[Amamiya Mizuki] Mahou Shoujo no Mama Netori Manga [Satoru]

A vengeful mother with massive, heavy tits confronts her daughter's boyfriend, demanding "proper punishment" in a no-holds-barred sex contest after catching him in the act. The young man soon discovers the boy's younger sister is a magical girl wielding a wand that grants "Sensory Link," forcing both the buxom MILF and her magical girl daughter to share his overwhelming sensations while he teases their stiff nipples and soaked pussies. As the curvy mother and the flat-chested magical girl writhe in shared ecstasy, the boy holds all the power in this twisted, reality-bending family affair.
