[Yamamoto Naoki] Saishin sakuhin-shū Vol. 3: 1. Watashi wa kyō mo kono heya ni kuru | New Series Vol.3: Five O'Clock, Ep. 1: “Today, I'm Back in This Room Again.” [Rainash]

An anxious young woman returns to the same room, where an elderly man begins teasing her with two fingers, then slides them deep inside her, igniting a shiver that runs up her spine as he combines his penis and fingers. She endures his careful kneading to loosen her back hole, her composure quickly slipping as the pleasure intensifies. The tension builds as the old man’s relentless touch pushes her toward an inevitable climax.
