At the start of February my daughter and son in law stayed over for a few days, partly to see me, but mainly so my son in law could get early starts decorating my lounge (Adams trade). The next morning, my daughter went to work and a little later I went to the shops to get myself and Adam something for lunch. Five minutes down the road I realised I'd forgotten my purse and went back. Opening the front door I heard a lot scuffling about upstairs and then I thought I heard the linen basket close. Shouting up, Adam answered and said he'd just been to the bathroom.

After lunch I noticed a pair of my panties by the side of the linen basket in my room. I knew I'd put them in properly earlier that morning and I also noticed it looked as though they'd been turned inside out and the crotch area was facing up. Not saying a word but definately suspecting Adam of sniffing my panties, I thought I'd find out for sure the next morning.

I made an excuse of having to visit a friend when Adam had started doing some painting, leaving him alone. Earlier when my daughter had left once again for work, I deliberately left a used pair I'd masturbated into the night before, rubbing my creamy pussy juices all over the crotch area, at the top of the stairs. As though I'd dropped them carrying them down to be washed.

I left the house for about ten minutes and snuck back in. There was no mistaking the sound this time. Adam was masturbating and he wasn't being quiet. Peering into the lounge, I could see Adam stroking his large thick cock and at the same time he had my panties to his face and he was sniffing the crotch area. I watched my own daughters husband whack one off to my cum scent laden panties, and I have to admit it turned me on immensley. So much so I very nearly walked in on him as I was touching myself through my panties. I didn't though and satisfied myself with an almighty orgasm stood in my own hallway, as I played with my clit.

They went back home the following evening, but not before I'd left my panties right outside the guest room with a little note for Adam. The note and panties were dropped just before my daughter gave me a lift to work. The note simply said "Enjoy Adam, I came hard in them last night".

With my daughter and Adam visiting again in early March, Adam now knows I know he'd been masturbating using my panties to get off with. He aslo knows I haven't said anything to my daughter. We'll have more than enough time to find out if he's prepared to go any further, because after the last few weeks all I've thought about is taking his big cock deep inside my pussy.
