Downfall/Ease your own thighs 2
From Create Your Own Story
You slightly adjust the angle of your hip, tilting the upper part forward. You then ease your thighs, just enough so that they do not clamp Julianne's leg any more. Without the support, your body is pulled down by gravity, pressing your labia against your Mother's thigh. The effect is noticeable immediately. Not only does the sliding feel much more intense, but the vibrations of the car are transferred to your pussy as well. You anxiously wait if your mother says something, but when a while passes without her making a remark, you relax and start to enjoy the ride (is this what they call a joyride?). As it is, you think you have gotten a hint of why people sometimes do things they shouldn't have... it worries you, but at the same time not enough to stop what you are doing. Getting away with something seems to be as much an incentive as the action itself.
It takes you a while to notice that you seem to rock back and forth a bit more than before. First, you blame your new stance for that, but then you realize that your mum has slightly loosened her grip around your belly. This allows you move another inch or two along her leg, but also gives more lateral leeway. You look to the side. Your mother is looking out of the window, apparently miles way. She must be too busy thinking about the check-in for the flight and all the hassle that comes with it. A sharp right-left turn of the cab throws you around. You instinctively turn your fingers inwards to stem against Julianne's leg to prevent at least the second sideway movement. Can you believe that cab driver?
You check up on your mum again. She is still lost in thought.
