Opening the drawer in the little table, Ianto pulled out the lube, passing it to Jack, avidly watching as Jack settled up on his knees, arse against his heels for the moment.
Jack held Spike's gaze as he flipped open the lube, slicking two fingers, rising up on his knees to give him easier access, slowly working them in. Sliding them out just as slowly, his breathing steady for the moment. Just pumping the fingers in and out, fucking himself despite the awkward angle. Adding more lube and another finger, a bit of a twist even with a limited range of motion.
His breathing quickened, his pulse rising as he imagined what he was told to, dead-pale skin against his own, cold flesh filling him and pressing against his back. The remembered sensation of his blood being pulled out of him, his life draining away. His pupils dilated, and he thrust his fingers a little deeper, twisting them as he pulled them back again.
