MNDO-002 — A Housewife's Secret Part-Time Job: I Tricked Her Into Being An Underwear Monitor, Made Her Make Stained Panties, And Then I Cum Inside Her!

A housewife who came to work as an underwear monitor is told, "Please leave some bodily fluid stains on the underwear to test its waterproofness," and "The reward will vary depending on the amount and quality of bodily fluids you get." The person in charge then leaves a large amount of adult toys, including electric massagers, vibrators, and rotors, and leaves the room. The housewife, left in the room, is confused, but in her mind she is filled with a desire for reward and an interest in the adult toys she has never seen before... We managed to spy on two housewives!
