Sorry for the cross post, but this dude
>>10777137 has a really good point. I can't believe I've never noticed before. It's so obvious. All of the feet, sharkpits, and other fetishes here must have clouded my mind.
Just imagine playing hide and seek with Gura. You take her to a new place every weekend so the unfamiliar surroundings increase her tension. You scare the pants off her and grab her when you find her. She squeals every time and quickly switches to giddy giggling as she playfully tries to get away. You both carry that energy with you, and the second you get someplace private, you jump on her and have wild, animalistic sex. Holy shit, buds. Instant new fetish.
