Three goddesses and a horny nothing

"Hey, John!" said Britney. "Come on in!"

You walked inside and waved meekly at Ginny and Paula as they waved at you, barely looking up from their textbooks. All three of the girls had replaced their torn tops with new shirts. They looked super hot in t-shirts that were struggling to fit over their massive breasts. Ginny was lying on the bottom bunk bed, Paula was sitting in one of the desk chairs, and Britney quickly sat in the only other chair. You just lowered yourself to the floor in a corner of the small dorm room.

Britney opened up her notebook. "Okay, now that John is here-"

"Finally," interrupted Paula.

"-we can get started. I was thinking we could do a presentation about..."

The girls began discussing different ideas for the presentation. The fact that you hadn't read the chapter or spent any time thinking about the project didn't matter, they quickly forgot about you. They had clearly invited you just because they were required to have a boy in their group.

The longer the session went on, the more obvious is was that they weren't paying attention to you. So you started looking more and more at their incredible bodies. The reason Britney had been your first test subject was because she'd already been pretty cute, and her friends were just as cute. Ginny was curvy and short, although still quite a bit taller than you were now. Paula was tall and athletic. Britney was a nice combination, not quite as tall as Paula, but with enough curves to drive a guy wild. Obviously you stared at their incredible breasts, but your eyes also roamed over the other parts of their bodies as you imagined all the things you wanted to do with them.

You let out a little moan.

All three girls turned towards you.

"Um, are you okay?" asked Ginny in her low, smokey voice.

"I'm fine," you said as you got up and quickly went to the door. "I just need a little water."

"We have some bottled water if you-" said Britney as you ran out of the dorm room.

You walked, almost ran, down the hall, past the water fountain, and into the bathroom. You went into a stall, sat on the toilet, and immediately pulled out your cock. You started jerking as, in your mind, the three girls pulled you onto the lower bunk and started kissing you.

You came immediately. However, by the time you'd gotten some toilet paper and cleaned up the mess, you were thinking about the girls again. This heightened libido that the professor had given you was maddening. You spent a minute trying to breathe deeply and calm down, but then you just started jerking again. In your mind the three girls pulled off their tops and pushed their big boobs into your face from all sides.

The door to your stall swung open and a woman's voice said, "Oh my god, what are you doing in the women's bathroom?!"
