I don’t get what you mean when you say you don’t know how much longer you can last. You’ll last as long as I like, because your cock is locked away behind those little stainless steel bars and your Prince Albert piercing makes them inescapable. In fact, you don’t think you can last another week? Then I’m keeping you locked up for another two weeks at least, I want to find out what happens.
Now, get between my legs. Unless you want it to be three.
