My wife has recently asked me to do something for her and her mom. My wife's mom Lisa is really hot, a damn fine good looking woman. But unfortunately at her relatively youthful age of forty six, she's "apparently" been told she's only got at the most, six months to live. At the moment she says she's in reasonable health, but tells us/me that will fail. So my wife being the person she is, recently spent a lot of time with her on vacation. After their break, my wife whilst we were fucking in bed asked me something. She asked me if I'd be her mothers lover for as long as she can maintain her health, knowing I have a very high libido. Lisa is divorced and I know from what my wife says, a very sexually needy person.
Five days ago at Lisa's home, my wife went out only for a brief time, but in that time her mom asked me if her daughter had spoken to me. I told her she had, and Lisa asked me if I'd seriously consider her request. As she said it, she reached into my shorts and gripped my rising cock. Smiling at me she asked me to take it out. I did, and then watched my mother in law take my cock into her mouth. She'd been sucking on my cock for about a minute when my wife walked back in. The look on her face was mixed. It was one of lust, surprise, a touch of jealousy and also one of love. But her comment was only support for her mother as she told us both she'd take a walk. Her mom resumed sucking on my dick until I could hold off no more, and came in her mouth. Lisa swallowed me cum and then rose up to kiss me. It was the kiss that to me at least, seemed totally weird. Moments later my wife walked back in again as if she'd not been away at all.
Back at home my wife asked me if her mom was a good cock sucker. I didn't want to lie, but I also didn't want to upset my wife, so I told her she was okay. When in fact Lisa was far far better at giving head than my wife.
My wife has told me she's invited her mom over to stay this week, as she's going out with a female colleague and might stay overnight. Looking directly at me, my wife asked me to let her know what we get up to and how her mom reacts to having sex with me.
I'm definitely up for having sex with Lisa, but found out yesterday, Lisa hasn't been to a hospital recently (In the past six months) and isn't on any medication at all. Plus one of Lisa's work colleagues, someone I've known for a long time, told me she and Lisa have just booked a vacation for this time next year, WHY ?. Now I'm wondering if this all a great big con, to have me fucking my wife's mom. And if it is, and my wife knows about it, why the fuck haven't they just asked me to fuck her without all the side issues. I'm confused, TOTALLY!!!
