Though he'd discovered the pleasures of masturbation many months before, it still took him a minute to realize that what Dawn was doing was the girl version of what HE did. And with that understanding, there wasn't a damn thing he could have done to prevent his cock from tenting the front of his shorts! Even while his mind was reconciling the differences between what he did and what Dawn was doing, his eyes were taking in the view his older sister was presenting to him: her medium-sized breasts with small, dark areolas and nipples and the dark wedge of hair where her fingers were busily dancing at the top of her readily visible cleft. Jeremy could only stand there, mesmerized by the sight, as Dawn continued to pleasure herself.

It was only when he heard her release a soft groan and saw her body arch off the bed that Jeremy realized that she'd found the release she was after – and that with nothing to 'distract' her, she'd easily spot him looking at her. He quickly pulled his head back and closed the door – slowly and gently pulling the doorknob enough that it latched. Then it was a quick dash to the bathroom for him, where it took him only a minute to find his own sexual release. When his cock has softened enough, he was able to angle it down and relieve the pressure in his bladder. He waited a couple of minutes before flushing the toilet so that Dawn would think she'd finished before he came down the hall; then it was back to his bedroom – where he had to jerk off again before he was relaxed enough to think about being able to get to sleep.

Jeremy was distracted all the next day as he thought about what he might be able to do to not only try and get another chance to see Dawns body, but watch her touching herself again. His preoccupation with what he'd seen the night before did cause him simultaneous problems for nearly the entire day, though: not only did all of his teachers have to keep after him to pay attention in class, but he spent virtually the entire day with a raging hard-on and no chance to DO anything about it.
