Her older sister is always wearing a bra. Even though I know I shouldn't look, I can't help but stare at her. "Hey, what were you looking at?" It's dangerous! I accidentally looked too much! I desperately try to cover it up, but my sister sees right through me and says, "Your erection is obvious!" After she leaves, I completely lose to her temptation and end up having a weakness that I can never tell her about. From that day on, I start having days where she secretly makes me cum while she knows she's sleeping next to her. I want to escape from her right now... I want to escape, but I'm frozen by thinking fuckery fellatio where her tongue gets tangled! My rationality collapses with plank riding where she makes her beautiful butt bounce! And she won't let me do raw creampie... "Fuck it! Let me do whatever I want!"
