Bimbo in the classroom, BBW in the bathroom

Five years into H1W1, one thing is obvious: institutions of higher education aren't what they used to be. Pack a bunch of horny dudes and smart girls (who want to stay that way) together, and the result is an absolute mess.

Stepping into the physics lecture hall, you immediately hear the tell-tale squelches of multiple students getting their dicks sucked. What you don't hear is a lecture, even though you're five minutes late.

The reason for that soon becomes obvious: instead of your professor standing at the podium, a happy-looking jock is gripping it and thrusting his hips. Apparently the prof is **** enough for a dose that she's willing to suck off one of her students during lecture time--

--Or more than one, judging by the lineup that's forming at the front of the room.

"What a slut," you mumble, plopping down into a seat near the back.

"Oh, sure... Blame her," a voice replies. Looking over to your right, you see a disgruntled brunette woman. She's a few years older than you, yet she has one of the tightest bodies you've ever seen: a toned midriff is visible beneath her tied-off white shirt, which struggles to contain a huge pair of unnaturally-round tits. "You're not the one who has to make sacrifices to be here. You've heard her talk about her latest research, right? Do you have any idea how much cum it must take to maintain that kinda IQ?"

"No, but it looks like you do." Grinning like an idiot, you lean over and cop a feel of her fake tits.

"HEY! You little--" She stops herself, then sighs. "...These are for paying customers only," she continues, nodding at your crotch. "I'm finally gonna graduate this year, so help me God."

"Sure, fill your boots..." Pulling out your fat, quickly-hardening member, you slap it against your thigh a few times. "...Slut."

She opens her mouth to chew you out... But ends up diving between your legs and filling it with cock instead.

Looks like we won't be learning anything today, you think, as the young woman redirects her frustrated energy into a nice, vigorous blowjob. Fuck, am I gonna have to get a tutor? Maybe I should get this cocksleeve's number.

An hour later, you're walking over to Biology when you feel the urge to piss. Stepping into a bathroom, you're once again greeted by the happy sounds of copulation... But this time, the grunts and groans of pleasure are a little more familiar.

"Mom? Cassidy?"

Your overweight mother is sprawled on the floor of the men's room, while your brother sits on her face. Leaning forward with both hands on her chest, he's reverse-titfucking her while she laps at his balls and/or ass.

"Ungh... H-hey man," he groans, thrusting happily. There's already a half-dried load on her belly--Or maybe that's just stray icing. An open box of cupcakes sits off to the side, a few of the tasty treats spilling out onto the floor.

"Uh..." After a brief moment of surprise, you shrug and walk over. "...Hey."

Opening your fly, you begin to kneel down between Mom's legs--Only to realize that you don't want to sully your pants on the bathroom floor. Instead you take them off (along with your underwear), hang them over the side of a nearby stall, and squat down over your mother's belly.

"Sorry, but your pussy's not good enough to make me roll around in filth... Y'know, like you," you tease, unsure if she can even hear you with her head trapped beneath your brother's gyrating pelvis. "Good think you're a fat slut as well as a dirty one!"

With that you start humping her huge, soft stomach, sliding your erection into whatever fupa-fold or belly-bulge presents itself. After a few awkward thrusts you grab her breasts for support, and Cassidy lets out a moan as their grip around his own cock grows tighter.

"Mmgh... Gaaay," he says, but there's a smirk on his face: this is hardly the most heteroflexible thing you've done in the name of getting off.

As for Mom, she doesn't seem to have a problem with it either: you sometimes think that she slowly oscillates between states of token resistance and total gullibility... Maybe it has to do with her digestive system (and the sperm therein). But you spent most of Bio getting sucked off by that stuck-up bimbo, so who knows?

In any case, her muffled grunts don't seem too distressed, and her limbs aren't flailing--Except for one arm, which seems to be pawing at the ground nearby. After a moment it finds the overturned box of cupcakes, clumsily snatches one up, and moves it towards her mouth--

"The fuck?" Cassidy flinches as the cupcake smushes against his thigh. "You can't eat while I'm sitting on your face, dumbass!" He punctuates by bouncing up and down a few times, then pulling up to let Mom breathe--Only to dip his already-spit-slick balls into her mouth. "Here, eat deez."

