At 12:00 Jane served them a good meal, and persuaded Veronica to offer her tits to her and her husband, even though they were dry, before joining another threesome. But in this threesome, Jane and Veronica were having a 69 - Veronica below, Jane above, so John could penetrate her pussy and her ass without bothering Veronica.
At 15:00 Jane gave Veronica a practical demonstration of "tribadism": she laid supine, asked John to let his dick into her mouth, and Veronica to grind her vulva over Jane's Mons Veneris, in order to stimulate the clitorides of both. As Veronica wasn't very experienced and lacked coordination, Jane grasped her hips and twisted them over her mound while Veronica hugged John, and he enjoyed the blowjob.
At 18:00 John claimed he wasn't hungry, while Veronica was. So Jane had John impale her while she was nourishing Veronica -- and Veronica was grinding her mound against Jane's.
At 21:00 the next 69 featured Jane below and Veronica above -- so she couldn't help have John's genitalia in full view while she was clitorally stimulating Jane, and John was penetrating her. John was also moving his hands from Jane's breasts to Veronica's -- the latter didn't protest, as she was already acquainted at the contact between her breasts and his body.
At 22:00, they were too tired to continue working, and went to bed. In a nearby room there was a king size bed, and they managed to sleep all together, with Jane between John and Veronica.
Jane was supposed to nurse and copulate with them separately during the night, but seeing Jane having sex with John was really exciting for Veronica, and seeing Jane making love with Veronica was really exciting for John, so they had to arrange something different.
Eventually, whenever one of her mates wanted her milk, Jane aroused the other so (s)he could get his/her ration; after nursing, the one who took the initiative was allowed to have frontal sex, while the other could have rear sex -- by rubbing her vulva against Jane's buttocks or tailbone, or by penetrating her anus or vagina from the rear.
Jane, the nonhuman, could dispense with sleep, but it was not John's and Veronica's case, and they eventually fell asleep while hugging Jane, with her nipples in their mouths, like young chimps.
At dawn, Veronica saw John sodomizing Jane; they twisted and laid on their right side; Jane stretched her arms to her, and Veronica hugged her. She kissed her first, and then kissed John. When they were done, she asked Jane if John could do the same to her.
"After his refractory period," Jane answered, "He will do whatever pleases you."
After an hour, John was ready, Veronica hugged Jane and begged her, "Please, anesthetize me somewhat while his big dick gets up my ass."
Jane hugged Veronica, put her own nipples into her mouth, so she could solace herself with her milk, opened her buttocks and bade John to lubricate it. John slowly but effectively did that and eventually penetrated her.
Veronica let Jane's nipples fall out of her mouth, as she wanted to fully feel the sensations of sodomy -- which slowly turned from pain into pleasure; no small contribution was given by her grinding her own mound over Jane's, and by her kisses.
While doing that, John was squeezing Veronica's nipples, and Jane took advantage of it by inserting her own among her husband's fingers -- so John squeezed the nipples of both at the same time.
Veronica's pleasure tapered out before John could come; and Jane told him to get out before Veronica's sensations would become painful.
John's penis was still erect, even after washing it thoroughly, and Jane volunteered to take it into her own body, but Veronica claimed preemption rights, so John penetrated her vagina too -- and Jane humped her tailbone to have an orgasm anyway.
Veronica was now a bisexual member of the threesome, and at 09:00 they organized it somewhat differently.
John laid on his right side, Veronica on her left; he hugged and kissed her, fondled her tits and penetrated her vagina; as he was in her, Jane sat before them and let them use her thighs as pillows; she then dangled her breasts over their mouths, they caught her nipples, and while making love they suckled her milk and stimulated her vulva with a hand each.
When they were replete, and Veronica had had her orgasm(s), John would get out of her vagina, Veronica would lay procumbent on the supine Jane, and John would sodomize her.
After that, it was Veronica's turn to offer her tits to a couple making love [John and Jane] before letting Jane rub her own mound against hers, while John was sodomizing her.
It became the standard practice, repeated every three hours, until the software was completely installed, the legacy data converted and backed up in their pristine and current form, and the tax return filed on Friday -- three days before Monday's deadline.
Everybody was completely satisfied -- albeit for different reasons -- and Chang Lequ, the Astarte Nunnery abbess, allowed Veronica to live together with John and Jane, in the janitors' house.
