In a semi drunken state a fortnight ago, my wife asked me if I thought her mother was good looking. When I told her she was, she then asked me if I thought she had a nice body. Not sure of where the conversation was going, I kept my answer conservative telling my wife her mothers figure was similar to hers (Actually my mother in law has a fantastic figure at 47). Her next question totally threw me. She asked me would I fuck her mum as a favour to her.

Leaving the conversation there, not really knowing what to say, we both woke up the next morning horny. Fucking her arsehole from behind after spending a long time licking her pussy and arse, my wife turned her head and said "My mums been wanting you to do this to her for years". I was about to say something when she added "Please will you fuck her for me". Within seconds thinking of fucking my wife's mum, I came up her daughters arsehole.

Sat in the kitchen a little later, my wife said she was serious about what she'd spoken to e about. Al I could think to say was "I'll think about it" When in truth I wanted to say I'd been dying to fuck her since we met. The subject got dropped until two days ago. My mother in law had just been round although I'd missed her getting held up at work. No sooner than I'd sat down, my wife handed me a note from her mother. It reads "Hi **** I know ******* has spoken to you about the possibility of having sex with me. Sorry I missed you as I wanted to ask you myself. It's been a long time since John died (Her husband died two and half years ago) and I've not had a man since. I'd/we'd love you to be my way back into sex. Think on it please ****** x"

My wife said she wrote the note rather than text me, to prove they were both serious and that I wouldn't think someone else had text me instead. As soon as I read it, my wife kissed me and said "Please honey, just think about it". I had already thought about it and believe me I wasn't going to let them both know how much I wanted to fuck my mother in law. As calm and casual in a way as I could, I told my wife I'd have sex with her mum. Over the next half an hour my wife sucked my cock, had me lick her pussy and arse, and then had me fuck her on our kitchen table. With my cum dripping out of her pussy, she text her mother and got an immediate reply.

Next weekend my mother in law will be coming round. My wife has already arranged to go out with some of her friends and I've saved every drop of cum for her mother. I'm not sure how this will all end, or if it will be a one off. what I do know is, I'm going to make damn sure I fuck her as long and as hard as she can handle it. And hopefully it won't just be a single fuck. The text I got this morning from her suggests it won't be just a one off. I certainly hope that's the case.
