Their bodies were perfectly compatible... On a whim, Naoto ended up having a physical relationship with her son. At first, he was a substitute for her husband. It was just a physical relationship, a mere act of compensation. But now, she finds herself addicted to her son. Every day, she imagines being penetrated by his stiff penis and her underwear gets stained with love juices. Ahh... She wants to have sex with her son soon. Hiding her rotten desire, Naoto hands her bag to her husband with a smile.
