Nearly caught naked with SIL's panties
It started, I guess, when we were staying with my mother-in-law for a visit and my sister-in-law was living there. I walked by the bathroom and the door was partly open, enough that I could see my SIL inside and naked, leaning over the sink. She was moisturising herself after the shower. She's a bit crazy but is -- or was at the time -- a hot brunette. And I could see her tits hanging and reflected in the mirror as well as her smooth, curvy ass sticking out as she bent over.
I was so enthralled by the view, I didn't notice that she could see me in the mirror's reflection. That is, until I looked up and saw her eyes catch mine. I panicked and ducked away.
A day or so later, I was in the bathroom and about to shower. And, remembering the day before, I left the door open a crack. I was naked and could also see a reflection of the hallway in the mirror. Sure enough, a couple minutes later and I saw the pattern of my SIL's dress standing in the shadow of the hall corner. She was very clearly watching me and my dick instantly started to get hard. When I got in the shower, I wanked hard just thinking about it.
The next day, I was home alone and naked for that day's shower. I was hard again, thinking about the two prior incidents, and I decided to be a little more daring. I went into my SIL's room and started looking for some of her panties. I found a pair in a drawer that actually seemed like they'd been worn already. I put it to my nose to smell and breathed in her scent. Then I wrapped them around my cock and started to stroke.
Suddently, I heard my wife call my name. She was outside on the landing, near the bedroom door. She must have just gotten home. I froze and quietly closed the bedroom closet door. My wife came into the room and called my name again, then left and went to another room looking for me. I quickly put the panties back in the drawer and ran back naked to the bathroom, where I jumped into the shower and turned it on.
My wife came in and said, "Wait... how is it you're in here? I was just looking all over for you." I said, oh you must have caught me while I had just gotten in and before I turned on the water. "You didn't hear me calling you?" she said. Sorry, I said, I must not have.
A day later, I had to travel for an overnight business trip so I stole the dirty panties and took them with me. That night I logged into a sexcam site where the woman on the cam told me what to do with the panties. She made me put them on and then take them off like a stripper, then made me smell them and then put them in my mouth while I jerked off. Later, I jerked into them directly.
I jerked off into them once more on the train home (in the bathroom on the train) and then threw them out, but kinda wish I'd kept them.
I love playing with and wearing any panties I can.
