The doctor smiled at Daddy. "Her vaginal tone is excellent," he said, pulling his finger out slowly. "I think we can proceed to the anal & rectal without further ado. Doctor MacKenzie, will you get the labial spreaders?"

Doctor MacKenzie let go of my lips and pulled a strange-looking thing out of a drawer. It was four straps with four padded clamps. The doctors all came over, and the three of them put my outer lips between them, running each strap around my thighs. The first doctor stepped back and admired their handiwork. "There. Now you're all nice and exposed, and we can masturbate you easily. Isn't that nice?"

"Yes, Doctor," I managed. I was humiliated and thrilled.

"Good, good. Doctor Jones?"

Doctor Jones stepped up with a thermometer in his hand. It was bigger than what Daddy usually used. He was lubricating it with some gel. "I'll need your Daddy to show us how he takes your temperature," he said, smiling at me. "Mr. Black?" he said.

Daddy got up and came over to me. I relaxed a little; I loved it when Daddy took my temperature, though I was usually over his lap when he did it. He explained his procedure to the doctors. "First, I lubricate and massage her anus..." Daddy rubbed my hiney-hole, pushing a little. "If she seems especially tight, I rub her clitoris with my free hand." To my horror, he showed them how he did that as they watched intently. "Then I press the tip of the thermometer to her anus, and press it in very slowly." I gasped; while it wasn't huge, this thermometer was still bigger than what I was used to. Doctor Jones noticed and said, "This is a veterinary thermometer, and it is bigger. You need to become more accustomed to larger objects penetrating you."

"Yes, Doctor," I whispered again.

"While it's in, I make sure to rotate it and move it in and out a little, and I masturbate her a little." Daddy's finger was on my clit, and I moaned. "Once it's been in long enough, I take it our and bring her to orgasm immediately. Then.." Daddy looked at me expectantly.

"Thank you, Daddy, for taking my temperature and making me come," I replied, the same way I always did. He beamed and patted my thigh.

Doctor Jones nodded. "Excellent procedure, Mr. Black. And after this, you begin anal play?"

"Sometimes," Daddy said.

"May I please see what you usually use?" Daddy pulled a bag I hadn't seen from under his chair. All the toys he usually used on my hiney-hole were there.

"Well," Doctor Jones said to me, "there are quite a few toys here, young lady. Do you like it when Daddy plays with your anus, when he makes it all nice and wet and pushes things into it?"

"Yes," I whimpered, ashamed but also unbearably aroused.

"That's a good girl," he soothed. "I'm going to start exploring you now." He sat on the little stool. "If anything hurts, you must tell me. Your Daddy wants this to feel good so that you will look forward to it. You want your Daddy to be able to use your anus, don't you?"

"Yes," I said, crying a little. I wanted Daddy to be able to put his cock in my hiney-hole more than anything, but it always hurt so much that he'd stop. I was so embarassed that theses strangers knew this.

"Good," he said. "I'm just going to rub your anus for a while." His slick finger, so smooth in the glove, began rubbing my hiney-hole. It made me squirm, and he started pressing it in a little. As he pushed his finger into me, he reached up and rubbed my clit with his other hand. "Good girl," he murmured. He started moving his finger in big circles, gently stretching my hiney-hole. I moaned and tried not to move. After a minute of this, he stopped rubbing my clit and slid his finger out. "Mr. Black, what size toy do you usually use first?"

"This one," Daddy said, holding up a small black buttplug. The doctor nodded. "I think our patient is aroused enough that we can go a step up." Daddy agreed and handed him the next bigger plug.

"I'm going to push this into you very slowly," Doctor Jones told me. "I'll be masturbating you, and I'll need you to tell me when to put more in."

"Yes, Doctor," I said. He lubricated the plug and put the tip against my hiney-hole, and then started rubbing my clit again. I felt the tip slide into me a little. "Would you like more?"

"Please...please put more in my hiney-hole," I begged. It felt so good, and his finger on my clit was almost as good as Daddy's. He pushed more in.

"It feels good when the toy stretches your anus like this, doesn't it?"

"Yes," I gasped. I was so close; "Can I come, Doctor?"

"You can come when the plug is fully inserted." He twisted it a little. "Should I put it all the way in?"

"God, yes, please, put it in me..."

"You'd like me to fill your anus with the plug?" he teased?

"Yes! Yes!" As he pushed it home, I came, screaming again. When I stopped, the plug was still in me. "Very good," Doctor Jones said. "I think you're ready for something much bigger already. Mr. Black, can you show me a toy one size smaller than your penis, please?"

This always made me excited, because if I could fit the toy that was close to Daddy's cock size, I'd surely be able to fit him in my hiney-hole. It just never seemed to work. The doctor gently pulled the plug out of me, and settled in to put the new one in.

"Doctor MacKenzie," he said as he greased up the new plug, "can you get the vibrator and place it for clitoral stimulation?"

