In the first part of the 'Harem Route', Ayane, Hinata, and Manami gather around Tenioha, their curiosity piqued by his newfound confidence. As they chat, the girls can't help but notice the bulge in his pants, leading to playful teasing and groping. Ayane, the boldest of the bunch, suggests they spice things up with some toys, and the room fills with the buzz of vibrators and the moans of four friends exploring new heights of pleasure together.
