When Bigger Isn't Better: A Tale of Taboo Tush Tickling

The shared living room of their apartment was cozy, filled with the soft glow of the TV and the faint sound of laughter from a sitcom. Jack was lounging on the couch, his body twisted in a way that suggested he was trying to find a comfortable position.

Jill entered the room, her eyes immediately drawn to her brother's discomfort. "What's wrong, lazy ass?" she asked, a playful smile on her face.

Jack groaned, "My ass is sore from sitting for too long."

Jill couldn't help but laugh at his predicament. "Well, maybe you should get up and move around more often."

Jack shot her a glare. "Easy for you to say, you're not the one with a sore ass."

Jill felt a twinge of sympathy. She walked over to the couch and sat down next to him. "Okay, okay. Let me help you out."

Without waiting for his response, Jill began to gently stroke his ass. Jack's body tensed at first, but soon he let out a low moan.

Jill couldn't help but laugh at his reaction. "See, I told you I could help."

Jack opened one eye to look at her. "You're enjoying this a little too much."

Jill shrugged. "I'm just trying to help."

Jack took a deep breath. "Is there anything you can insert to help relieve the pain?"

Jill raised an eyebrow. "Insert? Like what?"

Jack blushed. "I don't know, something small and lubricated."

Jill was surprised by his request, but she didn't want to embarrass him. She got up and walked to her bedroom, returning a few moments later with a small, lubricated plug.

Jack's eyes widened when he saw it. "You're going to insert that?"

Jill nodded. "It's small and should help relieve the pain. Just relax."

Jack took a deep breath and closed his eyes as Jill slowly inserted the plug into his ass. He let out a sigh of relief as the pressure eased.

Jill couldn't resist making a joke. "Well, I guess that makes me the ass doctor now. And I'm better than any guy at this."

Jack laughed. "I'll give you that."

Jill continued to stroke and massage his ass, making sure to take it slow and check in with Jack to make sure he was comfortable.

As he became more and more relaxed, Jill couldn't help but make a few more playful insults. "You're such a needy ass," she said, making Jack laugh. "I'm surprised you can even feel anything with that plug in there."

Jack took it all in stride, enjoying the attention. "You're right, I am a needy ass. And you're the best at taking care of it."

Jill smiled, feeling a sense of satisfaction. "I'm glad I could help. Is that enough for now?"

Jack shook his head. "No, I want more."

Jill was surprised but agreed to continue, making sure to take it slow and check in with Jack to make sure he was comfortable.

As she continued to stroke and massage his ass, Jack became more and more relaxed, letting out low moans of pleasure.

Jill couldn't help but feel a sense of power, knowing that she was the one making him feel this way.

But she also couldn't help but feel a twinge of something else, something she couldn't quite put her finger on.

Whatever it was, she knew she wanted more of it.

And so did Jack.
