I loved masturbating as a teen, I was quite surprised to find out my girlfriend did too!
We had been going together for about six months or so and we got along just great. Linda (not her real name) was from a strong Catholic family, so I assumed I was not going to get anywhere too far sexually with her. One summer afternoon we were at her house with her older sister and boyfriend. Her parents had taken her two younger siblings somewhere and they wouldn't be home for a few hours. We were in the living room and her sister and boyfriend were in another room. The sisters had an agreement to stay in different areas of the house to guarantee privacy. Hot Damn!
We were doing the usual kissing and me feeling her breasts under her blouse with bra unhooked. I would kiss those beauties like crazy. This went on for a while and then she starts rubbing my erect penis through my jeans. I was quite startled and very pleased! I never thought she would do that. I then reciprocated by rubbing her crotch on the outside of her shorts. After lots of moaning and groaning from both of us, she unzipped my pants and grabbed by engorged cock and slowly stroked it. I was in heaven! I quickly shoved my hand into her shorts and undies and began to rub her too. I had never had my hand in a girls pussy before so I was fumbling around until I found her clit and she smiled and let out a very satisfying moan. Jackpot!
We then moved off the couch and onto the floor. My jeans were pulled down to my knees and so too, her shorts. Her blouse was all unbuttoned and my shirt as well. We were as close to naked as we felt safe in getting. It didn't take long before I was ready to cum, and cum I did! She slowly kept rubbing my shaft as I finished pumping out my wonderful white load. She cleaned up with a few tissues, and I said now it was her turn. She laid on her back and I kissed her breasts and had my fingers on her clit and rubbed her like crazy. She was moaning, groaning, and thrusting her pelvis heavily. Then her legs stiffened, her breathing was heavy and deep, and then she had one pretty heavy orgasm. I almost came again just watching her enjoy herself.
The rest of that summer we masturbated each other as often as we could. Once in a while we would take chances and she would jerk me off while I drove. Then I would do her while driving with one hand.
I couldn't believe how lucky I was to be doing this at high school age! I never told any of my friends because I knew it would get back to her that I was bragging at school. The few minutes of being able brag versus a constant supply of sexual experiences with a cute blonde teen? Seemed like an easy decision to me. So this was the start of one great summer!
