Put It Where Your Mouth Is

"What? No way, this is my room, why should I leave?"

"Come on, you know that the bathroom lock is broken, I won't be safe in there! Just give your big sister a bit of privacy!"

"I tell you what, I'll close my eyes until you're done!"

"Oh no, I know you better than that! You're going to sneak a peek for sure! You'll have to turn around and face the wall. Just play with your tablet or something until I say you can turn around again, OK?"

"Yes ma'am!"

"Shut up, if you had just gotten of your ass for a minute we wouldn't have to do it this way."

Sammy turned around and switched his tablet on.

"No peeking! Don't let me catch you turning around to spy on me you perv, just keep your eyes on whatever it is you're doing on your tablet!"

"Alright already, I promise!"

He tried to focus on his game, but couldn't. On any other day he probably would have jerked off at least once or twice by now, and his dick and balls knew it. The idea that his big titted sister was undressing behind him didn't help, nor did the alcohol. It took all of his self control not to quickly turn his head around and spy on her, or maybe even switch on the tablet's front facing camera and point it at her over his shoulder. But she would definitely notice and would never let him hear the end of it. Or even worse, she would tell Natasha which meant everybody else wouldn't hear the end of it, including his parents and people at school. Besides, he could never break a promise to his big sister.

All of a sudden he remembered: the solution was right in front of him! A few months ago he had used his savings to buy a new gadget: a wireless HD security camera. Besides simply being interested in the tech, he had got it because he suspected the little brat Natasha of sneaking into his room and mess around on his computer while he was out. He had set it up on top of the closet behind the TV, so that its wide lens would cover the whole room. The device came with a companion app on his phone and tablet that allowed you to control it remotely. While it was recording it would wirelessly upload the footage to his computer's hard drive. But more importantly, the app also allowed you to see the live camera feed while it was recording!

At the time he had used it for two weeks or so, turning it on whenever he left the house and going through the recorded footage later. Once the novelty of the thing wore off it had gotten old real quick though: Natasha never showed up on the footage, and looking at hours and hours of his uneventful room that he was already in each day just wasn't very interesting. He had stopped using it, and after a while had forgotten it was even there. If he was able to connect to it now though he could spy on her without her noticing and without him breaking his promise. After all, he only promised to keep looking at his tablet and not turn around. He repositioned himself so that there was no way she could see the tablet's screen, turned off his game and switched to the camera companion app. He tapped the 'connect' button, and a second later his prayers were answered as the image of his room appeared in crystal clear HD color quality.

He saw himself lying on bed in the background, but was immediately drawn to the image of his sister in the foreground. She had just finished sorting out her clothes and toiletries on the futon, had already taken off her pants and was now taking off her top. He quickly tapped the 'record' button and had to stifle a gasp as she casually lifted the garment higher and her bouncing tits were unleashed. My God she was beautiful, with her milky white skin and her big dark nipples. He knew it was wrong but he could look at this for hours, and certainly would do so the moment she left.

He kept staring at her magnificent tits, mesmerized. He thought about everything he wanted to do to them: cupping them with his hands; sucking on those big nipples; rubbing them with baby oil and sliding his big hard cock between them. The list just went on. They swayed gently as she moved around. Just when he thought it couldn't get any better, she slowly bent over and rolled her panties down while her big tits were dangling below her.

She got up; her voluptuous body was now completely exposed to the camera. He frantically operated the camera's pan and zoom controls to get a better close up view of her pussy. He had dreamed about it for so long now, about licking it, fucking it. Now he had to capture every detail of it before she turned around or covered it somehow.

When the camera was zoomed in, he got exactly that: glorious detail. Unlike the natural bush he had seen in the shower that one time, she was now completely shaved except from a little triangle of black trimmed hair above her clit. It was pointing downwards, as if giving directions. Her outer lips were relatively small, but her inner ones were bigger and sticking out. It was the hottest thing he had ever seen. His dick got so hard it almost started to hurt a little.

