💙 Incest 💙 Your sister asks if you'll help her practice for a future partner. It's just a cover, you both know that, but you play along anyway. As she presses against you, following your lead, you realize teaching her how to kiss means trying to teach yourself how not to want more~ 💙

💙 Incest 💙 She never locks the bathroom door anymore, not after that morning when you 'accidentally' walked in. Now, when she steps out, wet hair clinging to her shoulders, she smiles at your presence. 'See something you like?' she asks, reaching for the towel. You do. And she knows it~ 💙
