You're doing some shopping after work. Caleb and his girlfriend happened to be there too. You heard about her, but never met. Caleb introduced you two and you recognized her. It's Melissa; the girl you used to date. You both were into the whole dom and sub thing back then. Melissa is blushing from recognizing you.

Melissa: "Daddy..." Caleb: "What the? Did you just call him daddy?"
