Double incest.


You sluggishly opened the door to your room, only to find your stepdad piledriving his dick inside your squeaking little brother on top of your bed. Both of them gave you a nonchalant look, your stepdad not even stopping his hips from hammering down onto your little brother’s feathery butt as you entered.

“Why are you doing this in my room?!” You sighed, both angry and tired after a long day in college.

“It was ~Mmmhh~ your brother’s idea…” Your stepdad grunted while his big bear nuts slapped onto your brother’s stuck-out tush, his big bearcock really digging deep into your brothers backside.

“Ah~ Ah~ Ah~ S-Sorry, b-big bro! B-but your room h-hAs ThE BeSt BeD!” Your little brother explained from between all his high-pitched squeaks and moaning.

You quietly observed your stepdad’s girthy shaft easily slide in and out of your brother, quickly redirecting your eyes elsewhere as not to get aroused by members of your own family. “Last time I recall mom and dad had a pretty good bed in their room though…”

“Come ~Urgh~ On, son! You know we couldn’t do this in our bedroom! Your mom would find us out in a heartbeat!” Your stepdad grunted, grabbing your brother by the hips and slamming his shaft down hard inside your brother, who squeaked even louder underneath the big ursine.

Despite not wanting to watch the incest unfolding in your own room, your eyes couldn’t help but to be drawn to the two sweaty, panting and moaning males on your bed, your cock already getting hard against your will.

Your brother, sharp as always, immediately noticed your searching gaze and wistful glances, shooting up the cheekiest grin he could muster while getting pounded in the ass by a 15 inch bearcock. “W-what’s the matter? Would y-you l-like to join us?” He smirked and you turned your head away in embarrassment. “It’s ok, I know you want to get fucked by dad’s big cock too…”

You were spared from any further teasing, as your stepdad growled, bearing his teeth and you could hear his thick bear seed flowing inside your brother’s bird-ass. He, in turn grasped your sheets and made an ecstatic face while his own aviansie-dick squirted out a small load of cum down onto the green plumage of his chest. Grunting again, your stepdad quickly pulled his orgasming shaft out, slapping it on top of your little brother, shooting a few ropes of his own onto your brother’s green feathers.

Your brother opened his beak, catching some of your stepdad’s cum into his mouth, while bringing his legs up to rub the massive bear shaft that had been inhabiting his butthole for the last few minutes. “...So… How about it? Wanna join us?” Your little brother asked, again with a cheeky grin on his feathery face, licking away the delicious cum it was covered in.

Already hard and extremely aroused, you still turned your head away from the two and huffed in disapproval of their actions. “You’re no fun…” Your little brother whined like the brat he was, or, more precisely, like what he chose to act like, getting up from the bed along with your stepdad while wiping the spilled cum onto your sheets. “You better clean that!” You snarled at your brother.

“Sure, sure! Come on dad, we can do it downstairs while we wash the sheets!”

With that, the two of them quickly disappeared out the door, leaving you alone in your room, which now reeked of cum. You sighed, putting down your backpack and sitting over to your table while your cock was still erect and throbbing inside your pants. “Fuck!” You groaned, whipping out your dick and starting to masturbate, the lingering smell of your dad and brother’s cum filling your nostrils. ‘Why did mom have to remarry…” You thought while beating your meat.

About 6 months ago, your mom, who had been single for almost 8 years had suddenly decided to marry your, now, stepdad: A big and muscular bear who worked as a security guard at the nightclub she had been hanging out at. He had moved in to your house after they had gotten married, and your maneater/superslut little brother had instantly set his sights on your new dad. Then, about a month after moving in, your brother had finally managed to seduce him and that same week you had caught the two of them having sex in the bathroom while your mom was out of town for a few days. Now wanting to upset your mom, you were yet to tell her anything.

Although, there was another reason for you not to tell her, and that was that you actually yourself thought your stepdad was quite attractive and had developed a bad habit of masturbating with, or while smelling his jockstrap he wore to work. Something about his masculine scent drove your hormones absolutely nuts, and you would easily get hard just by smelling him up close. But still, despite your obvious attraction to him, you were pretty adamant about not going all the way with him, no matter how sexy he was in your opinion.

