittany were too busy watching Terri turn into a monster to realize their friend Ginger was becoming one, too.

Ginger watched as her face pushed out into a wolf muzzle and doubled over as the fur spread. Her ankles cracked and snapped and she landed on all fours, as her heels became her ankles.

She roared upon completion and tried to stand. It was surprisingly easy. She pushed the bathroom door open and peered into the living room. There was blood on the carpet and Loni and Brittany were convulsing in fetal positions.

Moments later, Brittany and Loni's transformations were complete, and Terri said, "I am so glad I was able to share my gift with you, my closest of friends, on this, the most sacred of days."

The girls were speechless. Not from hearing their friend speak while in an alien body, or the fact that they all just did something completely extraordinary, but from the heat emitting from their loins. If it weren't for the fur, they'd be blushing.

"I understand your needs, girls, and I'm prepared to meet those needs. Come to my room and I will show you."

They followed Terri up the stairs and around the corner, to a back room. Terri locked the door behind her and opened the window. "We're ready for you boys," she called down from the open window and seconds later six male wolf-men entered via Terri's bedroom window.

"Where did they come from?" Loni asked the sentence fading as she noticed the large furry sheaths. They were bulging already. Only a little coaxing and their slippery red cocks would be in plain view.

"Does that matter, hon?" Terri said.

Loni shook her head and grabbed for the nearest male. He came forward and she started to rub his sheath until his cock came out. She stood and wrapped her muzzle around his and was lost. They pressed together, loin to groin. The male lifted her leg up and slid his prick inside her.

Their kiss broke as she gasped at the intrusion, and then went back to kissing, sliding up and down the male's growing member.

Terri invited the others to pick one of the males, as they were there to please them in any way they wanted. Brittany asked why there were six, when there were only four of them, by which Terri simply replied, "You'll have to find out."

In minutes, Terri's bedroom filled with the din of pleasure-soaked moans. Two of the males stood in the corner, pawing off as they watched the horny fems fucking their friends.

They rotated. The male with Loni switched out and one of the reserves took his place, the others switched partners as well. Again, the room filled with moans and groans as the wolf-men pumped their cocks in the girl's heated pussies.

Brittany rode her male, bouncing on his stiff member while he sat on the bed. Her large tits bounced in rhythm to her downward thrusts. Ginger was sucking off her male and raised her ass in invitation to a male pawing off in the corner. He was the only one who didn't have a turn yet. "Fuck me, wolfy-boy. Fuck me with your throbbing dick. I want to feel you inside me."

She wiggled her ass at him and swished her tail, fanning her musk in his direction.

The male nearly lost it right there. Wasting no time, he placed his prick by her opening and stopped, the head barely parting the folds of her flesh. She pushed back, and he stepped back, preventing her from penetrating him.

She scowled back at him. He sneered back. "You want this?" The male said.

She nodded, still sucking away on the male in front of her. She moaned her desire, sending waves over the dick in her mouth. The male that prick belonged to moaned in return.

The male behind her shoved his member into her yawning snatch, and started to pound her. His ball-sack slapped noisily.

She let the dick fall out of her mouth, moaning louder now. She licked the prick before her, but couldn't get enough air to stick it in her mouth again. The male at her pussy pulled out and nodded to the male in front of her face. Brittany didn't know what they meant to do until they flipped her over. One of them lay under her and placed his dick at her puckered asshole. The other lay on top, again sliding his red bone in her pussy.

Brittany didn't know what to do. She'd never done DP, let alone anal. It looked like she was going to break two milestones at once tonight. The male under her guided his head into her ass, sliding it in slowly. When he was in, he began to thrust in time with the male atop her.

Everyone else stopped to watch. One of the other males walked over to the moaning and panting fem and stuffed his prick in her mouth. Every hole filled, Brittany was in ecstasy.

"Ginger," Terri said. "There are three of them left, they're yours. I want to show Loni something."

