Stepmom Motivation

School sucks when you're 19 and all you want is a day off and some jerking off to porn. My stepmom Kitten's got other plans though. She corners me about my shit grades and the fact that I'm apparently the only guy not getting laid. Instead of busting my balls she makes me a filthy deal: get my grades up and she'll teach me exactly how to fuck. I'm down instantly. She shoves her fat tits in my face first, lets me suck and grope while my cock's already throbbing. Then she fishes it out and goes to town, jerking me while her tongue works the head. My turn to explore. She grabs my hand, rubs her clit with my fingers until she's dripping, then hops on and slides down my cock like she's been waiting for it. Kitten rides hard and fast, grinding until she's shaking all over me. Flip her on her back, legs spread wide, and I pound her stupid while she squeezes her own tits together. The sight of that pushes me over and I paint her pretty face, watching her lick every drop like it's candy.
