The week has been busy for all parties involved.
Since Tony no longer wanted to take things slow, his transition continued full force. The nanite grafts extended his tail even more, and even more nanites were deposited into his ears, making them pointier and stimulating development of his ear muscles. He has received another dose of growth hormones, growing his cock to full 14 inches and giving his musculature a boost.
And, of course, there was a breeder session. Again Tony find himself in a VR chamber, in his eyes images of him with other ponies, sucking and fucking and being fucked. And in his ears, instead of a random lab technician's voice, was Max's voice. Telling Tony how proud he was to have such a great pony for a brother, how happy it made Max to see Tony a happy pony, how much he wants to see Tony's dreams come true.
Roger meanwhile was getting an accelerated pony transition. He received all the enhancements Tony had before, from artificial tail and mane to chestnut anti-sunburn, but he got even more growth hormones and implants. His cock grew to 10 inches long and very thick. With nanites, implants and hormones, his balls became big as baseballs and his body grew even taller than Tony and much thicker. While Tony was on his way to being lean and quick, Roger was becoming stronger and meatier, with fat deposits over his butt and lower belly to support his productive girth.
His breeder sessions were accompanied by voices of Max and Tony, telling him how much they adored him and how happy they both were to have him as Tony Farms' second pony.
And while his ponies were undergoing their treatments, Max was busy on the farm. He knew that in a week he'll get a pair of very sexually active ponies, so Tony Farms needed to be staffed and equipped to keep Tony and Roger healthy and busy. The lab provided him with a general pony doctor and a dietologist, and Max didn't want to get any new ponies, so he spent the week scouting for general farm help and purchasing equipment.
