181232 - Struggle to hold, sink gets it all

You're just chilling on the toilet taking a nice dump as I desperately knock on the door. You tell me you need some more time, but I absolutely beg you to let me use the toilet. This is a really expensive hotel, we can't afford shitting on the floor here! PLEASE LET ME USE THE TOILET!!!I come into the bathroom. You can't just break off your shit halfway so you tell me I'll be fine holding it. I know I'm not so I beg and plead as I squirm and struggle to keep my butthole shut tight. It's getting more and more difficult and I haven't shit for almost 3 days! I'm absolutely going mad with urgency.The shituation is making me horny and I take off my clothes. I keep squirming, moaning and struggling and am now also touching my pussy. I tell you how wet I am and how deliciously feminine my pussy smells. I try one last time to convince you to let me sit on the toilet, but to no avail...I lift up my leg and hover my ass over the sink. What are you doing!!?? you ask in shock. I moan as my asshole gapes wide to release a MASSIVE clumped hard constipated log right into the sink. OMG it's huge!!! And it smells so strong!I am so horny and I start sniffing my brown creation as I continue masturbating. You discipline me by telling me to sniff deeper and longer. And more! It turns me on so much, I finger myself hard and gag as I take in the deepest whiffs of my massive shit. My arousal builds to the point of a massive explosive orgasm while hovering over my enormous turd. Fuck this is amazing! I love to be dominated and humiliated by you like this. You think I probably learned my lesson, but the contrary is true. ;)
