I lead my sub into my black lagoon quite literally on a leash. He's a bit hesitant to get in so I force him to play fetch in the slime. He tries to cheat at our game by using his hands, so I forcefully push his head and body into the goo to force him to play properly. After he looses his ball, I punish. I cover his entire body in slime, stomp him into the pool of goo with my boots and straddle him, forcing him under until he can find it again. Once he does I reward him by riding him in the goo. Now covered in mess, I force him to make me even messier by shoving the slime into my corset until it pours out then sitting on his face, forcing him to lick me as the slime from inside my skirt starts to suffocate him. covering myself in the thick gunge and forcing him to eat me out. After I get what I want I allow him to fuck me in the goo.
Disclosure; this is coed with a male heavy start. We both get messy at the 5 min mark.
