When I was younger I did it with a close friend growing up. I was at a buddy’s house we were probaby 18 and I was sleeping over at his house and we were just hanging out after his parents went to sleep and he just turns on some porn on his computer. We both watched it silently and I noticed he was rubbing his dick through his basketball shorts and I started doing the same. He jokingly said that we should jack off and I said I was down. He was nervous to pull his dick out so I pulled my shorts down and revealed my throbbing boner. I was so horny I was shaking. He said mine was bigger and I told him it didn’t matter so he took his dick out top – it was rock hard. We started to jerk off together and touched each other’s dicks. I came so hard it was unbelievable

Sounds like a good time. I’ve masturbated to porn with a buddy before (+ some extra) but never touched his dick. Unfortunatly the difference in size was reversed from your situation.
