I liked her first… A pioneering work of BSS with an original story that stands as a monument.
Takase Takashige had been interested in one of his close-knit group of four friends, Iida Rina. Just wishing for love to be fulfilled during the height of puberty.
Toshifumi Yoshino is Takashige's best friend. He's a bit of a joker and very horny. His vibe matches well with Shinoyama Chino, and the two are also members of the close-knit group.
The gears started turning when Chino gave in to Toshifumi's curiosity.
The beginning of sex happening in Toshifumi's room. Unstoppable emotions. The scene of Toshifumi and Chino having sex right in front of Takashige and Rina.
The two could only watch silently, but after finishing, Toshifumi called for Rina…
Just out of mere curiosity, there's no way Rina would accept it… Surely, surely he'll stop somewhere…
He thought so, but suddenly Takashige heard Rina's moans.
