You are sitting next to your mom on the sofa watching a film. You are both under a blanket and your dad is in the kitchen cooking dinner. You catch your moms eye and you both know you shouldn't... you CAN'T... but the thrill of being caught by your dad is just too tough to resist. Your mom flashes you her boobs and quickly shows you her panties. Your dad keeps calling through asking questions and making conversation, with no clue his wife is about to get filled by her son. Your mom continues the conversation with your dad as she quietly straddles you and fucks you right there on the sofa. You can both hear dad walking about the kitchen, which means you have so be SO QUICK. Your mom is so turned on that she thinks she'll be too horny through dinner if she doesn't orgasm now, so she rubs her clit as she rides you, and tries to stifle her moans. As your mom announces she is going to cum, she can't hold back from moaning really loud, causing your dad to question the noise coming from the living room. You both dodge the question. Your mom tells you that you can't cum inside of her, because she is wearing a skirt and is worried your cum will drip down her leg and your dad will see, so you'll have to cum in her mouth and she'll swallow it. Just as you are about to cum, your mom jumps off your cock and puts her mouth over it, catching your whole massive load! It is too much for her to swallow, and so some spills out onto your shirt and down her chin, but she isn't quick enough before your dad walks in and asks what the mess around her face is. Your mom says its nothing and wipes it off, and when dad turns his back, she sucks your cum from her finger and smiles at you.
