Shinmai Kenja-chan no Oppai Kaizou Dungeon -Kiyowa de Hinnyuu no Shoujo wa, Inran de Bak

Novice sage Kuno Hughes takes on a monster subjugation quest, but upon entering the cave lair, she triggers a trap releasing pink aphrodisiac smoke and is captured by tentacles. The monster binds her, strips her, and subjects her to intense sexual stimulation, including breast milking and vaginal penetration, which induces multiple orgasms. After being injected with drugs, Kuno's body is physically altered with significantly enlarged breasts, nipple rings, and a magical crest on her abdomen that forces her into a state of continuous arousal. Despite struggling with her newly modified body and its extreme sensitivity, she ultimately succumbs to her desires and returns to the dungeon to remain with the tentacle monster.
