[My first love, who was neat and cute, was crazy...] A childhood friend I met again after a long time when I went back to my parents' house.She was already married and a married woman, but her country life was too idle and she wanted stimulation. The moment she loses to her temptation, "Hey, let's have sex while my husband is away" ... she suddenly changes suddenly.I was robbed of my movements and stuck in close contact with Berokisu, tied up and put in a piled cowgirl position, vacuumed in a vacuum, and I was turned into a cock guy in a nostalgic uniform.Drown in the darkness of a yandere woman who restrains both body and mind.
