Is there a hidden option for secretly filming massage parlors? SPZ-1144

I went to a massage parlor to relieve my fatigue. Because it was a new place, there were no assigned masseuses; instead, a staff member appeared as cute as an idol. However, after about 20 minutes of the massage, I noticed that the staff's massage skills seemed rather poor…? No, that can't be… I chatted with them casually and discovered that their "hidden option" was actually sex services—this was the true nature of the parlor. This video includes real sex scenes of four of the staff members.
