One day at lunch all my friends and I were talking and masturbation came up. Well one girl asked a bunch of questions about how guys do it and was amazed. Later that night I get an instant message from her asking more questions. I answered a few and then I told her I could show her if she wanted. A long pause followed it and then finally she asked if I were serious. I said sure and she asked when and were. I told her tomorrow at lunch in the lounge (a room were they keep all the old desks and couches).
We both met there and I took off my pants and showed her my cock. She was interested and asked if she could touch it. I said sure and she started rubbing my shaft and rubbing my balls. After one minute of this she asked me to start. I took out a bottle of lube I had brought from home and started jerking off. After two or three minutes I asked her to strip down. She was shy at first but then agreed. She slowly took off her shirt and bra revealing her b-cup boobs. As I stroked away she pulled down her pants and to my surprise she had on a black thong. She soon discarded this too.
She asked if she could help, and I told her to play with my balls while I stroked my cock. After four minutes of this she brought her hand up on my shaft and jacked away. Let me tell you, for a girl who had never even kissed a guy she could jack-off real good. I leaned back and let her go at it. Two minutes later I was feeling my climax coming and told her it was. She backed off and told me to cum on her chest. I agreed and started stroking my cock again while she sat there when suddenly I shot all over her. My aim was bad and got it in her hair and all over her stomach and breasts.
She asked how girls masturbate but that is another story.
