Saaya Kirijo works in a massage parlor. Because this is not a sex facility, there are rules prohibiting customers from touching or having sex with the staff, even the staff.

Because she has an extremely attractive body, and massage requires a lot of touching, customers are often "salute" to her. Looking at the pitiful "gun" that can only be "raised" but not "fired", Saaya Kirijo immediately circumvents the rules by "accidentally" letting the customer's cock show up and rub against her underwear. Then the underwear also "accidentally" slips off and the cock immediately penetrates deep inside her pussy! Freely "shoots bullets" deep inside her uterus! After each massage session, customers are very satisfied with Saaya Kirijo's "special service", she gradually becomes more popular, and of course the shop still doesn't know about this...
