A tragedy that occurred when she was found without a bra... Her innocent nipples, still in the process of development, were violated by a perverted middle-aged man, who relentlessly targeted her nipples and attacked the girl after school. The buds at the tip of her undeveloped beautiful breasts were pinched, grabbed, and pulled by the dirty old man, gradually becoming more sensitive. Before she knew it, her nipples and Kokoro were corrupted, and she went crazy, screaming, "My nipples are hot!"
