Stepson caught jerking off, guided to fuck

I was in the kitchen washing dishes. this time I had a little more washing up as my stepson was visiting. While I'm fiddling around in the kitchen, I suddenly hear a groan. And when I turn around, I can't believe my eyes. Since my stepson is sitting on the sofa and jerks his cock. But what a tail! I immediately get horny when I see this huge fuck bullet in front of me. I just can't help myself and have to put it in my mouth right away. Since he has never had a girlfriend, I gave him a little guide on how best to make such a cock squirt. Of course, just jerking off is not enough. The cock can only squirt really cool when it gets a wet cunt to fuck. And oops! What a coincidence! Mine was just dripping. I wasn't even sure if this huge part would fit in with me. But I'll find out.
