7 Days of Incest/Day 1/Whip your Cock Out
The pleasure is just too great not to enjoy it but you want more, you need more; its been forever since you have gotten this close to anyone, even if it is at the expense of your sister. Your vision has gone red with lust for your sister's ass, all thoughts and pretenses about the music now lost in the haze. You have her right where you want her and struggling, screaming, and swearing is the most that she can do against your grip... but you don't care.
As difficult as it might be while restraining her, you skillfully manage to unbuckle your pants and quickly whip your dick out. Even now, you're shocked that Rose hasn't noticed the feeling of something large down there... but in this day and age, teenagers are often blind or ignorant to the things they're not focused on. Still on the ground, you line your dick up with her skirt... but then an idea hits you, why stop at just the skirt? With her still seemingly distracted, you could probably slip your dick under her skirt and rub against her panties... but it is risky.
On one hand, without the extra fabric between your dick and her rear, it was far more likely that Rose to figure out what you are up to sooner rather than later; but on the other hand, if Bayley or Nichole were to walk in right now and see you forcefully pleasuring yourself on Rose's skirt, you'd be in big trouble. At least with your dick under her skirt, the risk from that particular problem would be mitigated.
