My first experience with a girl was a strange one. The girl in question was much older than me as she was a sixth former, and I, only newly arrived at secondary school. Her name was Julia and I was aware that I had quite the hots for her. I think she must have had her eye on me too. On the way back from a theatre trip the coach broke down. They sent us another one, which turned up eventually, and by that time we were all very tired as it was past our bedtimes! This new coach did not quite have enough seats though, so some of us little ones had to sit on the laps of the older pupils. Somehow it happened that I found myself sitting on Julia's knee. I was a bit embarrassed to have to be such a child to her, but it was quite exciting and nice too. As no one could really see me sitting there in the darkened coach I relaxed and settled down.
I do not know how it happened but in holding me on her lap, her hand fell, apparently by accident, exactly on my crotch - the touch was electric. With some embarrassment I felt my cock start to move and very quickly it was stiff and strong beneath her hand. Still Julia, who must have felt the movement going on beneath her fingers, did not remove her hand, but rather seemed to press down more. In my boyish ignorance, I imagined she was not aware of what was happening. The motion and vibration from the road caused her hand to rub up and down on my throbbing erection. I was almost beside myself and to conceal my condition I feigned sleep. I let my head fall on her shoulder and neck - she allowed this. Whether she thought I had really fallen asleep I do not know, but it was quite apparent to me that her fingers pressed my hard-on, and I fancied she was measuring its size.
Things continued in this way for a time; her, almost imperceptibly, but quite obviously, holding my willy through my trousers. At last she had quite a tight grasp and the continued vibrations from the coach, brought me up to such a state of arousal that a jolt, repeated two or three times in succession, and each accompanied with a firmer pressure of her fingers, caused me such an excess of excitement that it brought me to the most delicious sensation I had ever had in my life. I came right into my pants beneath her hand. I tried not to make a noise or shudder, I was still hoping she thought I was asleep. I was suddenly scared in case somebody should discover what I had done. But I felt so wonderfully warm and calm now cuddled up to her lovely neck that I soon was fast asleep. I stayed like this until she nudged me gently to rouse me when we arrived back.
