They are needed for a perverted ritual.

"Well, to the matter then." The sorcerer claps his hands and five priestesses in purple robes wearing black silken masks and caring bronze bowls enter into the chamber. "I need from you one simple thing," The Stygian begins to lecture, "your seed. You will masturbate and give forth the life fluids into these bowls." One priestess goes to each pillar and after placing their bowls on the ground, unceremoniously removes the prisoner's linen wrap, stripping them naked. Painted on the prisoners' lower abdomens are elaborate snake runes, with the serpent's tail pointing down towards the their genitals. The women then remove their robes, likewise stripping themselves bare, save for their masks and kneel before their captive. Though their faces are hidden, all have beautiful bodies, though none as pleasant as the red haired Hyrkanian.

"The first four to perform their labors", the Stygian continues, "will be paid a sizable sum of gold, with the quicker one's receiving even more coin, and then all four will be set free. If you refuse, however, then I will have you castrated and take your seed by ****. If that is not incentive enough, however, know that one of you must be sacrificed to the great god Bel. The one who fails to give up his or her seed will be the one so condemned."

The wizard notices the Zingaran pirate gives a puzzled look at Sonja. "Concerned about the woman, Rimondo? Hmm, typical." The Stygian answers. "You think it unfair for a female to be in this contest? Surely you of all of us men known that more whorish woman can become so excited that they too can give forth their fluids. Why it is a famed characteristic of the prostitutes of Corinthia. Besides, consider her a gift of the gods, the sight of her naked body should aid you in your task and her gender should work in your favorite."

The Stygian again claps his hands and the prisoners shackles are released, freeing their hands as the priestesses hold up their bowls. "Now warriors, begin the game, and know the generosity of Thoth-Amon, or his wrath."

Instinctively, Sonja covers herself with her hands and arms while the Khitani monk immediately grabs his manhood and begins to stroke it. He stares at the she-bandit with a look of loathing. The Kushite first tries to rend his bonds and then grab the priestess beneath him. When these meet with no success, he grabs his massive, thick, cock with both hands and yanks on it back and forth. The Zingaran pirate is next, followed by the Ophirian centurion, who gives a martial nod of respect to his female opponent. All now stare at the bound naked Sonja who turns her head away in disgust that men could so easily be aroused.

"Dogs." She thinks. "The lot of them."