Exhaling deeply, you shot your load into the white tissue you had in your hand, carefully squeezing out all the cum out of your urethra before discarding the rolled up piece of paper to the bin. You heard the front door open and close, which most likely was your stepdad leaving to work his early-night shift at the club. “Good, maybe now I can get some sleep with the two of them not fucking all over the damn house.” You yawned to yourself, moving over to your bed which still somewhat reeked of cum. ‘On second thought maybe I’ll take a nap in Jamie’s room instead’ You thought and made your way to the next room, which belonged to your brother.

Jamie wasn’t in his room, just as you had expected. The sound of a light drizzle echoed over from downstairs, meaning he was probably in the shower, cleaning himself after all the sex he had had with your stepdad. “Good, that should keep him busy for a while…” You muttered to yourself, knowing well, how your little brother preferred to take his time in the shower. Jumping onto your brother’s bed, you quickly fell asleep.

Later that night, you woke up inside your little brother’s room. You tried to stretch your arms but quickly noticed, you couldn't as they were tied behind your back. You tried moving your legs too, but they had also been tied up with a sturdy rope, leaving you completely helpless and bound on your brother’s bed. There even was a makeshift gag in your mouth, which you quickly, by the smell, deduced to be crafted from your stepdad’s jockstraps.

“Wakey, wakey big bro!” You heard cheerful chirping from behind you.

Craning your neck over to look, you saw your brother, naked and grinning at your tied-up appearance. Then it struck you, that you were also buck-naked on the bed. You moaned against the jockstrap-gag, the taste of your stepdad’s crotch filling your mouth as you tried to speak.

“Do you like the gag? I made it with your preferences in mind…” Your brother giggled, moving closer to the bed so you could see him better. You moaned again, the smell of your stepdad’s jockstraps already making your head dizzy.

“Just relax brother… The three of us are going to have some fun tonight…” Your brother said, flipping you over to your belly, so that now your butt was stuck up in the air, leaving you in a very vulnerable position.

“You see, in about 10 minutes, dad gets home from work. I have already told him to come up and fuck me before I go to sleep. And since dad has been super horny today, I doubt he will mind if I’m covered by a blanket while he does his business.” Your brother winked, the outline of his plan coming together in your head as well. You gave him a panicked look.

“Trust me, you’ll love it. I know I did when he first fucked my ass with that big cock of his…” Your brother giggled, getting onto the bed with you, gently stroking the back of your head.

Just then, you heard the front door open, and your brother’s eyes lit up. “Looks like he’s early… That usually means he is even hornier than normal.” Your brother smiled, pulling the blanket over the two of you, leaving your naked backside sticking out from under the blanket at the foot of the bed.

Heavy bear-steps approached the room until the door finally flung open, the lights from the hallway forming a big shadow onto the room floor from your dad’s large ursine body. “You still up, Jamie?” He asked, making his way over the foot of the bed, undoubtedly laying his eyes on your stuck-out birdy-butt. “Yeah dad! I was waiting for you to fu- I mean tuck me in…” Your little brother whistled, holding onto your gagged beak to prevent you from making unnecessary sounds. Your crafty little brother also used his legs to shake your lower body a little bit, your stepdad’s paws quickly grasping onto your jiggling behind.

The big and rough bear paws fondled both your cheeks, squeezing and rubbing the thick plumage of your buttocks. He spread your cheeks apart, and you felt a cold breeze on your exposed sphincter. Your stepdad then retracted one of his hands, which was briefly followed by the ominous sound of him unzipping his pants. The stuffy smell from his new jockstrap quickly darted it’s way up your nose, and you could feel yourself getting increasingly aroused.

You stared at your grinning little brother in panic as the monstrous, half-erect bear cock was slapped onto your tailfeathers, your stepdad rubbing his gigantic breeder onto your backside. Although you couldn’t see, the size and the shape of your stepdad’s phallus were vividly ingrained into your mind from all the times you had seen him having sex with Jamie. But still, feeling it now, actually against your body, especially as he was getting ready to penetrate you with it, was really something else.

