It was my mother, 43-year-old Yasuko, whose appearance stirred my sexual desire. While sneaking behind my father's back, the day we had sex began by drugging my father into unconsciousness, then touching my mother's body right beside his sleeping form. I inserted a toy, made her suck my dick, and grew increasingly aroused. Even after ejaculating into her mouth, I wasn't satisfied—so I licked her pussy and thrust my rock-hard cock into her, making her writhe in silent agony. Watching her face, I wanted to thrust deeper; she squirted repeatedly, showing me her most depraved, uninhibited self. In the end, I came inside her.
