My sister's friends come to stay in our tiny house. My sister and I share a room... What's more, all of my sister's friends sleep in bad positions, so when I wake up in the middle of the night, I see an incredibly erotic scene in front of me. It's common to see breasts and butts sticking out. It's impossible to not do anything in this situation. But in reality, my sister's friends are the ones who try to seduce me when they're half asleep.
