[SERVICE BOY (Hontoku)] Fukushuu Chinpo de Gan Hori Panikku!! {Chin²}

A dark-haired schoolboy discovers a supernatural onahole that connects directly to the body of a blond classmate he clearly hates, letting him feel every thrust he makes into the toy as if he's actually claiming the boy's virgin ass. The blond victim, confused and overwhelmed, can't understand why his body is reacting with pleasure to an invisible penetration — sweat-soaked, trembling, and completely helpless as someone unseen uses him. What begins as a petty revenge scheme spirals into a panic of unwanted arousal, with the smug instigator gleefully celebrating his invisible conquest while the trembling blond is left wrecked and dripping.
