As if Sabine would allow that beautiful, fat white cock to be wasted on her halfa daughter's worthless, inexperienced cunt when Adrien could be trained into an ideal blond stud using mature MILF pussy.. Wouldn't want to turn him off of Asian pussy by giving him a substandard chink to fuck.
Such unfathomable tenderness between a bleached mommy and the innocent calf she's raising into a white bull.

Sabine knows better than to risk letting a hung white stud waste himself on the inexperienced likes of her daughter or that uppity brown best friend of hers. Much better to show him the mature chink pussy he truly deserves before he sets about bleaching his friends,, a kindness on her part, really.

Sabine, along with Alya, will make sure Adrien becomes the best stud in Paris and claim every non-white female in the capital for his own (almost) exclusive use and pleasure.
Marinette's too shy and inexperienced to please Adrien anyway, it'd be a waste of the stud's viril spunk and meat.
