So about a week ago, a friend and I went to a party. It was at night and he decided to drive; so on the way there I was really horny and I wanted to jack off. But I really wanted to jack off with him, so while I sat in the passenger seat I cupped my junk and massaged my cock through my jeans assuming he would notice. At one point I saw him glance and then I swear he started massaging his cock; I got way hornier. But then he stopped and carried on with whatever we were talking about. I wanted him to pull it out so bad, but it never happened; I pleasured myself alone there and back just waiting for him to whip it out so we could both jack off.
Being a straight guy, how can I get another straight friend to jack off with me? Or even jack each other off, or maybe even blow each other?
