Just be proud that your girl is finally getting the cock she deserves. Be proud of the fact that she’s servicing that big black cock. Just focus on work while you know she’s taking it in your bed at home. Accept it.
"I just met your girl after work and took her home. She was a little shy and hesitant at first, but I am teaching her how to suck my cock since a few hours. I'll let her go when I'm empty. You should be thankful that someone finally takes care of her."
It happened again. You finally bring a girl home, and your mom steals her from you. You try to explain that your mom just does it to torment you and she'll drop the girl in a month or two, but mommy dearest is just too good at it
