Serina and Yuimi are two sluts. I mean... They're two sisters
that go to the same college as teacher and student respectively. They have boyfriends
who are students at their school. Serina's boyfriend, Naoya, tortures her and
forces her to do all types of stuff while Yuimi's boyfriend, Yuta, is super-shy
about her advances.
And here I thought that the two
girls were gonna switch places to take care of each other's boyfriends. But I
soon realize that there's a pattern for Kitty's releasing of their "Pleasure
Pack" (degrading shot first, semi-comedic shot afterwards), and wasn't expecting
too much in the plot department. I'd recommend it if it hadn't been saddled with
another hentai outing (from the same company) called Midnight Milk Party.
