ALDN-504 Mother-in-law, you're so much better than my wife... Koda Riri

My wife and I went back to her parents' house for the first time in a long while. My parents-in-law welcomed us warmly. During a family get-together, my father-in-law said he wanted to see his grandchildren, and my wife suddenly became upset and left the table. I told my parents-in-law, who were confused, that my wife was refusing to have sex with him at night, and that even if they tried to seduce him, it wouldn't work. I felt bad for them, seeing how disappointed they were. I woke up in the middle of the night to go to the bathroom and stopped in front of my parents-in-law's bedroom, where a light was leaking in. I peeked in and saw them having sex. I knew I shouldn't look, but my sexual hunger made me unable to look away. My erection wouldn't go down, so I started masturbating in secret, when my stepmother came in. As I hastily hid, she told me to wait, saying, "You're going to get pent up because your daughter hasn't done it yet, right? If you'd like, I'll do it," and began stroking my penis. It had been a while since she'd touched me, so I quickly became aroused, but my stepmother's hand and oral were so skillful and sticky that they didn't seem to allow me to ejaculate, and just as I reached my peak, on the verge of exploding, she took it in her mouth... The next day, my father-in-law and my wife went out to a nearby izakaya. My mother-in-law must be feeling awkward because of what happened last night... And it was getting late, but my father-in-law and his wife hadn't returned. I made up my mind and headed to my mother-in-law's bedroom. As my mother-in-law was snoring, I gently lifted the covers and began to caress her. Soon, her private parts began to make squelching sounds. She woke up in surprise. I couldn't hold back any longer, so I inserted myself into her, almost as if I was about to attack her...
