I Got Reincarnated in a (BL) World of Big (Man) Boobs manga volume 1 features story and art by Tsukiji Nao.

“I just…wanted to…touch boobies…"

Nagare Otokawa was an otaku loser obsessed with breasts. He tragically died never knowing the feel of the sweet, sweet bosoms he'd craved all his life. Little does he know, his wish is about to be granted in a way he never would have expected.

Nagare gets reincarnated as a handsome guy and quickly realizes that he’s living in a (BL) world full of sexy (male) beauties. Even so, he sets out to find and squeeze the bust of his dreams. He does, in fact, end up with his face planted deeply in some luscious cleavage, but to his dismay, it's the magnificent pecs of the super-muscular class delinquent, Ryuji Onizuka!

Now Nagare must try to dodge his way past the barrage of BL scenarios that hurtle into his path. Will he persevere and get the busty girlfriend of his dreams, or will he end up falling for the all-man--yet temptingly bodacious--Ryuji?
