One day, I suddenly got a message from a hot girl I barely spoke to in school... "I've become an Onahole Club girl, so come visit me♪ I'll give you plenty of service!" As a gloomy loner, she was out of my league, but I thought I might actually get to do something lewd with her! Excited, I went to the shop and got to do sexy things as expected, but she kept adding extreme options, and my wallet grew emptier and emptier. Then, she showed me a 'secret hidden option' and unexpectedly forced me into raw sex!?
