Alan and Katherine came strolling into the kitchen and dining room area together, fully dressed. Alan went straight to the kitchen, and Katherine sat down at the dining room table.

"Good morning, Mom," he said to Susan as he walked up to her. He purred with approval as he blatantly looked her over from head to toe. "You look extra hot and sexy. Nice!"

Susan felt a tingling shiver of lust shoot through her, but she tried not to show it. "Good morning, and thank you," she replied warmly. She preened, striking a sexy pose. "You think?"

"I know." He kissed her on the cheek. "By the way, I like your heels."

Susan beamed. "You do? Suzanne uh, OH! Tiger! ... Suzanne bought them for me."

Her comment was cut off because Alan simply slipped both the straps off her shoulders and then grasped her newly exposed big tits with his hands. He gently squeezed her nipples, forcing a bit of milk to dribble out.

Susan was left breathless. Oh my goodness! Today is going to be a VERY good day! He’s frisky AND erect!

"That’s nice of her," he said casually while rubbing his face in her cleavage. "Please thank her for me." He inhaled deeply of her chest. "You smell nice too. Kind of like strawberries and cream."

Susan was trembling with delight, and gasped especially loud when he dropped a hand down the back of her miniskirt and firmly squeezed an ass cheek.

But just as quickly, he withdrew from her and even pulled one of her straps back over her shoulder, leaving one boob covered. He looked around the kitchen, as if interested in other things. "And speaking of tasty fruit, what are you making? What’s for breakfast?"

Susan though was still reeling from near orgasmic pleasure, and was too dazed to immediately answer his question. Good Lord! He just comes strolling in here, and manhandles me, and yanks my clothes off like he owns me. And of course, HE DOES! He OWNS me!

She nearly climaxed just from thinking that. She certainly would have if her privates had been touched at the right moment.

But Alan didn’t notice her trembling because he was looking at Katherine. "Sis! What the heck is wrong with you?" Pretending anger, he left the kitchen and went stomping over to where his sister sat in the adjacent dining room.

"What?" she asked, in a haughty and uncaring tone. She chomped down on an apple.

"First off, you come down here and you don’t even say hello to Mom, after all she does for you. Then you just sit there fully dressed, like you’re expecting Christine to show up or something."

"Well, so what if I do? Maybe I’m cold."

"Maybe you’re cold?! Just who’s the master around here?"

She looked guilty. "Um, you are."

"And who’s the sex slave?"

She bowed her head dejectedly. "Uh, me. Mom and me."

Susan was watching, completely shocked. She didn’t realize that this was a role-play her children had worked out in advance. Upset by her daughter’s sulky attitude, she stormed into the dining room as quickly as her high heels could carry her. As she reached the table, she slid her other strap down her shoulder so her other breast was freed too.

"Damn straight!" she boomed, while striking a sexy pose that emphasized her exposed and lightly bouncing globes. To her delight, her flimsy top quickly slid all the way off her body. "Tiger is in charge here, and don’t you ever forget it! Does that collar around your neck mean NOTHING to you?!"

"Of course it does. But he’s only one year older than me," Katherine pretended to gripe. She fingered her collar, feeling guilty that she had to say such things, even in a role-play. "Why should he be in charge?"

Susan was temporarily struck speechless. But she recovered, thundering, "Why?! Because he’s tamed you, and me, and the rest of us, that’s why! He’s proven his natural superiority, and you know it! Now, get your face in his lap and let’s see some stealth sucking while he eats breakfast before I get REALLY mad! Or... don’t tell me you don’t even want to suck his cock? I’m... I’m... speechless! Have you gone completely crazy?!"

Susan had been looking forward to doing the stealth sucking herself, but she figured it was more important that Katherine be reminded of her place as one of his personal cocksuckers with a prolonged cocksucking session.

Alan put a hand on Susan’s shoulder. "Mom, let me handle this." But his hand quickly slid down to her nearest bare breast and gave it a honk. "By the way, how’s the milk? Do you need to be drained?"

Susan was grimacing angrily, trying to be nice to him while still feeling irate at her daughter. "I definitely could use a good suckling, I’ve been holding out all morning, waiting for you. But don’t worry about that right now. Put some sanity back in your sister first!"

"I’m not worried," he replied calmly. "She’s just seeing how far she can push me. But Sis, you went over the line." He spoke to his sister in a much sterner tone, "Strip, and then bend over the dinner table, face down."

To Alan’s amusement, Susan started to step towards the table and pull her miniskirt down.

"Not you, Mom. Please, go back into the kitchen and let me take care of this." But while his words said "go," his hands said "stay." He lifted up his mother’s short skirt and fondled her exposed ass with both hands while watching his sister undress.

Susan was gratified to see that he was taking control of the situation. She decided to stay for as long as he wanted to enjoy her ass.

Katherine was pretending to be surly about it, but she was finding it increasingly difficult to hide her arousal. She couldn’t help but put on a sexy show as she took off her clothes. This part of the role play she liked. As she danced and stripped to "Master and Servant" by Depeche Mode on the Sex Slave Mix CD, she thought, I’ve been baaaad! Really bad! Brother, punish me GOOD!

