One day when I was young my grandma used to call me over I'd lie on the floor as she put her feet on my stomach to keep them warm and she used to tickle me armpit with her bare feet but one Christmas 2 years ago me, grandma, sister, grandad and girlfriend were sitting in the living room when my grandma looked at me and said Sean do you have a foot fetish I said no and I felt my self go bright red so how do I tell her
