I lost my wife and lived alone, but my son and his wife asked me if I wanted to live with them. It's been six months since I started to feel even less energy in my lower body. I've been trying to do something about it, but I just can't get it up. I thought I was young, but reality doesn't work that way. I watch porn DVDs, and even when I sneak a peek at my son and his wife's nighttime activities, they don't say a word. I'd like to have sex with my son's wife Yua, who has become strangely sexy recently, if possible... I was feeling depressed, but recently Yua has been doing things that make me think she's trying to seduce me. She's wearing loose clothes and no bra. The other day, she was showing me off without any underwear and provoking me. When she said she was going to take a break in that outfit, I lost my reason for a moment and attacked Yua. I played with Yua and got her excited with toys, but I couldn't get it up even when it came down to it. I was brought back to reality and trudged back to my room, even though I tried to touch and lick her, but I still couldn't get it up. Yua, on the other hand, was playing a prank on her father-in-law, hoping to excite him a little and cheer him up. She never thought he would attack her, but she regretted provoking him too much. However, she had expected to be raped by her father-in-law, who had suddenly taken out his manhood, but the fact that he didn't go all the way made her feel strangely frustrated. A few days later, I finally took my hand on the forbidden fruit. A few minutes after putting one in my mouth, I went to peek at Yua's bath and had a moment of joy. I dashed into the bathroom with force, showed her my raging lower body, and made her stuff it into her mouth...
