BL rec: Itoshi no XL size
So here's a random rec for an ongoing BL manga that is not entirely porn.
The main kink in the story is size kink, which is why I clicked but wait! That's not why I'm reccing it (at least, not solely why).
The premise is university student Yamamoto (black hair) joins the Sake research society at uni to meet girls and lose his virginity. Unfortunately it turns out the society is very serious and academic and full of guys. At a club meeting he gets very drunk and bemoans his virgin status to another guy (Kobayashi, brown hair) who is also a virgin (even though he's incredibly handsome), because he has a huge dick and no girlfriend has ever been able to handle it. With the best drunk logic Yamamoto decides he'll help his new friend regain his confidence by letting him fuck him.
So that's the porn, and it's really fantastic porn to be honest. The scanlators decensored things, and they used some great fonts for the speech bubbles. The art is also really beautiful as you can see.
The main draw for me is the relationship between the two guys, which is very cute. In chapter two there is some great denial going on, with Yamamoto imagining Kobayashi with a wife and family, but oh no, why does his chest hurt? And Kobayashi saying he'd like some more practice so can they do it again? And both of them in total denial that they might actually like each other romantically and still thinking they need girlfriends. I really can't get enough of these kind of tropes.
It's an ongoing manga, and you can buy the Japanese version in the magazine Gateau starting here in November:

The title is 愛しのXLサイズ by 重い実 and you can read a sample by clicking on the orange button a little further down.
Otherwise there are scanlations under the title 'My lovely size XL' or 'Hashi no XL saizu' (don't really agree with the pronunciation of 愛し they went with).
Would recommend if you want beautiful art, hot porn, or a funny and sweet romance.
