My wife and I live with her mother, my mother-in-law Kozue-san, making us a family of three. We decided to renovate the room, but due to work, we had to sleep in the same room for about a week. On the first night, unable to sleep due to nervousness, I couldn't take my eyes off my mother-in-law's massive breasts visible through my wife. I thought about quietly approaching and grabbing them but held back. On the second day, my mother-in-law's enormous breasts were still swaying through my wife. My wife was sleeping soundly, and unable to hold back any longer, I moved next to my mother-in-law. Enjoying her soft breasts, I became curious about her crotch and gently slipped in a finger. The excitement became unbearable as I felt the moistness seeping out, so I quickly left the scene and rushed to the toilet to jerk off. The next morning, my mother-in-law softly whispered to me, who was sleep-deprived, that she wasn't angry about what happened yesterday. That night, while I was quietly sleeping, I woke up to a pleasant sensation. Looking down, I saw my mother-in-law with her face buried in my crotch, sucking on me. As I panicked, she said, You did it to me yesterday too, right? and took my ejaculation into her mouth, swallowing it all...
