When my husband worked away last week, I was left on my own except for Jack my nineteen year old step son, but he'd gone out with his friends.
Around one in the morning I heard Jack arrive home, and it sounded like he'd been drinking. Lay there listening to him stumbling about, I decided to get up. Walking downstairs I came across a sight I wasn't expecting. Jack was sat, half lay on the sofa crashed out, and a porn film was showing on the TV. What really caught my attention though, was Jacks cock, which was openly on show as his shorts and boxers were around his ankles.
His cock was fully erect and even from where I stood, I could tell it was much larger than his father's. Instead of turning around and going back to bed. I walked over, and this is genuine, to cover him up. But the closer I got, the more I couldn't stop looking at his delicious looking hard on.
Then without thinking, I squatted down next to him, took hold of his cock and slowly began to stroke it, masturbating him him as he slept. But that wasn't enough for me. I'd become incredibly turned on and moved my night shirt up, slid my left hand inside my panties and began to rub my clitty. At the same time, I lowered my head and took my husbands sons cock into my mouth. It felt utterly amazing and so big in my mouth. Sucking in Jack's huge cock head, I gave my step son a long slow blow job.
His cock pulsed in my mouth and with each bob of my head, his dick responded by throbbing harder and harder. The without any notice after about ten or so minutes, his cock erupted in my mouth. Not wanting any to escape to leak onto Jack, I swallowed every single drop.
Releasing his cock, I was desperate to orgasm. So moving his left arm out, I took hold of his hand and guided it along my pussy slit. Using it as a rubbing point, I got two of his fingers jammed on my clit and began to fuck them. It didn't take too long for my orgasm to rise, and I was just in the throws or reaching my climax when I saw his eyes open. Too late, I came all over his fingers and watched his perplexed face smile. Jack didn't say anything, but he did grin a knowing grin at me before he went back into a drunken sleep.
I was up and out early the next morning, so I didn't see Jack when he awoke. However around eleven o'clock that morning I got a text from Jack. It reads "You suck cock so good, love to use my tongue next time and not my fingers". It turns out my step son had been awake all along.
Jack and I haven't said anything directly all this week, as I've tried to avoid him. But two days ago I got another text from him. I've saved this one too, which reads "Dads away next Monday to Wednesday night. How about I join you in your bed".
For some time I didn't reply, but eventually I had to answer fearing he might say something to his dad. I replied "We'll see". He immediately put "I'm gonna fuck your pussy and ass so good".
The crazy thing is, I've been so horny for him to fuck me since I sucked on his cock. And each time I see him now all I want to do is have him fuck my mouth pussy and ass. I know we shouldn't, but I just know I won't be able to resist him next week.
