Biology Class

"Oh shit," Trish breaks the silence suddenly. "We're late for Bio."

You groan. You want nothing more than to stay in bed for the rest of the day, having sex with the three hot teenagers who so clearly want you.

Trish's already slipping her uniform back on, a crisp white Oxford shirt and a classic pleated skirt. She scrambles around the room, throwing books and stationery in her bag.

You slip your pants back on, and hurriedly pull your shirt back over your head.

In your haste, you forget your underwear, which you only realize after sprinting halfway across the campus with Trish.

"It's too late now," she pants, staring at the right flap of your khaki shorts, under which your obscenely large member swings with every step.

Abruptly, she stops.

You realize too late your destination is at hand, and fail to stop in time, crashing into her, your cock pushing into her ass. The touch of her supple bum doesn't help your wardrobe woes.

You walk into class with a semi-erect dick, your mushroom head throbbing an angry red, poking angrily out of your shorts.

Oh shit, you think, as you feel the collective stare of every student in the room. Oohs and ahhs break out from among the pretty schoolgirls.

"That's enough girls," the teacher snaps. She's a tall woman with large tits, her hair tied back into a ponytail.

You gulp as she address you. "You're the new student John, aren't you?"

"Yeah," you say, glancing around the room for an empty seat.

Impressively, your cock hasn't diminished despite the embarrassment. If anything, it's even bigger now, fed off the hungry looks of every girl in the room.

"Hope you didn't have any trouble finding this place," she says, but not sympathetically. "I'm Miss Sweetjuice, and we're studying Human Anatomy and Reproduction today. Since you're late and already in such an awful state of dress, do come to the front, would you dear? You can be our model today."

Despite the way in which her sentences are worded, something about her tone makes it clear that this isn't a request.

You reluctantly step in front of the gaggle of girls, your cheeks starting to redden. Trish has already extricated herself from all this, safe in her seat by the corner.

"Thank you," Miss Sweetjuice says. "Now we need a female volunteer."

Three girls instantly shoot up their hands.

The first is a classic blonde with a cheerleader physique. She fits the bill completely, right down to her blue eyes and large tits. As you catch her gaze, she slowly drops her hand to push those marvelous melons together, winking at you and licking her lips.

The second is a mousy brunette. Her hair is in a disheveled ponytail, and she looks more shy than anything. Her hazel eyes, as brown as her hair, dart from side to side behind her thick black-framed glasses. Nerd, you guess, probably the straight A kind.

The last girl is well, she doesn't fit any bill, at least not immediately. She has Japanese looks, with porcelain features, small breasts, and curly raven hair that hangs below her shoulder. Her lips are plump and rosy, and you can imagine them wrapped around your cock, but she doesn't look like she would be interested. You're not really sure why she volunteered exactly. She doesn't seem as eager as the other two, fiddling with something in her hand instead of looking hopefully at you.

The teacher smiles at you. "Now, I'll give you the choice. Why don't you pick who you want to work with today?"
