JoshParkside can take a pounding and a huge cock. I used a Chad Hunt dildo on him once and he took a good deal of it. He's not quite as buff as he looks in his pics. At least a year ago he wasn't. I think he's into PNP (I'm not so it kind of turns me off as he once was a bit "high").
And I think Clark is mainly a top. F-cking THICK piece of meat. Not incredibly long, but INCREDIBLY thick.
