[Rifuru] Boku-tachi wa Onee-chan no Toriko - We are captives of My sister Ch. 3 Zenpen

A voluptuous older sister with soft, heavy breasts and a devastatingly inviting body has her younger brothers completely captive, and a seemingly innocent offer to swap rooms pushes their affection into dangerous new territory. Alone in her scent-soaked bed with his sleeping sister's lush curves inches away, one shy younger brother finds his restraint crumbling as temptation turns to trembling, feverish groping in the dark. What starts as tender gratitude after school quickly unravels into a sticky, intimate night where sweet sibling devotion blurs into helpless, aching obsession.
