My sister has butt cheeks so small that when she stands normally, not wearing underwear, you can see her butthole.
She is skinny even at 18. Still lives at home, walked around the house all summer in my old t-shirt and no bra or underwear. I never said anything yet. Been tempted to just nose dive on her when she bends over. I tried to creep shot her, I got caught and she made me promise never again. She doesn't even have any social media, uses her phone for pet pics and texts only.
