Tricked Bi Zena

One of Goddess Zenas rubber slaves is brought in for conditioning and to improve his sexual abilities. After being tied to the inversion table, she explains that a slavegirl will be used to make him fully hard and he must resist coming. Unknown to him, it is actually a male rubber slave who uses his mouth to pleasure, Mistress guiding them both. The next phase is oral strapon training, he attends to the big rubber strapon until a point is reached and she replaces her strapon with a real cock, the blindfolded slave having no idea until she removes it and starts laughing and humiliating the poor slave at what he has unintentionally been doing!
