Friday. The week-long refresher course at the medical school had finished at noon. I'd gathered my carry-on suitcase and rushed across the river , planning to spend a few hours at the newly opened university ethnic art museum. I'd reserved a seat on the last plane out to the coast , anticipating a leisurely stroll through the exhibits. The fall day was cool and clear. Some maples had started to display fall colors and glowed brilliantly against the blue sky.

The museum , a strikingly modern structure set on the periphery of the campus, contrasted sharply with the familiar Georgian college buildings. Few visitors were present. The only other person checking belongings was a tall attractive brunette, about thirty. We were both checking university-labeled tote bags. Mine was bulging with the course syllabus and a few medical texts I'd bought. She smiled and said "you've got your work cut out for you, I see. What course were you attending ?"

"The refresher course in interventional radiology. I come back every year to recharge my batteries and learn something new. This year's content was especially interesting."

"So you trained here?"

"Yes, in fact college, medical school, and most of my specialty training, all here. I must say I miss the place, even after all these years of living across the country. I gather you're connected with the university."

"I'm doing a postdoctoral year on a Fulbright. My field is Aztec iconography, sort of impractical but fascinating. A lot of kids are taking the course I'm teaching on the Indian civilizations of central and south America."

"Why don't we walk through the Aztec exhibition here and you can educate me. I know very little about these people except that their gods demanded human hearts and blood. That must have been rough on the neighbors! I'm Paul Collins. What's your name ?"

"I'm Ann Purcell. I got my degrees here, too. Yes, the Aztecs were tough on the neighborhood, but cruelty wasn't their purpose. Their mythology had their gods sacrificing themselves to create man, so offering human hearts to them was a kind of pay-back. And it ensured a good harvest. For better or worse, Cortez put an end to all of that and in the process enriched spain with melted-down Aztec gold."

As we walked through the exhibits Ann eagerly commented on what we were seeing. I began to feel a strong attraction to her. She must have felt something, too, for she soon put her arm through mine.

I suggested we go to lunch--several upscale restaurants had opened nearby since I was last here.

"Oh, that sounds lovely, but why don't we go to my place and I can show off my skills at making tuna sandwiches. I live just a few blocks away. Do you have time ?"

"In fact, my plane doesn't leave til eleven-thirty. I'd love to find out more about you over tuna sandwiches."

We retrieved our things from the checkroom and walked hand in hand towards her apartment. She started to squeeze my hand as we walked and talked. Her palm was getting moist and her voice took on the husky tone of sexual arousal. We were walking in close body contact, like lovers. As we approached her building she started to run, dragging me along.

In the elevator Ann threw her arms around me and drew me to her. Our mouths met and instantly her tongue was exploring mine. Ann ground her pelvis against my very erect penis. I reached behind her with both hands

And lifted her light tweed skirt. She was wearing no slip and clingy smooth panties. I slipped one hand inside her panties and followed her crevice down to her labia. My other hand followed her pubic hair til both my hands were stroking her very wet cunt. We arrived at her floor, luckily unobserved. Ann's hand was shaking so I took the key from her and we entered her small flat. We tore off each other's clothes and sank to the floor, entwined mouth to mouth. I took her small breasts in my hands and caressed her nipples, now hard and erect. I disengaged from her lips and sucked her nipples, while my hands parted her legs.

"Put your fingers in me, please !" Ann cried. I inserted two fingers of my right hand into her vagina, and with my thumb began to rub her clitoris. Ann was going wild, bucking her pelvis and devouring my tongue.

I reached down with my left hand and found her anus with my middle finger.

"Yes, yes, please stick your finger in me there, too. I love it ! Oh, you're making me feel like I'm flying!"

I inserted my finger into Ann's rectum and moved it in and out. Her excitement mounted.

"Now, do it now ! Come inside me, hard!"

I thrust my penis into her vagina. We pumped each other until we could hold back no longer, and we both came explosively.

