[TINGA (Kochinko)] Hamedori! Magic mirror truck

A cash-strapped boy borrows a ten-thousand-yen "gift" from his girlfriend's bright best friend, Rina, only to discover it's a vibrating, piston-driven adult toy built to stimulate his prostate. After anxiously trying it alone in his room, he finds himself desperate for more intense relief, and Rina eagerly steps in to help him reach a trembling, messy climax. The story closes with Rina confessing she wants to taste his next load directly, pushing their steamy, toy-fueled encounter into even more intimate territory.
