I went to hang out with a guy friend (m18) at his parents house last night. We were just hanging out and watching YouTube videos on their couch. I don't really remember why but I told him that my feet hurt. He offered to rub them so I turned on the couch so he could. He gave a pretty good rub to my left foot and set it down on his lap and started rubbing the right. I could feel him having a chub. I don't think he knew I'd be able to feel it because when I squeezed it with my toes he looked shook. I just laughed and started rubbing it with my foot. He stopped rubbing so I did to and just told him I didn't say to stop. He went back to rubbing my foot and I went back to rubbing his dick with my other foot. I told him he could stop and put both on his bulge and kept rubbing. I think he came because he started getting soft not long after. It was an amusing scene.
