Kasuga Mona works in a massage facility. Because this is not a sexual facility, there are regulations prohibiting customers from touching or having sex with staff, even the staff. Because she has an extremely attractive body, massage requires a lot of touching, so customers are often greeted by her. Looking at the pitiful "gun" that can only be "raised" but not "fired", Kasuga Mona immediately circumvented the law by "accidentally" letting the customer's cock show out and rub against her underwear. Then her underwear "accidentally" slipped off and the other cock immediately penetrated deep inside her cunt! Feel free to "shoot bullets" deep inside her uterus! After each massage session, customers are very satisfied with this "special service" of Kasuga Mona, she gradually becomes more popular, and of course the store still does not know about this...
