Well, there goes down the drain Samuil's boasting about "i'll wait till you come to me and beg me to fuck you. and i might even think about refusing just to see you squirm."
I don't think he meant by that that he will fuck her against her will till she tells him to keep going.
The dev needs a bit more creativity to make a comeback from that.
But i guess the wife will simply forgive Samuil for being a blackmailing asshole that took her by force and promised her he will turn her and her mother-in-law into fuck toys for the entire camp.
No matter how breathtaking the sex might have been, you would still hate the person for everything that happened before.
edit: most likely the dev will take the "i was too drunk to remeber" emergency exit, and the wife will assume her cumfilling was from the MC during the night whily she was drunk asleep, but suddenly feels a growing urge to fuck black cocks.
She will defenetly not become mad and quit her friendship with her bestie when she shows her what really happened that night.
That would be common sense, and we can't have that here.
