Ai no shinsekai (1994)
One of the girls has her hair in tight braids, sitting behind the guy on a couch, covering his eyes with both hands — it starts off playful, like a flirt game. They’re in what looks like a sunlit living room, blinds halfway down, casual clothes on. Later you see the same two girls at a dimly lit casino table, acting like they’re gambling, but it’s clearly staged — one leans in close, laughing, touching the other’s arm. Cut to a close-up of one girl alone in a hotel room, wearing earrings and a necklace, eyes wide like she’s surprised someone walked in — her expression sells the scene. Eventually it moves back to action with the guy sandwiched between them, taking turns riding him, then swapping positions for a double creampie finish. The camera lingers on the messy aftermath — one girl wipes her mouth, the other adjusts her hair calmly, like they’ve done this before.
