Step-mom London River gets the time of her life when she catches step-daughter Casey Calvert having phone sex in a room full of dildos and slutty sex toys. Casey is talking slutty on the phone decked out in a super hot cute outfit with a ebony leather corset, see thru net top showing her fine natural tits and thigh high stiletto platform boots when London shows up unexpectedly with a housewarming gift. She can't believe her daughter has stooped so low to be doing this kind of thing for money but Casey is having a great time being a strong pretty independent lady living on her own and now she is going to show her step mom how she's been missing out all these years by making London her Secret Buttslut. Casey props one leg up on the counter and spreads her butt cheeks fat so London can get in there for some introductory butt licking. Then Casey takes her step moms clothes off and reveals London's massive melons and voluptuous bod and fingers her step moms butt, she loves it. Ms Calvert slides the stiff metal dildo into London's behind and mounts her while she vibes her clit with the Hitachi and she cums hard. Now with a monstrous strap on dildo London gets a deep throat fucking to get that schlong all nice and slippery. Casey commands London to flip over with her booty high in the air and Casey rides her juicy butt until it gapes. London has never experienced such things before and she can't get enough of this hot action. On her side with legs spread fat open Casey fucks her butt some more with that wide schlong until London gets off real good. Then London rides Casey's schlong in reverse cowgirl and fucks it hard until she is moaning in pleasure and having lots of orgasms. The fun isn't over yet! There are so many toys to play with and London is excited to try them all and get her butt stretched wider than shes ever known. First Casey stuffs a enormous clear acrylic butt-plug in her stepmom's behind and brings her to an intense cumming while choking her and rubbing her twat. Then finger by finger Casey inserts her whole fist in to London Rivers ass and fist-fucks her until she is screaming in delight. London's booty can take a lot it turns out so next she gets the really long flexible rubber slink stuffed way up her ass until she cant help herself from cumming. Now on all fours Casey inserts a smooth silver ball into London's tight butthole and she blows it right up and then pushes it out. Finally its Casey's turn to get some butt lovin' pleasure from her step daughter. Casey smothers London's face with her curvy ass while London sucks her butthole and tries to breath. And then she mounts Casey's behind with the stiff metal dildo in a few different positions until Casey cums hard. From ass to mouth they both lick the dildo clean knowing they will be Secret Buttsluts forever!
