Callie set her alarm for 8am the following morning. Remembering Keiran's instructions about taking her temperature, she picked up the pack that Hannah had given her and, without moving from the bed, she removed the thermometer from it's case and pushed the covers to the bottom of the bed with her feet.

Callie dipped the thermometer into the small pot of vaseline and then rolled onto her back. Lifting her legs towards her chest, she felt for her little puckered hole and then eased the thermometer into her bottom.

The sensation of the glass rod sliding inside her actually felt incredibly sensual and immediately Callie began to feel aroused. Surprised by the sensation, she played with the rod a little and slid it in and out of her hole a few times. Before long, her labia had began to swell and her vagina was slick with her arousal.

Callie allowed her fingers to slide through her wet folds several times and up over her clitoris until they settled either side of her swollen bud. It felt so good.

Touching herself like this was not something Callie did very often but now, as she lay with the thermometer still protruding from her bottom, Callie couldn't resist dipping her fingers inside herself.

She began to gently rock her engorged knot of nerves against her pubic bone and her pleasure soon multiplied, blood rushing to her sensitised sex leaving her moaning and writhing on the bed. It wasn't long before her breathing became heavy and raspy until finally, intense pleasure rippled through her in one enormous wave and the tension flooded out of her body.

Callie lay there for several minutes, basking in the awareness of how relaxed she now felt, her fingers absently taking in the sensation of the mattress that she lay on, her body perfectly supported in comfort. Her vagina and clitoris were now just happily pulsating as her body returned to its normal equilibrium.

Suddenly, Callie remembered the thermometer. Where was the thermometer? Did it fall out of her? Was it in the bed? She jumped out of the bed and pulled at the sheets, desperately searching for the missing glass rod. It wasn't in the bed. It wasn't on the floor either.... Oh no!!! Callie started to panic. There could only be one explanation....

Back on the bed, Callie tried to feel if the thermometer had worked it's way deeper into her bottom. She could feel something but was that the thermometer? She didn't know. She pushed her fingers inside her bottom but she still couldn't determine if it was stuck inside or not.

In the bathroom, Callie sat on the toilet and tried to push. If the thermometer was stuck up there, maybe that would free it? Still there was no sign of the missing temperature gauge. She also didn't manage a bowel movement.. and now her stomach was hurting. Callie was full on panicking now!

Very quickly, she ran a brush through her hair, cleaned her teeth and splashed water on her face before pulling on a little summer dress and flipflops. She decided that as embarrassing as it was, she had no option but to go over to the health suite and explain what had happened....
