HBAD-719 Yui Sayama is a quiet, busty female student who is shy and not good at talking, but who is targeted by men because of her sexy body.

Yui is a vocational school student who works part-time as a cleaner and is shy, so she rarely talks or interacts with people. Although it's not obvious from her clothes, Yui has a nice body with G-cup breasts, a slim waist, and a big ass. When her coworkers and coworkers find out that she has such big breasts, they take advantage of the fact that she is quiet and doesn't seem likely to refuse, and force themselves on her, playing with her sexy body as they please.
