For some reason (I'm guessing popular porn videos lol) this seems to be growing in popularity with younger guys, especially guys in their 20s. I never seek it out or initiate it, but I'll go along with it if they hit me up and ask for it hahah. And guys that are into rp tend to be creative in other ways sexually - or maybe it's that they are more mentally engaged, which always makes things hotter. I did this this week with this 24 year old cute as fuck Asian dude. He was the stoic jock type with some tatts but when we started going at it, he really got into the dad/son RP. Hoping he wants to do it again
