Kazuharu's first time experiencing the intense pleasure of anal fisting is captured in this raw, explicit scene. His mistress, a dominant femdom enthusiast, leads him through the journey of his virgin ass being filled by her skilled fist. She starts with a slow, sensual tease, using her fingers to stretch and prepare his tight hole. As he relaxes into the sensation, she pushes her fist deeper, making him grunt and moan. His ass struggles to accommodate her, but as he gives in, she picks up speed, fucking him with her fist until he can't hold back anymore, cumming hard and messy.