The males surrounded her and Terri led Loni out of the room and down the hall.

Terri took Loni outside. She stopped in the middle of a large grassy area a few yards from the driveway.

Loni could feel her juices floor. She flushed despite her attempts to suppress the growing sensitivity between her legs. She placed her paw over her mound and rubbed it sensually.

Terri smiled, showing a good amount of fang, and nodded to someone standing behind Loni.

Two black hands cupped Loni's shoulders and spun her around. He was an ebony god. Handsome face, dynamite body, large flaccid cock. Loni looked down at this man's member and guessed it to be nearly eight inches limp. She had a hard time wrapping her mind around the size when erect. Loni reached for the prick, but the man stepped back. Frustrated, and longing for that massive member in her pussy, she made another attempt. The man backed up just out of reach.

"Patience, Loni," Terri said. "You two haven't been formally introduced. This is Stallion. He's your playmate tonight. Be warned, he is a lot larger than he appears. Are you sure you want to fuck Stallion?"

Loni nodded, unable to keep her eyes off of Stallion's member.

"Very well." Terri nodded.

Stallion changed...

His dick was the first change Loni noticed; it seemed to shrivel and fold. Then, a large sheath of skin extended from his pelvis, enveloping the flaccid prick. Loni stepped back to watch Stallion change into, well, a Stallion.

He stood erect at about six foot six, a large horse muzzle for a face and a long, dangling dick that had to be nearly a foot long.

Loni stood mesmerized, and then realized she was going to fuck this Stallion. She bent over and waited. Stallion didn't continue. She looked back, and saw unease on his face and realized that it probably wasn't safe without something to brace herself.

She walked over to the house, and then around it. "Is this good?" Loni asked as she leaned against the back of the house.

Stallion nodded.

"Good." She turned and faced Stallion, kissed him on his large horse lips and squatted to get her face in front of his dick. She grabbed it and it jerked instantly. She could feel the blood flow and watched it grow in her hands.

She licked the head. Stallion whinnied. The head mushroomed out and Loni was glad for her large wolf muzzle for the head was way too big for any human mouth. She placed the dick in her mouth and gobbled it up. She got nearly nine inches in before she started gagging. She kept up the pace and soon found that she was sucking only the tip.

Stallion stomped and whinnied and blew his load. Loni couldn't keep up with the flow of fluids pouring from Stallion's prick, let it fall out of her mouth and got a good sticky shower.

Stallion's dick went limp, but didn't pull back into the sheath. Stallion licked Loni on her muzzle and moved downward until he was at her pussy. He stuck his long equine tongue in her opening and Loni shuddered.

He started to lick faster and Loni began to moan. It felt like heaven.

After a few intense minutes of cunnilingus, Stallion stopped and Loni whined.

Loni gasped as Stallion placed the head of his rejuvenated member at her opening. "You ready for this?" He said.

"I want your hard horse cock in me right now, Stallion. I want it so bad. Take me like I'm your mare."

Stallion snorted in compliance and shoved his dick in her as far as it would go. He got six inches the first thrust and inched more and more as she accommodated him. Soon she was taking a foot of horse dick and loving every inch of it.

She moaned, whined, and screamed as her pleasure rose to new heights. Never before had she felt so full. Never before had she felt so good. Never again would she play the prude. She was a size queen from here on out. Stallion was hers now.

Suddenly, Stallion grew in girth and she screamed as it stretched her pussy walls. There was still pleasure, but there was also a twinge of pain. Somehow, that seemed to intensify the pleasure. She came seconds before Stallion released his seed into her womb.

Stallion's dick slipped from her pussy like a wet noodle and dangled between his legs.

If it weren't for the wall, Loni would have fallen face first into the dirt; instead, she passed out in the 'fuck me' position against the back of the house. Terri left her there and led Stallion into the house and up the stairs. The girls seemed to be having a great time as their pleasure resounded through the closed bedroom door.

