[Ikegami Tatsuya] Himitsu no Wanko Seikatsu (COMIC Situation Play vol.17) [MrBubbles]

A voluptuous beauty with glasses has been secretly raising Yuuta, her spoiled dog-eared pet boy, and bath time is where their devotion overflows—scrubbing his fluffy tail while he whines to be picked up like the puppy he is. When she breathes that they should 'become a real family,' she spreads herself open and coaxes her little pet inside, riding him until the bathroom fills with steam and her huge breasts bounce with every eager thrust. But secrets are hard to keep when Yuuta trots out into the street in a frilly dress to deliver her bento, turning an ordinary morning into public chaos.
