Phase Two: Probe Testing

"The baseline measurement is confirmed," announced the Grey researcher. "Your health appears excellent, and your recent transplants are functioning normally. We will begin the testing shortly. As a side effect of the tests, you may experience various arousal and hormone levels during the testing, along with muscle contractions or fluid emissions, but this is completely normal." He then moved to a nearby panel and made a motion with his fingers. "Testing initiated," he stated.

At first, you couldn't feel anything different, and it seemed the probes weren't doing anything. As you waited for something to happen, you slowly relaxed, gradually becoming more accustomed to the large probes inserted so deeply into your colon and uterus. After a few minutes, you detected something which felt like slight pulsing emanating from the anal probe. After several seconds, the pulsing increased in strength creating a very pleasant throbbing sensation. When it increased still further again, it became an almost unbearable thumping deep in your colon. Finally, it reached an pounding level that pushed you past the limit, and the result was a deep anal orgasm that sent shockwaves throughout your lower body. For several seconds your body shuddered helplessly.

Only after it ended did you realize that the probe had stopped pulsing. "From the probe readings, this appears to be the maximum level you are currently able to endure," stated the Grey researcher. "To prevent damage to the probe, and to avoid possible injury, this will be the maximum level used for the remaining tests. Once you're ready we will resume the testing."

After catching your breath, you confessed, "The throbbing I felt was nearly intolerable. How much higher can it go?"

"You reached level four. For comparison, all of our Cuni test subjects easily handle level five, and most can reach level six. The highest we have successfully tested is level eight."

"Well, I guess reaching level four, which is half of the max, isn't too bad for my first try," you replied.

"Each level is exponentially stronger than the last. Level eight is actually several hundred times stronger than level four. What you just experienced is a only tiny faction of possible maximum."

"Only a tiny fraction!?" you exclaimed. How could anyone handle that much stimulus you wondered, and you suddenly felt a bit disappointed at only reaching level four. "I guess I'm ready for the next test."

Over the next hour you underwent a similar set of tests which included different types and durations of pulses and vibrations that steadily increased in intensity. Each time, they reached a point that exceeded your tolerance and triggered an unbelievably intense anal orgasm. Several of them also triggered a simultaneous release of fluid from your pussy which sprayed out over the floor in front of you. After a full hour of this, you were nearly exhausted. You completely lost track of how many orgasms you had along the way, but it far exceeded the number you'd ever experienced before in that span of time.
