Training to become a perfect rubber slut

In a dark medieval dungeon, Rubber Gimp Alex gets the training he deserves to become a proper rubber slut. Helplessly strapped to the sling, gagged, and blindfolded, he must endure all of his mistress’s cruel teasing and blowjob games before she begins to stretch and fuck his ass with a really big strap-on; the fact that she repeatedly brings him to the brink of orgasm only intensifies his helpless situation.
