The room is filled with the scent of rubber and the sound of water sloshing in the bag. The sub's asshole clenches and unclenches, a symphony of anticipation. The dominatrix, her blue latex glistening under the harsh lights, leans in, her breath hot on the sub's ear, "Are you ready to take it all?" She squeezes the bag, and the water flows, filling the sub, stretching them, until they're overflowing, their asshole dripping with the dark blue liquid, ready to be fucked raw.