"Yes, Son," Susan said between sultry moans. "You’re really gonna... take charge! Aren’t you? You’re gonna... show her... her place!" She was right on the edge of a big orgasm, especially because Alan continued to knead her sensitive ass cheeks.

But then he pulled her miniskirt back in place and gave her ass a slap.

Unfortunately for Susan, it wasn’t the start of a spanking; it was a gesture directing her back to the kitchen. Even so, she very nearly fell to her knees in orgasmic ecstasy after his hand smacked her. She was so worked up that it was a challenge for her to stagger back towards the kitchen.

She only made it as far as the stools in front of the kitchen counter, and then she had to sit down and try to recover. Oh my Lord! Is there anything hotter than seeing him take control of his rebellious sister while treating me just like a sex pet? I think not! He put both of us in our place at the same time!

Katherine, meanwhile, had completely stripped faster than she wanted to, as she wasn’t wearing underwear. She bent over the table at a right angle and excitedly wiggled her ass around before she remembered that she wasn’t supposed to be happy. "I’m so sorry, Brother!" she pretended to apologize. "You’re right that I didn’t really mean it; I was just testing you."

"Well, it’s too late for apologies now. You still need to be punished."

"Oh, no! What are you going to do to me?!" Again, she couldn’t help but wiggle her ass around. Even though this was a pre-arranged act, she was getting carried away. She felt like she really was getting punished, and she loved it.

Alan, too, was starting to forget that this was supposed to just be an act designed for Susan, and he was getting into it as well. His dick had been firm and erect pretty much since he’d strolled into the kitchen, and now he whipped it out of his shorts and laid it along Katherine’s ass crack.

Susan gasped, loudly. YES! That’s it, Son! It’s time for some sister-taming!

Forgetting her role, Katherine cooed lustily. "Big Jai Alai Stick Brother, what have you got for me there? Hmmm?" She bucked backwards, as if trying to catch his dick with her pussy.

He snorted with laughter at her obscure phallic object reference. But then he said, "Hey Mom, can you get me some kind of lubrication? Something from the kitchen will do, like olive oil or even a stick of butter."

Katherine’s asshole was already lubed up, but she didn’t say anything, since she figured it would be better (and sexier) if he lubricated himself and her too.

Susan stumbled to the refrigerator on wobbly legs and got a tray of butter. Seeing it there in her hand, and thinking what Alan might use it for, she nearly collapsed on the floor. Somehow, she managed to stagger back over to where Alan was rubbing his dick all over his sister’s ass. Her miniskirt was askew, but she was too frazzled to notice.

Her mind filled with vivid images of Katherine having her ass violated right there on the dining room table while she watched from a short distance away. She whispered in awe, "What are you going to do? Not in her ass?"

"Yes, the ass," he said firmly.

Katherine was just alert enough to remember to shriek with distress.

Susan gasped. "But she hates that!"

"I know." Actually, Katherine didn’t really hate it, and Alan knew that Susan was aware of that, since Susan and Katherine kept no sexual secrets from each other anymore. But he also knew that Susan was aroused by anything suggesting he would have his way with her against her will. Since this fit into that, he played along.

Sure enough, Susan’s nostrils flared and her eyes went wide with excitement. Her heart was practically thumping out of her chest.

He casually added, "And I hate it when she tests my authority." He swatted Katherine’s left ass cheek hard to punctuate that.

Katherine shrieked again, and this time she didn’t have to fake it.

Susan clung to Alan’s left shoulder like an adoring groupie. "Son! You’re so... forceful! So manly!"

Knowing that Susan was as aroused as could be, he stuck his hand out towards her and ran it all over her tummy. As his fingers went up and explored the sensitive undersides of her huge boobs, he stated matter-of-factly, "Mom, when I say that you and Sis are my sex slaves, I really mean it. I expect total obedience and submission. Do you understand?"

His hand drifted down her tummy again and kept going down. He pulled down her miniskirt as his fingers reached her bush.

This was simply too much for Susan to take. She looked at his hand, her miniskirt slowly sliding down on its own to her knees, the tray of butter on the table, and his dick resting in between the upturned cheeks of Katherine’s ass, and she started to whine. The whine quickly turned into a high-pitched wail as an orgasmic wave of lust and desire washed over her. There were a few "YES!"-type sounds in there, as she valiantly tried to answer his question.

She literally was unable to stand, and crumpled to the floor.

For a few seconds, he was concerned that she’d hurt herself, but she obviously was just fine, since she kept squealing with delight. She even pulled herself together enough to diddle her clit, which set off yet another round of ecstatic squeals.

He was chagrined, but in a pleasantly amused way, because the plan had been for him to fuck Katherine’s ass in order to push Susan over the edge, yet his mother was already over the edge and he hadn’t even started. However, he resolved to keep going anyway. Katherine’s ass looked too tempting to resist, and he wondered if he might get a better result than last time, now that he was more talented with anal sex.
