The surprising, yet not completely unexpected moment you find a tumblr blog with a video of your roommate being spitroasted by several members of the football team.  After several viewings you find your cock is fully erect.  The really “hard” part is holding off shooting your jizz all over the place, wanting instead to save it for your roommate.  Now it’s just a matter of waiting for him to come home, so you can show him both the video and your boner.  Based upon the images on the blog, you figure he will know what to do next.
