Susan cooked a late dinner for four that night. She made one of Ron's favorite meals, Vietnamese phở (pronounced "fuh") beef-noodle soup and fish cakes, hoping he would wake and come downstairs. Instead he continued sleeping, so Susan told her children she wanted to sit with Ron while he slept. That gave Katherine and Alan the excuse they needed to get out of the house to implement their movie plans.
The late dinner caused them to miss the nine o'clock movie showings, so they went to an eleven o'clock movie instead. As a result, the theater wasn't that crowded, even though it was a Saturday night. Katherine insisted on sitting in the back row, which left them all alone.
Now that they were alone, away from any prying parents, Katherine wanted to make something happen with her brother, though she wasn't sure exactly what or how. Additionally, she was very mindful of the fact that Alan had gone out on a date of sorts with Christine the night before and she'd learned that he'd given her a good night kiss. As a result, she was determined to blow his mind and make him completely forget that he'd ever even heard the name 'Christine'.
She cleverly had them go to a far-off movie theater, so the odds were very low that anyone they knew would be there. She wore a sweater and skirt when she left the house, for the sake of her mother's eyes, but as soon as they left she took them both off while Alan drove the car. That left a low-cut blouse that buttoned down the middle of her chest and a black miniskirt, and nothing underneath them.
Katherine had insisted they watch the Hugh Grant romantic comedy "About a Boy," which was rather odd because she had no interest in actually watching the film.
From the minute the movie started, she began to unbutton her blouse. "Alan, isn't it hot in here?" she said as she undid the few buttons which held her blouse closed. "I'm burning up."
"No it's not," he replied in a frustrated tone. "They have air conditioning!"
"Oh, do they?" she responded innocently. "Maybe that explains why my nipples are getting all hard."
By this point she was unbuttoned all the way, so she opened her blouse completely to show Alan what she meant by her nipple comment. She spoke casually, "So how was your movie date with Christine last night? Did she show you her tits? I'll bet not. Mine may not be as big or as nice, but you can play with these any time you like."
"Katherine!" said Alan in an urgent whisper. "I thought you said you weren't going to tease!"
"I lied. Anyway, I think the air conditioning isn't working or something, 'cos I do feel really hot. Maybe it's because I'm sitting next to you."
"Katherine! We're in a public place! Have you no shame? What if someone who knew us from school saw us here?"
"No shame. Anyway, I took a good look at the crowd as they were coming in. I didn't recognize anyone, so we're safe. After all, we're miles from home. Plus, your body is blocking the view from the aisle. And finally, that's what the popcorn is for." She motioned to the two large cups of popcorn they both had in their laps.
Alan looked puzzled, so she asked, "Don't you know the old popcorn trick? I saw it in a movie."
"Before you explain the popcorn trick," interrupted Alan, "are you thinking about what you're doing here? We're in a public place, and I don't think-"
"I know what you've been doing with Aunt Suzy and Mom!" she whispered very quietly, cutting him off. "I even listened outside your door while Mom gave you a blowjob. And I spied on you giving her a 'massage' the other day - you did it right in the living room where anyone could see! The stuff you've done with Mom. Come on, really! It's funny you should be the one to talk about caution! My attitude is just like theirs. A little fun, even sucking a little cock, is perfectly okay and very therapeutic for you. I'll bet you haven't cum six times yet today."
From the look on his face, she knew she was right on that point. She continued, "As long as we don't actually have sex, then what's the harm? You remember what Clinton said - a blowjob isn't sex. Do you doubt the former President of the United States? I'm sure he wants me to give you a blowjob right now, in fact. He's all about family values," she giggled.
She began to unbutton and then unzip his pants with her one free hand, while her other held the popcorn.
"Katherine!" Alan hissed quietly, and made a halfhearted move to stop her hand. "I can't fucking believe this! In a movie theater, no less!"
She asked petulantly, "What's with all this resistance? Is it that you don't like me? You don't find me attractive? Is it that I can't compare to our 'Ms. Tits of the Universe' mother and her equally-stacked best friend, not to mention your girlfriend Christine?"
"She's not my girlfriend," he hissed.
