After realizing your wifes friend doesnt have any money to pay you for helping you move, she begs you to stay and let you think of something you might want as payment. She bends over and thats when you realize - you want to smell your wifes bestfriends sweaty crotch. Its so sweaty theres a little wetspot in her buttcrack even. Soon youre nose deep in her yoga pants, burying it deeper into her butthole and she starts touching herself saying "Oh god, this is so wrong, im your wifes friend! She cant find out about this!" You tell her to take off her pants and then your licking her sweaty smelly butt and pussy through her wet panties while she rubs her clit. Then, she starts digging her fingers deep into her tight little butthole then lifting them to her nose and taking a DEEP sniff, and giving them a lick. "Mmmm, is this the smell you love so much?" She digs them in her butt again, them reaches her fingers out to you saying "here, taste!". At first she says you cant fuck, shes not on birthcontrol, but once you start licking again, shes lost and begging for your dick. She cums while riding you, then licks it all off your cock, flips around and rides you reverse, still digging her fingers into her yummy butthole to smell and lick them again. You wife comes looking for you and when she notices your wifes car shes begging for you to cum, even in her, risking pregnancy, saying she doesn't care anymore, she wants your wife to see. Now CUM!
