Love bro and Yuya. Yuya is an extremely weak insect, and his sister's skin is overprotective against Yuya. One day, Yuya happened to pass in the vicinity of the neighbouring dqn, and the dunk was passed. QN, who had a grudge against him, later set aside the house, pressed the house in the time when Yuya was not there, and forced the nude troupe against the cock of the decadent.