“You like this Jamie?” Your stepdad groaned, rubbing his large bear cockhead up and down your crease, the very tip brushing against your virgin tailhole. “Mmmhh, yeah dad... “ Jamie said next to you, suddenly using his feet to fondle your erection under the blanket. “We’re enjoying this VERY much…” He continued, clearly enjoying watching your panicked facial expressions. “...But you know… I had something else in mind too…”

“I hear you son…” Your dad chuckled, taking a firm grip on both of your cheeks again. He spread them further apart in a rough manner, taking another look at your twitching entrance. “..Oh yeah… This little birdhole is just begging to get dicked good…” He groaned, pushing one of his thumbs inside your untouched ring. You moaned, and Jamie also chimed in with his own, to make it seem like he was the one doing it.

“Such a tight grip… Your hole is always so greedy for cock, son…” Your stepdad groaned, removing his furry finger from your rectum, and poking your quivering entrance with something completely different. From your panicked expression, Jamie quickly guessed what was happening and chimed in: “Do it daddy! Make a real mess out of my butt!” He smirked at you, continuing to rub your throbbing bird-shaft with his legs.

“Here I… GO!” You heard your dad say, before his entire shaft was violently hammered inside your virgin butt-pipe. You moaned against the jockstrap-gag, ejaculating onto the sheets below as your rear end did not quite handle the abrupt anal stimulation provided by your stepdad and his gargantuan cock. “MMMmhhhh! Just like that daddy! Do me even harder!” Jamie moaned.

Your eyes widened as the girthy shaft moved inside your tight hole, harshly retracting from the strong grip of your cramped insides. Your stepdad groaned, his entire cock momentarily popping out of your butt. “God damn… I swear you get tighter every time I fuck you Jamie…” He said, before clogging up your rear end with the entire length of his cock. Again, you moaned, with Jamie covering it up with a chirp of his own. “Deeper!”

The big and unforgiving bearcock began to slam inside your ass with a steady rhythm, your stepdad working hard to fight the friction of your virgin walls to drive his fuckrod even deeper inside. Soon you could also feel the sensation of his heavy bear testicles lightly tapping against your own, as he started picking up speed with his thrusts. And all the while, Jamie continued smirking at you, and rubbing your cock with his feet.

“Do you like it big bro…” He whispered. “Can you feel how his cock completely fills you up to the brim?”

You had no energy to respond, as your senses were overwhelmed in multiple different ways at the same time. “You just wait until he cums inside…” Jamie finished, his words dripping with lust.

The small bed had now begun to creak and was rocking back and forth thanks your stepdad’s powerful hip-movements. Your cock was once again throbbing and twitching on the verge of climax, the stimulation from both your stepdad and your brother working wonders on your cock and prostate. Meanwhile it felt like your stepdad’s cock was getting even bigger inside you, the sides of his girthy shaft already greatly stretching your inside walls.

“You okay with the usual Jamie?” Your stepdad asked, continuing to pummel his cock right up your boyhole.

“Of course! Go ahead and cum inside! Give me your babies, daddy!” Jamie chirped, grabbing your gag and stuffing it deeper inside your mouth so that your moans of protest could not be properly heard.

Without seeking any further confirmation from your brother, your stepdad started making short, rapid jabs with his cock, his fuzzy bear hips grinding against the plumage of your ass while he got ready to breed your hole. You were also just about to cum, your little brother constantly toying with the tip of your cock with his toes, glazing them with your pre.

A loud roar of a mating male bear echoed throughout your house, as your aching insides finally brought your stepdad to completion. He really put his weight behind his final thrust, burying his thick bear shaft as deep inside your anus as he possibly could. The surge of his hot male juices immediately hit your inside walls, as he began emptying his seminal vesicles inside your accepting butt.

Despite the jockstrap-gag in your mouth, you let out a muffled, but audible moan, which your brother didn’t even try to cover up this time, as he was too incaptivated in stroking your cock with his feet while listening the bear cum flooding inside of your rear. And who were you kidding? Getting fucked by your stepdad felt extremely good, and him cumming inside; even better. It sort of made you wish you had taken up on your little brother’s earlier offers to join the two of them.

In the end, your cock couldn’t take anymore either, and you too ended up spilling your juices, now for the second time. Jamie gasped delightedly a stream of cum erupted out of your tip, splattering down onto the sheets of his bed, some even getting on his feet which were still toying with your member.

It seemed that your dad had recognized your moan from under the blanket, as he hastily threw the blanket aside, uncovering you and Jamie from underneath. He looked at both of you individually, before looking down at his crotch, which was still steadily anchored with yours.

