"Give yourself to her"

Jessica advanced into the inner chamber, her pale skin practically glowing in the moonlight.

The chamber itself was rather small and modest in its design. The only structure of note was a short staircase, with a pedestal at the top. This, presumably, was where the artifact was kept. Jessica began to climb the steps.

As her bare foot touched the first step, the collar went from a gentle hum to a rather vigorous one. Halfway up the steps, she began to experience the same ghostly stimulation of her body she had experienced when she found the collar. This had the effect on her body such that, by the time she made it to the summit, she was a strong breeze away from an orgasm, Her pussy practically flowing.

Trying to supress the urge to drop to her knees and relieve herself, Jessica focused on the pedestal. It was actually a wooden sculpture of the goddess Inanna holding a box, presumably her artifact. Wanting this sexual horror show to end, Jessica opened the box.

Or, at least she tried to. The box didn't budge. There was another puzzle to solve. Jessica attempted to let out a sigh, but it came out more as a frustrated moan, low and slutty, as the collar continued to keep her on edge. She examined the statue a second time. There were no mechanisms she could see. She crouched under the box.

And was greeted with the sight of an 8-inch polished wooden phallus, curved upwards and around the box so a user could "commune" with their god face to face. This must have been what the etching meant when it said to "give yourself" to Inanna.

The normally rational Dr. Anderson would have looked for another way. The collar-stimulated, ****-to-strip-naked, supernaturally horny Jessica didn't give a shit whether it worked or not, and began to guide herself onto the wooden cock. As wet as she was, it took no effort for the entire length to slide inside her. Her head threw back into a low moan as it did, her sweaty, pert tits glistening in the moonlight. She began to ride the wooden dildo in earnest. The statue of Inanna began to glow as she bounced up and down. Motivated by this development, she sped up her cadence, breath quickening as she did so. Suddenly, the box opened. Without a second thought or consideration, her mind clouded by a primal need to cum, Dr. Anderson grabbed its contents mid-hump, and examined them.

It was a long bronze chain, with three endings, each with a leather clamp. It took her a moment in her current state, but her mind clicked as to where the clamps were supposed to go..

It was at this moment the collar took over.

Jessica's consciousness was pushed to the side in a wave of pleasure as her body continued bouncing on the ancient wooden dildo. Her hands, now moving on their own, manipulated the clamps with expert precision. Her nipples, already erect from her lewd display in the oasis, made for easy targets. As her hands closed the clamps on her nipples simultaneously, Jessica was hit with a wave of pleasure the magnitude of which she had never experienced before, like her brain was hooked up to a car battery. As she recovered from the stimulation, she realized where the third clamp was going as she felt her hand move in between her legs.

When the clamp contacted her clit, it was like fucking an entire power plant. Jessica's mind went white in the throes of a massive, twitching, squirting orgasm, and lost consciousness entirely.
