Jack nervously approached his sister Jill's side of the bedroom, a blush creeping up his cheeks. "Jill," he began, rubbing the back of his neck. "I need your help with something."
Jill, who was in the middle of reading a book, looked up at her brother with a raised eyebrow. "Oh? And what might that be?" she asked, a smirk playing on her lips.
Jack hesitated for a moment before blurting out, "I want you to stroke my ass."
Jill burst out laughing, nearly dropping her book. "Are you sure you're not just trying to get me to do your laundry, you lazy ass?" she asked, still chuckling.
Jack rolled his eyes, but couldn't help but smile at his sister's wit. "No, I'm serious. I've been thinking about it all day and I can't get it out of my head."
Jill, still amused, decided to play along. "Alright, fine. Bend over and let me see what I'm working with."
Jack did as he was told, bending over to reveal his firm, round buttocks. Jill couldn't help but chuckle and say, "Well, at least your ass is better looking than your face."
Jack shot his sister a playful glare, but couldn't deny the truth in her words.
Feeling a little more adventurous, Jill decided to take things to the next level. She reached over to her bedside drawer and pulled out a dildo, a generous 8 inches in length and 2 inches in girth.
Jack's eyes widened in surprise as Jill held it up, a mischievous glint in her eyes.
"Get into a doggy style position," Jill ordered, a smirk on her lips. "You're lucky I'm doing this. I could be out there, finding a real man who knows how to satisfy a woman."
Jack did as he was told, his heart pounding in his chest as Jill approached him with the dildo in hand.
Jill teased him, running the tip of the dildo along his crack. "You know, you're lucky I'm doing this," she repeated, her voice dripping with sarcasm.
Jack couldn't help but laugh at the absurdity of the situation.
Jill, with the dildo in hand, started to penetrate Jack's ass. She made sure to hit his hanging balls hard, causing him to yelp in surprise.
Jill couldn't help but laugh, "You're such a baby, Jack."
But Jack, enjoying the sensation, begged for more. Jill, always in control, decided to give him what he wanted.
She reached for an even larger dildo, this one a whopping 12 inches in length and 3 inches in girth.
Jack was hesitant at first, but Jill reassured him, "Don't worry, I'll go slow. And if it hurts too much, just say the word."
Jill slowly started to insert the massive dildo into Jack's ass. He winced in pain, but Jill continued to push forward.
"Come on, Jack. You can take it. You're my little ass-istant, after all," Jill said, a teasing lilt to her voice.
Jack, now fully relaxed, started to enjoy the sensation. He begged for Jill to go faster, to which she replied, "You're such a greedy ass."
Jill, now in a rhythm, started to fuck Jack harder and faster. She couldn't help but laugh at the absurdity of the situation.
Jack, now fully immersed in the pleasure, started to moan and groan. Jill, always the tease, said, "You sound like a dying cat, Jack."
Jill, feeling satisfied with her work, decided to finish Jack off. She pulled out the dildo and started to stroke Jack's cock. He quickly reached his climax, moaning in pleasure.
Jill, feeling proud of herself, said, "Well, that was fun. But next time, you're doing my laundry."
Jack, still recovering from the intense pleasure, can't help but agree. He says, "Anything for you, sis."
Jill, with a smirk on her face, says, "Good boy. Now go clean yourself up."
