Roommates Mari and Erika often look after their neighbor, a young boy named Shota. One day, while Mari is helping Shota study, she accidentally falls asleep. Running out of space in his notebook, Shota playfully starts writing on Mari's butt. What starts as a simple prank quickly spirals into an unexpected, steamy situation.




















*Both have sexy butts. It looks great in a full-length T-back. A bit of a plain type and a bit of a gal, they both have their own personalities. I laughed a little at writing the calculations on my butt. Well, it's big so you can write on it. It's going to be a 3P at the end, but it would have been better to have 2 people at the same time if possible.
Just my personal opinion, but I think it would be easier to stay focused if they just stuck to one actress.
I'm not particularly a butt-fetishist, but getting to see H-scenes with both Mari Koizumi and Erika Misaki feels like a bonus. If we're talking about butts, Erika Misaki might be more my type. There was graffiti on her butt, and for some reason, they used lotion to wipe it off... watching her get turned on while being touched was pretty hot. Then, for some reason, she gets fingered and starts feeling it... straight into the H... the pacing and her receptiveness are fast and fun! The positions, like the reverse cowgirl, were great for showing off the movement of her butt.
