I Silently Ravaged My Sister After She Started Cosplaying as a Magical Girl Kotone Fuyuai

My sister Kotone used to be shy and introverted, always embarrassed to appear in public. But when she puts on a cosplay outfit, she transforms into a completely different person—bold and outgoing. It all started with a simple photo shoot with her older brother. Gradually, the atmosphere shifted. What began as an innocent session soon took a lewd turn as her aroused brother escalated his actions. Kotone's crotch was exposed, her brother gripping his cock, forcing it into her mouth. Though trembling from these first-time experiences, she felt her pussy thoroughly licked until dripping wet, awakening sensations she'd never known before. In that moment, she became aware of herself, and a new emotion began to bloom within her.
