[Zinkurou] Futanari Holy Knight and the Cage of Sperm-Draining (2D Comic Magazine Futanari Energy Drain Mesuzao Kyuuin de Energy Shasei Haiboku! Vol. 1) [imanoterone]

Holy Knight Eris, a Level 82 futanari blessed by god to single-handedly overwhelm armies of monsters, is captured and sealed inside a living cage of succubus slime and hungry tentacles designed to drain her holy energy through forced ejaculation. Her big-breasted, armored body is bound and milked without pause as clinging tentacles suck at her futanari cock, her sensitive breasts and crotch tattoo pulsing with aphrodisiac pleasure while a teasing demon girl and her writhing tail drive her toward helpless, ahegao-soaked climax after climax that strips her levels away. With each draining spurt leaving her weaker and more corrupted, the promise to be kept forever as an obedient, semen-spent pet grows sweeter than resistance.
