She's unable to stop herself

"Oh, god...!" The blonde girl groaned to herself, as she was clearly too close to her climax to be able and stop herself right away. Instead she just shut her eyes tight again, seemingly trying to ignore her father's presence, while continuing her frantic masturbation in front of the bathroom mirror.

She'd already lost a bit of tempo however, and wasn't quite able to regain her balance, which meant that she was left hanging in the borderlands between immense pleasure and utter frustration. Soon she'd seemed to forgotten completely about her surroundings, and was moaning and whimpering in desperation, while obviously trying her best to get back on track again.

Meanwhile Jack could barely believe his eyes of course, and he found himself unable to move from the spot, while Kimberly continued expressing those mixed feelings in front of him. Some part of him knew full well that he should've just left her alone at once, but at the same time he couldn't quite bring himself to turn his back on such an erotic scene like this one.

Eventually he seemed to regain some control over his senses at least, even though he still didn't know what to make of them, and for a while he was struggling just to keep his pulse from racing like crazy. There was little he could do to keep himself from becoming increasingly aroused by the whole situation however, to the point where he was nearly about to just walk right in to the lovely young woman standing in the room in front of him.

In fact he was almost surprised that his feet hadn't started moving yet, and for a split second he couldn't even remember what would make it such a terrible idea to begin with. It was all true though, that the girl reminded him a lot of his former wife, and Jack could feel his body itching with lust as he pictured the same situation, with any other woman than one of his own daughters.

It would've been a lot easier for him to make a decision if that was the case, but now there was a lot of restrictions that were holding him back, even if they didn't seem quite as solid as he'd always believed up to this moment. Especially as the young woman could clearly be in use of a helping hand by now, if she hoped to finish her business before she was completely exhausted...
