Rosie Wilde SC4 walks in as I'm about to mount my DMP (Dildo Mounting Platform) for a ride.  She's intrigued by the sexy-looking device and asks me for a demonstration.  I'm only too happy to show Rosie the "in's and out's" of the DMP, lubing up the cock dildo and lowering my pussy onto it until it's buried balls deep inside.  My curvy butt cheeks really wiggle and shake as I move up and down, the dildo dwarfed by my big round ass, hips and thighs.  Rosie gets excited and wants a turn, so I dismount and share with her.  Guiding the dildo into Rosie's juicy pussy, I coach her as she rides it hard and long to orgasm.  Rosie's thick Latina bubble butt looks so hot as she's riding, I can't keep my hands off of it, rubbing and spanking her cheeks and slipping a finger inside the crack to caress her tight little hole.  Rosie sure is a quick study!
