I've always wondered what it would be like to be the guy in the middle of a chain like this one.....fucking a guy while getting fucked by another!
It depends. If you're vers, then it's great! If you're a top and really don't like bottoming - or if the guy fucking you is too rough, then concentrating on keeping your erection is a real problem. And timing your motions are a definite issue
So I've heard.