"Whatever. I see the way you ogle her big 38Gs. Why is it that almost all the females you really like seem to have enormous breasts? What are the odds of that?! Well, I can tell you, breasts aren't everything! How can I possibly compare with S and S? They're both inhumanly gorgeous." She was trying not to use names in case anyone overheard.
"You're pretty gorgeous yourself," he whispered urgently. "And don't mention that kind of stuff in public, like talking about our you-know-what. You're a complete stunner. I'm so lucky to have you as my, well, as my you-know-what. You'll be every bit as much a knockout as them in a few years. But you're younger than me-"
"Hey! We're almost exactly the same age." She kept pulling down his pants zipper and Alan kept zipping it back up.
"Okay, whatever. But it would be like corrupting a minor, especially since ..." He got all red and stopped talking.
"Since what?" she said, as she tugged on his zipper. She moved the popcorn from her lap to the floor, which now gave her a two-hand to one-hand advantage over her brother.
He stammered, "Like with Mom, she has limits, especially now. Even Aunt Suzy has limits. But if you and I started... You know... I don't know if there would be any limits. Between two horny teenagers, you know. I don't know if I could... How good my self-control would be. Or yours, for that matter."
"Oh, is that the problem? I'm very good at limits. Let me prove it to you. I'll give you a blowjob now and it'll stop there. I'll show you I know when to stop. That would just let me catch up to the other two."
Alan's resistance to her hands finally ended.
After getting his zipper down, she pulled out his erect dick.
"I've been waiting soooo long to do this," she whispered with glee, and began to lick it.
"So long?" said Alan, suddenly surprised. "More than the three weeks since I've been diagnosed?"
She paused briefly before mouthing his erection and said, "I'm not telling. Three weeks can be a very long time."
Then she went to town on his cock. She was tentative at first, just keeping part of the head inside her lips while running her tongue in circles around it. But she slowly took more and more in until the entire mushroomy head was engulfed. She couldn't believe just how big it was or how tough it was to stuff all of it inside her mouth.
Alan was so high from the erotic joy and the exciting fear of discovery that he thought he would pass out at any moment. The fear gnawed at him, though, and he complained, "As good as that feels, you have to stop! Can't we go somewhere and finish this in private? What if someone catches us?"
It took her a while to answer because she was having too much fun bobbing up and down on his hard shaft to stop. She thought, This is soooo nasty! I can't believe I'm sucking off my own brother, and in a public place no less! I've been aroused before, but nothing like this! I hear that some women don't like cocksucking, but I can't imagine why. I feel so in control, like he's putty in my hands. Or should I say in my mouth? Hee-hee! The way he's squirming and trying not to moan is just too cute! And if I do this just right, he's going to explode completely. I can bring him to the heights of utmost pleasure and that makes me feel so good. But not only that, I'm so hot myself that I think I'm about to drown in a puddle of my own cum! I've never leaked so much in my life!
She licked and sucked a bit more, then thought to herself, God, it IS so fucking wide and fat! It seems big enough when you're holding it, but having it in your mouth is another thing altogether. My brother is hung like a horse! And all these thick inches of yummy cock sleep right across the hall from me. I'm gonna be seeing a lot of this baby from now on, hee-hee!
Completely forgetting his questions, she started licking the most sensitive spot just under his cockhead and asked, "Tho. How wath it with Chrithtine? Did she thuck you off? In the middle of 'My Big Fat Greek Wedding' did she take your big fat dick out and give it a big fat thuck?"
"Dear God, please don't mention her," he groaned. He was already painfully aroused by what his sister was doing and how good she was making him feel by doing it. He didn't think it was possible that a person could get any more aroused than he already was. But when she mentioned Christine he overlaid his thoughts of his sister blowing him with thoughts of the sexually repressed Christine doing the same. He imagined how good it would have felt if, in the middle of the movie the night before, it was Christine who suddenly bared her big breasts and then started sucking him off.
Katherine's jaw and tongue were getting tired and needed a break, so she pulled back a few inches from the tip of his dick and jacked him off instead. Looking up into his eyes, she whispered, "What's wrong? The Ice Queen doesn't put out? Boy, that's a big surprise. Would you rather get a little good night peck on the cheek or get stroked and blown all night long? Hmmm?" Her mouth was still so close to his rod that every few words she'd stop and lightly blow on his supersensitive erection.
