A year after my wife passed away, I started living with my son and his wife. I'm a health-conscious person, and I take supplements on a daily basis, so my lower body is still in great shape. So when I see my son's wife, Goba-san, I get turned on. However, I only thought about it in my head, and never thought about crossing the line. ...That is, until yesterday. It seems that I accidentally took my son's erectile dysfunction drug, and no matter how many times I masturbated, I couldn't suppress my sexual desire. If I continued like this, I might rape Goba-san... It was only a matter of time.
