[MF] SIL teases me with her sexy panties

This happened a long time ago with my ex-SIL, but I still think about it all the time.

My ex-wife’s sister, Patty, and I always had an unspoken thing between us. I don’t know what it was about her, pheromones maybe, but every time I was around her it was like she just oozed sex out of her pores. There was always this sexual energy/tension between us that neither of us ever directly acknowledged, but it was unmistakable.

One night my ex and Patty went out for a girl’s night. I was enjoying the Friday night to myself, playing CoD and getting drunk. Finally they came home around 2 and were obviously pretty drunk. Patty came in a sat really close next to me and said how much she wished I had gone with them, I would have had so much fun, etc. I loved being close to and smelling her.

Anyway, we all talked for a while and they were both ready to sleep but I’m still having fun gaming. So I tell Patty she can sleep with my wife in our bed and I’ll just pass out on the couch. I gave her some privacy to change into a lot of my wife’s PJs and we all said good night. They headed off to bed and I headed back to the couch to do more battle.

As I sat down on the couch, right on the floor at my feet were a very sexy pair of blue panties. They were skimpy g-string style and where the thong met the waistband was a blue butterfly. My heart pounded as I instantly realized she’d been wearing these all night. My hands shook a little as I picked them up and brought them to my nose…I was instantly hard as I inhaled her sent.

I pulled my pants down to my ankles and began stroking my harder-than-usual cock as I continued to breathe her in. It didn’t take long to reach climax, and when I came I exploded into the crotch of her panties, absolutely filling them with my huge load.

As I sat there basking in the afterglow, I considered what I would do with the evidence. The diminished inhibitions gave me the courage to simply put them into her bag with the rest of her things.

The next morning she came out and coyly asked if she’d left her panties out there. I told her that I’d put them in her bag. She said, “oh sorry you had to see those.” She grabbed her bag and went into the bathroom to change. When she came out, she was wearing the outfit she’d gone out in that night and I realized she was wearing the panties I’d defiled. She looked at me and gave me a knowing smile and said, “thanks.” We both knew what she meant. It made me so hot to know she was wearing underwear soaked in my cum and she *knew it.*

That was just one of a number of similar encounters I had with her. We never had sex or even kissed, but these naughty little flirtations went on for years, and we never spoke of them. I miss her.
