Just check the yui's version. It's the same, but more awkward because the fat guy is in it. At first i thought this was some creepy disturbing fetish involving sex with a little guy, but it's more like a "cute" comedic av with the little guy acting as a 3rd wheel. It's a turn off, but I think the little guy is staying, but who knows maybe he'll have real sex or maybe he's actually sexually dysfunctional.
Yui like her best friend Hibiki is getting softer(not fat), but aged a lot more in the past 2 years. Idk if it's genetic, overwork, or her lifestyle, but they look like they're in their 30's. Yui short hair doesn't bring out her youth instead makes her even older. Akiho is in her 30's and been in the av industry for 15 years and still manage to keep her figure, but even signs of her age is showing through her face. Now I feel old since a lot of girls used to be older than me retired already and the new girls are younger than me. Next year the 2000's girl will join. I remember people on other forums talked about the 1990's girls starting.
