VO-047 - I was investigating, but I couldn't help myself after hearing them having sex

The 47th installment of the legendary 'Virtual Onani' series! Private detective Nana infiltrates a house for an investigation, only to be overcome by the sounds of the owner having sex with a woman. Unable to control herself, she begins to masturbate while hiding. Once the owner leaves, she sneaks into the living room, but instead of investigating, she starts masturbating on the sofa. She changes into blue lingerie, slides down her see-through panties, and orgasms using a toy.
