# Chapter 7 (Pt.2)

***Bryn/Bryan***

Bryan followed his sister up to the front of class. Her little ass bounced as she did, the little ass he was about to stick his dick in.

He thought back. When he’d gotten to class this morning she was just his sister, annoying, too smart for her own good. Thinking of her as a sex object had been outside comprehension.

But now, her having swallowed his cum, him having brought her to orgasm, even cum up in her soft little pussy. And now for her butt.

She got down into the standard position many of the girls had used, the position that seemed most natural. Hands and knees, ass out, face looking back.

“Be sure and warm her up first Bryan.” Ms. Callahan instructed, noticing in his overeagerness he’d already started to mount her from behind.

‘Right.’ Bryan thought, ‘Warm up, lube first.’ He leaned in and locked his mouth onto his sister’s ass.

“There you go, make sure you get your tongue all the way in your sister’s butt for maximum effect.” Mr. Francis encouraged.

Ms. Callahan gave him a cross look. Sure, he didn’t have to phrase it that way, but he found it kinda kinky.

He pushed his tongue in and Bryn gave out a little sigh of pleasure. He continued to lick his sister’s hot hole as she bobbed back against his face. It was so weird, but so nice, having his face between his sister’s asscheeks, listening to her little squeaks as he made out with her puckered ass.

He gave it one more kiss and then took the bottle of oil, pressed the nozzle directly into Bryn’s asshole, and gave a little squeeze.

Bryn squealed as the cool oil filled her ass, though it was quickly followed by her brother’s fingers. Bryan continued to leisurely slip his finger in and out of his sister’s ass. It moved more easily, now, and he hoped she’d take his cock without too much trouble.

When his sister had sucked his dick he had still been hesitant, even when he went down on her there were still some reservations. But by now he had actually filled her cunt with his cock and sent a second load of cum down her throat. Now the hesitancy had given way to a pure taboo lust for his sister’s body and for her last hole.

The class watched in anticipation as brother and sister made ready to fulfill the final forbidden act.
He finger-fucked her ass a few more times, the shaft of his finger moving fully and completely in and out of her gripping asshole. “How does it feel?”
“It feels kinda weird, but I can feel my pussy getting wet… it feels good.”
When his cock was ready Bryan lifted one leg over his sister and straddled her open thighs just behind her wonderfully round ass. Pushing his cock downward he slipped his cockhead down through the cleft created by the round cheeks of her petite yet cute butt. He centered the tip against the puckered opening of her asshole and pushed forward.
“Just relax and enjoy the feeling, you and your brother will both enjoy it more that way.” Ms. Callahan said reassuringly. “You’ll like it. Just relax. There… that’s better.”
The constant pressure of her brother’s cock head began to open her, and he could feel the initial resistance give away. Bryan pressed his hips forward a little harder and, bit by bit,
the tip of his cock pushed past Bryn’s pink little sphincter until the head finally popped through and he entered his sister’s butthole.

He was inside a girl’s anus for the first time, and it was his sister’s no less, the tip of his shaft slowly disappearing into her puckered opening. He paused a minute to let her get used to the sensation.
“I’m going to fuck your ass, now,” he said softly, remembering Ms. Callahan’s earlier instructions about dirty talk. “Do you want me to do it? Do you want your me to fuck your asshole?”
“Yes, fuck me,” she said going with the flow. “Fuck my asshole.”

“That’s right,” Scott said from the class, “Push your cock up your sister’s ass.”

“Yea take your brother’s cock right up that ass.” Brianna echoed.

Mr. Francis shot the two a look that told them to keep quiet. If the siblings wanted to play up the taboo nature that was their call. Still he had to admit it turned him on a fair bit.

Bryan pushed forward with his hips harder, looked down, and watched the erotic sight of his shaft disappearing into her butt, her tight hole stretched around it. It was tighter than her pussy, yet the walls of her smooth, hot asshole seemed to melt around his prick, molding itself around the shape of his cock.

“Mmmm… that feels good… fuck… mmm,” she moaned under him. He could feel her pushing back against the forward movement of his shaft, humping her butt back against his cock as it continued to move into her. She wanted more; she wanted it all.
Bryan pushed deeper, deeper, more and more of his prick pressing into his sister until he was completely, totally buried up her butt, his balls rubbing against her taint.
Again he paused for a minute, enjoying the wonderful and extremely tight, warm suction of Bryn’s asshole on his prick. He still almost couldn’t believe he was on his knees with his cock up the ass of his trim sister, her round behind pressed against his loins as he was firmly imbedded in her asshole. It was the hottest thing he could imagine; well perhaps he could imagine hotter. Having Ms. Callahan beneath her to suck his cock as she had been with Randi and Jason would be hotter, but it was certainly sufficient. He was glad he’d cum once already – he wanted this to last forever.
Bryan began to fuck in and out of her. Gradually he increase the speed and length of his strokes. He didn’t want to go too fast or pull out too far. “God, this feels good,” he groaned.
“You’re so tight… so warm… I love fucking your ass Bryn… it feels so good…”

Bryn responded by pushing her behind harder against his moving cock.

