Late at night, I encountered a flashy gal lost on the street. She was at a festival but missed the last train, so I decided to let her stay for one night. Even though I was in someone else's house, I couldn't help but make a move on the gal in her swimsuit, who was too defenseless... "Can I do it with you as a thank you for letting me stay?" I was at the mercy of the gal's hip movements, and I fell in love with her unexpectedly cute gap...!
