[Minase Yowkow] Shuurare Kudou no Madoushi (2D Comic Magazine Futanari Energy Drain Mesuzao Kyuuin de Energy Shasei Haiboku! Vol. 2) {Hennojin}

Captured mage Monica awakens in a sealed cell beneath Vinias Castle to find her kouhai Roro waiting—not the sweet apprentice she remembers, but a corrupted, cock-bearing servant of her captors, eager to demonstrate the tentacle torture that broke her. A writhing drain monster coils around Monica's own thick shaft, and her confidence that she can shrug it off crumbles as it milks her toward climax with maddening, teasing strokes. Worse still, the creature plays a cruel game of denial, stopping her just short of release again and before wringing burst after burst of magic-rich seed from her to feed its ever-growing tentacles.
