Your clothes almost completely discarded, you press onwards, excited and a little scared at what you might find. There was now no avoiding contact with the slimy walls, which rubbed at your bare skin. A chub was growing in your underpants, which was also beginning to be stained by the juices making you wonder why you didn't take them off in the first place. You stop for a moment and peel them off, leaving you completely nude. Your rapidly hardening cock jabs into the plushy flesh, giving off a nice feeling on your balls. You awkwardly walk sideways sidling your way along until you brush up against something.
