I wouldn't be down for anything with a woman involved, but there are two bisexual scenes that are among my favorites, for some reason. Both are Corbin Fisher, one's Tom & Kellan - Kellan is fucking the girl while Tom watches, and Tom joins in so Kellan is alternately fucking the girl and Tom's mouth. Once Kellan comes, Tom flips him over on his back and starts fucking him, much to Kellan's surprise. The other is Bryan (Cavallo) and Vince, it ends with Bryan on his back with Vince fucking him; I think the girl is stroking Bryan's cock.
