Having lived abroad for a few years, I got a new job in my wife's hometown. However, as we were still trying to sell our house, I had to leave it to my wife to sort it out and have moved in with my in-laws as my work is just a few minutes away.
I'd been looking forward to moving there thinking of all the opportunities that would be available to investigate some of the mother-in-law's tights and underwear. Unfortunately, in the first few days, I wasn't left alone at all so never got any opportunities. About the fourth or fifth day I was there, I went into the kitchen for some breakfast and saw a pile of dirty washing lying ready to go into the washing machine. I could see a pair of tan tights in the pile which I knew she'd been wearing the day before. As I was in the kitchen alone, I quickly pulled them from the pile, only to find a black g-string still inside them. I quickly stuffed both inside my shorts and returned to my room, bypassing breakfast!!
Back in my room, I took the opportunity to sniff the wonderful scent of her from the tights' and in particular her pussy from her g-string. By this time, my cock was solid and I slipped on her tights, which were a little small, but felt lovely and tight on my cock. I began to stroke myself through them whilst sniffing her g string and it wasn't long till I blew my load in the crotch. Almost late for work by this time, I quickly shoved both items under some clothes I had left on a chair and rushed out to work.
Arriving at the office, I was told that the guy who was to train me that day had called in sick and there wasn't anyone else available so I should take the day off. Not sure what the in-laws were up to that day, I thought there might be an opportunity to raid an underwear drawer so didn't hesitate in getting back.
When I arrived, their car was gone, so assumed they were out - although I didn't know where to or for how long! However, the door wasn't locked so I figured only one of them was away so no opportunity to get up to anything. Going inside, I went straight to my room to change out of my suit.
I walked into the room and couldn't believe my eyes. My mother-in-law was lying on my bed, her skirt up around her waist, knickers, and tights (black) around her ankles whilst she rubbed her clit. At first, she didn't hear me enter so there was a split second whilst I stood there gobsmacked. Then I realised that not only was she on my bed playing with herself but that in her other hand was the pair of tan tights and she was licking and sucking my cum out of the crotch of them whilst she played with herself.
This all happened in a split second as she sensed or heard my presence and turned to look at me. She was mortified and her face went beetroot. She stammered something about coming in for my dirty washing as she tried to hide the tights that were in her hand at the same time as she tried to cover herself with her skirt. But she still had her tights and knickers around her ankles.
Realising I had been caught with her tights I decided to throw caution into the wind (I figured we were maybe quits on the embarrassment level) and asked her if she was enjoying the taste of my cum. She didn't say anything but glanced guiltily in the direction of the now discarded tights. "Don't be embarrassed," I told her. "Here, try the real thing," I unzipped my pants and shoved my quickly hardening cock toward her face. She hesitated for a split second before opening her mouth and wrapping it around my cock.
The feeling was exquisite as she sucked me and I started to fuck her mouth. I leaned over and lifted her skirt again so that I could see her pussy as I continued to fuck her mouth. She was sucking me greedily and in no time at all, I blasted a load of cum into her mouth which she swallowed entirely with only a slight grunt as it hit the back of her throat. As she licked some of the cum off the end of my dick, I thought 'fuck it' I'm not letting this opportunity pass. I pulled away from her and got down between her legs before starting to lick her pussy. I had never seen a woman leak cum like she was, it was fucking amazing. She squirmed a bit as I licked her clit before slipping my tongue inside her and then down further and flicking her asshole before returning to her clit. She was beginning to pant and moan quite a lot and I was getting stiff again. As she still had her tights and knickers around her ankles and that was where my cock was, I put my cock in the crotch of her hose and rubbed myself against them as I licked her.
It was quite obvious she was near to orgasm and her pussy was now soaking. I was in such a state of excitement I was ready to go again. I gave her one last lick before getting up and shoving my cock into her pussy. It was surprisingly tight (I'm not very big, but my cock is thick!) but I slipped straight in and it felt fantastic. For the first time, she objected, saying, "no, you can't do that....." I continued to thrust and told her, "too late!" She gave up very quickly as she was extremely turned on by this point and I continued to fuck her for a few minutes before we both came to the most amazing climax.
I climbed off her and we both lay trying to catch our breath. There was an embarrassed silence as neither of us knew quite what to say.........
After a few moments, she got up and sorted herself out, saying something along the lines of "let's pretend this never happened and never mention it again" she left.
For the next few days, it was a bit awkward and I spent as little time as possible in the house. Then about a week later, I got home from work and it was only my father-in-law that was in. He told me that the mother-in-law had gone out for a "girl's lunch" and hadn't got back yet. He was just heading out the door for the evening and she would be back any time. Left alone in the house for a while, I was tempted to check out her underwear or dirty laundry again, but decided it was too dangerous and settled down to watch some telly.
A little while later, I heard the door opening and my mother-in-law came back in. After pottering around in the kitchen for a while, she came in and sat on the couch. She had made a bit of an effort for her lunch and was dressed in a black blouse and knee-length black skirt with black tights on. She had taken her shoes off and I could see her toes looking sexy through her tights, although I was trying hard not to look. It was also quite obvious that she'd had a few glasses of wine throughout the afternoon. However, she very quickly decided she'd like another and poured herself another glass of wine and offered me a beer, which I accepted. We sat and watched telly for a while and I could sense her looking over at me. I wasn't sure if I was just being paranoid until she came out with - "can I ask you a question?" "Uh oh," I thought, but said, "yeah, sure."
"I've been wondering? When you took my tights, did you just wank into them or did you put them on?"