“Yea, fuck your sister’s ass.” Bryn echoed from Scott’s earlier encouragement, even catching herself off guard, she didn’t know where the impulse for such words came from, but continued nonetheless “I want my brother’s cum in my ass. Do it Bryan, fuck it, fuck your little sister’s asshole.”

This time Mr. Francis couldn’t object, if they wanted to do dirty talk that was up to them.

“Do it to me. Fuck my ass! Fuck me!” Bryn continued “It feels soooo gooood… my brother’s… cock… up my… ass…” she let out between each thrust.

“Fuck me… fuck me… fuck my… ass…” she kept on “Do you like fucking your sister’s ass, tell me you like fucking your sister’s ass!”
Bryan relented, “I love fucking my sister’s ass… fucking hell yes I do! Take your brother’s dick, take it up that ass!”

He picked up the pace and was thrusting hard and faster into his little sister’s ass. Mr. Francis could tell he wanted to cum badly, but after already orgasming twice today the third time was going to take a while.

Bryan was able to draw his prick almost entirely out of his sister’s juicy ass, leaving just the tip inside, tightly held by the muscles in the opening, before plunging it back in and filling her asshole once again. She took every inch and seemed to want more. In and out his shaft split the smooth, shapely cheeks of her ass.

As her brother pumped into her Bryn slipped a hand underneath herself, plunging her middle finger into her wet slit and began to finger-fuck herself.
“Mmm… oh, yeah.”
Bryn was moaning underneath her brother as she pushed her fingers into the opening of her slit and rubbed over her clitoris. Her butt was making small humping motions on
her hand as his cock continued to penetrate her rear. In and out, up and down the siblings’ bodies moved together in sexual arousal, feeding upon each other’s movements as they built to their climaxes.
With each thrust of his cock into her ass a sharp hiss of breath and deep moan came from his sister’s mouth. She was trying to bite her lower lip to keep from crying out in utter pleasure. The incredible tightness of her asshole was milking his cock and he knew he couldn’t hold back much longer. The feelings were just too intense.
“Oh God Bryn, oh fuck, I’m getting close… you want me… up your… butt?! You want your… brother’s…. cum… up your… ass?!” he huffed as he thrust.
Her head came up and snapped back, shoulders and back arching toward her brother and locking his lips with hers. As she kissed her brother Byrn ground her crotch down hard onto the hand underneath her, pushing the fingers up into her hole. The walls of her asshole seemed to close around her brother’s prick in a tight grasp, milking him. Bryan felt the contraction of his balls as they prepared to shoot off into his sister’s butt.

“Yes! That’s right Bryan… cum in my ass! Cum in your… sister’s asshole! Fill me… with your… cum, I want it!.. All of it!”
Two more full, deep strokes into the young girl’s behind and Bryan hit his limit. The first wave of orgasm hit him. He clenched his teeth, grunted, and pushed deep into her asshole as his cock exploded inside his sister.

“Holy shit.” Brianna said.

“Yea, never thought I’d see a guy creampie his sister’s asshole.” Alan responded.

“Stop it.” said Annalee, still not being able to reckon with this particular taboo.

“You realize your little brother probably dreams about fucking your hot little ass right Annalee… dreams about you coming into his room and riding his pole and swallowing his jizz.” Brianna continued.

Annalee tried to tune them out.

“Hell, you probably want it too. Don’t lie, I can see it.”

“Whatever. You’re demented.” she said defiantly.

Back at the front Bryn was feeling the first powerful spurt of her brother’s cock in her ass, certainly a new experience. She felt the warm flow of his cum jetting deep into her, coating the walls of her asshole. This new taboo sensation sent her into her own climax. Her legs came together tightly, squeezing her hand between them. Bryan could feel the clenching of her butt muscles as all of the muscles in her body tensed in orgasm. She came. Hard.
As the last spurt subsided he sat still, mounted on her behind, his softening dick still firmly held in her butt.

