The next Sunday two tennis balls materialized in the Astarte Nunnery basilica, and a female body grew out of each.
One of them had black hair and eight E-cup breasts, the other blonde hair and just two breasts (of the same cup).
They bowed down before the (naked) people who were waiting for them -- the nuns, Jane and John - and introduced themselves.
The 8-titted woman said, "Hi. We are the conspecifics of Jane who have been invited to participate in a new research on human sexuality, and we thank you for your invitation and cooperation.
Jane has told us a lot of things about humans, but we may haven't learnt the most important ones, so feel free to reproach us if we behave tactlessly.
I've taken on the name of Hathor, my friend the name of Phryne. Hathor was one of the Egyptian versions of the Mother Goddess, and was depicted as a cow nursing the whole world; Phryne was a well-known Greek harlot, of so commanding beauty that by just undressing herself in front of a court of law she once escaped conviction for impiety.
Jane has asked us to separate feeding from sex, so I took the role of the wet nurse, Phryne the role of the 'sex-bomb in training'. I can be a good friend for each and every of you, but not a sex partner, because it won't fit my role.
Phryne has a lot to learn, not just about sex, but about practical wisdom as well -- so, please, don't take advantage of her. Jane will be her sex instructor and guardian -- and will allow you to give her supplementary lessons if she sees fit.
Now you have to do me a favor: all humans here must kiss me. Not a deep kiss, just a kiss on the lips, so I can assess your nutritional requirements and adapt my milk to it.
That's why I have eight mammae -- each of you will be allotted one, and you may nurse from it at breakfast, lunch or dinner. I don't yet know if nursing on request will be feasible.
You needn't worry about being overfed: my milk chemistry will automatically adjust to your bodily needs.
Who's going to kiss me first?"
Chang Lequ and Edna Rosenthal kissed Hathor first, then followed Antonia Soro and Tanya Gandhi, Greta Lilienblum and Mary Uhuru, Svetlana Ljapunova and Rivka Kernberg.
The first couple was assigned the upper left pair of mammae; the second one the upper right; the third couple the lower right pair, the last couple the lower left pair.
Then Hathor noticed John, who was watching the scene, covering his erect penis with his wife's buttocks.
"John, you haven't kissed me."
"Ms. Hathor, my wife Jane nurses me."
"Never tell a spring, 'I'll never drink your water'. John, don't be shy, come here, and I'll nourish you if need be."
Jane told John, "Kiss her. Don't worry, she isn't going to part us. She is just worried about your welfare, and she knows that you don't need just milk."
So John made Jane to rise on her feet, thus exposing his erect penis; all nuns fell silent, while Jane smirked, as if to say, "He is a human male; what else could he be supposed to do?"
John then stepped towards Hathor with a brisk gait, smiling and waving to the nuns, with the penis still erect. He didn't know how to approach the shapeshifter, but she grasped his hips, drew them to hers, slowly hugged him (so he felt his penis pressed against her belly, and her 8 nipples against his breast and belly), and then touched his lips with hers.
John couldn't help opening his mouth, and Hathor did the same -- but their tongues didn't cross, and the kiss remained a clinical test.
"You're an excellent partner for Jane," Hathor concluded, "I may only be your deputy nurse."
"That's OK for us, Hathor," John answered before hiding his penis behind his wife again.
Phryne then came to Jane and told her, "Ms. Jane, I suppose."
"Yes, I am. Here is my both oversexed and shy husband John. Please, get out of your hideout."
John did that and told Phryne, "Nice to meet you."
"Nice to meet you. Jane had told us that sex is very powerful among humans, but I haven't witnessed that until now. Thanks, John, for the lesson."
"You're welcome. What's your training program?"
"Jane says that she wants me to witness orgasms enjoyed both by humans and by ... her, in order to learn how to get aroused and to bring myself to orgasm, alone or with a partner.
When I'll be able to consistently reach orgasm with her, we'll start lots of experiments, in order to understand how having orgasms may affect our nature.
If we conclude that orgasms are positive experiences, I'll ask another shapeshifter to come and learn, with me and from me, before teaching all our conspecifics how to enjoy orgasm."
"How about Hathor?"
"She isn't just your web nurse, the one who will help you get over this economic crisis with her milk, but also the research director.
The way she kissed you was somewhat unexpected. Perhaps she likes you."
"Perhaps. But I like my wife better.
Jane, when will you begin to train Phryne?"
"Hmm ... I think that we can begin now. The first phase of her training is showing her how people like us have an orgasm, and we aren't allowed to have sex within the cloister."
