Marked Where It Shows. After Hours, #1

Victor shoves her back against the desk, his grin pure filth, and rams his cock home in one agonizingly pleasurable stroke. Then he grabs a thick black permanent marker and writes "Victor's" on her - the letters smear as her sweat bleeds into the ink, but they're there. Ownership - the kind that leaves a mark. Marcus pins Tessa against a desk with her dissertation scattered like torn secrets and demands a permanent seal.
Adrian backs Claire against his desk, his tie swinging like a noose, and growls "you've been dripping for me, haven't you?" Nolan spreads Paige in a study room, stretching her impossibly wide. Marco molds Nina against a studio wall with her hem hiked high. Grant drags Sophie up stairs two at a time and she hisses "you're fucking mine." The mark is literal - permanent marker, bruised skin, ownership written on the body.
