[Shirokurousa (Sugiyuu)] Machihazure no Seijo-sama Daisuki na Onee-chan wa Boku no Shiranai Otoko no Mono [Benri] [Full Color]

Whenever a noble visitor arrives at the orphanage, the big-breasted nun the young narrator adores as his big sis quietly disappears—and pressing his eye to the shed wall, he discovers her stockinged thighs spread for a dark-skinned, muscle-bound stranger whose oversized cock teaches her untouched body what it was truly made for. Swept from pride in her holy legacy to breathless servitude, the saintly sister soon calls the man 'Master,' trading blowjobs and paizuri for the donations that keep the orphan children fed, every hidden encounter pulling her deeper from the boy who worships her. Years later he still stares at the sky with a hole in his heart, while the closing pages reveal where she ended up: heavy with child, her impregnated body draped in silk as the nobleman's kept woman.
