I Got Reincarnated in a (BL) World of Big (Man) Boobs manga volume 2 features story and art by Tsukiji Nao.

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. Now a reincarnated Nagare must try to dodge his way past a barrage of BL scenarios which 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 in this latest volume?
