She hesitated in her fucking for a moment as it slid in, then I felt her sphincter relax and I stroked inside her anus as she slid her hot cunt up and down the length of my stiff cock. I withdrew my finger and applied saliva to two fingers of my right hand, and returned them to her rectum.
A small "Ouch!" and they were in. I kept punching, and when they were both clear in, I could feel the long shaft of my cock through the thin membrane separating her cunt from her asshole. I pushed my cock clear in and held her up tight against the end of the table, then began massaging my cock with my fingers. The intervening wall felt as thin as a cockrubber, and I knew that all her nerve endings were getting stimulated, both fore and aft. Her sharp intake of breath when I rammed it clear in at this angle told me that she was stuffed full and overflowing with meat, and the squirming that was starting to move her body told me that she was enjoying the tactile thrill that accompanies having both the cunt and anus satisfied. Then I held my fingers still and stiff, clear in, while I very slowly and gently let my cock slide in and out a few inches. Then I spread my fingers and flipped them rapidly as I really reamed her tiny cunt with my tool. In no time I could feel her extreme arousal, and hear it, too.
"Oh, Keeee-rist! Daddy, what're you doin'? Don't stop, whatever it is. My God, it feels like I'm on fire, front and back, oh, yes, oh, yes, do it more. Oh, there, there, there!" She almost screamed as another orgasm racked her young body and left her lying limp and face down on the table.
I took this opportunity to glance over my shoulder at the sliding partition. Wilson had it open and was almost drooling at the sight. I'd have bet he was jacking off in my office while we were fucking in the examining room. I went back to my work. Work? Hah! My heaven.
"Like that, Linda?" I asked.
"You know it, Doc. Jeez, I'd never had anything in the back door before. I'd always heard just the queers used that. But oh, boy, it sure tickled, and, God, it felt like my ass and my cunt were all one – just sorta melted and all run together, I couldn't tell where it was the best. Boy, you sure know variety, Doc, but I guess I asked for it," she said.
"Well, Linda, how would you like to really have a ball. Some real variety?" I asked.
"Just name it, boss!" she replied. "With you. I'll try anything. You're the doc." She laughed at her own pun.
"Okay, honey. I'm going to put it in your anus. It'll hurt some the first time – same as when you lost your hymen, or cherry, but I guarantee you'll love it. Are you game, angel?"
"I don't know, Doc. Goddam, that's awful big. But we can try. Don't hurt me too much. But that sure did tickle when you were in there before."
I bent her over the table face down and played with her cunt until it was juicy and slick again. I dipped two fingers into her box and slid them slowly up her rectum. I admonished her to relax, let her muscles go, and then inserted a couple of fingers from my left hand into her hot and melting cunt. The four fingers stroked and rubbed each other through the flexible membrane between the two cavities, and I could feel her body respond to this erotic stimulation. Her hand had reached around behind her butt so she could grasp my tool, and the feeling of all that muscle in her hand encouraged her to get hotter and hotter. As I increased the tempo of my strokes with my fingers, her hips and body were responding and weaving and writhing against my petting hands. I withdrew my fingers from both orifices and my cock from her hand.
I nudged the head of my cock against the pitifully tiny rosebud entrance to her rectum and rubbed it lightly there a couple of times. "Ooh, that tickles," she laughed. My mouth was practically drooling at the sight of those firm round young asscheeks staring me in the face, so I very liberally lubricated my cock with saliva and guided it with my right hand to the little entrance that was to be pierced. My left hand steadied her ass as I rubbed my slick spit up and down the crack of her little ass. "Now, relax, honey," I told her. "I'll just put one inch in, then we'll rest, then a little more. I won't hurt you any more than I can avoid, believe me."
"I trust you," she said.
I rubbed the knob several times against the entrance, then pushed gently but firmly. It wouldn't penetrate one millimeter. I told her to relax, and slid a finger in and stroked rapidly. As I felt her taut muscles loosen, I then suddenly switched cock for finger and jammed about three inches of cock into her before her sphincter muscles grabbed and halted my entry. The excruciatingly tight grip actually prevented my going either forward or backward. She looked over her shoulder and tears were in her eyes.
"God Almighty, Doc, you're tearing me in two. Take it out. I can't take it that way – you're too big. Doc, honest, I can't. Please don't hurt me any more. I'll suck you off, or fuck you to death, but you're killing me this way. Please."
I stood perfectly still. Then I stroked her body, being very careful not to move my tool at all. "Now, relax, Linda, you've already had the worst. The diameter is what gets you – it doesn't matter how far in it goes. It isn't like your cunt, that has a top end. Hell, you can take a foot and a half of cock up the ass, once you get used to the spread of your ass muscles. Just relax, and I promise not to put another inch in until you say so. You didn't give up this quick when you got fucked the first time, I bet." I felt her tight ring of muscle slowly loosen its grasp upon my tumescent cock. "That's it, honey. Now if it hurts just a little too much, say so, and I'll stop. I am going to pull it out an inch, push it in two inches, out an inch, in two more inches, and you'll see, and you will find out, that you'll love it. Trust me."
"It doesn't hurt so much, now I'm relaxed," she conceded. "I'll try. Just go real slow, and stop if I holler, won't you?"
"Sure, honey. Hell, I want you to learn to like it, and I'm sure you will. It's just that you're losing your ass-cherry. I'll be as gentle as possible," I told her.
I withdrew an inch and felt her spasm of tightening, and then I stopped and felt her relax again. I slowly shoved a couple of inches further into her, and felt her sphincter grab again. I stopped. It was all I could do to stop, to keep from ramming every mother-loving inch of my hard cock into her virginal anus and really rape this tiny asshole of this young maiden. But I held off, applied a little more saliva to my shaft, and eased another couple inches into her. Whenever I stopped, I could feel that tight ring relax, and then I'd slip another inch or two into her, until I felt the grab around my shaft.
By now I had about two-thirds of my ten-plus inches in her, and felt she was ready for some fucking. As I withdrew it almost to the hilt and head, I felt the vibration of her responsive body, and knew that the sensitive nerves of her ass were being tickled. I slowly but steadily pushed my cock its entire length into the tiny orifice and heard her sharp intake of breath as she absorbed the full impact of it. Once it was all the way in, I reached around in front of her and gently searched for and found the pink button that was standing so eagerly at the top of her young cunt. I rubbed her clit gently while holding my tool all the way in her ass, and felt her slow response. I withdrew my cock to the head and plunged in again, a little faster and harder, all the while massaging her clit with one hand and kneading a firm, full handful of tit with the other.
"Oooohhh, that's good, Daddy-Doc, oh, yes, oooppps!" [As I pushed it in to the hilt again.] "Yes, that tickles, oh, that feels so good, yes, do it, do it, stuff me clear full of ooooohhhhh, God, that's a lot of cock, Doc. But it's getting better, and I can feel it clear up inside my gut. Jee-suss! It feels like you're comin' out my throat," she moaned.
