Bus Trip Jacking

I was travelling on an overnight bus trip when another young guy sat beside me and struck up a conversation that soon turned to sex, girlfriends, etc. We were relatively undisturbed in the back of the bus. Soon he asked if I was hard and said he had a blanket which he draped over both our laps in the dim light. After I admitted my cock was rising he suggested we jack off together. I had never masturbated someone else but was curious what it would feel like to jack off another guy's cock. We unzipped under the blanket and reached into each other's jeans to feel our stiffening cocks. We then both pulled our penises and balls out of our shorts. His cock must have been at least 7 inches and his balls were also larger than mine. It was exciting stroking each others' erect penises in close quarters with others around, so it didn't take long for my semen to spurt out copiously. He came soon after I did. Fortunately he had tissues handy to mop up our sperm quietly under the covers.
