Jeremy had been more than a little afraid of what his sister would say or do when he finally pulled his hands from in front of his erect cock; but when he heard what she'd said, he was considerably more comfortable about having her looking at him. From gym classes at school, he knew that he was a little bit bigger than a lot of the other guys, but had no idea if Dawn had seen bigger. He was watching her as she looked at him, and he couldn't miss the way her nipples got longer and the peaks of her breasts puckered. When she leaned over to look at him some more from different angles, it didn't take long before he could detect the unique aroma that told him she was getting excited. In turn, that got him more excited, too…
Dawn was examining Jeremy's cock – fascinated by how hard it looked, and the veins and things she could see running in it – when she realized that he was getting a little bit longer, and that his erection was pointing even MORE towards the ceiling. It was pretty darn obvious that he was becoming more aroused… but why? She hadn't even done anything to herself yet! When she considered what was different between then, and before the changes she'd seen, the only difference she could think of was that she'd felt herself getting excited. Then, in a sudden flash of understanding, she knew that seeing her excited was making him excited – which only served to ratchet her arousal even higher.
More than anything she'd ever wanted to do, Dawn wished she could just lean forward and kiss the end of her brother's cock; it simply looked that good to her. But she just knew that if she did anything like that, he'd absolutely freak out, and she'd never get to look at him again. And it was only because she'd promised that there wasn't going to be any touching – yet! – that she was able to resist the urge to trace every square millimeter of the surface of the erect manhood before her. The idea of being able to cup his balls in her hand, and feel how warm and heavy they must be… Dawn felt her breasts get even tighter at the thought of it. Even as she was recognizing what was happening to her, she saw Jeremy's cock grow again; that was all it took for her decide that it was most definitely time to give herself some relief from the pressure she could feel building in her loins…
Jeremy saw his sister sit up again, then move to sit farther on her bed. Looking at her, he could see that her breasts were tight, and her nipples crinkled and erect. Farther down, her vaginal lips were dark and the area between them already glistening; the aroma of her arousal was thick in the air. When he was finally able to drag his eyes back to her face, she looked into his eyes as she hesitantly told him "I… I want to watch what you do and… how you do it. You said you like seeing me and what I do, and I want to see you, too. Don't worry about it if you, uh, squirt on me as long as you don't get any, you know, there. Just let me know before it happens, okay?"
He couldn't believe that he just heard his sister not only say that she wanted to see how he jerked off, but tell him that it was okay for him to get his cum on her. The way he was feeling right then, they'd be lucky if it didn't all end up on the wall! Still, he understood what she said, and readily voiced his agreement. On hearing that, Dawn lay back before pulling her legs up and resting her feet on the edge of her bed. Still looking at him, he watched as she deliberately spread her legs so as to give him the best view yet of the area between her thighs. Without her saying anything about it, he could also tell that she was waiting before starting to touch herself so that he could have some time to really look at her. He started to lean forward so he could do just that before realizing that she might not be ready for him to look at her that closely just yet. But when he lifted his head to look at her, she easily understood what he was asking without him having to say a word; she just gave him a strange smile and nodded that it was okay.
Even as he was moving closer to the area of interest, he watched as her vaginal lips got a trifle longer and the area between them became a little shinier. The sight baffled him for a few moments before he realized that she liked having him look at her; shortly on the heels of that, it came to him that she might also like it when he was watching her, too.
But before he could start following up on those thoughts, he was close enough to be able to see some of the details of his sisters anatomy. Her vaginal lips turned out not to be as thick as he'd first thought; instead, they were a bit longer – it looked like they were curving inward, toward each other. With his closer and better view of her, he could also tell that she was a lot wetter: able to see between her labia a little more, it was apparent that she was even wetter farther inside. It was all he could do to keep from reaching out and collecting a little bit of her juices on his finger so he could find out what they felt like; following that, he decided that he wanted to learn if they tasted as good as they smelled! But he didn't want Dawn feeling like she could just start grabbing his dick, so he managed to keep his hands to himself. However, there wasn't anything to keep him from trying to memorize the way she looked; he knew he'd never forget how she smelled…
Dawn had been surprised when Jeremy started to lean over so he could look at her better; she was pleased when he stopped to think that perhaps SHE wasn't ready for him to do that, and looked to see if she had any objections. The thought of it actually turned her on, and she readily let him know it was okay. She saw when his hand started to move, and was vaguely disappointed when he didn't actually touch her. She knew he could see (and smell!) how excited she was; knowing that he not only wanted to look at her, but that he'd be able to smell her even more had her feeling it as she got even wetter inside. She found herself wondering if he found her parts as attractive and sexy as she did his. She thought to ask, but didn't want to embarrass him and screw up what was turning into a meeting that was a whole lot more than she'd hoped for!
Dawn waited as long as she could for Jeremy to get his fill of looking at her, but her excitement was growing by the second; when she finally couldn't stand it any longer, she let him know it was time to get things going again by moving her hand down and running her fingers through her pubic hair. After he raised up again, she could see that he was both disappointed that he'd had to stop, and eager for what he knew was next.
Jeremy had no idea how long he looked at Dawns pussy. What he did know was that when he saw her hand ease toward her pelvis, it was entirely too soon. But the realization that she was ready to start – and that he could take care of his own needs while he was watching – were more than enough to compensate. When he was standing again, Dawn was watching him closely as she slid her hand lower and curled her middle finger so that the tip of it slipped between her vaginal lips and traced a path upwards toward the little bump he'd seen at the top. When her finger passed across it, he heard her release a soft moan. She repeated her actions several more times, and the moan was a little louder she did it; that was all it took for Jeremy to decide that he really wanted to find out what that little spot was. Until then, he had plenty of other things to occupy him – such as watching what his sister was doing right in front of him.
