This role-play is performed by adults. After my wife died, my adult son and his wife suggested sharing a two-family home so I would not have to live alone. His devoted wife Rio Kuriyama cares for me tirelessly with a smile whenever I feel unwell. One day, I accidentally see Rio having sex with my son—and she realizes I was watching. Still smiling as sweetly as ever, she continues caring for me in a very different way. Her full-body pleasure service makes me climax again and again without even allowing me to thrust my hips.
