"It's a lot nicer if you keep it short and trimmed - but, we have other things to take care of," Sue said. "In the stirrups", she giggled, as she grabbed my feet and raised them off the bed. My legs spread and I reached behind my knees to hold them up.

"Hey, if you're gonna take my temperature, shouldn't I be on my side or my stomach?", I asked, feeling the air across my pubis. My buttocks had also spread and I could feel coolness in between. Almost instantaneously, I was also feeling the warmth spreading over me as I had felt so many times before in the stirrups.

"Nah, don't you want to know what I feel?", Sue responded - and before I had a chance to answer, I felt her finger between my buttocks and then I felt the cool KY jelly and her finger pressing against my asshole. I tightened up a bit and Sue said, "See? Now, exhale and let me get you lubed up."

Sue's finger slid in easily when I exhaled and she had inserted it to about the first knuckle before she turned it around. My asshole tightened on her finger when she did this and as she began to withdraw it. She stopped and said, "Feel good?"

"Yeah - real nice," I said and I wasn't lying. I pulled back on my legs and pushed down so that Sue's whole finger was inside my asshole!

"Hey! You're the one who said you wouldn't like this," Sue said as she moved her finger in and out of my asshole. "Let's get that temperature taken", she said as she steadily removed her finger. I instantly felt a void as I watched Sue lubricate the thermometer.

"See - you can't do that quite as well to yourself", she said, and then she placed the tip of the lubricated thermometer against my asshole. The involuntary response occurred and then I remembered to exhale, as Sue slid the thermometer inside. What a strange feeling - no pressure because it wasn't wide, and it's not long enough to go deep, so it is just sort of an in between sensation....a light feeling that does cause a tingling.

When the thermometer was inserted, Sue stood up and said, "Now all you have to do is wait for four minutes."

"Do I have to keep my legs up like this?", I asked.

"Just go ahead and rest your feet on the bed, but keep your knees up and your legs slightly spread - it keeps the thermometer where I put it," she replied.

I lowered my feet to the bed and lay there as the thermometer peeked from between my buttocks - my knees raised and my legs spread. Is this an obscene or erotic position?

"I'm going to the bathroom. You just lie there and I'll be back before it's time," Sue said as she took her washcloth and a fresh tampon with her. When the door closed, I immediately had to do something - The cool air from the waist down, the stimulation caused by Sue's finger, this exposed position, the thermometer suspended in my asshole...

My hands came up and my fingertips lightly traced a pattern across my belly - then up under my t-shirt to my breasts. My nipples were hard and my hips were starting to move. I let my hands wander down to my bush, into the hair. Sue was right; it did need to be trimmed. Lower until my finger found my clit. I rubbed it and when I did I felt my pussy contract AND my asshole squeezed the thermometer. This was wild. I did it again - same wonderful response. I pressed my whole hand against my pussy - my fingers on either side of the lips and the palm of my hand rubbing circles on my clit. My hips were gyrating and I could feel the muscles and nerve endings in my asshole sensing the thermometer. I heard the doorknob turn! I quickly put my hands at my side and tried to shallow my breathing and keep my hips still as Sue came back.

She opened the door and put her washcloth on the rack. Then she came over and sat back down on the bed. I felt her hand on the underside of my thigh so I raised my legs to the "stirrups" position. I could feel her grab the thermometer but she didn't remove it.

"Is it hot in here? You're perspiring", she asked. Damn. I knew she could feel the perspiration on my thighs - I had gotten turned on that quick! Then she started twirling the thermometer inside my ass. "Can you reach down here and do this?", she asked.

I took one hand from behind my knee and reached for the thermometer. Sue removed her hand and I put two fingers on the tip of the thermometer. "Just twist it between your fingers," she said.

I did like she said and this was starting to arouse me. "You can also move it in and out," she directed.

Again, I did as she said, twirling it and moving it in and out. I could no longer hide my arousal as my hips began to gyrate.

"You wanted to know what I did, right?", Sue asked.

All I could was mutter an "Uh-huh" at this point. I was moving the thermometer all around in my asshole and really getting turned on by it.

Sue was still sitting on the bed next to me but her weight had caused me to move towards her so that my hip was against her thigh.

"You still have another hand," she said, as she took my hand from under my knee and put it directly on my clit. "Go ahead - you're really getting wet...enjoy yourself..."

I was too far gone or into it to worry about being exposed in front of my roommate, to worry about masturbating in front of her, to worry about getting off because a thermometer was in my ass! Yes, I was wet! Two of my fingers slid into my pussy with no problem. I pushed them deep inside and pressed the base of my hand against my clit. I kept pushing them into my pussy and pressing against my clit as I worked the thermometer in my ass. Sue raised my t-shirt above my breasts and moved her fingertips back and forth across my nipples and down to my belly. This was it! I made a few final thrusts with my hips and felt my insides spasm - my pussy gripping my fingers and my asshole gripping the thermometer. Sue lightly pinched my nipples as she sensed the peak of my orgasm. I remained in a position where my hips were raised, my fingers were deep into my pussy and my hand was pressed against my clit - the only thing that was moving was the thermometer in my ass, even Sue had held a steady but light pinching pressure on my nipples. This kept me stimulated as my orgasm plateaued. Then, I lowered my hips, removed the fingers from my pussy, and let go of the thermometer. I lay spread-eagled on the bed except for my raised knees. I felt Sue's hand on my buttocks and then her fingers between them reaching for the thermometer which had been inserted a little further during my orgasm. It felt good as it slid out and I was still winding down from my massive orgasm.

I awoke three hours later, in the same position except the covers were pulled over me. When I got up, my t-shirt dropped to mid-thigh but I could still feel a sensation between my buttocks. I reached around and found that there was still a slickness from the KY jelly, or was it the orgasm, or both? On the desk was a note from Sue:

Dear Katie - Your rectal temperature was 99.3, but I think it's a bit high because you were excited. That's OK. Do you want to take it again tomorrow? And, remember, I can help you clean up the hair, too! Sue

This was going to be an interesting semester. I grabbed my shower stuff and headed toward the bathroom...
