I was curious to see how far this couple would go. Sex Judging from his heavy breathing and the way he was thrusting his groin, he was enjoying the hand job she was giving him. I was on a packed train returning home and hadn’t been able to find a seat. He just pulled his boxers and jeans up over his wet cock and the cum from his earlier hand job. I asked what had happened and Sally told us both. I watched in amazement her hand speeded up and his jeans slipped lower on his hips. They both stopped moving and, I guess, enjoyed the post climax feeling before Jack pulled his cock out. I was extremely turned on and having a teenage girl give me a blow job on a busy train pushed me over the edge. The lad had his head buried in the girl’s neck and was moaning quite loudly. It was dark and most of the students were sleeping or at lease dozing and plugged into MP3s. I was now alone with the young couple in the vestibule area and I asked if that was the first time they had done something like that. The lad looked slightly embarrassed but the girl answered straight away.
