A girl.

The buzz is the the only thing your hear, that is until the door opens and a very beautiful girl apears. She doesn't quite notice you, until she hears the loud buzz. She looks around for the origin of the sound. Her face when she sees you masturbating is indescribable. Her face when she realizes you have a cock is even more so. "Oh my god! I'm so sorry!" she squeals turning her face, which is now beet red.
You fumble to pull out the vibrator as all of this is happening. Your ass finally releases it and you turn it off. You get up and wobblely walk over to this girl, your legs still tingling. You turn her around and push her out the door.
"We can talk about this later! Just let me-" you shout but are interrupted.
"Finish?" she asks. Your face blushes to match hers.
"No! Get dressed!" you push her into the direction of the kitchen, and shut the door. You return to your bed and mourn the fact you won't be able to finish any time soon. You clean off the vibrator with a tissue from your box. You think back to the girl, who is probably your roommate, as you get dressed.
She had thick-rimmed glasses, which framed he face very nicely. Her long sandy blonde hair was tied up in a pony tail. She seemed to be very uncomfortable with her body, she was dressed in a long sleeved turtle neck and jeans, showing no skin other than her hands and face. But the whole prospect of her not liking her body seems unthinkable. She was curvy in all the right places, except her breasts. They were small, bordering on an A and a B cup. She was still beautiful none the less.
Once you were dressed, you walk out the door and see your new roommate sitting on the counter. You approach her.
"Sorry for... You know. I'm Unique, but everyone calls me Nicky."
"No worries, but short of it is, I am a girl with a penis. Questions?" you say feeling her stare holes into you.
"Oh, Uh, are you... Do you like boys or... Girls?" she asks.
Your taken aback a bit, but what else did you expect? "Oh... Both, I guess."
"Oh."
"Yeah..."
"So..." she starts, "What's it like?"
"What?" again, taken by surprise.
"You know, In general!" she says.
Your baffled. "Um, well, just like it would to be a girl, just more confusing."
"In bed?" she bursts out.
"Oh no, that is more straight forward." you say laughing. Nicky smiles awkwardly. Then silence.
She shatters it with a small four word question, "Can you show me?"
