Casually Riding My Boyfriend Cowgirl In Front Of Stepmom, He Cums Inside

I'm hanging out with my boyfriend at my stepmom's place. She's in the living room, so I decide to take what I want. I strip down, sit on his lap, and slide his hard cock inside my wet pussy. I start riding him in cowgirl position, bouncing on his shaft right in front of her. She's watching me, fully dressed, while I'm completely naked and impaled on my man's dick. It feels so wrong and so hot. I look at my stepmom's face as I ride faster. She can't look away, and neither can I. My boyfriend grabs my hips and thrusts up into me, moaning that he's about to cum. I keep grinding on him, milking every drop as he unloads deep inside my pussy. When I finally lift off, his thick cum drips out of my creampied hole. I show it to her with a smile, then lick my fingers clean. This taboo fantasy is all about exhibitionism, voyeurism, and raw creampie sex in front of an audience.