She opened the door and smiled at the sight before her: Brittany was riding a cock while pawing off a male to her right and sucking a red bone to her left. Ginger was hard to spot at first with the three men covering her; she was on her back with a cock in her pussy, a cock sliding through her cleavage, and a cock in her mouth.

She sighed. She didn't want to disturb their fun. Yet, she was the birthday girl. She wanted to warm up with the doggy dicks before taking Stallion, but if they didn't finish soon, she would have no choice.

The male who Brittany was riding was nearing climax. His knot slipped into her pussy and her bouncing halted. She grinded at his pelvis, groaning. He shot his load into her snatch and his dick plopped out a moment later. Brittany was done. The two other males grabbed their pricks, pawed themselves off, and shot their wad over Brittany's face.

"Come here boys," Terri said. "Time for the main course."

The three wolfs advanced. Terri lay down and one male got to work on her itching snatch. One of the males stood over her and she rubbed at his sheath, trying to coax the dick out for the third time tonight. The third male sucked at her pert nipples while rubbing at his sheath.

The males busy with Ginger realized their master was present and stopped. Ginger moaned in frustration. One male stayed behind to finish her off and started lapping furiously at her clit. Ginger lost it. As she lay convulsing on the carpeting, the last of the six wolf-men joined Terri.

"Alright boys, I'm ready for you. One at a time. Fuck me until you cum, and then step aside. Stallion, you're last. Got it?"

They nodded.

Male number one only had half a fuck with Ginger so he didn't last long. Just as Terri began to feel the pleasure, he came and stepped off.

Male number two lasted a little longer. He stuffed his eight-inch poker in her pussy,

fucked her hard and fast. Terri came during this encounter and was pleased.

The third male had come three times already and fucked Terri for nearly ten minutes. Terri screamed and came countless times before he finished. They ended up tied for a couple of minutes as the shockwaves pulsed through her.

She was now ready for something bigger, but not quite ready for Stallion. She asked two of the remaining males to fuck her. One aimed for her pussy while the other went to her ass. She shook her head and said, "I want you both in my pussy."

The males looked at each other, and then repositioned to get both dicks in her pussy. She nicely lubricated from her last session and they slipped in. The males started fucking her at different speeds and she fell into a constant state of euphoria. The orgasms blended and became one. They came, filling her as she'd never been filled before. Spooge oozed from her pussy walls and the two males pulled their cocks out and stepped off.

"Stallion, I want you in my pussy."

Stallion nodded his dick becoming full hard in seconds and disappeared into her depths. She creamed instantly. "I w-w-want-t-t y-you in m-my a-s-ss," she said pointing at the last remaining male. Stallion pulled out so the wolf could get under her and get his dick in, then he proceeded to fuck her missionary-style.

"Ohhhh fuckkkkkk!!!" She screamed as she was reamed from both ends. There was pain, but there was also immense pleasure. The combination resulted in a sensation that rendered her speechless. All that would come from her mouth were mutterings and moaning. All gibberish.

"I'm going to cum," Stallion said.

"Pull out Stallion," Terri managed. "I want your seed all over me."

Stallion drew out his massive member and stroked it until it erupted hot, sticky, cum all over her. The male under her pumped his seed in her ass and she didn't even notice. He body shut down, convulsing from aftershocks of pure pleasure. The wolf beneath her slipped his cock out of her gaping asshole and rolled her off of him.

They drew her up to the bathroom, stood with her in the shower as they washed the spooge from her matted fur, dressed her in night garments, and took her to her bed. She never roused during any of this, but Stallion wasn't worried. Terri was his master. He would do anything to please her. He gave her a peck on her forehead, she body reforming into that of a man as he leaned over. She slowly reverted to her human form as the night went on. Stallion never left her side.

Four girls, who now share a common gift, slept, completely satisfied, by their new lovers, and the house was quiet again.

The End...
