Sweet Ben/Leslie story where they don't realize who each other is. This is post episode "Ann & Chris" but prior "Anniversaries" in season 6.

Ben's ex girlfriend pays him a visit with big news- turning his life upside down and everyone against him. Warning: This is sexually graphic! This story takes place post episode "Ann & Chris" and is pretty cannon up to that. I pictured Tina Fey playing the part of his ex "Tina" This is my first story so feedback is appreciated good or bad!