We lay on the floor, very happy, very sated, for at least a half-hour of kissing and caressing each other's bodies, literally from head to toe. It was marvelous. This bright, attractive woman and I spontaneously and unexpectedly had come together by chance. Who could have predicted this ?

"I promised you lunch. Can you eat unclothed or must you be modest?" Ann laughed.

"I'll try to keep my mind on the sandwich, but I just may get distracted, and then who knows what an aroused art lover cum medical doctor might do ?"

"You're funny and very sexy. I loved what you did with your fingers. I didn't know until you entered me that my rectum could be the source of such intense sexual feeling. Have you ever done this before ?"

"Well, since we're being frank, and we're both adults, I can tell you that I have. In my experience--I'm several years older than you--most women are anally erotic, and many find this out like you did, when a sexual partner introduces them to that part of their sexuality. And for many, strange as it may sound, being given an enema is the height of anal pleasure. This really is no surprise.

"What about when you were grown up ? Have you given enemas to girls as part of sex?"

"Yes, I have. Being a doctor probably made it more acceptable for the girls, or women. There's no age limit to anal eroticism, almost invariably they would somehow steer the conversation to the fact that they were having trouble with constipation, and that laxatives either weren't working or would work at unpredictable or inconvenient times. And they'd ask my advice. And invariably I'd offer to give them an enema and show them how to do it safely, what positions to use, the quantity hot water and soap to use, and the different sizes and shapes of enema tips that were available, stressing that enemas should not be painful or unpleasant, but properly given, could be a source of sexual pleasure. The girls were invariably aroused by this talk and welcomed being given enemas, usually having sex while the enema filled them. I needn't tell you that I participated fully in this sexual scenario. And anal sex always followed after one or more enemas, usually because the girls wanted to see what it felt like. "

"Didn't Yeats write "love has pitched his mansion in the place of excrement?"

"He did indeed, in his poem "crazy Jane talks to the bishop." I wonder how much anal sex Yeats stimulated among college kids? Anatomically this phenomenon is understandable. The whole pelvic region shares the same set of nerves."

"Well, doctor, now you've gotten me sexually aroused and curious. Will you demonstrate? I do have an enema and douche bag. Let's go !"

Ann took me into her bathroom and produced the enema bag. I filled it with warm water and soapsuds and hung it on a hook behind the door.

"Ann, get down on your knees and rest your head in your arms on the floor. Tell me what you feel."

"You're rubbing Vaseline on my anus, and now you've inserted your finger in my rectum. I feel you spreading the Vaseline inside me. Now I feel you slipping the enema tube into me and now I feel the warm water entering me. Wow, it feels sensational. I haven't had an enema in years, and it was nothing like this. I'm getting very excited and very full. I'd like you to have sex with me while I'm getting the enema."

I slipped my very erect penis into her vagina. We pumped and pumped and came wonderfully together.

"That was incredible, Paul. I'd love to keep you and the enema tube in me but I need to sit on the toilet now."

Ann expelled her enema, joyously. Then she called me back into the bathroom and took my penis into her mouth, and sucked me dry. I gave her another enema, this time plain tap water and a little salt, to was out the irritating soap. After, we lay on her bed, music playing, and talked about our plans and luxuriated in each other's warmth and bodies. After an hour or so Ann turned onto her stomach and drew her knees under her, raising her lovely behind and spreading her legs.

"Well, Paul, it's time to complete your demonstration. I would like you to come in my rectum. Think you're up to a little anal intercourse ? You made it sound so appealing I'm anxious to find out for myself."

"With pleasure. But first I'll lick your cunt to get started, then enter your vagina for fun and lubrication, and before I come I promise I'll enter your rectum."

Ann and I did all of this. I don't know who was more grateful to the Aztecs for making this afternoon of lovemaking possible.

We met several more times over the next few years, repeating our lovemaking, all of it. Eventually we both married other people, but remain in touch to this day.
