#170 College Days as a young androgynous male

My fantasy: to be a young male in college, taken advantage of.

POOF!
In a cloud of smoke, a Genie appears in front of me, and intones,
"I am the Genie of Fantasy.  I can not make you rich or famous, but I CAN put you into any fantasy world you wish.  You can stay in the fantasy world as long as you want... you can say the words, "Teenie Genie, take me home" or if you fall asleep, you'll return to this real world, and only one minute in real time will have passed."
I eagerly tell him what I want.
POOF!

I had just turned 18 when I started college, but I could barely pass for 16.  
I was small, androgynous, with virtually no body hair anywhere, and I had a tiny penis.
When I first met my new roommate, he asked, "You old enough to be in college?"
"I'm eighteen," I said, glumly.
He chuckled.
Then came the first time he saw me naked, when he walked in as I had just come back to the room after a shower, and was about to get dressed. 

I saw the phone in his hand as he had taken a picture, maybe two, and he looked at me and laughed and said, "You think you'll EVER get laid once a girl sees THAT?"
Glumly, I said, "I'm kinda doubtful."
He looked at me some more and said, "Turn around, let me see you wiggle your ass."
Reluctantly, I did and 

"That is SO sweet," he said, "Now get on the bed on your hands and knees."

I did, and saw him take another picture, then I watched him undress, as he said, "This is gonna be so much fun," and he got on the bed and 

I grunted and groaned as his thick cock slid in and out of my ass, and I closed my eyes and 

POOF!
I was home.
