I've already told how I came to begin my sexual relationship with my mother-in-law, Doreen, when she was in her mid-sixties: and I've also told how I first got to fuck her. Along the way, I mentioned that she had discovered my fetish for wearing her knickers. This is the story of how that happened, based on her own words, as I heard her tell it to one of her friends, who joins us for a bit of fun now and then ..
I came home a bit earlier than usual from a shopping trip. I'd noticed my son-in-law's car parked nearby. This was no great surprise - he often visited and had his own door key (I'm 66 years old, and you never know when there might be an emergency). When I got indoors, though, there was no sign of him. I thought maybe he was in the bathroom.
I made my way to the bedroom to change into fresh clothes. The door was ajar, and before I got there I sensed motion in the room. Through the crack I saw my son-in-law pumping a huge hard-on in his fist. He was dressed in stockings, suspenders, panties and a slip. I saw immediately that my underwear drawer was open. Everything he was wearing was mine!
I suppose I should have felt invaded, but instead I started to get that tingling in my lower tummy and between my legs. This was one of the sexiest things I'd ever seen. Of course, I'd seen his cock before, and even seen him cum, but this broke a whole bunch of taboos all at once - a man dressed in a woman's (my) underwear; secretly watching a man masturbate; being overpowered by sexual desire for my son-in-law! My juices were really flowing. I needed my son-in-law's cock, and I needed it right there and right then!
I walked into the room. The look on his face was a picture - total embarrassment; total fear of what I might say to him or to my daughter; total confusion as to what to do next. I had no doubt what I wanted to do next. I took hold of his cock and began to nurse it back to its earlier rampant state. He caught on quick, and soon lost his embarrassment as he saw how turned on I was by the situation.
While I encouraged his tool back to health, his hands were soon making their way up my skirt, hoisting it up. I could tell that he appreciated the stockings and suspenders that I was wearing just as much as those he wore himself. Easing my soaking wet gusset aside, he pushed two fingers into my cunt. It felt so good that I almost came straight away. His thumb came to rest gently on my clit as he slowly finger-fucked me. Within a minute my cunt muscles were out of control as I gave in to a huge orgasm.
Now I gave my full attention to his dick. I pushed him back onto the bed and took the bulb of his cock in my mouth. It was slick with pre-cum and tasted salty - delicious! I'd always wanted to give a man a blow job, and this was my first. It was better even than I'd imagined. Through the gusset of the panties he wore I cupped my son-in-law's balls in one hand. My other hand held his dick upright while I sucked, moving my lips and tongue along his length.
I felt his ball sack get tighter and his already hard cock get even harder. It was clear he couldn't hold on for long, and I was soon rewarded with spurt after spurt of his delicious spunk in my mouth. I swallowed every drop and continued to suck until I was sure there was no more to be had.
That was the start of a whole new phase in my relationship with my son-in-law. Now he has free run of my underwear drawer. He even wears my dresses from time to time. It certainly gives a lie to those who think you're past it when you're sixty-something.
... Amen to that, Mum!
