Jizzed myself behind her on her motorbike
I had just started a new job and was chatting to one of the office women at lunch time one day about public transport and getting to/from work. It was taking me over an hour to get to and from work on the bus. It turns out the woman rides a motorbike and lives near me so she offered me a lift. I was delighted as the bus was so slow. She arrived at my house the next morning and gave me a spare helmet. I jumped on behind her and held onto her waist. The saddle on her motorbike sloped down towards the tank so fairly soon i found myself sliding forward especially when she braked. It wasnt long until i was pushed tight up against her leather bum. Then i noticed myself get hard and really turned on. The longer i was behind her the more excited i was getting. Then suddenly i could feel the pressure building in my cock and bang....i jizzed myself behind her on the bike. Ive gotten a lift from her for the last two weeks and have cum behind her every time. It certainly makes commuting to and from work very enjoyable!
