Experience bottoms are hot. Looser holes are hot. Personally I don't get off on seeing a bottom in pain trying to take my dick, or possibly bleeding from being penetrated. I want my bottom to enjoy the experience with me. Sliding into a week fucked hole is a great sensation. Especially fucking them after they been fisted. Furthermore, juste because your loose doesn't mean you have no muscle control. Alot of experienced bottoms make make their holes tighter or looser on command.
