School Coach

Back to my school days when masturbation was a mandatory exercise especially since we were in a public boys school with the girls school across the road. The only time we got together was for sports and social events so there was always an air of excitement and testosterone in the air. We had an away tennis match after school, singles and mixed. After our school won we were in high spirits and boarded the coach back to school. We were all in our sports outfits, boys in shorts and girls in short tennis skirts. As we neared the school we always stood up to barge off the coach as soon as the doors opened, usual teenager behaviour. As we all got up and tussled in the coach, the coach stopped abruptly and we lunged forward slightly. I braced myself on the seats in front of me. I leaned forward into the girl in front of me and felt her firm buttocks press against by groin. That was enough to wake up my cock. To catalyse the sensation the girl behind pushed into me and placed a hand on my waist to brace herself as her ample breasts pressed against by back. This caused me to push further into the girl in front and lodge my semi erect penis snugly between her buttocks. The driver told us to sit down as there was traffic ahead, obviously none sat down and everyone was still edging forward to see the cause of the jam. By now my cock was getting hard and edging further in-between the firm buttocks in front. The girl in front was by now fully aware of my erection. She slowly turned her head to make eye contact. My heart raced, I thought she was going to shout and make a scene, but instead she looked at me, smiled and said "I need to hold onto something hard so I don't fall". I was relieved and I replied "I'm sure I can help with that, but you'll need to work on it". With her buttocks firmly pressed up against my groin she started to wiggle her hips gently side to side. I could feel the inner skin of her ass cheeks rubbing against the side of my rising cock. With only the thin material of my shorts between us every movement from her made my cock harder and harder. As my cock got fully erect there was no way of keeping it down and by it's own accord the head pushed out between my left thigh and shorts leg. The girl gave a little gasp as she felt my cock directly against the flesh of her inner thigh. Slowly she moved her left hand behind her and placed it on the top of my thigh. Her fingers spread open and started traveling up to my shorts and brushed my cock with the back of her hand. This sent tingling sensations through me and I could feel my rod getting fuller. With her wrist now up my shorts leg she turned her hand and gently cupped my balls and started fondling them with her fingers and giving them a gentle squeeze. The coach moved forward a little and she grabbed my balls for support then as the coach jolted to a halt I leaned forward and her hand moved in deeper between my legs so the tip of her middle finger rested on my anus and her palm on my balls. As she moved her finger between my balls and ass the sensation was ecstatic. Then she moved her hand out, I thought that would be it and I would have to hide my erection. Instead she wrapped her fingers around my cock and made a tight grip. She pulled my cock closer to the inside of her thigh. Then she pulled the foreskin back to reveal my head covered in pre-cum. The head of my cock was now resting on the base of her knickers just under her young pussy lips. Her knickers felt damp and she pushed the head in-between her camel toe so each encased pussy lip was rubbing the head of my cock. She started to pump my cock squeezing and releasing the shaft until my head felt swollen, there was no going back now. The coach jolted back and forth as it moved through the traffic. She gripped tighter and started to slide her hand back and forth along my shaft gently wanking it, the head still between her encased pussy lips. I didn't know how long I could hold back. I had a pair of breasts firmly pushed against be back with the hard nipples now rubbing my shoulder blades and a hand wanking my cock. I had no control of the situation both my hands were on either seat for balance. The traffic was clearing and the coach started to approach the school, I had to cum. She could sense my urgency and started to wank me faster, as she did she clenched her buttocks around the head of my cock. The sensation was intense as she moved my cock up and down her wet knickers along the covered opening of her tight vagina. I wasn't going to last, I leaned forward and whispered to her "I'm cuming", she replied "good, I want it all over my knickers". Her pace quickened and she pushed the head deeper against her knickers and pussy lips. I couldn't take it any more I clenched my buttocks and could feel the sperm in my balls revving up to shoot out. I thrust my hips forward and felt the head of my cock push into her pussy, I must have been in there slightly even with knickers on. I felt the cum racing through my shaft against her fingers and the hot thick cum shoot out all over her knickers and inside of her thighs. She squeezed her legs together clenching my cock and carried on squeezing and wanking my twitching cock until every last drop was out, then she let go and kindly rolled my cock back into my shorts. As the coach came to a halt and the doors opened we started to walk out the coach. As she walked forward I saw some drops of cum on the coach floor. Looking up at her ass I could see some cum slowly sliding down the inside of her thigh down to her knee. She looked back at me and smiled, put her hand around the back of her knee to catch the cum then smear it up her leg. As she did this her skirt lifted to reveal her cum drenched knickers which were wedged deep into her vagina and clinging to her young pussy lips. I could feel my cock starting to stir again.
