Here are a couple stories,
Once in my social class a year ago. This hot girl Jennelle was in my social class. Well she has the biggest tits ever but she never wears shirts with any cleavage. Well one day we were waiting to get out and she was sitting up on a desk and her thong was sticking out. Well my friend went over and yanked it as hard as he could, she seemed to squirm and then go back to rest and she put her hands in her pants and straightened it out. He gave her a wedgie.
I dont know what it did to me but I got so horny. I went to this one washroom at lunch to beat off but there were too many people going in and out. Then I went into the math hall washroom and went at it like never before. I splooged so hard and so much it was all over the stall.
Another time when I was 15 my sister brought her friend to my cabin. I fell asleep on this one couch and I awoke to everyone sleeping but her friend. I looked and she was in a chair rubbing herself with a pillow over her
I sat up and went at it too, when she went fast and came so did I.
I found the best technique for me. I look at porn for 40 minutes or so and m-bate for the longest time, always going to the edge but not over. then I go and brush my teeth or whatever before bed and let myself get soft. Then when I get in bed I go hard at it, when I come it is so intense and so long I have to spray into my boxers or else my covers get too wet.
