Cousin And My Feet

So me and my two male cousins used to go to my grandmas on weekends together to help out on her farm and have fun. The room the three of us shared had a bunk bed. Me (11) and the oldest (13) cousin (let’s call him J) shared the bottom bunk and the youngest (10) had the top bunk. One time, while we were all in the room watching each other on the PlayStation, J randomly grabbed my foot. I’m extremely ticklish, so I was worried he was gonna start tickling me. That’s when he started licking the sole of my foot. It tickled like hell but I didn’t stop him. I did squirm a lot, but he seemed way too interested in licking and then sucking my toes... eventually, it stopped tickling as much, and he continued for a while between telling me how good it tasted?? My grandma walked in at one point and she was very very confused. This is probably part of the reason why she told me I should have my own room away from the boys. I never brought it up, but a little while ago it popped back into my head and made a lot more sense now that I’m older. I didn’t learn sxEd until I was 16, so this went right uber my head for a very long time.
