pullout the front of your panties and aim his cock at the inside crotch (but disaster strikes)

Instincutally you pull the front of your soaked panties forward and try to aim Sam at the crotch of your panties, but in your panic you aim him at your pussy by mistake. In you're mix of pleasure and consentration jerking Sam off, you didn't realize that the small vibrator had fallen out of you're pussy its battery having died cause it wasn't charged the night before. Just as Sam was about to blow what might be the biggest load of his life, disaster struck.

The bus hit a massive pothole, shaking everyone in the bus violently, Sam lost his balance crashing forward into you knocking the wind from your lungs. It took you a minute to catch you're breath when the gravity of the situation hit you, when Sam fell towards you, his soon to explode cock entered your **** pussy, the sensation too much for him, Sam ejaculated load after massive load into you're fertile pussy, bucking every shot.

You sat there stunned unsure what to do, the bus pulled to a stop at the school and people started leaving the bus, Sam having finished pulled out stunned as well at what had happened. The urge to not be late to class overrode his higher faculties, he stuffed his cock back into his pants, zipped up and offered a silent sorry before leaving the bus. With not much to do you pull your panties backup grabbed you're backpack and got off the bus, Abby not far behind grabbing the vibrator as she passed.
