"You're so hot," Mark murmured, kissing down my neck, his hands holding my waist tightly.

"Omg Mark, we're siblings," I giggled, although I wasn't complaining ;)

"Step-siblings," Mark corrected with a smirk. I nodded my head, understanding his logic. Of course, we're not related by blood and although we grew up together as siblings, it's fine!! :)))))
