The Training of and Anal Slut, Day Three

Penny Pax signed up for four days of slave training. By day three she’s bent over, wrists cuffed to her ankles, mouth open around a red ball gag. Sweat runs down her back while her trainer works a thick plug deeper into her ass, twisting it every inch. She grunts and clenches, but the steel frame holds her steady. No mercy. Just slow, deliberate pressure until her hole gives and swallows the widest part with a slick pop. Her thighs shake. Blonde hair sticks to her face. The plug stays in while a leather strap is buckled around her waist and pulled tight between her cheeks, keeping everything buried. She breathes hard through her nose, eyes glassy, learning the difference between taking cock and actually serving as an anal slave.
