You come into my room bored, I'm scrolling on my phone. After some annoyance, and you grabbing my phone and bickering, we get onto the subject of cum. I cant believe we're having this conversation, this is so wrong, we're step-family. You are very intrigued by talking about it, and actually turned on, hang on a minute, is your cock actually getting hard, what the fuck. Surprisingly I find this really horny, this could be fun, I encourage you to stroke... and then also eat your cum!
