Nothing satisfies Mistress Kassy and I more than stretching out a slut and stuffing their holes. We test the limits of what our willing victim can take and see what kinds of whimpers and moans we can get out of him. Kassy warms him up for me, stretching him out with a big rubber cock followed by her fist so that I can slide my 12 inches right in. We leave him properly used and completely nonverbal, floating in subspace.
