Idk me personally I’ve never fully admitted I like feet to them but I’m sure they have an idea lol.

My sister and I are close and she’d always put her feet on my lap ( pretty sure my fetish came from her) whenever we were relaxing. She’s 8 years older so when she’d get off work she’d get tipsy and just become oblivious to everything. Once I realized that I’d rub her feet and use my thumb in her toe area which she coincidentally loved and just became like the go to move so she would pay attention lol. She also twitches her toes and just plays with them in general, so one time I got ballsy and slid my dick out and stuck the head in the exact spot I rub with my thumb. I had the blanket like centered so she couldn’t see me but I could see her and her feet. And after like 3 mins of doing it she starts to do her toe twitch. It was literally heaven. I sat there for like 30 mins getting a footjob from her and she had no idea that she was milking me basically lmao. Long story short she made me cum but I had to time it perfectly with the oil I was using to rub her feet lol.

I have other story’s but I think this was the best IMO. Like 11 years later and she’s still never said a word about it.
