When my boyfriend and I used to make out on the couch (or anywhere else), as long as we were kissing his erection would stick up through his pants,and if we kissed for a while the pre-cum would start to soak through his pants. This would even happen if we were kissing in the car, etc. Sometimes we would walk into a store and he would have this big spot of pre come on the front of his pants, and he would try to cover it up by pulling his shirttail over it. The instant we started to kiss he would get hard. I finally would just pull his pants down if we were in private and rub that soft area right under the head of his penis, and he would let out this enormous load of spunk into my hand-that way he wouldn't be just perpetually hard. Sometimes he would even get hard just holding my hand-he was really sensitive.
