Riley's lips parted in a sigh and his back arched, pressing the crown of his head into the mattress. He was smiling, his chest heaving as he breathed deep breaths. Every so often his breath would hitch when Tao's mouth brushed over a particularly tender or sensitive spot. He let his entire body feel heavy and warm, despite the feeling of lukewarm sweat and blood crusting and congealing on the surface of his skin. "Ahh-" He groaned as Tao's mouth found his most sensitive spot. "Ah- fuck." His tone was regretful - it was true, he couldn't be away for too long, especially since now he would have to scrub the scent of sex off of himself so that no one would know what had happened.
