Insert yourself fully, rubbing your swollen glans around and around my spongy one until you're ready to thrust in even more deeply pushing my flaccid cocklet before you fully into my groin. Then, have your way with my "pussy" until you cumm... again and again.
This is an old picture. Since I can no longer get erect you would probably like you doing that even more now because there would be much more room (5" deep) and I'd not force you out by getting hard. You could use my skin-pussy to your heart's content... and then do it some more!
