Eventually

"Notice that I'm here, Kiana," Zach said.

She screamed and jumped, her bare tits jiggling.

"God! Don't sneak up on me like that, Zach!" she said.

"You called me!" he said, holding his hands up defensively.

"I just...I just made you a sandwich," she said. "So here."

"Well, thanks, Kiana!" he said. "Get me a beer to go with it."

"You know, you could ask politely instead of ordering me about," she said as she retrieved a beer from the fridge and gave it to him.

"I don't think that would work," he said, then took a bite of his sandwich. "Mmm! This is really good! Why did you decide to make it for me? Are you leaning into your step-mother role?"

"I...I don't know. I guess. Can't I just do something nice?" she said.

"I guess so," he said. "Though I'm not sure why you'd choose to do it naked."

"What do you mean?" she asked, looking at him perplexed.

"Notice what you're wearing, Kiana," he ordered.

She did. She screamed much louder this time, covered her tits with an arm, her bush with her hand, and looked about frantically for her clothes. Not finding them, she turned and started to run out of the kitchen.

"Stop, Kiana," he said, bringing her to an immediate halt. "Come back and show me your tits."

Trembling, she returned, dropping her arm to stop impeding his view.

"Why am I doing what you tell me?" she demanded. "What the hell, you sick fuck!"

"You're the one showing your tits to your step-son," he pointed out. "Maybe you're the sick fuck?"

He took a swallow of his beer and another bite of his sandwich, smirking at her the whole time.

"How are you doing this to me?!" she demanded.

"Would you believe magic?" he asked. "Actually, you'll believe anything I tell you to believe, won't you?"

"No I will not!" she denied.

"Believe that you're madly in love with me and only married my dad to get closer to me," he said.

Kiana gasped.

"You...you knew about that?" she said, eyes wide. "Oh Zach! How long have you known? I've wanted to tell you for so long!"

"Stop believing what I just told you to believe," he said.

Kiana blanched, then fumed.

"Don't ever do that again!" she demanded.

He swallowed another bite and said "As long as the mayo is out, go ahead and lube up your asshole with it."

His step-mother grabbed the mayo and took a big glob in her hand, her face utterly horrified.

"You wouldn't!" she declared as she crammed the condiment in her ass

"You would," he observed. "Be generous with it, Kiana. Get your brown eye nice and supple. Relax your sphincter and enyoy the sensation of your fingers penetrating."

She blushed furiously as she obeyed and her eyes shot daggers at him but her nipples lept to attention.

"Turn around and show me," he said. "Let me take pictures."

She did and he did.

"OK," he said after enjoying the sight of her fingering her asshole for a bit. "Grab a cucumber from the fridge and work it into your asshole."

"I hate you!" she said as she obeyed. "I hate you so much!"

"Yes, I noticed," he said, sipping his beer. "But let's not pretend that it's a new occurrence."

"It's cold" she complained as she worked the vegetable inside of her.

"I'm sure it will warm up once you get it inside there," he assured her. "Or would you rather I give you something warmer to put in there?"

"NO!" she exclaimed in horror. "No, this is fine."

"I love how reasonable you're becoming, Kiana," he said. "Don't worry. I'm not going to fuck your ass just yet."

She sighed and visibly relaxed. Zach was perplexed, then realized he had ordered her not to worry. He'd need to watch his language.

"I am, however, going to fuck those big titties of yours," he said. "Lay down on the floor, tits up,"

She complied, resolved and disgusted but not worried. He pulled down his pants and pulled out his dick, which was not at all happy that he'd waited this long She looked away.

"Now, now, step-mommy-dearest," he said. "Pretend you want me to titty fuck you. Believe that if you get me off, you'll be able to convince me to lift the curse."

Kiana bit her lower lip and he could see her calculating thoughts.

"Okay, Zach," she said in a throaty voice. "I've teased you long enough. Get that big hunk of meat between my juggs!"

"Are you sure, Kiana?" he asked. "We don't have to if you don't want to."

"Oh, I want to!" she lied. "I mean, look at that gorgeous cock of yours? I want to feel it slide between my titties! I want to feel it pulse as you pump your jizm out between them!"

"As you wish, step-mommy-dearest," he said, and mounted her, slapping his meat between her pleasure pillows as she pretended to be delighted and embraced him with her boobs.

He began thrusting and she made all the noises Zach had heard her making with his father through the shared bedroom wall. He wondered if she faked them with him too.

Not that he cared that much. Right then, his main interest was in how very nice it felt to have his cock right there. He didn't know how to lift the curse, but if he did, this was no way to convince him. Not when that would mean not doing this again in the future.

He groaned and came all over his step-mother.
