"Hey, Sam, can I talk to you privately for a minute?"
Sam turned his head to look across the kitchen table at his cousin Hillary, who had just spoken. He was confused; the buxom brunette, like most of his family, usually pretended he didn't exist. She was hot, though; not only that, but she was a step-cousin, unrelated by blood to the Carson family, meaning he had a chance to score with her. The two had fooled around quite a bit in their childhood; maybe that's what this was about. "Sure thing, Hil," he said nonchalantly, "but I'm sure that the rest of my family still has a lot they want to talk to you about. This is the first time in forever you've been over, after all." As he spoke, he motioned to the rest of his family, sitting around the table just like they were.
"It's fine, Sam," Pamela (Sam's mother) interjected, smiling. "We can wait. Hillary never does anything without a reason, after all. That's why we get along so well," she continued, smiling at her adoptive niece as she spoke. "Go ahead."
Hillary nodded, getting out of her seat. "Thanks, Aunt Pam," she said gratefully before turning to look at Sam. "I'll be waiting in your room when you're ready." She walked around the table, moving towards the stairs to the bedrooms upstairs; Sam got up as she passed by, following right behind her. As the pair walked up the stairs, Sam got a great view of his cousin's amazing ass in yoga pants; he felt the beginnings of an erection begin as they finished walking up the stairs.

A minute later, the pair was in Sam's room. The place was surprisingly clean; Sam spent most of his time out, so he wasn't around to make much of a mess. Hillary pulled the rolling chair out from the desk, motioning for Sam to take a seat there. He took a seat, wondering what in the world was in store for him.
"So, Sam," Hillary said, sitting on the bed a few feet away. "here's the thing. I'm sure you remember that I have magical powers, right?"
Sam nodded. "Of course I remember. It's the reason you were adopted into the family, and Sarah won't stop talking about how she's looking forward to getting them. What about them?"
"Well," Hillary muttered sheepishly, "I'm looking to test out a new spell. Would you mind helping me?"
Sam shook his head violently in response. "Nonononono. Last time I helped out with my mom's spells, I ended up in the hospital. I'm never doing that again."
Hillary sighed. "Oh, fine. I guess I'll have to find some other way."
The pair was silent for a second before Hillary flopped onto her back, setting her massive breasts jiggling all over. "This bed is super comfortable, you know? It's really relaxing."
"Yeah, it is," Sam replied absentmindedly, too busy watching Hillary's breasts bouncing.
Hillary's eyes suddenly glinted, as if a lightbulb had gone off in her head. "You like these, huh?" She said seductively, placing her hands on her massive mammaries. Sam could only nod in response as he watched her massage her giant funbags. "This feels really goooood," Hillary moaned softly as she continued playing with them, her nipples beginning to poke through the fabric of her tight T-shirt. She looked at Sam with lust in her eyes, smiling seductively. "It's really relaxing, feeling hands caressing my big, round, heavy tits. You can almost feel how heavy they are, can't you?"
"Yes," Sam responded, lisping slightly. His eyelids were beginning to grow heavy, but he couldn't stop watching Hillary fondle herself; this was a once in a lifetime opportunity. A tent was beginning to form in his pants.
"They're sooooo big," Hillary continued, each motion of her hands sending ripples throughout the jiggling flesh. "they just take up so much of your vision. So hard to focus on anything but my big round tits, isn't it?"
"Ys," Sam muttered, finding it hard to open his mouth for some reason. His eyes were half-lidded now; every passing moment made it harder to keep his eyes open, but he had to keep watching her breasts. He just had to.
"They're heavy too," Hillary continued, watching as Sam was hypnotized by her breasts. "Heavy like your body right before you're about to fall asleep. I bet if you saw them, you'd fall right into a trance, wouldn't you? They'd just be sooo, big, and sooo heavy."
Sam only nodded this time; he couldn't open his mouth. He was so tired, but he had to see those breasts before he could fall asleep. Those big, round, perfect breasts...
"You ready?" Hillary said. "I'll show them to you on three. One...Two..." She lifted her T-shirt, revealing her F-Cup breasts in all of their glory. Sam slumped forward, asleep; Hillary's hypnotic trick had worked. She lowered her T-Shirt again, sitting back up to face her sleeping step-cousin. Hopefully, the hypnosis-induced sleep would be particularly receptive, allowing Hillary to apply the Slave Curse perfectly. She began chanting an incantation, as magic swirled about...
