Favourite fantasy setting for rectal temperatures?

What is your favourite fantasy setting for rectal temperatures? In a healthcare or domestic setting?

For me, it's a domestic setting:

Domestic, of course.

On the sofa, over the knee of the girl who takes my temperature

In a clinical setting, a surprise instruction from a nurse to lower my pants and lay facedown on the exam table.

I've posted before. My colonic therapist (female) takes my RT before and after therapy. My fantasy has come true.

Having a strong rectal temperature fetish, my fantasies might be a bit unrealistic.

In a medical setting, the attractive female doctor wants to see how my couple performs when having sex. So, when I penetrate my girlfriend on her examination table, she inserts a thermometer in my rectum to record my temperature.

In a domestic setting, I imagine a threesome sex session with two girls alternating sex with me and taking my rectal temperature when fucking.

I think a domestic setting would be my preferred rectal temperature scenario because it would certainly lead to a very kinky conclusion. The next best would probably be in a medfet facility were I have less control over the situation and am at the mercy of a kinky/sexy nurse or doctor. My least favorite would likely be in a real clinical environment due the fact that in today’s practice, if an adult requires a rectal temperature, it is likely a very serious matter.

Domestic setting over the knee before during and after a spanking for ultimate humiliation.

I like the domestic setting where someone may be coming down with the flu. The oral thermometer is either low battery or misplaced, so unexpected that it will be taken rectally. Temperature is definitely taken over the lap and every two hours as the temperature is nearly 102F. A soothing bun rub is administered to the bare bottom being penetrated.The patient is cared for all day, with toast and tea and medicine to reduce the fever as the fever persists. First thing next morning the patient is over the lap for another temperature check(with bun rub of course). The fever is slightly lower but still high and the process continues like the previous day. Around midday the caregiver begins to feel a little under the weather and warm to the touch. The original patient turns caregiver and despite not feeling well, delivers a rectal thermometer to a bare upturned bottom. With fever present the two care for each other all day with over the knee temperatures , bun rubs , tea , toast and flu medicine.

My favorite fantasy is to be in a medical clinic where an attractive female nurse calls me into the exam room and has me take off my clothes and put on a gown, open in the back and allow me to keep my underwear and socks on. She would check my vitals and have me lay down on the exam table. SHe would pick up a glass rectal thermometer shake it and dip it in a jar of vaseline. She would motion toward me and order me to lay on my belly and of course, I would comply. I feel the elastic waistband of my underwear ride over my rear end and then the cool sensation of the rectal thermometer as it is inserted into my rear end. The nurse would tell me to hold still like a good little boy while the thermometer is in place for 5 minutes. She might comment on how good a boy I am and how I don't cry or complain like her other patients do. I might respond by letting her know I understand the dr. wants me to get better and if this part of what she (the Dr.) needs to make that happen, then I will comply fully. At that point, the nurse might wryly smile and say that I might secretly like when she takes my temperature this way and of course, I would not argue with her. Once the 5 minutes is up, The nurse removes the thermometer, cleaning off the vaseline and letting me know I have a low grade fever, letting the Dr. know and what other painful or uncomfortable procedures await me. I feel my undies go back up and once the dr. examines me she tells the nurse what will be next......