Bryn lay still beneath him, breathing deeply, her head on the floor and eyes closed as she enjoyed the after-glow of her own orgasm.
Bryn slowly came out of her sexual haze. “Mmmm… God, that was great. ” she said, looking up at her brother, who leaned down and kissed her full on the lips, his tongue diving into her mouth and being met by hers, “I love you so much.”

“I love you too sis.”

As the two kissed Ms. Callahan smiled, they had finally enjoyed each other’s bodies as siblings, as friends, and as sex partners without guilt or shame.

With her ass still clenched around his shaft Bryan leaned up into his sister’s ear, “Would you please suck my cock after I take it out of your ass… that would be so hot…” he said hopefully.

“If that’s what you want,” she said with a smile, “I’ll happily suck your cock out of my ass.”

Byrn’s ass finally released her brother’s cock with a slurp as he pulled up and out. She rolled over and straddled his cute little sister’s face. She opened her mouth and lowered his now semi-hard dick down onto her tongue.

She suckled her brother’s cock as he lowered it in and out of her locked lips.

***Stephanie/Scott***

As the siblings made their way back to their seats Scott followed Stephanie’s beautifully bright ass to the front.

‘Can I call her my girlfriend now?’ he thought, ‘About to pound my girlfriend’s ass’ he mused with a smile. ‘I’ve never pounded a girlfriend’s ass. Or any girl’s ass. Damn, this is gonna be hot.’

Rather than positioning herself on the mat the cute redhead bent over the teacher’s desk at the front with her soft, pale little ass sticking out.
Scott moved up behind her and ran his hands around over her perky breasts, brushing across her erect nipples. He ran his hands over her bare shoulders and caressed the skin on her back. Now that she was his girlfriend he wanted to savor it all the more, but then again, he’d be getting this ass regularly now wouldn’t he?

She turned her head back and he kissed her, his cock slowly hardening as it pressed along the crack of her ass. He slid his shaft up and down her asscrack as they kissed, then released and kissed his way down her back, kissed her glowing cheeks, and then spread them to plant a kiss on her bright pink asshole.

She gave a little shutter and he gave her a lick, then another, then began to french kiss his girlfriend’s asshole while she pushed gently back against his face.

Grabbing the oil he swapped his tongue for a finger, pushing it up into her as her pink hole clenched around his knuckle. He stood up as he continued gently fingerfucking her asshole, resuming his kiss as he did so, until he dislodged his finger and pulled his waiting cockhead up into position.

He began to slowly push as Stephanie pushed back against him, and then with a soft burst he was in. He looked down and enjoyed the sight of his cockhead just inside her asshole. He’d done it at last. He’d seen so much porn of guys fucking sweet teen girls in their ass, and now here he was, his new girlfriend’s ass wrapped around his shaft.

He pushed in, slowly, then harder. Pumped her as she bent over the desk, their teachers watching intently from the other side.

“Where’s my dick baby?” he asked as he pushed in.

“It’s in my ass.” she said with a snicker, “Your dick is in my ass!”

She pushed back against him with his thrusts, “Your… dick… is… in… my… assss!” she said as he slammed back into him.

“Fuck yea, take it up the ass baby…” he said as he pumped, “Take this big dick right up your ass.”

“Oh yea, give it to me baby…” she moaned in response, “Give me that big dick right up my little asshole. Fill my asshole with that cum!”

With that he burst, cum flooding Stephanie’s tight ass. She kept pumping back against him as he did, squishing his cum back out onto his own shaft, trickling down his balls.

Having watched so many girls do ass to mouth so far that day Scott decided to go for it. Slipping his shaft out of her ass he spun her around and put his hands on her shoulders to guide her down.

She resisted at first, but then with a little more effort she went down to her knees. He rubbed his wet cock around her face then pressed on her lips. She clearly wasn’t the most keen on sucking a cock that had just cum up her ass but with a little more encouragement she opened and Scott’s cock slipped into her mouth.

He ran his hands through her bright red hair and gently pumped his hips.

‘Such a great girlfriend.’ Scott thought to himself as he felt her tongue rolling around his shaft, cleaning his rod like a good girlfriend.

“So fucking hot…” he said looking down at her. At last he pulled out, helped her up, and the pair shared a kiss before returning to their seats.

***Emma/Philip/Seth***

Without needing to ask permission this time Emma came up followed by Philip and Seth.

Ms. Callahan was quite surprised at the young black girl. She’d always been the nerdy girl in the class, kinda shy and never really dating, but apparently she had her own urges that the class had uncovered.

Still standing her two partners came up on either side of her. Seth was in front and kissed her lips while Philip moved in behind and kissed her neck. She could feel their hard shafts, Seth’s bumping against her crotch and Philip’s running along her crack, pressing up between the length of her asscheeks.

