Based on the popular doujin work “Boku no Shiranai Himitsu no Natsuyasumi” by artist Hito Kiyama (Circle: Mori no Hito), this official collaboration transforms the youthful charm of a summer crush into an intensely stimulating onahole experience.
The dual-layer design blends firm outer silicone with a soft inner core. The exterior provides a strong grip and sharp stimulation, while the inner material delivers a moist, tender sensation that wraps around you.
At the entrance, thick material ensures tight suction right from the start. As you push deeper, soft vertical folds and fine horizontal ridges intertwine to create a slow, enveloping stimulation that captures the sensation of a secret, unforgettable summer encounter.
Crafted in Japan, weighing 450g, this closed-type masturbator balances realism, durability, and pleasure — perfect for fans of story-driven erotic fantasies.
