Indulge a little, but think on the problem

Amber might be stuck now, but it wasn't like she was going to get worse; you figured you may as well let off a little steam before you worried about it any more. Still, one quick precaution before things got any weirder without your knowledge. "Serena, would you rather you can't give Amber any hypnotic suggestions without my permission, or have to say them loudly enough that I can hear them as well?"

Serena glanced up from Amber's udders to give you a slightly pouty look, but then bit her lower lip and mumbled, "I'd rather need permission," before she returned her attention to milking Amber.

You couldn't help but grin. "Yeah, you would."

You took a moment to simply watch the two of them, Amber stroking Serena's hair and mooing to herself while Serena let out happy-sounding little moans as she suckled from the newly made cowgirl. Weirdly, the scene was just as peaceful as it was hot, and you were content to let it go on for a while as you thought about what to do next. Between her cowbell, udder-displaying wardrobe, and frequently needed milkings, Amber's udders were now going to be a central point in her life no matter what. You couldn't change any of that, but you could make it so it was less of a burden for her.

Obviously, if you wanted to be as good about this as possible, you should involve her in these decisions...but honestly, that sounded like it would be a lot of extra work. She was understandably furious about all this (when she wasn't distracted by Serena suckling on her), and from what you'd seen of her temper, she was likely to be uncooperative to the point of self-destruction if you gave her the chance. And it's not like you were some kind of freaking saint, anyway, you just weren't out to ruin her life for no reason.

So, you could try to fix things carefully. If you precisely worded some 'rather' questions and used some subtle milking hypnosis, you were pretty sure you could get things back to a positive place for her. It might take a little while to work out the details, but if you were careful enough, you could make sure it all worked out okay.

Or on the other hand...

"Amber, would you rather you had naturally led a charmed happy life that somehow made you the way you are now and you could only faintly remember your life the way it was before, or let your past remain the same but from now on think all the changes I make to you as hot as they were upsetting and no one will **** you using them?"

Amber's eyes flicked to you and you saw her temper flare at you asking her another question, her udders visibly plumping up with more milk. She gave a loud moo, clutching Serena even more tightly to her as the milking got that much more intense. Her eyes screwed shut again as she moaned out, "Make them all hot!"

Instantly, Amber became a contradiction in terms as you saw her both obviously relax and get much more intense. Her movements turned less stiff but more energetic, obviously enjoying Serena's attentions more while the stress of the situation faded from her. The bell at her neck clanked as her back arched, and she shook her head, clanking it again on purpose. "MooooOOO", she moaned, the noise itself arousing her even further.

Serena sat up, taking a deep breath. She straddled Amber and cupped Ambers's udders with her hands, continuing to massage them gently. She looked over at you as Amber squirmed underneath her, a mischievous grin on her face. "Not exactly the most subtle solution, but it works for me!"

You grinned back. "Who has time for subtle?"

Standing, you walked over to the bed, dropping your boxers. You eyed the narrow dorm bed for a moment, then your brow cleared and you asked Serena, "Would you rather you had a giant fancy four-poster bed or that your whole dorm room was redesigned for sex?"

Serena surprised you a bit with her answer as she said, "A giant bed."

You found yourself losing your balance as the bed gently expanded outward, knocking your knees out from under you and making you sit down hard on the suddenly plush even as it pushed her desk and chair aside. You raised a questioning brow at Serena, who shrugged. "I dunno, I probably still want to finish school?"

Fair enough, you supposed. You glanced around the room, now almost entirely filled by the bed, then back at the girls, and rose to your knees. You put a hand on Serena's cheek and gently tilted her head down, noting with amusement the way her eyes practically dilated as they fell on your cock. You let her crawl off of Amber, who mooed in protest, and Serena happily flopped down to her back, her head to the side, mouth open and tongue eagerly out. You indulged her, thrusting forward into her amazing mouth, and she began to work her magic, her tongue and throat massaging your cock with impossible skill.

Amber sat up, and you grinned over at her. "Feeling better?"

She gave you a cautious smile, and opened her mouth to say something sarcastic, but all that came out was a plaintive "Moo!"

You couldn't help but chuckle, and reached out to tweak one of her nipples. She shuddered, reflexively thrusting her udder further toward your palm. You set up a couple of pillows and laid back onto one of them, Serena seamlessly shifting to all fours as she continued to suck, starting to bob her head. Gently, you slowly pulled at Amber's nipple, making her moo again and shuffle toward you on her knees. You tapped Serena on the head, saying, "Take your time, 'Bunny, it's been a long afternoon; let's all just relax a bit, alright?"

Obediently, she slowed herself, laying down onto your thigh and stopping her bobbing motions. Instead, she started slow, rippling ministrations with her tongue and cheeks and the occasional shift of her throat. It felt amazing, but wasn't really getting you close to cumming; the perfect cocksleeve.

While she got herself settled, you patted the bed next to you, indicating Amber should lay down. She did so, giving another little moo, and you turned her to her lean on her side so her udders were both up in your face. She got what you were looking for and leaned up on an elbow, cupping her udders to present them to your waiting mouth, and you happily went to it. Her sweet milk flowed into your mouth and you slipped an arm under her, pulling her soft body toward you as you suckled.

For the next while, the three of you all lay there in a calm, lazy, sexy pile. In the rare moments where your brain was working a little more, you reveled in how you'd personally changed both these beautiful girls to the point you were pretty sure they would stay here absolutely as long as you let them. Serena's perfect cock-sucking mouth was indulging in her favorite thing in the world, and milking Amber's magically full udders was sending the newly minted hucow to a place of perfectly pleasured and blissful contentment.

You weren't sure how long you stayed like that, but it was unquestionably the best afternoon you'd ever had. You might still feel a little bad about accidentally sticking Amber with these changes, but it was going to be real hard to stick to those kind of regrets if it led to moments like this.
