Breeding your stepmom for the first time

Your Stepmom is laying on her bed all dressed up in a sexy lingerie outfit and hot red lipstick on as she waits for your Stepdad to return from his business trip. She gives him a call to check in and see about what time he'll be home. Though she receives bad news... Stepad will not be returning home this evening. "I dressed all up for nothing" she says as she lays down under her covers for a rest. A bit later you enter the room noticing that your Stepmom is resting. You accidentally bump the lamp which makes a noise causing Stepmom to roll over. You hold still for a minute, then start noticing her big fine ass sticking out of the covers! Your cock immediately grows hard as you untie your sweat pants, taking them off as you begin to masturbate while looking at your Stepmom's ass. You begin to touch her ass and ass crack with your fingers, then climb up on the bed as you hover over her with your big hard cock in your hand as you stroke it. She turns and notices you!
