Chapter 179 Going Down On Kath

Thursday started quite early for Alan. He was sleeping in bed when he awoke to the sensation of someone gently shaking him. "What? ... What?" he mumbled and opened his eyes.

It was pitch dark, and his sister was leaning over him, naked. Her shapely boobs dangled inches from his face.

"Is it morning already?" he whispered. Then he answered his own question with a glance at the clock next to his bed. It read one minute after midnight.

"It's Thursday already, Very Big Brother," whispered his sister very quietly, "and you know what that means! I'm now your complete cocksucking fuck toy, and today's the day we consummate our love!" She kissed him passionately on the lips, pulled back his covers, and began to fondle his rapidly rising prick.

She paused in her kiss and added, "I thought of waking you up with a blowjob, but I was worried you might be confused and yell out. And we wouldn't want that!" She planted another kiss on his mouth.

Alan reached out and fondled her tits while she was kissing him. There was no longer any reason to maintain any boundaries with his sister, except for the fear of getting caught. However, that was a huge consideration, so he felt panicky even though he couldn't stop himself from returning the kiss.

When they finally had to stop to catch their breath, he whispered urgently, "We can't do this! Mom and Ron are in bed just down the hall! What if they hear something and catch us? You're totally naked!"

She said, "So what? I'll be quiet. Really quiet. You don't know how much I've been waiting for this! I've practically been counting the seconds!"

He felt a bit bad, because he was eager too, but obviously not as eager as she was. In his defense, there were a lot of interesting sexual things happening to him lately and keeping him distracted.

He said, "I know, I know, I know. But really, we have to be smart. Mom AND Ron, just down the hall? Come on."

She agreed, in theory. "You're right; we can't do this. There's no way I'm going to get caught and lose out on all the fun. But just this one time, pleeeeaaase?! I'm so worked up for today's special treat! ... I'll tell you what. If I put your dick in my mouth, then that will stop me from talking..."

She bent her head down and fed his cock between her lips even as she said this, effectively silencing herself just as she'd suggested.

Although he'd been successfully resisting her overtures at home for the last few days, while Ron was there, he had next to no willpower left. The best he could do was a feeble protest: "Sis, what do you think you're doing?!"

Katherine thought that was so amusing that she burst into giggles, which was an interesting experience for him since more than half of his erection was between her lips at the time. Finally, she stopped giggling to mutter with her mouth full, "What doeth it wook wike, thilly?" That resulted in a new burst of giggles.

He groaned with pleasure, but also with frustration at his lack of willpower. "Okay, dumb question, I'll admit, but we're just gonna stop there, right? I mean, we don't want to ruin our first time due to fear of being too noisy, do we?"

She tried to nod in agreement, but since her head was already bobbing up and down on his rod, the nodding just looked like more bobbing.

Even so, he took her silence for agreement. "Good. To tell you the truth, there's something I want to try. What if you swing around and put your ass in my face so I can finger you down there? Would you like that?" He'd fingered both Suzanne's pussy and ass just the prior evening, so he was willing to try it on his sister too.

Katherine immediately disengaged and began repositioning herself. "You kidding? Having you eat me out would be a dream come true!"

He soon found her swampy slit just inches from his nose. "Well, I didn't say anything about eating. Let me take it one step at a time, okay? Just try your best to keep quiet. Real quiet."

He plunged his index finger into her hot gash and twisted her clit at the same time.

She wanted to yell so loudly that she'd wake everyone within shouting distance. But thankfully, although her mouth opened as wide as it could, she remembered her parents down the hall and all that came out was a quiet little yelp. Then she let out a long sigh. "Brother, watch out! Don't arouse me so much or I won't be able to help myself!"

Now he giggled. "Okay. I'll try to be bad at this." He tapped and stroked a spot on her hip far from her erogenous zones.

"Not there, you doofus!" she whispered even as she giggled back.

"You said be bad."

She let out a loud sigh. "Brothers!" she whispered with exaggerated exasperation. "Can't live with 'em; can't kill 'em. I guess I'll just have to blow you some more instead." Her lips clamped down around his cockhead again.

He didn't exactly follow that logic, but he wasn't about to argue with it. As she nibbled and licked her way up and down and all around his dick, he concentrated on her pungent pussy. He plunged two fingers in and out of her slit, trying to time it with the bobbing of her head whenever possible. But knowing that she wasn't the greatest when it came to keeping quiet, he went easy on her clit, brushing against it lightly from time to time but never pressing hard on it or giving it a good twist.

What he didn't realize was that she loved his feather-light brushes even more than the harsher treatment. But she was determined not to get caught, so she kept her purrs and moans at a very quiet level.

Since he was concerned about getting caught, he didn't struggle with all his might to delay his cum. Besides, he was too worked up to last long in any case. After about five minutes, he whispered, "Sis, I'm gonna lose it; it's coming fast! Watch out!"

She had time to pull away if she had wanted to, but instead she took him deeper. It was a struggle though, not to choke or gag as a larger than usual load of cum flooded her mouth. She had to pull back bit by bit and ended up taking the last two ropes on her cheeks and chin.

She sat up so she could look him in the eye through the darkness. She ostentatiously swept her cheeks clean with her index finger, drawing all the cum into her mouth. "Mmmm. Yummy midnight snack," she said near his ear. "I could make this a nightly habit."

"Don't you dare!" He whispered back with genuine concern. "Sure, it sounds great, but it's asking for trouble. What about Ron?"

"Ron, schmon. Like I care about what he thinks. Anyway, that didn't stop you or Aunt Suzy from having fun in the house last night when she sucked you for well over an hour straight."

"You know what we did?! Did Aunt Suzy tell you?"

Katherine rolled her eyes and sighed. "Duh! Men are so clueless. Of course! We found out from her after the fact. But we didn't need to be told. Since she was the only one of your cocksuckers around, we knew what was going to happen before it happened. And you know what Mom confessed to me?"

"What?"

"She was totally distracted throughout the entire movie, thinking about what you and Aunt Suzy were doing."

"Really?!"

Katherine just shook her head with mock disdain, acting like she was talking to an idiot. "Really. She squirmed through the whole movie, like she had to go to the bathroom. She was scared that Ron would notice something was wrong. Knowing her, I doubt she even knew what movie she was watching. What exactly did you and Auntie Va-Va-Voom end up doing, anyway? She just mentioned that she helped you without revealing any details."

"You pretty much nailed it on the head already. She basically sucked my dick for an hour and a half straight," he quietly admitted. He worried that his sister would get territorial and jealous over that.

But Katherine merely made an appreciative noise (even though she was jealous on the inside). She whispered, "I knew it! Damn. Some women get all the fun. Next time, I want to be the one who stays home with you. But until then, Very Big Brother, I promise to be good around the house, Ron or no Ron. And quiet, too."

She flashed a naughty grin. "Whenever I get too talkative, just stick your fat slab in my mouth to shut me up. And remember, after school... I'll be waiting for you..." She got up to go.

With a quick thought to spur him, he hopped out of bed and reached the door first. He figured it was much better to have his head poke out and scan the hallway than his sister's. He took a quick peek into the hallway, to make sure the coast was clear.

Deciding it was safe, he let his sister scamper the ten or so feet to her room across the hallway. Not too surprisingly, that night they each had very graphic dreams about what they anticipated for later that day. That resulted in two sets of messy sheets.
