Sit down on the couch with roommate

You sit down on the couch with your roommate, Ben. He's a fairly short person, maybe 5'4, and is of normal build. There's nothing fancy about him, but he's still in decent shape, and isn't ugly by any means. He's an extremely nerdy person, and he wears glasses. You imagine there are a few women who would find him attractive, but he's been in a rut lately, its hard to get him to go out.

Its not at all cold in the room, so you are not sure why Ben has a blanket on. You guess he probably just thought about sleeping on the couch below his bunk. Opposite his bunk is your bunk, and under that, is the TV. Sometimes he's just too lazy to climb into bed, and other times, he likes to fall asleep watching tv.

You notice his jeans not far from the couch, casually tossed there - which you find as odd because Ben is a very neat person. He always tosses his old clothes in the hamper in his closet. You're still quite drunk, but you understand that means he's likely in his underwear under the blanket.

You've seen Ben in his underwear before, but tonight, you are curious as to what he's been up to. Jeans on the floor, blanket covering him up, and TV on. Ben must have been watching a porno. He'd likely been jacking off right as you were coming in the door!

Excited at the prospect that you could have caught him in the act, you are suddenly becoming quite horny. Your dick rises in your pants, and you realize that Ben will notice if you sit there too much longer.
