The graduation ceremony itself, beside being the fairly boring rite of passage that it naturally was, also marked the apex of the siblings’ day of suppressed desires and surreptitious pleasures. In the middle of the valedictorian’s speech, while they stood side by side on stage among their classmates in front of an auditorium crowded with parents and relatives, Michelle lightly elbowed Tyler, just enough to call his attention and have him lean closer to her. As his sister whispered into his ear in a giggly tone that she had just rubbed one off right there with her hand hidden underneath her graduation gown, Tyler let out a grudging sigh and stared straight ahead, his jaw tightening and his imprisoned horsecock rearing to burst out of his pants. Only meeting the proud yet moved gaze of their beaming mother managed to distract Tyler from the insane surge of arousal boiling up inside him, while Michelle’s soft chuckles by his side reminded him that at least she was having some fun.
Eventually, after they received their diplomas, after the collective cheering and friendly hugging and random chatting, after a few uncharacteristic tears shining in Ellie’s eyes as she squeezed them tight to her voluptuous, elegantly dressed frame, after driving back home to spend some more time with their mom before they had to leave for their graduation party, finally Michelle and Tyler were given a chance to let their mutual passion run free. Not trusting themselves to actually manage to keep silent while sneaking an anal quickie even after Ellie retreated into her home office to make some calls and catch up with work stuff, the siblings chose to get changed as fast as possible, rush outside into the balmy evening, jump in the car and drive off. Rather than head straight to Gabby’s party though, Tyler made a strategic detour to a quiet side road just out of town, so that he and Michelle could have some much needed privacy.
Even as Tyler drove, Michelle undid his pants and freed his throbbing monstercock, instantly plunging her face down on his lap as soon as his aching boner sprang out. Mewling wantonly, Michelle was quick to part her hungry lips and wrap them greedily around Tyler’s huge glans, taking his girthy dickmeat deep into her mouth and starting to suck away with gusto. By the time Tyler got to a nice secluded spot and killed the engine, his sister’s head was bobbing furiously on his massive erection, her soft warm lips gliding wetly up and down his pole as a symphony of her sloppy dick-gobbling sounds and his own grunts of pleasure filled the car. Backed up and hyper horny as he was, Tyler couldn’t resist Michelle’s intense, loving blowjob for long, especially not after she shifted into a kneeling position on the passenger’s seat, with her glorious bubble-butt tilted up in the air, wiggling enticingly side to side. As Michelle kept noisily fucking her own mouth on his veiny truncheon with long, vacuuming deep-throat plunges, Tyler possessively grabbed onto her upturned booty and hiked up her ass-hugging mini skirt, revealing her voluptuous buttcheeks in all their plump, naked glory. Groaning and pawing away at his sister’s big meaty globes, Tyler pulled down her thong and began playing with her buttplug, causing Michelle to squeal around his fat sausage as her passionate blowjob got even more deliciously aggressive.
Unavoidably, mere moments after he started to twirl and pump the ass-jamming toy inside Michelle’s lovely little bootyhole, Tyler found himself panting and throwing back his head as his thunderous erection throbbed powerfully, ready to explode inside his sister’s talented mouth. Sinking his fingers into the fleshy plumpness of her big juicy asscheeks, he mumbled deliriously: “Fuck, yeaahh! I’m gonna cum, Mimi, I’m gonna… Cuuuum!”
While Tyler howled in ecstasy, Michelle went from moaning around his cock and sucking him off for all she was worth to holding still with his enormous dong crammed inside her oral cavity, mewling out in indecent delight as the first mighty blast of cum surged into her eager mouth, soon followed by more and more huge geyser-like spurts that quickly inundated her gullet with thick brotherly seed. High on the heady taste of Tyler’s sperm and thrilled by her own cocksucking frenzy, Michelle held Tyler’s erupting schlong lodged deep in her warm, cum-flooded throat while she eagerly swallowed down his torrential load one big creamy gulp at a time, savoring his liquid essence with lewd yet sincere joy. In truth, every dense mouthful Michelle guzzled down made her whole petite curvy frame shiver with pleasure, her pussy copiously dripping with sweet nectar as her horny asshole twitched crazily around the buttplug.
Michelle had barely finished swallowing the final intoxicating blasts of her brother’s tummy-filling ejaculation and thick pearly globs of semen were trickling from the corners of her cum-glossy lips when she suddenly raised her head up from Tyler’s lap and turned up to look him in the eyes. A glinting rope of mixed sperm and spittle connected his still rock-hard pole and her gorgeous mouth while Michelle smiled broadly and hummed in delight, the flavor of her brother’s semen saturating her taste buds and making her head spin with arousal. Her luminous green eyes were alight with desire, matching the flaming buttlust glinting in Tyler’s gaze, as Michelle huskily spoke.
“Oh my god, Ty, I just love drinking your cum! And you came so fucking much, it was awesome! You’ve got to fuck me now, Ty,” Michelle demanded, her words ringing so wantonly urgent that they made Tyler’s unyielding boner flex with increased excitement. “I need you in my ass right now.”
“I’ll fuck your ass alright, Mimi. In a second though. First things first…” Tyler grinned as he easily lifted and turned his voluptuous little sis’s petite form, making her squeak with surprised joy as he maneuvered her on top of him in what was meant to be a sixty-nine position but for the time being only turned her upside down. Reaching between Michelle’s sumptuous asscheeks and slowly sliding the buttplug out of her anus, thus making her purr and bite her lips as she smiled with naughty anticipation over the popping sound of the tapered toy exiting her clingy sphincter, Tyler lustfully instructed: “Sit on my face, Mimi. I haven’t eaten your sweet butthole all day, I feel like I’m in withdrawal or something!”
Giggling and shivering with horniness, utterly unable to turn down an offer to get her ass eaten by her beloved big brother, Michelle removed her panties and settled herself properly on top of Tyler while he reclined his seat all the way back and laid down, so that they were in as comfortable a sixty-nine position as the limited space of the car allowed. Not that comfort was the siblings’ priority at the moment, at all.
The instant Michelle’s magnificent bubble-butt was placed right on his face, with her dripping little pussy glinting with nectar and her irresistible pink bootyhole offered to him oh so invitingly after a whole day of deprivation, Tyler immediately buried his head between his sister’s round bouncy asscheeks and started munching away on her juicy slit and dick-starved anus like his life depended on it. Having been stretched out by the buttplug until moments earlier, Michelle’s adorable winking rosebud remain slightly dilated, making it easy for Tyler to wiggle his tongue all the way into her delicate orifice in one wet butt-probing stroke.
