"I think the bug's eating away at him, myself. He's holding it until the engineers can make it perfect. They had one failure already, you know. What am I saying, of course you know about that, who doesn't, and so they're awfully leery, the bioboys, they don't want another screwup."
Bioboys don't do this. There's too much direct pleasure for them in fucking. They lose touch, at some point, with the person around the cunt or the ass they are in, and they do what they need to do to come.
