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.
