I called out to a college student couple I found in the city and said, "If you can withstand tickling for 5 minutes, we'll give you a 300,000 yen trip voucher!" At first, she tried to hold back, but it gradually escalated, and even though her boyfriend was behind her, she was stimulated in her sensitive parts, writhing and moaning. In the end, she had sex with her boyfriend, 30cm away from her through a mirror.
