custom - step-Mom catches you sniffing her dirty panties. She is shocked and disgusted. You confess you like the smell and the smell of her bum turns you on. step-Mom decides you can sniff her ass for real and gets you to come close and farts occasionally as you sniff. She asks if you are a virgin, and as you have already gone this far that she should be the one to show you what to do, she sucks you off, you fuck her pussy and she lets you fuck her ass, she tastes her ass on your cock ass to mouth and wants your cum in her mouth. Lots of stepMommy step-son dirty talk
