[Mokuyama Hito] Onee-chan Tensei! Junyuu Isekai Seikatsu | Reincarnated Big Sister! Breastfeeding Sex Life in Another World (COMIC Luxuria Melt Vol.01) [Sonarin迫]

A reincarnated elder sister discovers that her enormous, rapidly expanding breasts offer a strangely healing comfort to a kitten-eared boy in another world, and his eager dependence turns her caretaker role into a charged domestic intimacy. As he nurses, her body fills with milk and her embarrassment gives way to the pleasure of being needed, while their cramped, spare room becomes a private refuge from the unfamiliar realm. The cover’s promise that onee-chan’s boobs will make him feel better captures the hook: a fantasy of caregiving, bodily transformation, and a brother-sister bond growing bolder with every gulp.
