Dan noticed that Amy’s hand had found its way under her body and her fingers were moving up and down the outer lips of her vagina. This was causing some rhythmic gyration of her hips and gave him an idea. He slowly urged Julia’s bottom onto the two pillows he had stacked under her hips. He removed Julia’s thermometer, shook it down without reading it and slowly and carefully re-inserted it until only a bit more than an inch was visible. He then reached over and did the same for Amy and then announced that he would like to see which one of the two girls could get the hottest by touching themselves while their temperatures were being taken. Julia let out a soft moan and then reached under herself to position her hand and slender fingers.

Dan sat back at the end of the bed and watched with fascination as the two girls drove themselves to multiple orgasms. He noticed that each had a different technique, Amy paying more attention to her clitoris and occasionally burying her middle finger between her lips, while Julia seemed to concentrate more on moving her finger in and out of her wet front opening. Dan would occasionally reach out and alternately tap and twirl the exposed ends of the two thermometers, eliciting low throaty noises from each of Amy and Julia, paying equal attention to each so as not to favor one over the other.

After Amy and Julia had each experienced multiple orgasms, they both collapsed spent and silent with their upturned bottoms resting on their pillow stacks. Dan gripped the end of Julia’s thermometer and playfully removed it until only the bulb remained inserted and then slowly pushed it back in, repeating this several times and lightly running a finger up and down Julia’s well moistened lips while Julia spread her quivering thighs as far apart as she could. He then did the same for Amy, this time repeatedly completely withdrawing the thermometer and holding the bulb lightly against her entrance for a bit before reinserting it with a gentle twirling motion. He looked at the clock and noticed that their temperatures had been registering for about a half hour, announcing that it was time to compare the results.

Dan reached over and withdrew Amy’s thermometer, read out loud 100.7 degrees, then shook it down and then slowly re-inserted it into Amy’s waiting bottom hole. He then withdrew Julia’s thermometer, read out loud 100.9 degrees also shook it down and then re-inserted it into Julia’s waiting bottom. He then sat back and admired the view of the two upturned firm behinds with their inserted thermometers, both girls having their legs spread well apart, for what seemed like forever but was actually about another twenty minutes.
