A J● massage parlor located in Gotanda, known for its strict rules of no ejaculation and no touching. However, contrary to these official policies, all the girls working there were reportedly engaging in private negotiations for hidden services. Online rumors have long circulated: "Those cute J● girls probably do hidden services all the time, right?" To investigate this urban legend, we conducted an undercover interview with a girl we'll call K-chan (pseudonym). The results were shockingly beyond expectations—K-chan admitted to frequently performing hidden services. Her revelations were so surprising that it seemed as if the girls were actively initiating these encounters themselves. By the end of the interview, she gave a deep-throat blowjob, followed by a creampie—delivering an absolutely incredible experience.
