Mother in law
I have a major foot fetish. Got drunk at a family get together, and slipped up and mentioned it to my mother in law. Turns out, she was turned on and we get together once a week or so so I can suck her toes.
In the beginning, it was just me worshipping her feet. Then it progressed to me jerking off while I did it. Eventually, she would give me head during or after. MIL doesnt want "s**," but asked me to give her a*** a few times.
