Pushing the thermometer out

I got it taken from my butt once by my momma. She asked me if I was pushing it, but I wasn’t. It was actually just slipping out, probably because I was clenching and relaxing constantly. So, then she put it in again and cupped my butt. Her hands were big enough. It kept it still.

I always liked having my temperature taken rectally the longer I had to wait the stronger the urge to push it out would become. Being over my mom's lap I would feel it slipping back in as soon as I tried to push it out. Which made it feel even better as I struggled to push it out as she held it n place.
