Basically a dirty old man (genuinely dirty, filthy fat and balding) scoring a hot girl or woman who is disgusted by him at first. Bonus points if he cucks a handsome guy and impregnates his wife. Also no one should be black. She should be indifferent to him or disgusted by him at first. The POV should not be from the old man or the woman’s. Either the author or the cuck husband.
I’ve read most of it in literotica or anything available on asstr.
