Zen rushes over to the two of you, and before either of you can say anything, she asks, "Is she going back to the house with us?"
"Yeah, if you agree," you say, while Mino stutters out an apology. Zen puts one of her delicate, commanding fingers on Mino's mouth, and says, "Hush. I'll forgive you if you let me do you up."
"Wha?" Mino says, confused, before following behind you two. Zen bends down, and whispers in your ear, "First date and you're already bringing in a third person? My, you are perfect!"
"Yep!" you exclaim, grabbing her bags and putting it in your closet using your ring. You give Mino her own Biffa card, and you make your way back to the Cungadero.
"Woah, is this yer place, miss?" Mino asks, looking around.
"Yep. It's now your place too, you know. Your bedroom's up the stairs and to the right."
"There's no door on the right?" Zen asks, before she says, "Oh, wait, I forgot."
"Yep. Want me to make another new room for your hobby?" you ask sweetly. At your girlfriend's nod, a new room appears, stocked with all the amenities a spa could want. A second later, Mino comes down, wringing her hands. "Ah-Ah'm sorry," She stutters, "But Ah can't accept this!"
"You can and you will~" Zen threatens, "Now get in that room, and take your clothes off. I'm going to practice my new tools on you in a bit, just have to talk with my girlfriend."
At the mention of 'girlfriend,' you look up from examining the package. "Yes, honey?" you say, "Is something wrong?"
"I have a bit of an odd question. Could you grow a snake tail for me? Like a Lamia." She asks, before explaining, "I have some things in there that can clean up scales, and I want to use all of it."
"Of course, give me a moment, though." That's all you can say before a 'Crack' rings out from her new room.
"Ah'm sorry, my buttons just gave out!" Mino says, "Nothin' seems ta be broken, though."
"Go ahead, get started, I'll take a bit."
A quick kiss later, Zen has gone to settle Mino in, and you start transforming. Your legs start fusing together, and your panties shift out of the way. The resulting blob starts expanding, becoming easily 50 feet long. Scales start to grow underneath your skin, which starts falling off in layers, luckily fading away before hitting the floor. Your strawberry pink scales are flawless. 'This won't do,' you think, and start magically dirtying it, a few patches of every type of dirt Zen has a tool for removing. You slither into the room, to Mino and Zenaiya's confusions.
"What? Where'd the tail come from?" Mino asks, sitting on a leather salon chair in the nude. The poor tattered remains of her overalls rest on the floor.
"Why is it so dirty?" Zen asks, before it hits her. "Aww, you sweetheart. Take your clothes off and go sit next to Mino."
Doing as she asks, you take off your blouse, your bra, and your skirt, before being stumped at how your panties work. You quickly wish them off, and they disappear back to your closet.
"How'd ya do that?" Mino asks, before you pick up the tattered remains of your new bovine friend's overalls.
"Do you want this back?" you ask, fixing it with a flicker of the ring's power. You're getting pretty good at this. "If not, I'll transform it into a bunch of jeans and give it to charities." you say.
"Can Ah?" Mino asks, "Also, if it ain't too much trouble, could ya make it larger in the chest?" she grabs her swollen tits, and a little milk drops out of them. "It seemed like it got tighter as time wen' on."
"Oh, it wasn't getting tighter," you say, teleporting it to Mino's closet, "Your breasts fill with milk, getting bigger and bigger. If you were a normal human, you'd just feel painfully sore. As a minotaur, I ruled that your breasts can expand a hundred-fold, holding milk like a ballon, before that'd happen," you explain. "Zen, have you got any milking equipment for Mino, or will I have to magic some up?" you ask, sitting next to Mino.
Zen pulls out some high-quality breast milk pumps, the type for people who are a bit over productive. "Will this do? It's the strongest in here," she says.
"I'll magic some up then," you say. The room behind you expands, gaining some farm level equipment. The same is sitting in the new bedroom upstairs. "Mino, these are Milk Pumps. They'll suck out your milk. All you need to do is attach one cup to each nipple, and press start, and it'll stop when you run out."
"Oh, that's convenient," Mino says, looking backwards.
"Alright," Zen says, prompting Mino to turn back. "Let's start with..."
