"OK then. Before we carry on, let's make sure you can at least do the other thing I asked for. Fifteen minutes of hard feast stroking, right on the edge of orgasm. No cumming!"
You start jerking off in front of her like a looser. Th edge burns, it feels like forever. Your breath grows heavy, her scent fills your head, nothing exists but her voice and your hand jerking your cock.
"That's it honey, show me how much you want me, need me, love me. Show how you'll go without and torture yourself just to please me."
Oh god, fifteen minutes can't end fast enough.
