Polygamy documentary ◯ First wife: Shiina Rena (Kirika Yuuri) (26) ≪Rena interview≫ Interview during cowgirl position: "At first it was just me, but then Miwa came and gradually I started accepting it... aahn!" Rena reaches multiple orgasms from intense thrusting in rear cowgirl position, creampie. "It feels so incredibly good like this, I end up forgiving anything..." The wives get along well regardless of order, and this harmony may be largely due to Rena's broad-minded nature. Marital conflicts are resolved through sex—just earlier, when third wife Shuri scolded Kaz for his gambling habit, he had sex with her right in front of all the other wives. Rena laughs it off slightly exasperated, saying, "He always tries to smooth things over with sex right away~" New wife Mayu joins Rena and Miwa for a cheerful foursome! Mayu receives multiple creampie loads. This is the daily life in their household. ≪Secret rendezvous within the home≫ While Rena is cleaning the garden, Kaz arrives and kisses her, then sneaks a blowjob without the other wives noticing, proceeding to quiet, moaning sex on the porch. Rena climaxes again and again, trembling intensely. They sense someone nearby in the next room, but the aroused couple can't stop, continuing in missionary position with creampie. In such a large shared household, these secret moments turned into thrilling sex are perhaps necessary. All gather together for kissing—some wives even kiss and touch each other. "Equality for all" is their motto: each receives face sitting and cunnilingus, and one by one gets fucked and creampie. Rena sweetly pleads, "Kaz-kun, please cum inside me too..." and Kaz responds with a thick, massive cumshot. Kaz jokes around in front of the camera, making each wife spread her legs wide in a playful display. Laughing together, this extraordinary harem orgy comes to a close.
