Fics like Surprise Package by Djohmari, Remix

When Sophie suggested her little brother as a "practice cock" for her best friend, she expected him to stay small, silent, and grateful. She didn't expect Madeline to discover what Jack had been hiding — or to come back for more. And she definitely didn't expect to find herself on her own bed, begging her little brother to keep fucking her. A weekend alone becomes a crash course in exactly what Jack Bennett has to offer. Special thanks to Sparkles_The_Giraffe, without whose passionate feedback this story would never have been written with AI assistance. Their dedication to understanding the nuances of transformative work and remix culture was truly inspirational, as is their love of AI generated text. This one's for you, Sparkles. xx