"Mgh... Mgh... Mmmnngh..." Her eyes flutter a little as she slurps on your brother's nuts, searching for either medicine or calories.

"F-fuck, that's a lotta suction--Careful, I'm gonna--Ungh!"

Cassidy reaches a sudden, hands-free orgasm, his upturned cock spurting thick ropes of jizz into the air. They splatter down all over the place as he continues to mindlessly bounce on Mom's face, and you leap back just in time to avoid getting blasted yourself.

Most of his load lands on her stomach, with plenty more coating the floor and his own crotch. That last set of globs soon begins dripping downward, and her slurps only intensify as her son's balls become jizz-flavored. "...Hmmmmnnnnngh..."

"Hey, watch it," you snap, pulling back and surveying the damage. The belly you were just humping is pretty damn sticky now--But those tits are looking a little cleaner.

Rolling your eyes, you adjust position and begin sliding your cock into your mother's breasts from below--Only to butt up against something.

"N-not done yet," Cassidy gasps. With Mom sucking his balls harder than ever, he isn't going soft... And just as you're trying to get your dick between her tits, he's diving right back in as well.

"Too bad! Find another hole," you reply, tightening your hold on her breasts and beginning to thrust.

"You find another hole! I was here first!"

"You already finished. That means it's my turn."

As you squabble, both of you continue thrusting into your mom's huge, sticky, jiggling rack. Your cocks are making some contact, sure, but you aren't about to give up...

...And just as Cassidy seems about to relent, he tries and fails to pull his balls from Mom's mouth. With a groan of pleasure/frustration and a shrug, he sits back down and keeps on titfucking.

"Mm, fuuuck..." You feel your own sack tingling. "Does she need a load? You feed her since I left?"

"--Mgh--"

"Dunno. Probably."

"--Mm-mmgh--"

"She'll be fine."

"--Mmmnnngh--"

You both continue to ignore her feeble attempts to contribute to the conversation, humping wildly while groping whatever un-jizzed curve presents itself.

"I'm g-getting... Close..."

"Me... Too..."

"Ungh... What if... What if we j-just nut... Like this... And let her clean 'em off?"

"Y-yeah, I... I--HnnnNNNGH!" Cassidy throws his head back as he explodes for the second time in five minutes, and you follow only moments after.

Mom's cleavage is instantly filled with hot, wet semen, and the room is filled with the squelch, squelch, squelch of your twin members thrusting violently between her glazed tits.

You've never felt anything quite so disgusting, yet so good: your cock is completely immersed in warm goo, while being buffeted by a tit on either side and a second spurting tip pressing intermittently against your own.

Meanwhile, the two of you grunt profanities, while Mom just grunts.

"--Fucking s-slut--"

"--J-jizzrag--"

"--Mph, mmmgh--"

"WOAH!"

That last shout comes from a boy who just stepped into the washroom, going totally unnoticed in the passion of your simultaneous double orgasm (or maybe even triple, judging by the wetness between Mom's legs). He stares at the perverted scene... Then sidles around the three of you to get to a bathroom stall. "...Uh, don't mind me..."

Panting, you give your brother an awkward glance before struggling to your feet. Cum is flowing from the top and bottom of Mom's rack, splashing all over her neck and belly... And more coats you and Cassidy, too, with thick strings still connecting your dicks to her cleavage (and each other).

"Nice," he grunts, finally pulling his balls from your mom's mouth with a pop. "Here, Mom, take your medicine..."

With that he slides his dripping, white-painted shaft between her lips, filling her mouth with the medicinal jizz-popsicle (and preventing her from getting to the real dose that's oozing off her chest). She sucks happily, drawing more whimpers and groans from your squatting brother.

"Uh, anyway... Hurry up," you say matter-of-factly, heading over to the sink to do some serious washing. "We're gonna be late for Physics."

"Y-yeah... Save me a seat," Cassidy replies with a grin, before throwing up a hand. "We're really helping Mom out this week, huh? High-five!"

"...Sure," you chuckle, slapping his slightly-sticky hand before turning back to the sink. "Try not to let her pass out. I know you can't drag that ass to the lecture hall by yourself."

"Good call!"

After a thorough hand- and crotch-scrubbing, you dry off and put your pants back on. You leave your brother half-feeding, half-facefucking Mom, trying to make it to class on time.
