You have

The sun had finish setting and you hadn't gotten a chance to turn any lights on inside the house. Now, as your body and mouth are held useless by the arms of the intruder. The room is has become very dark and you can hardly see around you. There is only a dim glow from the streetlamp down the road. You tense up in fear. The intruder seems to notice it. "Keep quiet and I won't hurt you. I thought the house would be empty when I saw the car pull away. I'm just here for valuables."

Before you can even think of yelling, the intruder deftly slips a cloth gag into your mouth and ties it sharply behind your neck. He roughly pulls your arms behind you and ties them together. "Get on the ground" He commands. You lay down on your stomach while the intruder ties your ankles together. Unable to scream, unable to move, fearful tears start flowing down your cheeks. You glimpse over your shoulder as the intruder stands up and turns down the hallway. Its hard to make out in the light, but he is tall, muscular, and quiet as a mouse as he slips throughout the house.

You start to worry about what valuables he's going to take, when a shocking thought flashes through your brain. "Fuck! he's going to go in my room and see all my porn! Oh no!." Panic floods through your brain. You start to struggle against your bonds, hoping to work yourself free. Unfortunately, the intruder knows his knots and its impossible for you to get loose. You manage to roll yourself to your side and glimpse into the doorway. Shockingly, you can see the intruder silhouetted. "Fuck he was quiet! How long had he been standing there?" lightly backlight in the dark you, you can get a look at his face. But you can get a sense for just how big he is. He must be at least 6'6". The intruder approaches you slowly, menacingly. Your heart thunders in your chest.

"So," he says "I found your computer."

"Shit" you mumble through the gag

"And I couldn't help but notice what you have been looking at. A boy like you spends all his time watching videos on men fucking men. I never pegged you for a bottom. Lots of videos of tiny asses being fucked by big thick cocks. Is that what gets you off? Answer me"

You nod slowly, still trying to make out any facial features of the intruder.

"Well, then I broke into the right fucking house." You flinch as his rough hand reaches out and runs the length of your lower back and down onto your firm ass. Because I just happen to have a big thick cock that would love to fuck your little ass."
