Stay the course.

You try and focus on anything other than sating your lust for the ride. You feel your sister press against you a bit tighter as the train rocks. You look to your side and get a good look down your sister's shirt, and you pull yourself away trying to hold to your goals. She is scrolling on her phone checking her twitter timeline. Her timeline is some people from school that you know and some you don't. Spattered between those more ordinary posts are fashionistas, shows she follows, and rappers. You think for a moment that in her head their is more that bounces around in there than your cock, then she hits her home button and its a selfie of her and your mom worshiping your cock and balls which is to big to fit in the frame fully, quickly bouncing into another app. You roll your eyes and just tilt your head back and stare at the ceiling waiting for the ride to end.
