Sumiko admires her abs and belly, then fingers her belly button, when Lora comes in and sees her. She asks to play with her belly, but Sumiko brushes her off. Lora, annoyed, wants to make a deal. Sumiko tells her that if she can hurt her stomach she can play with her belly, then leans against a wall with arms up. Lora tries punching her belly, but the blow does nothing. She tries a couple more punches and claws Sumiko’s belly, to no avail. She caresses her belly, but when she gets to her belly button she shoves her finger in deep. Sumiko grunts and squirms in pain. Lora pulls the finger out only to keep digging more fingers into it, tormenting Sumiko’s navel. Sumiko passes out standing up.
Sumiko wakes up on a bed with hands tied above her head and her belly completely exposed. Lora walks in, and Sumiko pleads to let her go. Lora rubs her belly and plays with her belly button, commenting on how sexy it is. She uses a Q-tip, the eraser end of a pencil, her fingers and tongue on Sumiko’s belly button. They talk back and forth, and Sumiko is forced to accept that Lora owns her belly button. After a lot of play, Lora gets up and leaves Sumiko tied up.
