Sarah

The nurse had the rectal thermometer in hand.

“Did she make it?”

“Barely” said Allyson.

Sarah could see the outline of Emily’s ass and pussy on the couch from when she had sat on it and also where here hands, knees, tits and face had been when she was on all fours. Her sweat and cum stains were quite the embarrassment.

Emily dreaded the thermometer she loved tiny fingers like Allyson’s and Sarah’s but this thing was huge.

They both smacked her ass and led her to the couch where she fell onto all fours again before deciding to preemptively spread her cheeks baring her asshole and spreading her pussy to the three.

“Sarah, would you like to do the honors?” Asked Allyson purposely trying to cut the nurse out of touching Emily.

“Sure! Should I lube it?”

“It’s your call I think she could take it either way.”

Emily was shaking from arousal, fear, and anticipation. She couldn’t handle that thing without help but she didn’t want to get in trouble. Sarah decided to follow Allyson’s lead and dipped the first three or so inches into Emily’s vagina and coated in natural lubrication. Emily moaned loudly and pushed herself back on the thermometer trying to fuck it but Sarah pulled it out leaving Emily frustrated.

Sarah smacked her ass hard. “You dirty slut.” Sarah said with a giggle and Allyson and the nurse laughed as well.

She felt the base of the massive thermometer at her anus and couldn’t help but clench. Sarah didn’t stop though so she **** the beginning in. Allyson rubbed Emily’s asscheek while Sarah kept pushing.

“You need to take it all so we can find out if you’re sick.”

Emily sobbed and grunted as she realized they meant for her to take the whole thing. This was all based on lies. She wished she could have just stopped edging and avoided all this.

The thermometer was about half an inch in and it was alright stretching her wider than Sarah’s fingers had. She cried at the pain but she also felt her loins stirring. Her juices were dripping down her inner thigh. She pushed her ass back against the thermometer grunting more as Sarah **** it more and more and Allyson rubbed her ass.

It was finally to it’s full width about an inch in and Emily groaned in pain. She bit her lip to keep from shouting and getting punished. Sarah was moving it in more and more but sometimes she’d stop and pull it out a little fucking Emily’s ass with it as Emily grunted and moaned while she tried to stretch her cheeks more to give her some comfort.

Allyson took her free hand and started playing with the area around Emily’s clit trying to not let the nurse notice. Emily moaned loudly pushing herself back on the thermometer taking more and more of it. She wanted to finger herself. She realized having her ass take this thermometer was turning her on and she felt more shame. She was a disgusting butt slut. She giggled at the thought and that concerned her friends who were worried she was breaking mentally.

Finally after several minutes of pushing from both sides it was in all almost all the way and Sarah took one finger and pushed it down so that only the bulb was outside Emily’s ass as Emily let out a final grunt and moan. She could feel her asshole stretch to about two inches and the bulb resting against it.

The nurse loved that this naked slut was being punished for her behavior. Flaunting her naked body so the boys chase her was disgusting or so thought the nurse. Finally the nurse saw the the process was complete.

“How long should we keep her like this?” Asked Allyson.

“You know I like a good while to get a real accurate read. Why don’t you take her to her next class and then we’ll come back and check it out.”

Emily was dumbfounded. They wanted her to walk around with a thermometer up her ass for an hour.

“Sounds good to us.” Said Sarah who helped Emily up. Emily now standing with the thermometer snuggly up her anus and deep into her rectum didn’t want to admit that at some level it was adding to her horniness. Both of her friends grabbed her by a nipple and started leading her out of the room.
