This is my story
I remember my first temp like it was yesterday. I was 6 and came home from school feeling feverish and out of it. My mom sat me on the toilet and proceeded to take my oral temp. I wasn't concentrating on the thermometer and it slipped out and broke on the floor. My mom came in and said looks like we are going to have to take your temperature in your hiney. At that time I freaked thinking it would hurt like a shot and ran to my bedroom and hid under the bed. She came into my room and said to get up from under the bed. I said no and she said if you don't come up from there I will spank you. I reluctantly came up and she asked me to pull down my PJ's and roll over on my tummy. I watched her very closely, I remember her holding a strange thermometer with a pearshaped tip. On it was a large gob of vaseline, so thick it had a peak on top of it. I had never seen anything like that. I said to her that my butt would spit it out and she proclamed that she would just put it back in. Then she proceeded to part my cheeks and that is when all the fun started. I felt the cold tip of the thermometer hit my anus, which made me tighten up, then proceed to go inside of me. It felt like a large rod being pushed into me. It was icy cold, very irritating (in a good way) with the stiff vaseline on it and felt every line of that thermometer as it dove deep into my butt, I guess it felt like 2-3 inches since it seemed never ending. I had shivers going all the way up my spine. she then said call me when I don't feel it any more that was about 3-5 minutes. She then proceeded to take it out. After the 2-3rd time I was hooked on the heiny variety thermometer with the pear shaped tip.
