Melona frowned. "Mom, please, if you're trying to joke, I'm not in the mood."
Melina's smile stayed in place. "No, look!" She drained what was left of her tea. "Indu credus." Melona wasn't sure what spell that was, but the more her mother talked, the more she was inclined to believe her. Melina wasn't the joking sort. She didn't have the brainpower. "And now--"
Melona watched as her mother's breasts swelled, cringing a little at the obscene moan that accompanied the spectacle. "Mom!"
"Sorry honey," gasped Melina. "I haven't tried to do this in years, and--oh gods it feels really good." She rubbed her thighs together, grabbing at her bust. To Melona's horror, Melina grabbed her top and pulled it over her colossal tits, exposing a pair of rock-hard nipples.
"What the fuck?" asked Melona, horrified not only at this display, but at the large white droplets leaking out of Melina. Melina reached up, grabbed her nipples with a not-inconsiderable amount of effort, and aimed them towards her empty teacup.
"Language, dear," said Melina in between moans. She began to squeeze and pull at her leaking nipples, letting her milk spray into the cup. "Just because I'm showing you how our power works doesn't mean you get to--get to--fuuuuuuck!"
Milk began to flow freely from Melina's nipples, spraying as though from a fountain. Her legs buckled, sending her ass back into her chair. A few stray gouts of milk caught Melona in the mouth. She hated to admit it, but A: it didn't taste bad, and B: at this point, she'd believe anything her mom told her. She stared at Melina for a bit.
Melina grabbed the edge of the table, pushing herself up on trembling arms. "Sorry, darling, I know I'm a hypocrite, it's just--" she shuddered. "The bigger you are the better it feels."
Melona tried to catch her train of thought as Melina tucked her tits back into her dress. "You said the milk was magic. What can it do?"
"Oh, anything!" Melina started smiling again when she saw the shock on Melona's face. Melona, for her part, would have never believed this, but based on what had just happened, incredulity seemed like a bad idea. "Well, not anything anything. It's still just milk until somebody drinks it." She screwed up her eyes, trying to think of a good comparison. "It's like a potion, except you don't have to get ingredients for it, and you can't really screw it up, and it can be way stronger if you want it to be! Oh, but if you don't pick what effect it has, it'll just have the same power as the spell you last cast."
"So, what was in that milk?"
"Oh, I don't remember the name," said Melina. "But it makes people believe you. I thought it'd help me explain things a bit better."
Melona felt violated all of a sudden, but she had to admit it was a shockingly smart move on her mom's part. "I see."
"Anyway, that's why your father wanted to marry me so badly! We had an amazing business together for a while." Melina's smile turned devilish. "Well, he also wanted to marry me because of the hypnosis spell I put in the milk for his morning coffee."
Melona stared at her mother in silent horror, then stood up. "I--um. I think I should go."
"Okay, honey!" said Melina. "I know it's a lot to think about. Just come back whenever you want, okay?"
"Yeah, sure." With that, Melona turned around and headed back to campus.

A while later, and Melona sat on the edge of her bed. Her mom's words still rang in her head. Had she brainwashed Dad? Was she as dumb as she acted? Was she actually telling the truth, or was this just a sick prank on her part?
"Indu credus," she whispered pointing at the wall. The belief-inducing spell glanced harmlessly off the stone. As Melona waited, she could feel a warmth in her chest, one that seemingly traveled all the way down to her crotch. What was more, she could feel that warmth running down the front of her chest, dampening her robes.
Melona didn't know whether to scream in delight, fear, or both. Either way, she decided, she was going...
