I saw him grab a box cutter, my cock gave an excited twitch. He held it out to me. “Show me.” “How?” I already knew what he wanted me to do, but I needed to hear it from him. “Carve it into my skin,” River said, sounding breathless. “Mark me, Theo.” I stared at the box cutter, my mouth dry, then reached to take it with shaky hands. “Are you sure? This will probably scar.” River rolled his hips up against me, grinding his cock against mine. “I’ve never been more sure of anything in my life. I want you with me forever, and I want the whole world to know I’m yours.”
