Solid Rose, whoever you are:
it should be "who STEALS her daughter's girlfriend"
"cucks daughter's girlfriend" would mean that the daughter was the one stolen

A futa mom constantly stealing her futa daughter back from the latter's revolving door of girlfriends does sound hilarious.

Do futas in this world all let their dicks hang out like cowboys showing off their holsters in the early 1900s to stroke their own egos and measure their killing tools?

What an awful mother.
She should search an weird doctor to give her some drugs to get a bigger cock and then fuck back her girlfriend and then her mother

Ploy twist at the en

At first I wondered why the daughter keeps bringing her girlfriends home, but then I realized it's because she knows she'll get 8,000 yen out of the deal.

The daughter is eventually going to move out and completely cut ties with her mother, who will then act all surprised as if she did so "suddenly and for no reason at all".
