plot idea! girl is dating the mc and the standered ntr plot takes place, she does that typical calling the 'beta while getting plowed' thing and describes whats happening, and turns out he knew she was cheating on him, so he decides to fuck her sister and is in the middle of doing so, and starts mocking her and the dude who cucked him, feel free to think of the insults that are thrown lol for you're own laughs.
