While i have never found my MIL particularly attractive, she has a certain sex appeal and i always thought she had a bit of a slutty side. Over the years, i'd had a peek in her bedroom a few times and seen some sexy stuff, toys, leathers etc. she had also shown a flash of stockings and suspenders by mistake at a family party once, which was quite sexy. I'd never been brave enough to do anything other than the mildest flirt, which she'd gone along with but never given any real indication she would take it further.
She is in her 60's now and has a petite but nicely shaped figure, with small tits and a decent ass. Her husband FIL was diagnosed with parkinsons a couple of years ago and while they still get around, their social life is much less than it used to be.
On this particular Saturday, my FIL was going away with his fishing club for their annual event. This was an overnighter in a hotel. My wife had therefore invited her mum and sister to a place near ours for lunch and a few drinks.
MIL lives about 30 mins away, SIL 5 mins away. given she didnt want to stay overnight, i said i didnt mind picking her up and taking her home again so she could drink.
i picked her up without incident. I'm a big fan of nylon and noticed she had a knee length dress on and sheer black nylons underneath (which she often wore). We chatted about nothing in particular until we got to ours, then the girls headed out for lunch. i was having my usual weekend watching sport on tv and never really noticed how long they'd been gone. what i did notice, was how hammered they were when they came back. they'd clearly been through several bottles of wine and decided to make some cocktails at ours to finish the evening. i made myself scarce (their chat wasn't my cup of tea) and said to shout when they were ready for me to take MIL home. A couple of hours later, they were done and were even more hammered. While i was glad they had enjoyed themselves, i was keen to get going. I dropped SIL at hers. she wasn't too bad, but MIL had her eyes closed by the time we got to SIL's house. I assured her I'd make sure her mother was ok and headed on my way.
I assumed MIL was sleeping, but it was raining pretty heavily so i was concentrating on driving in the rain and dark. i didnt really notice her shift, until i felt her hand on my leg near my crotch. i glanced at her and she looked like she was sleeping with her head down, although she was now leaning toward me and clearly reaching over to touch me. I didn't know what to do or say, so just tried to concentrate on the road.
It wasnt long before her hand moved a bit and found where my cock was sitting. Again, i glanced across and she still seemed to be out of it, although her hand was definitely rubbing my dick through my jeans. I could feel it starting to stiffen and had no doubt that she could too. glancing at her nylon clad knees showing below her dress didn't help me avoid getting harder. Especially when she was definitely rubbing the length of my dick through my clothes.
Pretty quickly she moved her hand to my fly and undid the zip, before slipping her hand inside. She found the gap in my boxers and I felt her hand on my now very hard dick.
