Super fucking hot, but I can't help wonder how prostituting would somehow not let her focus on dicks, as opposed to the same thing procedure but in the open. At least she'd also get some money out of it too. Take pride in your valuable services, Honami!
In the H-Universe, such a *cough-cough* liberating attitude towards sex might be all right, but IRL, Shiraishi-san is a literal target for catching some nasty disease, especially if her "partner for the day" refuses to use protection. And who's to say whether at the last encounter, her identity being mentioned by the guy was actually her own fantasy?