“Surprise!” Jamie said cheerfully, jumping up and giving your stepdad a quick kiss on the cheek.

Your dad looked at him dumbfounded, and then looked back at you, most likely noticing the gag in your mouth.

“What is all this Jamie?” He asked, still not making any effort to pull out of your feathery behind.

“Well… I felt so bad for leaving big bro out from all of our fun all the time, so I thought I’d set you two up... in a way.” Your brother explained, trying his best to look as innocent as possible.

“I see... “ Your father grunted, taking a better look at your tied-up, naked body. “Then what about that?” He continued, pointing at the gag constructed out of his jockstraps in your mouth.

“Oh, that! You see, brother is actually a real, jockstrap-sniffing pervert! He’s been sneaking into the laundry-room in the evenings and masturbating with your jockstraps.” Jamie explained.

“Ohhh….” Your stepdad said, a sly grin creeping up on his face. “So you are a little pervert, just like your brother huh?”

“Hey Jamie! Help me out here a little bit!”

Jamie quickly hurried over to your dad, and helped him pull down his pants along with his freshly-used jockstrap. He then whispered something to Jamie, something you couldn’t quite make out what it was.

Your brother took the jockstrap and walked over to you. He lift up your head and put the jockstrap over your face, covering your entire beak with the cloth smelling like the your dad’s groin, its’ pungent smell immediately flooding your nostrils. You released a muffled moan, as he fastened the strap to your face, by pulling the two elastic bands over, and onto the back of your head, locking the musky piece of underwear over your face. “Enjoy…” He whispered.

“You like daddy’s fresh scent son?” Your stepdad asked mischievously, looking down at your cock, which was still erect, especially now with the addition of the new jockstrap. You moaned something incoherent in response, already succumbing yourself to the intoxicating smell of his bear musk. “That’s alright… I quite like your ass, son…” He continued to talk, once again fondling your green cheeks with his big paws.

The big bear shaft tickled your prostate as your stepdad pulled it outside of your bum. He slapped the cum-glazed fuckstick onto your rump, smearing his seed all over your tailfeathers. “Help me flip this pervert over Jamie!”

Your eyes widened as your dad and little brother turned you over to your back, exposing your naked front for both of them. “Would you look at that…” Your dad chuckled, staring at your erection. “I guess Jamie was right…” He continued, poking your member with his own, both of them twitching as they made contact. “And if he was…” He quickly moved his tip between your bird cheeks. “...You should like this just as much as him…”

A chill ran down your spine, as you felt your stepdad’s big tip on your entrance again, both your ring and insides very vividly remembering the last visit.

"I can't have any perverts living under my roof you know…" Your stepdad said, rubbing his hard tip against your soft ring. "Looks like I'll have to FUCK all that pervertedness out of you son…" He finished, bucking his bear hips towards yours, the pressure from his tip overriding the resistance of your sphincter in a heartbeat.

The gargantuan ursine phallus re-entering your rectal cavity prompted you to moan, as it felt even better now that you were all lubed up on the inside with your stepfather’s cum. The girthy shaft slid inside with ease, roughly re-establishing a close relationship with your prostate. In preparation for the second round, you took a deep breath through your nose, which had you inhaling your father’s sweet scent quite a bit, making you almost painfully aroused and wishing he’d start already.

Suddenly, Jamie, who now looked a bit frustrated jumped up and shared a long french kiss with your stepdad, both of them moaning into each others’ mouths as their tongues wrestled playfully in the tunnel of saliva. “What about me dad?” Jamie asked, breaking off the kiss and shaking his cute tailfeathers at the sizeable bear.

Your stepdad glanced down at you and your erect cock and smirked at Jamie. “The way I see it, there’s a perfectly good cock right there.” He said, pointing to your rock-hard member. “Why don’t you make good use of your brother while I fuck his brains out?”

Without leaving you any time at all to protest and without hesitation, your little brother mounted your cock, his avean insides taking a tight grip of your eager meat.

“Hmph… It’s not as big as dad’s, but I guess it will do… Be gentle with me big bro…” Jamie winked, wiggling his big birdy butt on your cock. That sentence would’ve sounded more natural coming from you to him, since, you knew how rough Jamie liked it, and if it was left up to him, he would get it rough.

