I'd say no, but don't make him feel all bad about it. If he keeps on with it, tell him to fuck off and that incest is illegal.

If that doesn't stop him tie his ass to a tree and antique him. He'll probably get over it after washing all the flour out of his hair.

Just kidding.


Seriously though, if it's something you don't wanna do, you're not obligated just because he's blood. That should be even more reason for you to just tell him no straight up.

It's cool that you could come to a place called the Large Penis SUPPORT Group and actually get support. People have forgotten that that is the operative word in the title.
