In her first experience she was still a virgin... she had fingers inserted into her anus while covered in chocolate, but since then she's been training her anus with enemas, whipping, bondage, and vibrators. By the third time, she'd decided to seriously develop her anus. Starting with preparation of her unused anus, she carefully plays with her anus in the bathroom. She places a small ball on her buttocks and slowly inserts her index finger, rotating it gently. Next, she gradually pushes in two fingers, rotating them to trace the inner walls of her anus. While loosening the inside with her fingers, she repeatedly circles them around, then hooks her fingers upward to lift and stretch the anal ring. She vibrates her fingers to make the sphincter muscles tremble, stimulating them to make her anus deeper and softer.
