Aoi, a girl I met through a dating site. She seems to have trouble around men and says she wants to overcome it, so I pretend to listen to her problems while pushing to act like lovers. Despite being naive—agreeing to go to a hotel together on our first meeting—she's shy, reserved, and passive, unable to take initiative. I gradually escalate things by seducing her, using kisses, body contact, and suggesting that couples would naturally film themselves having sex. But then, an unexpected turn of events! When I take her doggystyle and thrust hard and fast, her small nipples become fully erect—an unbelievable reaction that leaves me shocked again and again!
