[Hanami-ga Saku (Sakurai Toki)] Onna Kishi Kurono Chikubi Choukyouki [desudesu]

Captured knight Chrono learns her training will span twenty long years as a doting maid snaps a heart-shaped padlock collar around her throat and promises to take very good care of her. Slime-drenched tentacles swarm her bare breasts, suckers latching onto her swollen nipples to pump and milk her mercilessly until the lactation flows — all cheerfully harvested as food for the rest of the tentacle brood. Torn between her desperate vows to escape and rescue her queen and the maid's sweet, smothering devotion, every page tightens the leash on her nipple-training ordeal.
