I have read somewhere long back an interview of Todd saying about Bad boy street that he just turned in the camera and told them to go on and told that he won’t say stop . Which means actors did things at their own idea. But I cannot find that interview on the net any more. When you purchased the dvd , there are sone extras /extended scenes, which looks more like it’s real from Kevin facial expression that he is getting orgasm when he is playing the top also from the hip movements . But I agree that he being the bottom , it was acting as there could be some thing between their genitals. In the extended scenes you can see the old man really enjoying the way he kiss Kevin , suck his nipples , lick his arm pit and play his tongue . Because when Kevin is the top he doesn’t get engaged much with kissing but yann who played the old man kissed Kevin a lot. At the end of the video once the shooting done , we can see Yann again sucking Kevnn nipples for which Kevn passes a smile looks like he doesn’t have any objection. Also if you see the extended scenes Kevn does much in the top of yann so there are more chances for his tool to be harden Kevn acted only on 2 gay movies with the same actors and In an interview he told that he acted in that movie without thinking feels like he regrets in acting on that movies . Once Todd said that he had just put on a socks with rubber band while doing the sex scenes which means his tool under the socks were rubbing inside Yanns ass. So I think Bad boy street’s sex scenes where Kevn was top is a real one. Rest everything including the blow job was just acting
