Adapted from Karami Zakari manga by Katsura Airi and Miike Kei.

Even though I liked it first...Karami Zakari, the pioneering and monumental original work of BSS works. Takanari Yamagishi was interested in Riho Iida, one of the group of four close friends. A girl in the midst of adolescence who just wishes for love to come true. Takashi Yoshino is Takanari's best friend. She's happy and has a lot of sexual desire. He is especially close to Tomino Niiyama, with whom he gets excited, and the two are also members of a close group. Niiyama took advantage of Takashi's curiosity, who has a strong sexual desire, and the wheels began to turn. The beginning of sex happens in Takashi's room. An unstoppable feeling. The scene of Takashi and Niiyama having sex unfolds in front of Takanari and Iida. The two of them could only watch in silence, but when the matter was over, Takashi called out to Iida... There's no way Iida would accept it just out of curiosity...I'm sure he'll stop at some point...

The desires of the four members who had their first sexual experience in the previous work accelerated, but now that summer vacation has arrived, Takanari is the only one who has no choice but to spend his time studying for entrance exams. Meanwhile, Takashi, who is taking a break from club activities, spends all his free time having sex with Iida and Niiyama. SEX reports and post-mortem images sent from Takashi almost every day. Even though I was feeling frustrated and frustrated, I continued to study hard...Is it really necessary for me to throw away my youth and lose my summer vacation, which will never come back, to pursue my studies? The doubts that rose in Takanari's heart grew bigger day by day, and before he knew it, Takanari was at Takashi's house. When I stepped into the unlocked house, Takashi was once again indulging in sex. ...Iida is my only opponent.

This is a special edition that depicts the summer story of Iida, Takanari's crush, and his best friend Takashi, who were busy developing their sexuality. Takashi, who is pursuing sexual pleasure, is enjoying threesome sex with Niyama and Iida, and had planned to enjoy threesomes today, tomorrow, and all summer, but Niyama is going on a family trip. While he is reluctantly indulging in masturbation, Iida arrives alone. Iida is also drowning in the pleasure of sex that he has just discovered... He is silent, but occasionally shows his naughty nature, his body flushes with the intensity and summer heat, and his whole body throbs with pleasure at being developed... They lose track of time and simply mix together, covered in sweat.
