This one-take VR production explores a consensual cuckolding fantasy built around miru's reluctant participation in a threesome. Shot completely uncut with both handheld first-person and fixed third-person views, it emphasizes exchanged fluids, nipple play, defloration role-play, hard-riding cowgirl action, and the raw physical detail of sex without edits. At her boyfriend's request, miru reluctantly accepts another man's cock but reacts even more intensely than she does with him, arching so hard in orgasm that her body lifts off the bed. Filled with regret, jealousy, and fear of losing her, the boyfriend realizes how deeply he loves her. The couple then reconnect through intensely affectionate sex. The opening sex scene shows the other man's face.