After drooling over the image of her pussy for a few seconds, he noticed a little flickering of reflecting light right below the triangle of hair as she moved. At first he wasn't sure what it was, then when he saw it again he realized it was a little metal ring. He couldn't believe it; his sophisticated, never stepping out of line sister had shaved her pussy and gotten a piercing through her clit! She must be really getting in touch with her wild side there on campus. There was no way their parents would approve of this, but then again how would they ever find out.

He zoomed out the camera again to get another shot of her gorgeous tits. He realized he was going to need tissues after she left, and lots of them. When he zoomed out far enough to get her whole body in the frame again he noticed to his shock that she had turned her head around and was looking at him on the bed now. Had she realized what he was doing? Could she see herself on the tablet screen after all from where she was standing?

"What are you doing, little bro?" she asked in a sharp, suspicious tone.

"Nothing, just playing my game" he said, as he quickly switched back to his game.

"Don't you try to trick me little boy, cause I'll notice it immediately if you're trying to cheat! I'm keeping my eyes on you, so you better keep playing that game!" she said in a mock berating voice.

It looked like he was safe.

When she finished getting ready she turned off the light and got under her duvet.

"Night Sammy."

"Night Am."

It was silent for a few minutes before he heard her voice in the darkness.

"You were just bragging, right?"

"About what?" he asked, deliberately acting clueless.

"Oh please, you know exactly what I mean."

"Alright then: no, I was not bragging."

She thought for a moment.

"I've seen it before, remember? It sure wasn't 9 inches!"

"And how long ago was that? Years, right?"

She fell silent.

They had both seen each other naked occasionally when they were kids, but that had stopped once their bodies started growing up.

"I've grown quite a bit since then. I mean the last time I saw your tits they were barely even there, and look at them now!"

"I guess..." she says.

"And besides, you've never seen it hard. The 9 inches only apply when it's hard, as I'm sure you know."

Again, he couldn't believe he's talking about his hard dick and her big tits with his sexy sister, and she wasn't even offended! It must be the Schnapps talking for both of them.

"I still find it hard to believe. I mean 9 inches is just not natural, only porn stars who use whatever it is they advertise in those gross 'grow your penis' spam mails would have a size like that."

"Well I guess sometimes it's true for regular Joes like me too," he replied.

"Maybe you used the measuring tape wrong? Were you measuring using the metric scale side of it instead of using inches? 9 centimeter would be a lot more believable."

"Please!" He said, slightly offended. "I know how to use and read a measuring tape!"

She was quiet for a little while, then he heard her take another sip from the bottle and say:

"Prove it."

He couldn't believe what he was hearing. He had been doing his best to keep his filthy incestuous thoughts out of his mind and have a normal conversation with her, but she really wasn't making it easy.

"How am I supposed to do that?" he asked hesitantly.

"Where is that measuring tape you used?"

"In the top desk drawer?" he said, still uncertain.

Was she really going to do this? She turned on her bed light, walked over to the desk to get the measuring tape, and sat down on the bed again.

"Quickly!" she said excitedly and patted the futon. "Come over before I change my mind!"

His dick was so big and hard that it was sticking up from behind the hem of his boxers already, so he made sure his long T-shirt covered it before he got up and sat down beside her. He grabbed a pillow from the bed and put it in front of his crotch to make sure she couldn't see the outline of his tool yet. He wanted to see how far he could take this. She stretched the rolled out measuring tape between both hands.

"Alright, Mr. Big, let's see it. Time to find out whether you're bragging or not. I bet you there is no way it's going to be 9 inches or over. So put your money where your mouth is and show me!"

"Them's fightin words! Care to make it interesting?" he said, playing on her competitive nature again.

"What do you have in mind?"

"Well, what's in it for me if it really is 9 inches or longer?"

"My admiration?"

"Not good enough."

"Plus I will tell all my girlfriends at uni what a big cock you have. You'll be a legend by the time you go there!"

"That's nice, but I still need more. I'm exposing myself here."

"OK, what do you want then?"

It was probably the booze talking, but now that they had gotten to this point he felt he might as well gamble everything.

"Why don't YOU put your money where your mouth is. Or rather, put my cock where your mouth is."

"Excuse me?"

