You're spying on Mommy while she works out in the basement. You love the way her tits bounce in her sports bra while she uses the exercise machine. You think you're being quiet.. but Mommy notices you're down there. Immediately she begins lecturing on you for spying on her yet again. You promise you'll leave, if maybe she would just show you her big soft titties without the sports bra on. At first she says absolutely not but she proposes she'll show you on the one condition that you be a good boy and stop this naughty behavior. She puts them in your face and lets you touch them before quickly putting them away and confessing she's already gone too far. She tells you that your dad hasn't been fucking her and it IS nice to get some attention, even if it's from her own son. So maybe just this time she'll let you put her cock between her tits. You'd like that, wouldn't you? She gets on her knees and wraps her massive tits around your throbbing cock, getting you nice and wet with her spit as she slowly begins to titty fuck you. You want to cum in between those tits so bad but Mommy is horny now, too. She wants to ride you so she can cum, after all you shouldn't be the only one who gets to finish! Mommy bounces on your cock until she has a huge orgasm, and then happily gets on her knees to take your load. She sucks and strokes you until you can't hold back, blowing all over her beautiful face.
