Amy has just left with my grandchild. Only he's not my biological grandchild as Amy is my step daughter. Amy's mom is what you might call an absent grandmother as she hardly does anything with her grandson, and pretty much leaves me to look after him when we baby sit. You might think that annoys me, but it's the other way around, as the little one always come to me and pretty much dislikes his own grandmother (She shouts at him all the time).
It also means that I get to spend time alone with Amy, as I'm often around at her home on my own. And there's an ulterior motive to that too. Since Amy turned nineteen, she's now twenty two, Amy and I have been having sex.
We first fucked on New years eve, after she'd been out with friend. And discovered me masturbating as my wife, her mother was once again pissed out of her head. I saw in the New Year on my own and decided when my cock began to stir to whack one off. Not thinking Amy was coming home so soon, she caught me mid tug so to speak.
She'd been drinking too, but no where near as much as her mother, so when she stripped off and offered herself to me, I didn't decline as maybe I should have done. Instead I fucked her only feet from where her mother lay passed out. It wasn't a movie style fuck either, as we were both too horny for that. It was a full on hump, with us changing position twice. Finishing with Amy lean't over the arm of the sofa her mother was asleep on, as I unloaded up her juicey wet c**t.
From then on every moment we've had together like today, we've fucked. Today her mom was doing some washing in the basement, the little one was fast asleep, so Amy and I fucked in the bathroom with Amy having me screw her from behind as she held onto the bath. Amy tells me I fuck her much better than her partner, and that I always make her orgasm, which is something her partner hardly ever does.
There is one other major part to this also. The little one is most likely my child. Next week we'll find out for sure when the DNA results come back. If he is, then Amy and I have already decided that we'll be moving out and then living together. It might not be right for my wife and Amy's partner. But it's what's right for Amy, me and hopefully our son.
