Bathtime (a classic)
"Well now, stop gawking! I'm only sliding off my panties. It's not like you haven't seen it before, although I suppose it has been a long time since you've felt my pussy grabbing your hard prick, my excitement dripping down your shaft... honey, you're wincing in pain! Does the cage portion squeeze your flacid little dick when I get you all aroused?"
"I'm sorry, why don't I take it off for a while... your behavior has been so very good lately. Here..." (click) "that takes care of the lock, and we'll just slide this mean old cage off and then... well, you're hard already! That makes it impossible to get the ring off... I guess it'll have to stay on as a cock-ring... that's going to make you awfully hard and it sure is making your balls swell!"
"Poor hubby! I tried to make it all better for you and now it's straining!"
