You’ve been married to her for 3 years and you still have never seen the look she has in her eyes when she WANTS to suck dick. Your black friend sees that look all the time, though.
Before she banned you totally from sex and locked your dick in a cage - she wouldn’t let you cum without a condom period. Now, your best friend gets to cum wherever he wants to on her. I guess that’s what he gets for being a real man.
