Slowly Clarisse settled into a routine. Breakfast in the morning, then lessons in the afternoon, milking later and then early to bed. Repeat the next day, with frequent trips to the doctor's and ample time for writing reports.
She slowly got used to the constant flirting that all bulls and hucows seemed to do. The rules were different here on the farm, with the physical transformations and hormones making what would be overly forward behavior in normal society just commonplace here. The bulls checked out her every chance they got - at breakfast, in the office, when they were walking around, shooting her meaningful looks and winks. She flushed a bit at their attention. They saw big hucow tits every day, but hers were most probably the biggest on the farm - another effect of the serum? She had just assumed all hucows were that big, but Maria was right...hers WERE pretty damn big. She even had to be careful she didn't bang into doors or cupboards with their increased size. It was a little hard to walk around sometimes!
But speaking of breasts...milking became the favorite part of her day. She would wake up each day looking forwards to the afternoon, where a big strong bull would put her teats into the pumps and usually also fuck her brains out. They didn't HAVE to have sex at each session, but more often than not they ended up doing that. As much as she wanted each session to stretch on forever, They couldn't spend too much time either - the had a schedule to keep!
Her research continued apace. She gave herself regular injections of the serum, and also kept close records on what changes they had produced in her body. So far everything was working as intended - her milk production was higher than an average hucow's, and it only looked to get better with time. Were her larger-than-average tits also related to those results? More research was needed. As to the other effect of the serum - easier pregnancies...well, she hadn't gotten to that yet. She still didn't even really want to think about it...
While she wasn't being milked or crunching numbers in her room, she lectured. She had had some experience with this back at the university - they didn't let anyone become a doctor without some practical teaching experience - but she had no idea how the farm folk would take to a very academic slant to what they knew as their daily activities. She knew she looked a bit obscene in the too-small doctor's coat they had provided (wasn't their fault, she was the only doctor-hucow on the farm!) Her breasts threatened to burst the seams on it, so she simply just left the top unbuttoned...the bulls in the audience weren't going to complain, that was for sure!
The staff proved to be eager learners. Hucows and bulls came from all walks of life, all with their own questions and ideas. She taught them all equally, and she learned from them as well - they had far more practical experience than her, for one thing. How and why the pumps worked in the way that they did, hucow physiology, bull and hucow mating cycles...the teaching tested her mentally even as the milking taxed her physically, so it was a very tired (but fulfilled!) Clarisse Evans that staggered back to her room at the end of each day.
A month became two, and then three. Clarisse got to know the other hucows and bulls on the farm - amiable Jason, always ready to help (or fuck...he had a nice curved cock that Clarisse loved to get inside her) brassy Daisy, loud but warm, reliable Kyle and the slightly aloof Li Hua. They were a friendly bunch, not at all intimidated by her academic credentials. She asked them to assist with her research and they had all agreed.
Clarisse couldn't have asked for more. Everything seemed to be going along swimmingly. But there was one thing she hadn't counted on...
Side effects.

IT started simply enough. One day she had awoken to find her pillows damp with milk. Her breasts had started leaking at night. Clarisse frowned as she stripped off the covers and dumped them into the laundry basket. A little light lactation was normal, but this was not.
Maybe she had made the serum too powerful? But the simulations tested out alright...with a slowly growing sense of dread, she made her way to the doctor's office. She'd need a second opinion.
It was the longest fifteen minutes of Clarisse Evans's life as she waited for the results of the tests that they ran on her. Finally, the doctor beckoned her into the office.
"Well, this is an interesting development, Doctor Evans. Turns out your hormone count is on the high side. That's probably what's causing the increased lactation."
"What does that mean?" She didn't mean to sound stupid, but this was an area that was out of her research, and she's wasn't too proud to admit it.
"We'll need to ask our lab techs. Come back in about half a day."
So for the rest of the day Clarisse went about her usual activities, trying (and failing) not to think about the lab results and what they would mean for her and her future. She had some help in the form of the bull who took her from behind roughly during her afternoon milking session...it was hard to think about anything much when a thick cock was inside her. But once that pleasant interlude was done, it was back to the doctor's office for the results of the scan.
"So, Doctor Evans. The bad news is that the serum seems to have combined with your hucow hormones to increase your milk production beyond what you initially anticipated. The good news is...the same."
Clarisse blinked. The good and bad news were...the same thing. It sort of made sense. You could have too much of a good thing, and she definitely didn't want to be leaking milk all over the place. It would have to be controlled somehow.
"But how will that be regulated?" No harm in asking.
"I'm glad you asked." replied the doctor. You'll need another piercing."
"Another?" Clarisse looked down at the bits of metal hanging from her nipples. She didn't have three breasts. Where would the third go?
The doctor looked down at his papers a bit uncomfortably. "Yes. Another. Ummm. Yes. It will have to go...ummm...well...below."