"Of course, Doctor," he said, getting a bullet-type vibrator out of a drawer. He somehow attached it to the harness that was holding my lips open, put it on my clit, and turned it on. I gave a little shriek, though it felt good. It was so intense!

"Same thing," Doctor Jones said as he put the plug's tip in my hiney-hole. "You can orgasm when you take the whole plug in your anus."

It seemed to take forever, he pushed it in me so slowly. I was being stretched and spread and could feel every bit of the plug. I wanted to come so badly. "Please, please," I begged.

" 'Please' what?" he sing-songed?

"Please shove it up my hiney-hole!"

He did, and as the plug popped all the way inside me, I came so hard I saw stars. I came until I thought I'd pass out. I closed my eyes; the vibrator stopped, and the plug was pulled out as slowly as it had gone in.

Doctor Jones turned to Daddy. "She clearly enjoys this," he said. "I think perhaps one more exam is in order, and then we can proceed to the inflatable, and then attempt penetration."

Daddy nodded, stood up and took off his clothes. I was confused; surely they weren't going to do something to Daddy? The doctors and I noticed his erect cock at the same time, but they all chuckled.

"Our Daddies never have problems with this part of the exam," the first doctor said. "Now, little girl, we'll help you up while your Daddy lays down." Baffled but not caring much, I let Doctors Jones and MacKenzie get me off of and stand next to the table.

The first doctor turned to me. "You see, I will need to examine your anus while your Daddy penetrates you vaginally. You will mount your Daddy, insert his penis, and lean forward. All three of us will lubricate our fingers and examine your anus while he penetrates you. You need not ask permission to orgasm."

This was even worse. Daddy usually let people watch him fuck me when he wanted to punish me. "Daddy," I whimpered, "please, no."

He held out a hand. "It's not punishment," he said. "But the doctors have to examine you this way. Besides," he grinned, you like having things in your hiney-hole while Daddy fucks your pussy, don't you? Tell the doctors."

I turned to them, but couldn't look at them. "I like it when Daddy fucks my pussy when there's something up my hiney-hole," I admitted.

"There's nothing wrong with that," Doctor Jones said. "It's normal for little girls to like things in all their orifices." He helped me up on the table. I took Daddy's cock in my hand and pressed the head against my pussy, and started sliding him in the way I knew he liked. Once he was all the way in, Doctor Jones bent me forward and started rubbing my hiney-hole again.

"Oh, my - your anus is very soft. I can push my finger right in.." he said, and did so. The other two doctors stood at my head and asked me questions while Doctor Jones moved his finger in my hiney-hole. I closed my eyes and answered; did I like feeling all my holes filled? Did I want the doctor to put another one in? Did I like feeling his finger gliding over Daddy's cock? The answer was always yes, and then I came again.

"Excellent," Doctor Jones said as he eased out of me. "Two fingers, Doctors." I was slumped on Daddy's chest, beyond doing anything but getting fucked and probed and answering whatever they asked me. Doctor Mackenzie was next, and he slid two fingers into my hiney-hole easily but quickly. I gasped and squirmed. "Please," I begged again. "More, put more fingers in my hiney-hole."

A murmur of approval went around, and I was rewarded by three fingers stretching my hiney-hole. "Go ahead," he urged. "When you orgasm, it makes your Daddy's penis feel good." That was all it took to make me come again, my hiney-hole spasming around the doctor's fingers and my pussy gripping Daddy's cock.

The first doctor was ready. "This will be a little different," he explained as he massaged my hiney-hole. "I'll explore and examine your anus with my fingers, but I'll also be putting a vibrator inside you."

I moaned. "Daddy..."

"Yes, little girl," he said. "It'll probably make Daddy come. You want that, don't you?"

"Oh, yes, Daddy."

"That's my good girl."

The doctor got three fingers inside me so easily, I didn't realize it until he told me he was already in. Then he moved, spreading his fingers, stroking in and out of my hiney-hole. "That's it," he said. "Can you feel how I'm also touching your Daddy's penis? There's the head..." I came again, but they ignored that this time. I could hardly tell when he pulled his fingers out, though I gasped a little when the vibrator touched my hiney-hole. "Yes, it's a little bigger. But you want me to stretch your anus and make it feel good, don't you?"

I was beyond shame. "Yes, doctor. Please put it in my hiney-hole."

"Good, good girl," he said, and pushed it in. It didn't hurt, but it was bigger. Then he turned it on, and it made me come again. "Tell me how it feels," Daddy insisted.

"Daddy..it feels so good...I'm all full, all my holes are full, I like how I feel all stretched open, I like the doctors watching, I love the way your cock feels against the vibrator..." I lost control and came, with Daddy coming a few seconds after. The doctors gave us a few minutes to recover, then helped me get off Daddy and back on the table on my back again. Everything was a blur, and I didn't care about anything except having things up my holes and coming.

My clit was being massaged again, very slowly. Doctor Jones held up a black inflatable dildo. "It's time to make you ready for Daddy," he said, and moved back between my legs again.