It was everything or nothing now.

"If I win, you have to suck my cock."

"Oh my god you're such a perv! you know I can't do that, you're my little brother! That's incest!"

"Come on, cocks are cocks, no matter who's attached to them! You said so yourself: you're into really big ones, so you practically can't lose! You either don't have to suck an average cock or you get to suck a huge one. And besides, you don't think I'm telling the truth anyway."

"Right, I still don't!" she replied laughing, but sounding a bit tipsy and more agreeable to the idea.

"So what have you got to lose, nothing really!"

"And what do I get out of this if you do measure under 9 inches, as I still expect you will?"

For a moment he considered offering going down on her if that happened, since it seemed a fair and equivalent counter offer. Then he thought better of it, realizing that she probably still would consider that more of a prize for him than for her. And she would be right. He quickly thought of something else.

"How about I'll do all your chores during this visit?"

Whenever she came over from uni, their parents' "our house, our rules" principle came into effect and she had to help with the trash, dishes, cleaning, and so on. He knew she hated doing all those things, so this might be a good bargaining chip.

"Ha, not good enough! No way is that an equal reward to getting your dick sucked!"

Well, it was worth the try. He thought about what else he could offer her, when she surprised him and said:

"Maybe if you'll do my chores for all my visits FOR A WHOLE YEAR!"

He pretended to consider it for a while, and then agreed to her terms.

"Alright, now show me so I can measure it!"

"Whoa, hold on sis!"

"What, backing out already? An unfortunate case of spontaneous shrinkage perhaps?" she sneered.

"Not at all, but as I said, it has to be hard before we can measure or it won't be fair."

"OK... So make it hard!" she said matter-of-factly.

"Well, it's a bit awkward when there's somebody else in the room, especially if that someone is my own sister! I'm going to need a bit of incentive."

He didn't mention that his dick had been rock hard since the moment she started undressing, but thought he might as well try to get a bit more out of this wager.

"What do you mean, do you want to watch porn or something?"

"I'm sure if you show me your tits it would do the trick!"

"My God Sammy, are you really such a horny perv that you're turned on by your older sister's breasts?" she says, "You should be ashamed!"

"Says the girl who wants to see her little brother's big hard cock!"

"That's different."

"Not to me it isn't. Besides: tits are tits no matter who they belong to, especially big ones." he said. "My cock doesn't see the difference and will get hard regardless, thank you very much!"

She couldn't really come up with any other excuses, though she certainly tried. Eventually she gave in:

"If you ever tell anybody about this I'll kill you!"

"Noted."

She hesitantly started lifting her nightshirt over her head. Her big tits got caught on the fabric and bounced down gently as she lifted it higher, leaving her naked except for her panties. He was already as hard as he could be, so all he did was stroke it more while pretending he was trying to get hard. She sat still, looking a bit shyly at his stroking hand behind the pillow.

While jerking off, he couldn't control himself. He had to touch them. He reached out with his free hand out to her glorious tits.

"Hey!" she said, flinching. "That wasn't the agreement! Look but don't touch!"

"I have to Am, I need the incentive or we'll be here all night."

She pouted a little, then moved back forward and let him fondle her.

He almost came when he felt one of her firm tits and squeezed it, and he had to stop actually jerking off. Instead he just moved his hand up and down behind the pillow, pretending he was still trying to get hard. He rubbed her nipple, feeling it get hard as a direct result of his touch. He pinched it, and she involuntarily let out a breathy high-pitched squeal. Both her nipples had gotten big and hard now. It was such a turn on to see and feel!

"Oh my, maybe I'm not the only one perving on their sibling here after all?" he teased, looking at her raised nipples.

She blushed.

"Shut up."

"I'm going to need a little more, can you show me your pussy as well?"

"Oh come on, this is getting ridiculous! I've shown you more than enough, it's time you show me yours so we can settle this bet!"

Sam thought quickly. He longed to see her actual pussy up close, not just on a screen. He had to smell it and, if possible, touch it. A new idea formed in his mind.

"How about another wager?" he proposed.

"Another one? We haven't even settled the first one!"

