He unzipped his pants and pulled them down past his cock, which popped out like a spring. He was already hard, so I decided to feel my crotch to see i... I was wet. Indeed, I was.“Please, no.” I was acting my ass off. A random bystander would probably think I was actually being raped.Alex sprung himself onto the bed, on top of me, his cock exposed. He took my face in his hand, squeezing it so I couldn’t talk. “Sshhh...it’ll be over before you know it.” I was ready for him to fuck me. This was. “Do as you are told.”I can’t describe the feeling I had as I read those five words. My heart pounded, my stomach tightened, my mouth went dry. I felt instantly horny. I’d never been so turned on by one simple command. I lay there for a few seconds contemplating saying no, but I was kidding myself. All I wanted in that moment was to please him. I got out of bed, turned on the light and pulled my long, dark hair from the messy bun it was in. Hoping I looked more ‘messy chic’ than ‘dragged through. My mother in law, in her late fifties, is still very attractive looking, is always taking good care on the way she looks. She always has her face nicely made up with foundation, mascara, lipstick and a touch of rouge. She goes to the hairdresser every Wednesday to have her rather bouffant hairdo taken care of. She has quite a good figure, with a nice chest, a reasonably small waist and a very nice derriere, mainly because she always wears kind of old fashioned lace up corsets and long line. Every time they made love, it was a process of unintentional discovery.Last night, was the best ever. Every night that week, they'd revisited their little technique. Each time it got a little better. Each time there was something different about it. But every time Karen came, it was the same exquisite climax.A couple of those times Catherine was able to come, too. Normally she didn't get off easily when she was on the bottom, but seeing Karen enjoy herself so much, it didn't matter. But not.
