What should I do if I want to hook up with my step-brother?
Why would you hook up with your step-brother?
I'm curious to know if his cock is bigger than my boyfriend's.
Your step-brother is part of your family so hooking up with him is weird. Put any inappropriate thoughts about him out of your mind.
I'll steal him away from my sister and hook up with him.
It's not appropriate to hookup with your step brother. Doing this will bring unnecessary tension to you and your family.
