all the fic I wanted to write but didn't

It was bound to happen eventually - Jack happens across some porn. It can be on the internet, a skin mag, or something else. That detail isn't important. What is important is he bluntly asks Dean about it. And then wants to recreate what he saw. Can be as sweet or filthy as you like. Consensual or dubcon preferred for this prompt rather than outright noncon.

The only skin mags Dean would leave lying around would be titty magazines, not actual porn. But Jack could be openly looking at one, and Dean sees him, asks him if there's anything he likes. When Jack's like, um, no, does that mean there's something wrong with me? Dean's like, no, and then drops his voice and asks Jack if he'd prefer something like this (pulls out one of Sam's Men's Health mags). And Jack likes. There's discussion over whether Sam likes looking at men with few clothes on, Dean's like, um, I think he legit reads the articles. Jack asks Dean if he reads the articles, and Dean's like, hell no, I just look at the pictures. But not while Sam's looking, he's afraid I'm going to get his books all sticky. And Jack's like, oh, yes. I can understand his concern. Things can get sticky.

Awkward, and then, Jack's like, Dean, do you look like this (muscley dude) with hardly any clothes on? And Dean's like, um. Looks down at himself, looks at the dude in the mag who's all cut and shit, not quite. And Jack asks him if he could see.

Dean's like, oh shit. Okay, so he could just get Jack some porn. But learning from porn at this stage in his development could be detrimental. He might go out and actually hurt someone cos gay porn can sometimes be quite rough. Best to ease him into it with someone who knows what Jack is capable of.
