You realize that you have a massive erection
From Create Your Own Story
You look down and see a huge bulge, through the blankets. You realize that you have a massive erection and you are really horny. You grab your computer and find some good porn and start masturbating. You get really into it, but, after a while, you get the feeling that you're being watched. You look through the crack in the door, to see who it is.
