It's not really a Jinx (obviously) that he has but him having sex the night before makes him loosen up and not be so tense so it makes the fight easier right? I've definitely heard of that being a thing before for some people who do stuff like this?
I started reading this one cause it said complete! What do you mean the side stories include the brother and his partner and I'm loving it but now I'm all caught up and have to wait noooo (/TДT)/
Loosing himself up in the shower? Your dumbass definitely doesn't know how to do it. I bet he didn't do any research about this at all. Literally the last time you guys got intimate you got scared and ran away. So yeah he's gotta do everything. (〜 ̄△ ̄)〜
Big bro is in the hospital...