Putting one hand on each of their shoulders she lowered them down till they were on their knees on either side and lifted one leg up over Seth’s arm to open herself up to them.

The two boys dug into her holes with their tongues while she whimpered in pleasure above, until she finally felt oiled fingers begin to press in, up into her little black asshole, and even up through her soft pussylips.

Philip rose first and she leaned back to kiss him once again as she felt him positioning his cock head at her ass. She pushed back, relaxing her anal muscle and letting her weight gently drive his cock past her sphincter. When he finally popped inside she let out a sigh of relief.

With Seth still licking her clit and providing support to keep her from falling over Philip began to thrust up into her tight ebony ass.

Seth watched in envy as his classmates oily white cock thrust up between Emma’s dark asscheeks, her little brown hole clinging tightly to his shaft. And then he rose, one of her legs still in his arm, kissing up her flat stomach, over her dark breasts, to her mouth, his rigid cock erecting itself instinctively against her pussylips…

And then he began to push.

Emma was overwhelmed.

‘Wait… he’s pushing in my pussy… they’re both pushing in me…’ she thought as her mind raced… ‘I can’t believe it… fucking hell…’

Her breath caught as the second dick gradually slipped up through her folds and into her pussy, until soon he too was buried to the hilt.

‘Did they planned this?’ she thought as she marveled at the fullness she felt, impaled on two cocks.

“Oh goddamn…” was all she could say as her weight shifted down and both boys went balls-deep in her holes.

She wrapped her arms and legs around Seth and kissed him as both boys now worked to hold her up, Seth supporting her legs and Philip holding her ass aloft.

Here they began to lift her up and down on their rods, driving their cocks up in unison into her holes while she wriggled and squealed in pleasure.

“Oh my God.” Annalee said as she watched, “I didn’t even realize that was possible… One in each hole… so…” her old self wanted to say ‘dirty’ but her new self finished with “…hot…”

The pair thrust up into the hot ebony teen until their arms tired. They lowered her down, and Philip moved to the mat on this back.

Seth spun Emma’s petite body around and she lowered herself onto Philip’s waiting dick. He slipped into her with ease and she lay across him, her lips locked with his as he reached down and spread her asscheeks for his friend.

Seth pressed his cockhead against the nerdy teen’s butthole and pushed hard, driving in till he was fully embedded. ‘She’s already had one cock in there today, no need to go easy’ Seth reasoned.

“Oh shit yea.” she said heatily, “Slam my wet holes.”

The two boys plunged up into her. One then the other. Pussy. Ass. Pussy. Ass. Then they hit a rhythm and both pushed in at once. She shifted between absolutely full and nearly empty over and over until both pulled out and they flipped her over.

“For those who are curious,” Mr. Francis chimed in, “this is another of the more standard forms of group sex, double penetration. Once again, group sex can be an excellent way to share friendships and strengthen bonds, or to satisfy a polyamorous relationship. If there’s interest we can talk more about that later, but let’s let them get on with it.”

Seth ran his hands over her both as he fucked her pussy. Fondled her breasts, leaned in to kiss her as they pushed into her, cocks rubbing one another through the thin membrane separating her rectum and vagina.

The feeling sent Philip over the edge first, jizzing up the cute teen’s black ass while Seth continued driving into her pussy.

When he finished he pulled out and without missing a beat Seth raised Emma’s petite ass just a little higher and drove down into her ass.

Her rectum milked his cock just as it had done Philip’s until he unloaded as well, a second stream of cum running up to fill her bowels. Halfway through he pulled out and sent the last two shots directly onto her waiting face, a line of cum from her cheek over her glasses onto her forehead.

The two boys sat back now beside one another and Emma crawled over to take their cocks in her mouth, one by one moving between each till she’d found every drop of cum left on them.

***Ms. Callahan/Kevin***

Lastly Kevin came forward, and Ms. Callahan light of the erotic display they’d just seen between Philip, Seth, and Emma, she felt she owed him a little something special.

“So, it wasn’t in the syllabus for the class,” Ms. Callahan began, “but since there’s clearly enough interest I think we can use this opportunity to transition into a discussion of group sex… Can we fit that block of instruction in Mr. Francis?”

“Uhhhmmm, sure, why not?!” he said, “It is afterall a situation which some of you girls may find yourself in the future.”

“Indeed.” Ms. Callahan continued, “And don’t worry Kevin, I’m not gonna pass up my chance to have you fill my butt with that lovely cock of yours.” she added with a wink, “You’ll get your practice reaming my asshole shortly…”
