Two nights ago I blew my twenty year old step son off as he lay crashed out on the living room couch. He'd been out with his mates, and I'd gotten up leaving his dad asleep in bed to get myself a drink. From what it looked like, he'd been masturbating or playing with his cock, as it was out and flopped to one side.
It looked so horny and so big, I couldn't help myself. Dropping to my knees, I took hold of it, popped it in my mouth and began to suck on it. It wasn't too long until it was fully erect and I felt his hands on the back of my head, forcing me to take in more of his beautiful dick. Licking sucking and slurping in his cock, I fully enjoyed every inch of his prick. Playing with my pussy and clit as I sucked in his cock I brought myself to orgasm, just before he unloaded in my mouth. He kept on fucking my face until every single drop had left his balls and I'd swallowed the lot.
Releasing his cock, I lifted my head and smiled at him, he smiled back and said "Been wanting you to do that for two years now". Hearing his dad moving upstairs, we both sorted ourselves out, and I went to get my drink. Stood facing the sink, he walked up behind me, put his hands around my body and felt my bra-less breasts through the cotton robe I had on. Putting his mouth to my ear he whispered moments before his dad walked into the kitchen "Next time I'm going to fuck you".
That next time could be as little as three days away, as his father will be working away for two nights. Now all I have to decide is am I going to cheat on my husband with his son, and allow him to fuck me.
