Rules Are Meant to Be Broken

Story - Longtime friends turned lovers, Gianna Dior and Damon Dice's relationship was built upon trust and transparency. Already sexually adventurous on their own, together they were able to explore their fantasies freely, in a way they were never able to with previous partners. They made a List, and slowly began ticking things off. Gianna, who had finally just crossed girl-girl sex off her list, couldn't wait to get to 'threesome sex with another woman'. But there would need to be rules. Gianna would pick the girl. Damon would enjoy her, but no fucking her- and definitely no kissing her. These rules felt like the right thing at the time, but once in the heat of it allaren't some rules meant to be broken?