Alan was in such a wonderful heaven that he wanted to scream for joy at the top of his lungs. But then he'd remember he couldn't do that because he was in the middle of a theater, a public place, and that would get him even more turned on and make him want to cry out even more. In the end, he tried to respond to her but could only let out a low whimpering moan.
She giggled to hear him lost in the throes of lust. Encouraged, she went back to slurping on his meaty rod. She had realized immediately that cocksucking was something she liked to do, and she suspected she would grow to love it even more. She kept imagining sneaking into his room at all hours of the day or night and holding it in her mouth for hours on end.
The only problems were that her unpracticed jaw could only handle doing it a few minutes at a time and she had very little idea of the proper technique for what she was doing, since she'd never done more than kiss any guy. But whatever she lacked in terms of technique she made up for in sheer enthusiasm. However, she did start to gag at times from being too ambitious.
Her lack of endurance and skill actually worked to make both of them even more crazed with lust. It seemed that just when he was ready to blow, she'd pull off to rest. Then, trying to make up for the fact that she was only jacking him off, she would say the most delightfully naughty things. This process would repeat every few minutes.
Even then, his arousal was so high that he would have cum long before, except that she didn't know where all his sensitive spots were. So she was able to keep going for nearly half an hour purely by accident.
Not only was he completely unaware of what was happening on the screen, he hardly would have noticed if the lights had been turned on and someone had slapped him in the face. He was so in love with life at that moment that tears of joy actually leaked down his face.
Katherine was jacking him off and whispering, "So, would 'my big fat Greek tits' treat you like this at the movies? I think not. I'll bet Christine made you pay for both tickets and all you got was one lousy kiss on the cheek for your trouble. Am I right?"
Alan didn't reply, but she was right.
She continued, "I'll tell you what. Next time we go out to a movie you only need to buy one ticket, because I'm gonna sit on your lap the whole time! Except that I'm not going to wear any kind of skirt at all and you're not going to wear shorts or jeans. I'm gonna sit down on your huge log! That'll keep me in my place in more ways than one! We should watch a really exciting flick so I'll bounce up and down a lot. Would you like that? Would you like to spend a few hours with your sister bouncing in your lap? Why, it would be almost like fucking!"
Even though she was only lightly stroking him at the time, her words made him finally lose control. He knew he'd lost it for sure when she whispered the word "sister" almost inaudibly, directly in his ear.
Seeing his eyes get really big, she knew he was about to blow. She immediately ducked down into his lap and began sucking and licking for all she was worth.
Alan had the most difficult time of his life, cumming in public without screaming. He had to clench his teeth together so hard that it hurt, but he managed to not make too much noise. Luckily, there happened to be a song playing loudly in the movie. At the same time, his body writhed and shook in his chair like he was in a rocket ship being blasted into space.
pαпdα Йᴏνê|,сòМ Katherine had heard that most women didn't like the taste of cum, and that swallowing it was rare. But she was determined to swallow it all no matter how bad it tasted, because it was her brother's cum and she loved him.
She boldly attempted to drink it all from the very first rope that hit the back of her throat, but it was way more than she'd expected. Mostly out of surprise, she found herself pulling back, so she ended up with most of it on her face. Alan not only ejaculated tasty cum, he also generally ejaculated a great deal of it. Still, she thought that at most it could only be a few teaspoons of ejaculate and she couldn't square that with the sensation that a torrent of cum had just blasted into her face and mouth.
A lot of it ended up on her tongue. So as his eruption subsided she found herself testing the taste and even savoring it. She thought, Hot damn! Why does everyone say swallowing is such a repugnant act? This stuff is GOOD! I would have swallowed even if it tasted like whale oil just 'cos it's my brother's, but damn! Now I DON'T want to simply swallow, 'cos if it all goes straight down I'm gonna miss out on the yummy feast.
She immediately decided that she wanted to drink as much of his cum as he could produce, on a very regular basis. She suddenly had visions of sucking him off thousands of times in the years to come. She was delighted beyond belief.
