Yes, you’re right on the edge now, aren’t you? One more firm stroke and you’ll shoot out a geyser of cum!
But I’m not through yet. I’m going to keep you on the edge by lightly stroking your cockhead. It feels so good, doesn’t it? But it’s not quite enough to push you over.
How long do you think I could hold you here? Ten seconds? Twenty seconds? Would you be able to stand it for an entire minute?
