Artemis and her Huntresses of course!

Percy blinked, slowly coming to, and stared up at Artemis' beautiful, black face. "Wuh... Lady Artemis?" he mumbled. The goddess, who was apparently carrying Percy, smiled down at him. She wiped some of the cum off his face and fed it to the demigod, who eagerly swallowed the yummy treat.

"Hello, Percy. You see, after I left you in the forest, I realized my Huntresses and I tend to get very... pent-up during our Hunts. Sure, we can always blow each other," She paused. "Or, well, they can blow each other and myself, I would never service my subordinates. Anyways, the point is that blowjobs aren't always enough. What we need is a slut to use. And that's where you come in. You're gonna be the new fucktoy of the Huntresses!"

Percy didn't know what to say. Part of him wanted to scream, "Fuck no!" and run away, but another part, a louder part, one that, before, he didn't know even existed in him, wanted to scream "Fuck yes!" and get started on pleasing the Huntresses immediately. Before he could make up his mind, Artemis loudly announced, "We're here!" and unceremoniously dropped the demigod.

As Percy looked up from the ground, he realized he was surrounded by the other Huntresses, each of whom was packing massive meat; they were all at least 8 inches long and two inches thick, a variety of races and colours. Percy's own tiny dicklette spasmed, becoming painfully hard, and despite himself, Percy couldn't stop from drooling as he stared at the dicks.
