My wife (f32) and I (m33) live in Europe and received this summer an american friend (f38) of her, married, mom of two, for holidays. She stayed at out place and right on the first day after she arrived, I got horny. The friend is giving a milf vibe currently and I've always fantasized about american moms. After the friend arrived, she took a shower and changed, so her and my wife could go for a walk around the city, while I continued to work from home. After they left, I felt the urge of checking out the panties she was using in the flight over. It was not hard to find the used panties and it was not a sexy panties, it was a big, mom style underwear, but after hours of flight and wearing them, the smell felt great, and I'm not even into smelling panties.
But I couldn't control myself and started stroking with the panties and ended up cumming on it, it was great! After it came the doubt, do I try to clean it? Will she notice it? She is a mom, married, religious woman, then how would she react? Would my wife know?
Many doubts, until I decided to just leave it cummed and where they were and went back to work.
9 days later, no signs that she found out, nothing happened, until the next day, her last day visiting us, where I woke up early to work, wife still sleeping and I started preparing breakfast. The friend woke up early and came to the kitchen to grab some water. After she drank her water, she came next to me to look at what I was cooking and she takes out of her shorts' pocket the panties I've cummed on and she puts on my shorts' pocket and says: "you should keep this". Then she takes out of her other shorts' pocket another panties and give it to me and says: "you better be quick and return to me" and she returns to our guest's room.
I then just took my cock out right there in the kitchen and touched myself with her panties, they were clean, not smelly, but still I've cummed quickly and a lot on it. Then I went to her room to return it, and watched her, while wearing a skirt and a top, put on the cummed panties and then she went on with touching her pussy on top of the panties to spread the cum over her pussy, she even got a bit of cum on her fingers, which she licked. She said thanks, and went on with packing and since then has returned to the US and we didn't speak anymore.
I still hold dearly to her used panties and my wife knows nothing.
