A younger sister "Shuri" and a solid older sister "Mikako" are delighted to return home for the first time in three years. Shuri innocently tells her feelings for her brother and forcibly approaches to forbidden incest. However, the act was witnessed by Mikako, and Mikako also told her brother about her secret feelings and asked her to embrace her. While knowing that sisters who love their brothers as much as each other will never be tied, they begged their favorite brother for the last sexual intercourse. Popular actresses "Shuri Atomi" and "Mikako Abe" play TMA's popular incest drama series sweetly and painfully.
