The little sister decides to make his morning wood her pet, and every morning she comes to see him, nuzzles him on the cheek, kisses his head, and uses her vagina as a house for him to insert it! She acts cold towards her brother because he's a nuisance, but her brother's morning wood is so cute she can't help but fall in love with him! In the end, she even starts to feel like a pet, and gets cozy with his lower body while putting on cat ears! A love triangle between a brother and sister, incest!
