It was half a year ago that I started doing "erotic things" with my childhood friend Takara, who I met again for the first time in three years. That day he was seen comforting his aching back while calling Takara's name.

Takara said to Gaku, who was about to burst into tears in shame, "When Gaku feels good, I'll touch him like I used to." He tries to convince him that it's for pleasure, but his love, which was about to give up while he was away, becomes hot and violent, and he drowns in his sex friend relationship... Swinging around with a burning body, passing first love!