But all those thoughts soon cleared from your mind, as your stepdad wind his hips back and slammed his breeding rod all the way up your hole, making you moan against the wet-jockstrap-gag in your mouth. At the same time, Jamie lift his butt up, just high enough to leave the very tip of your cock inside his rump, continuing by slamming it right back onto your lap, almost knocking the wind out of your lungs upon the harsh impact.

“Hey Jamie…” Your stepdad growled, getting into a good rhythm of thrusting his cock up your stretched ass.

“Mmhhh… Y-yeah dad?” Jamie responded, erratically jumping on your cock, his own shaft violently swinging up and down as he did.

“Take... Urgh~ That gag out… of his mouth… I wanna hear this bitch moan as I fuck him.”

In a flash, Jamie leaned in, hastily unfastening the gag from your mouth, allowing you to once again breathe through your mouth properly. That window was left pretty short, for as soon as taking the gag off, your little brother pressed his lips against yours, aggressively shoving his tongue inside your salivating mouth.

You moaned against his kiss, tasting both your little brother and your stepdad for the same time as you two made out while he rode your cock and while your ass was still getting hammered by your bear-stepdad.

“Now ain’t that cute…” You heard your stepdad say, and it almost felt as if he had just gotten even harder inside you.

And that, in turn, suddenly reminded you of your quivering prostate, and your rock-hard shaft that was getting milked by your little brother’s certified sluthole, all the arousal and pleasure rapidly building up inside your loins.

You tried to moan something into your brother’s mouth, but he was too busy to notice, only moving his hips faster and faster as he apparently wasn’t that far off from his own climax. His green-feathered bird rear bounced on your cock, bringing both of you closer and closer to orgasm as your soft, erotic moans echoed in the room. And all the while, your stepdad and his cock were busy pounding on your back door, getting their fill of poultry for the day.

Finally, you couldn’t hold it any longer, and as Jamie finally broke of the kiss, you voiced out a high-pitched squeak, just like your brother when he came from getting fucked by your dad. Jamie soon followed you up with his own bird-call when he felt your cock erupt inside him and the plentiful avean seed filling him up.

You looked down just early enough to receive the generous load from his throbbing member all over your facial plumage and chest. And as always, Jamie came lots, releasing ropes upon ropes of his cum all over your upper body, his body shivering from all the pleasure.

Now all that was left was your dad, who was thrusting inside you at such a pace, that the fireworks were only a matter of time by now. “D-Do it dad! Cum inside big bro!” Jamie cheered him up, panting and sweating in the midst of his climax.

One last time, the heavy bear-nuts slapped onto your green cheeks, as your father’s loud roar echoed throughout the whole house once more, marking his second orgasm for the night.

You moaned, feeling the wave of his cum rushing into your hole, as he clogged your guts with his hot and sticky bear gunk for the second time. Despite having already gone through this once, it almost felt even better this time. There’s quite no feeling like your big bear stepdad cumming inside your ass.

Again, you squeaked loudly, accidentally and unexpectedly cumming again yourself, further adding to the large cum-deposit inside your little brother’s rump. “Mmmhhh…” Jamie moaned, gyrating his hips on your lap and enjoying his second serving of incestuous bird-seed right up the butthole.

However, to your surprise, your stepdad didn’t slow down at all, but continued to plunge his cock into your hole, having already creampied it twice in the last 20 minutes.

“W-wh-... Y-you’re, s-still g-going?” You asked, looking up at your little brother in disbelief.

Jamie pressed a finger onto your lips and shushing you. “You think dad cums only twice? You’ve got lot to learn, brother. But that’s ok, since we have the whole night…”

The three of you spent the rest of the night fucking like animals, your stepdad cumiming inside your ass at least a dozen times, Jamie having his own fun with whatever he could think of with your body; Fucking your mouth, rubbing himself against your chest, or just simply riding you.

By the end of the night, your stepdad wiped his cum-covered cock clean on both of you, zipped up his pants and left the room. “...You boys get some sleep… We’ll continue tomorrow.” He said before closing the door behind him, leaving both you and Jamie, tired and cumsoaked onto the bed. The sweaty and panting Jamie looked at your spent appearance while smirking as usual. “You’re gonna love dad’s morning-wood-fuck…”
