Jolie told her to stop, demanding she also take her top off and continue naked.

"Stop!" Lisa heard her sister bark out a command, and before she even realized what she said, Lisa had flinched in surprise "Take your shirt off."

"What? Why!?" Lisa was taken aback, what was the point? Being filmed bottomless and masturbating wasn't any worse than doing it naked, it only served to increase Lisa's risk of being caught.

"Because I said so, you look real awkward doing this with your shirt on." It was a lame excuse, Lisa knew this because it was an excuse she would have used on Erica, it was simply done to shove the fact that you were in charge in your victim's face.

Lisa gritted her teeth in irritation, she knew that her sister was playing her, but she was powerless to fight back at this point, not when she already had some **** material on her, and she needed to get inside to deal with it before it's exploited.

Giving up, Lisa angrily whipped her shirt off, revealing her voluptuous breasts and hardened nipples to her sister, then gave her last piece of clothing up, watching it disappear inside the house.

"Continue." Jolie nodded, and Lisa went back to fingering her wet pussy, but now that she was naked, she found her other hand reaching up to tweak her nipple, she fought hard not to let any moans out, she didn't need the neighbors catching a glimpse of her now that she was a bit more exposed.

* Someone comes up the driveway of their house

* the kid next door (whom Lisa humiliated several times already) sees her from over the fence.

* Lisa manages to cum before there're any other surprises.
