Kimura Mako Shameless Diary Prank Turtle Shota-kun Chibi, 91 min

Kimura Mako has a problem... her sister just suddenly dumped her stepson, Toshi, on her doorstep while she goes out of town! And Toshi is...well, he's young, and, to be delicate, he's a simpleton. Kimura doesn't know what to do with him, until, in his innocent playing with toy cars, he starts to drive them on her stomach. And down her leg. And up her breasts. And down, down, down, to her panties. Hmm...maybe she can find some use for this boy afterall.....
