[ADN-341] I Fucked My Wife, Who Hates Me, While Being Obsessed With My Partner In Infidelity. Tsumugi Akari
Guy marries hot girl after only a few months of dating, but their marriage is dead now and she acts completely indifferent to him. They agreed to divorce, but it's difficult because his boss introduced them so it would make the boss look bad. Also, he's struggling with the decision because Akari is totally his type. He hires an investigator who photographs her with her college boyfriend guy at a bar. The husband says he's going on a business trip so Akari invites the boyfriend over. But outside, the husband puts on a mask and goes back to his house as an intruder to r*** Akari. Halfway through, she recognizes him and sneers at his failure even in this. This infuriates him more and he goes even harder on her. (Not clear if she ever let him have sex with her in the normal way.) He takes her again in the shower. In a moment of calm they talk and she says she fell for him initially because he always said how cute she was, but after marriage, he was always working and tired after work and never bought her any gifts other than the wedding ring. The boyfriend arrives and husband ties him up, beats him, pulls his pants down and tells Akari to fuck the boyfriend. She refuses so the husband proceeds to fuck her again hard, asking her which one she likes better. He beats the boyfriend more and forces him to swear he won't see Akari again then lets him go. He takes Akari back to the bedroom and fingers and licks her until she cums and squirts hard. Then he fucks her over and over until she finally hugs him as he creampies her again. Closing shot is two months later, she's pregnant but he's left her with signed divorce papers. (not super clear exactly what he says in ending though)
Anyway, this one fits the genre of this thread pretty well. Personally, I dislike all of Akari Tsumugi's r*** dramas but this one's plot was better since took the power back.
