Living With Brother

So I live with my 48 year old brother. At night though we both hang out in our underwear. He's generally in his briefs and I'm in regular panties. Well.. as a child we used to play and fight rough. I used to kick and knee his nuts just to make him suffer. I loved it. Our parents laughed about it. I let a couple girlfriends kick his balls when we were 15 lol.

Sometimes when he sits or lays down I can see his balls under his undies because they don't cover him as they should. If he pulls them up better then they are covered ok. So I want to start kicking his balls anytime I see they aren't covered. I've seen his balls soooo many times and I know not to go TOO far when I hurt them. I never went too far as a kid either.

But I also have a secret fantasy to watch him jerk off in front of me or let me do it to him. I wonder if I can get away with all of this.
