One day, I was caught in a downpour on a business trip and ended up sharing a room with Sayama, a plain, gloomy girl I'd never spoken to before... The conversation didn't continue and an awkward atmosphere spread. However, when she took off her jacket, her wet, voluptuous breasts caught my eye, and I couldn't resist her body, which looked so comfortable to hug, so I pushed her down on the bed! If it was just once... she was quiet, so I wouldn't have to worry about her telling on me. But this one thrust awakened Sayama's pent-up sexual desire! "I'm so happy that you've gotten so hard from me..." She straddled me with an aggressiveness I can't imagine from her usual self, and her titty fuck and blowjob techniques made me cum all night long...
