We were both 19. She was my first sexual partner, I was far from her first.
We were both just beginning our freshman year of college and had an orientation class together. After a night of heavy making out and petting (my first time going and receiving past first base) we got closer and eventually began dating.
Kim is a very short, small blonde. She had something like 28A breasts, pale skin and a cute little butt. I am taller, have 'lax flow' brown hair and skinny.
While I wanted to wait longer before having actual sex, Kim and I were very active doing other things. She loved it when I would go down on her or finger her and she would cum so easily. With only a few minutes of teasing her clit and thrusting my fingers against her g-spot she would gush out liquid and moan my name. She loved it when I came on her and she gave the greatest handjobs I've ever received, allowing me to cum on her stomach or her firm little tits.
One night, after much messing around and making out, her roommate came in and we all prepared for bed. After the lights went out, we spooned for a while, but she could not keep her hands off of me. So, after glancing over to see if her roommate was asleep, she turned around and reached down to my rapidly growing penis. Starting by playing with my balls, she worked her hand up around my shaft and began slowly pulling it, growing faster and faster. I leaned my head into her shoulder, trying to stifle my moans as I felt the pleasure flow through my body. After a minute, she switched and moved her hand to the top of my cock head, pulling the foreskin with her fingers while her palm smacked the head.
At this point, I could not repress my moans. Thank god her roommate didn't wake up! Or if she did, she pretended to be asleep.
Kim continued to masturbate me in this way until I could hold back no more. I thrusted into her hand and exploded, my cum gushing out while she tried desperately to catch it all.
While I was always afraid of waking her roommate, we did this almost every night after. She would say goodnight to me and minutes later have me in ecstasy in her hand.
