Stick with me on this.
My step daughter's mother in law and her husband, along with others, were round at my wife's daughters home yesterday for a barbecue. As we were getting ready to leave later on, she cornered me upstairs and began to give me a "Family hug". However the hug changed into her sliding her hands into my shorts and stroking my rising cock. At the same time she turned my head and kissed me hard on the lips. Responding to her, I kissed her back and slipped a hand up her shortish skirt and into her knickers. She was so wet, two of my fingers easily slid inside her. And it was in that position her husband found us. I thought all hell was going to break loose, but instead, he smiled at me and simply entered the toilet. Kissing me again, she slid my dick right out of my shorts and was just about to drop down. That's when her husband walked out of the toilet and said "No time dear, we've got to go". He grinned at me, took her hand and walked them both downstairs.
I was left wondering what the fuck had just happened. Which got even more bizarre today when I got a text of my step daughters father in law, asking me if I'd call by one afternoon this week as his wife would like to "Chat".
Nothing has ever happened like this before, yet I've always kind of known, my step daughters mother in law likes me. Now I'm wondering if her husband is giving me permission to fuck his wife. Because believe me she's one hell of a sexy stunning woman.
