Incest Sex Story: Chapter 2 - Every week, Thomas gets to fuck his sister. Together, they roll two dice, and depending on the total sum, he gets to receive either a handjob, a blowjob, her pussy, or her ass. The only catch? He only gets to do it for sixty seconds, after which his chastity cage goes back on to prevent him from masturbating or touching himself elsewise. And faced with such a short time, it isn’t long before his frustrations begin to get the better of him as he is teased beyond his endurance.

An eternity seemed to pass before the next weekend came around again.
Sitting at his desk at school, Thomas drummed his fingers absentmindedly against the surface. It was Friday, the last period of the day, and in another thirty minutes or so the bell was due to ring. Mrs. Parkins, their English teacher, droned on at the front of the class. Her chalk squeaked silently across the blackboard, and he tried to tune out the irritating sound it made. Somewhere in the back of the room, he could hear someone listening to music on their earbuds again.
Staring out the window, he suppressed a yawn. It was as if time had slowed to a crawl. Another half-hour before class let out, he thought miserably. And then after that, another two or three hours before it was time for his usual weekly unlocking. His chastity cage pressed up against his thighs, and he shifted in his seat as he tried to find a more comfortable position. Better to not think about it for now though, and just focus on the present.
Besides him, his best friend Jake leaned over to whisper in his ear.
“Hey dude, look over to your right,” he said.
“Why?” asked Thomas.
“Just trust me,” said Jake, “You can thank me later.”
Thomas sighed. Well, it wasn’t as if he had anything else better to do. Turning around, he looked, and it took him less than a second to spot what he was supposed to be seeing. Sitting two rows in front of him and one seat over was Ashley Stafield, one of the girls in their class. Blonde haired, blue eyed, and just a little bit shy, from what little he could remember about her, her grades were just about average at best. A little pretty perhaps, but hardly special among the dozens or so other students in their class.
Of course, that was hardly why Jake had pointed her out to him. Even if they were both currently bored out of their minds. No, there was still a method behind the madness, because as plain as the rest of Amanda was, she was still miles ahead when it came to two very specific categories. Namely, the two giant pillows she had attached to the front of her chest. Like a pair of mountains, he thought, if mountains were even an appropriate name for such things.
Idly, he felt his eyes wander across her body. He just couldn’t help it. C-cups at least, maybe even bigger, while the rest of the girls were still a full size or two behind. And even worse, she just had to be wearing her usual pair of skintight yoga pants today that showed off every last inch of her considerably well-formed bottom along with the clearcut ridges of her panty line. It was too much for him to stand. Going by the perfectly logical rules of high school horror films, she would have fit right in as the barely legal cheerleader who ends up getting gangbanged by the entire cast at the end of the third act.
Thomas frowned. Hollywood had really been going downhill lately, which was the only reason why he had thought of the comparison. For now though, he had other things to focus on. Like following the outline of her bra as it ran up over her shoulder and down her back. Between his legs, he felt his member twitch another fraction of an inch upward, and he bit down on his lip.
“She’s hot right?” said Jake.
Thomas groaned as he forced himself to agree.
“Like, image those tits,” said Jake, “What I would give to have a couple of minutes alone with those things.”
He stared in fascination at the holy muse of his desires. Thomas looked too, but with considerably less intent. Not that he didn’t think she looked nice, but with his dick locked up as it was, even if he did manage to end up alone with her behind the locker rooms, it wasn’t as if there was much for them to do anyways but stand around awkwardly.
For a moment, he tried to think about how it would turn out. The entire situation seemed like something out of a bad dream. More than likely, she would simply laugh at him the moment she saw his cage. Or his tiny little pecker, squished down like a sausage as it twitched uselessly above his sack. And as much as he wished he could do something about it, it was just simply impossible without the key.
Thus, it was more with a silent sense of appreciation that he looked over at the way her lips nibbled at the end of her pen. Like looking at the cakes through the window of a bakery. A feeling that only grew worse as Amanda leaned forward to tie up her hair. The back of her shirt rose up, and looking even closer, he could just make out the elastic waistband of her panties peeking out from the gap in between.
Pink.
“Man, that’s one hot piece of ass,” said Jake.
Well, so much for staring platonically. Thomas groaned again, shaking his head to snap himself out of it. He couldn’t afford to do this right now, least of all before the weekend of all things. And besides, it wasn’t as if he hadn’t seen plenty of girls in their underwear before along with their tits. Sort of. Mostly just one pair of tits. The fact that they belonged to his sister wasn’t something that he particularly felt like specifying.
