Recently, my son, Kiyoshi, has been inviting his good friend Yuzuru over to our house to play. I'm happy that my son has made a friend, but the problem is that Yuzuru seems to be aware of me as a member of the opposite sex... I gently refused, thinking it was just a young mistake, but a few days later, Yuzuru, who had a grudge against me, came to our house with his friends. He held me down as I desperately resisted, raped me many times, and came inside me. Since then, they have been coming over to gangbang me almost every day...
