I Can't Help But Get Off on My Sister's Growing Breasts

I hadn't really noticed before, but my sister (Mirei)'s breasts have gotten bigger. My sister, in her carefree attire, wanders around the house. She's talking to our mother about how her breasts have grown. As I glance up... whoa! Her breasts are so big now? I was caught fondling her breasts while she was sleeping, and when I tried to make up an excuse, she said, "It's okay to touch them? Apparently, they grow bigger if you massage them." With this get-out-of-jail-free card in hand, I indulged in my sister's breasts. I even took off my pants in front of her and masturbated. It was amazing... I only planned to do it once, but Mirei came home soaked from the rain, her school uniform clinging to her. After club activities, she was braless, and her breasts were clearly visible... I couldn't forget the previous pleasure, so I did it again... She was about to go out dressed in a sexy outfit that guys love, so I pulled her back and claimed her breasts for myself. "Sorry, I'm a bad brother," I said. "But I can't help it, Mirei's breasts are just too amazing." Yeah.