So they hurriedly come home, at the porter's lodge, unrolled a big woolen rug, and bade Phryne sit on a corner with her legs crossed.
Then Jane sat on the center of the rug, leaning backwards and propping herself on her elbows, so John could kneel between her spread out legs, and kiss her twat, lick her labia, titillate her clitoris, while Jane's breasts enlarged, her areolas reddened, her nipples lengthened and hardened, and milk started gushing out.
Phryne too felt aroused: her bust size increased from 36E to 36G, her breast veins became engorged, the areolas enlarged, the nipples lengthened so much that they resembled little phalli; Jane took notice of these changes, but focused on the sensations John was giving her.
His tongue had made the clitoris erect, he suckled it as if it were a nipple, and meanwhile he inserted his right fore- and middle finger into her vagina, searching for the G-spot. As he found it, Jane writhed uncontrollably, squealing of pleasure, sprinkling milk all over the carpet and gushing ejaculate form her urethra into John's thirsty mouth.
Phryne too was affected: her nipples leaked fluid, and her vulva left on the rug an LP-sized stain. Jane grabbed John's head, thus signaling him that it was time to shift gear, so he seized her hips, straightened his legs, and inserted his penis into her vagina.
She hugged him, while he put his hands on her areolas and massaged them -- making milk leak out; as Jane's arousal grew, so grew her squeeze on John's penis. He throbbed, throbbed and throbbed until she came several times, and as he came, she kissed him in the mouth.
Phryne emulated John and Jane by inserting a finger into her vulva, and shouted -- because not only had she grown teeth in her mouth, but also in her cunt, and they bit her. But after the first bite, she gagged the cunt open with a hand, and penetrated it with another -- so she could experience an ersatz penetration.
John's and Jane's habit was to turn over after his orgasm, without loosening his penis, so she could sit on his pelvis, nailed by his penis, whose detumescence was prevented by the energetic massages applied by her vaginal muscles.
While waiting for another orgasm of his, they could hug, kiss, tell each other words of love, or Jane could let John play with her breasts at will, and suckle her milk.
But in that occasion Phryne interposed herself: while John was massaging Jane's areolae, and Jane was laughing with him, she walked on her knees towards John's head, spread her thighs open, raised her pussy over John's mouth, leaned forwards, grabbed Jane's elbows, touched her breasts (36I) with her own (36E), and neared her own mouth to Jane's.
Jane felt Phryne's nipples pressing on her breasts, additional arousal, removed John's hands from her own breasts, put them on Phryne's buttocks, told him, "Lick!" touched Phryine's lips with her own, opened the mouth and deeply kissed her, while John was able to lick Phryne into orgasm without being bitten.
Jane hugged Phryne and pressed her own nipples against her thighs, kissed her again, while John was able to lead her to orgasm again by eating her pussy.
"Would you like to change position?" Jane asked, and Phryne, as per Jane's directions, rose to her feet, walked past Jane, propped her legs against her back, bent forwards until her hands were on the rug, her mouth was close to John's and her breasts hanged over his breast and touched Jane's.
Jane grabbed Phryne's hips and lowered them down to her mouth's level, so she could eat her pussy, and John kiss her mouth and touch her nipples together with Jane's.
It was now Phryne's turn to uncontrollably wrythe, and to leak fluid from both the nipples and the urethra; when Jane decided that she had had enough, and it was now John's turn to come again, she politely asked Phryne to rise on her feet, and sit before John's head, if she wanted to watch husband and wife enjoying orgasm together after a long distressing day.
She did it, they enjoyed it, and even Phryne enjoyed orgasm by sympathy -- much in the way the strings of a piano resonate with the concert a nearby piano is playing.
When they were done, not just with sex, but also with cuddling, Jane reviewed Phryne's behavior and stains.
"Phryne, your emulation is imperfect. It is normal for a woman to enlarge her breasts when aroused, but an increase of two cup letters may only happen during pregnancy, and it will take about a quarter to become apparent.
Your nipples are too long, and they shouldn't leak saliva, but milk or colostrum.
Teeth are fit for the mouth only -- even though most women would like to have another set there, as the ultimate counter-rapist weapon.
Female ejaculate is not made up of milk, but resembles semen."
"Don't be too strict, Jane," John said, "You have often administered me milk through your urethra. In my opinion, in this case it depends on her and her partner's choice."
"Jane, I know everything about it. The problem is that I can't yet help muddling up the anatomical and physiological planes when I'm smitten with a strong emotion."
"You'll learn to correctly manage your body in a few days. Now it's time to join the lunch in the refectory."
