The Omnistore System

Chapter 134 Cooking with sister (R-18)

"I really need to quit these antics," Maria mumbled as she removed the butt plug from her rear end. "Ahh, that's a bit of relief," she sighed while examining the now somewhat slimy plug.

Setting it aside, she casually stretched her anus with one hand, revealing the aftermath – a detailed, gaping anus. Oddly enough, even though it was chilly in the park, her pubes around the anus seemed slightly moist from perspiration.

"It's gotten so loose," she grumbled to herself as she used her second finger to check things out. It used to be a whole different story, but now it's like a smooth ride in there.? Before, she would moan when anything was inserted by finger, but now it was sliding in easily. She could feel the bumpy texture inside her anus with her finger.

"Guess it's time to clean it...hope he is gonna use it .... but with Riya here, how are we he gonna do it?" she mused while turning on the shower. The whole idea of Kevin's upcoming date had vanished from her thoughts, or she just did it intentionally. But one thing was clear, right now, all she could think about was satisfying her desire; the day's teasing and play had left her eager for some relief.

She could have chosen to masturbate if she wished, but Kevin had forbidden her from doing so. Even though she was his mother and could technically disobey his orders, she found a strange pleasure in obeying him. The mixture of guilt, shame, and a feeling of moral ambiguity that followed obeying her son's lewd orders was somehow more appealing than a simple orgasm. Besides, she was certain that Kevin would eventually grant her the release she craved after all the teasing.

It was the teasing that she despised the most. Maria found it difficult to endure, as it easily grated on her nerves. However, Kevin seemed to enjoy it, so she tolerated it as much as she could. Today had been particularly humiliating, especially when she had to push the butt plug out in the park – "it felt like having a shit right in front of him." She muttered with embarrassed face and got more when remembered she did it in park, it was fortunate nobody see her doing it expect Kevin.

"fuck, it was so messed up..." she muttered to herself, a rare departure from her usual composed demeanor. Maria considered herself quite modest, even wearing a veil when she ventured outside the house to ensure that no men, apart from Kevin, could catch a glimpse of her. Initially, she had done it for his father, but now it was for Kevin, and it brought her a strange sense of satisfaction by doing it.

With various thoughts swirling in her mind about how Kevin was going to have sex with her tonight while Riya was present in the house, she contemplated her options while showering. The warm water helped wash away her fatigue, while her son and daughter were upstairs preparing dinner.

Riya's eyes welled up with tears as she continued to wipe them away, frustrated by the irritating onions. She muttered in annoyance, "Kevin, can you take over this onion duty? My eyes are on strike." She looked at Kevin with hope in her eyes as he was busy washing what appeared to be some kind of bird meat, complete with two drumsticks and other parts. With a nonchalant tone, he replied, "yes I can, But if you want to savor the delicious ember chicken, you'll have to do it yourself or just leave it." He showed her a slightly reddened and shiny drumstick as an enticement.

Riya's mouth started watering just thinking about that ember chicken. She wiped her drool away and shot a frustrated look at her brother. "It's not fair, you're taking all the easy tasks and dumping the tough ones on me. Come on, I can handle washing the chicken. You should be chopping those onions," she argued. With a thud, she dropped her knife onto the chopping board, reaching for the chicken.

However, Kevin quickly pulled it out of her reach, saying, "Well, you should've also taken care of the other veggies, peeled and washed the shrimp, and done the dishes. I only asked you to handle the onions, and now you're even bitching about it? Seriously, sis, you're letting me down." He shook his head, clearly unimpressed.

Riya was getting a bit irritated by Kevin's words. With an annoyed snort, she returned to chopping the onions, muttering, "Who does he think he is, bossing me around? I should be the one giving orders to him as an older sister. Such a brat, he is!" She muttered this loudly enough for Kevin to hear.

Kevin, still grinning at Riya's amusing outburst, changed the subject. "Hey, I've got something for you," he said casually, pulling out two sets of clothes. One's red, and the other's purple. They're made of silk, by the way. Purple's got some silver button, and the red one's rocking dark silver ones.

Riya snatched the purple dress from Kevin and quipped, "Nightdress, huh? Looks fancy. This one's for me, right?"

Kevin nodded with a smile. "Yep, it's all yours, and it even comes with shorts." He watched as Riya examined her new clothes.

Riya raised an eyebrow and questioned, "Why shorts instead of pajama pants? These look tiny; they'll barely cover half of my thighs." Noting that the shorts seemed a bit too short to provide adequate coverage for her muscular thighs.

Kevin shrugged, coming up with a quick excuse. "Mom said shorts would be more comfortable," he fibbed, not wanting to admit that he had bought them without checking the size properly.

Riya muttered to herself, "Why did she ask for shorts? It's getting cold; she should have asked for something warmer."

Kevin shrugged again, trying to maintain his story. "I guess she thought they looked nice. You know how moms can be sometimes. They have their own fashion sense," he said with a grin.

Riya nodded while Kevin walking toward the stairs said,? "I'm going to give mom hers, and I also have to go to the store to buy something. Just cut the onions and put the chicken to boil, and do the same with the onions after cutting them, okay?" Kevin asked before heading downstairs, not waiting for her answer.

As she examined her new nightclothes, she muttered, "He has become an adult." A nostalgic and somewhat sad expression crossed her face briefly. However, she shook her head to clear those thoughts and decided, "Let's cut these onions first, or he's going to give me an earful."

Lost in her thoughts, she didn't notice that Kevin had gone outside without wearing his shirt.