"This will be a wager inside a wager."

"What do you mean?"

"How about this: If I can accurately guess what your pussy looks like, you'll have to move your panties aside and show it to me, AND follow any other instructions I might give in order to get hard."

She was thinking for a moment.

"Agreed, and if you guess wrong, you'll have to show me your cock right now and let me measure it, hard or not. No more delays, no more preparation. You better get ready for a year of dishes boy!"

"OK, it's a deal."

"Alright let's hear it. What do you think my pussy looks like?"

"Wait, what's to stop you from simply pretending I got it wrong when I actually guess correctly? I mean, you could just act like it was the wrong answer and I would never know."

"I think we're all adults here, so we should be able to rely on the honor system, right? If you guess correctly I will honestly tell you, I promise."

That was good enough for him, as promises had always been sacred between them regardless of the topic.

"Alright, here goes nothing..."

Sam knew the trick was to describe her pussy accurately enough, without giving away that he had already seen it up close in high definition less than half an hour ago. And that he hadn't been able to get the image out of his head since. He had to use everything he knew about her personality and combine it with a bit of BS. He started:

"Let's see... You're very clever and intelligent, but you've always been a run-of-the-mill kind of girl by nature. Never stepping out of line or doing anything different. You never gave in to fads like crazy hairdos or tattoos. You never rebelled properly, or went partying during your teens. You didn't have any interest in impressing or turning on boys, or any kind of desire to be kinky in any way. So you've probably always kept your pussy all natural, no shaving or waxing except for your bikini line."

Her face showed the hint of a smile.

"But that changed since you entered campus life. You probably started to realize that there's more in life than books and art, and you've been discovering your wild side ever since. I wouldn't be surprised if you have started to rebel against your mild and conforming nature since then, showing yourself that you can be a wild girl too. But of course not in a way that mom and dad could notice, because you're too chicken for that."

"Whatever!" she said, still smiling.

"So I'm guessing you've probably changed your all-natural look down there, and got rid of most of that bush. But you wouldn't shave it completely because you think that's something only slutty girls do, so you probably left a little bit of hair, like a landing strip or a mustache. Actually it's probably a triangle at the top, since you like symmetric geometric shapes so much in modern art!"

Her smile had turned into an unbelieving frown.

"But that's not all," he continued. "Trimming and waxing is just something superficial and temporary, and can easily be undone completely in a few weeks. You wanted to make a bigger statement, something permanent that would stay there for the rest of your life. I'm guessing a piercing, like a stud or a ring through your clit. Yes, a ring, again because you like geometric shapes."

She looked at him incredulously.

"What the fuck." she said slightly disturbed, blushing again and looking distraught.

"Did I get it right?" he said hopeful.

He could see she was trying to figure out how he could have known any of this, but she apparently couldn't come up with anything explanation. Eventually she must have concluded that she was just more predictable than she thought.

"Yes, you got it right you pervert."

"Great! Let's have a look at that shaven pussy!"

She reluctantly spread her legs and pulled her panties sideways, briefly flashing her pussy before quickly moving the panties back.

"Oh no you don't!" he said. "We had a deal, remember?"

Her cheeks turning red and pouting, she pulled it aside again and let him have a closer look. To his surprise, she was visibly aroused. Her bare labia were swollen and wet. His mouth got dry as he started stroking himself again.

"It looks like your mouth is not the only body part eager to meet my cock!" he teased again, breathing a bit harder.

"Oh just get on with it!" she said, visibly embarrassed. "I can't believe I'm even going along with all this."

"A bet's a bet. Can you play a bit with your pussy?"

She looked like she was about to object, but then probably remembered that part of the agreement was to follow all further instructions. She leaned back until she was resting on one elbow, then slowly started rubbing her fingers over her wet pussy.

"Man that looks so hot! " he whispered with a hoarse voice. "Can you moan a bit as well while you do it?"

"Come on Sammy, it's so embarrassing! I never moan when I play with myself, or even when Ray and I have sex. A bit of heavy breathing is as loud as I get."

"Just fake it then, it would really help me out!"
