Ominan folds his arms and smirks, despite his ruined eyes, as spell after spell misses him by inches, his body drifting back and forth in the air, the orbiting scraps of metal deflecting what he can't dodge. He can feel every attack coming, and he can see where Dahlia is aiming as soon as she forms the intention.
Every spell shatters more of the lab, giving Ominan more objects to wield with his telekinesis.
He smashes the metal together to form crude shapes which he can then drive hard into the floor over goblin bodies, bolting them to the floor and walls. The two bodyguards who didn't balk at fighting him get swept up too, pinned in metal like butterflies on a display board.
He can't get anything that close to Dahlia, though. She's more skilled. Faster. Even with spells.
Ominan continues to move around the lab, dodging the seemingly inexhaustible spellfire from the angry goblin empress, as he tries to force his mind to work through the fog of Corruption glowing purple on his pelvis.
He grabs his cock, starts stroking.
Defeating the empress in combat would be unsatisfying anyway. It would not be a victory, to merely defeat her. He must humble her. And he's aware of how potent his semen is, and how much of it he can produce in a single load. He strokes his cock harder, feeling himself reaching for the edge... the edge that just... he... just... can't... cross...
There is a slightly wild look on Ominan's eyeless face as he realizes: he can't cum. Not on his own. Not with his hand.
With a snarl he uses his telekinesis to yoink one of the goblin girls off the ground. She yelps in pain as the metal bites into her, but Ominan doesn't care. He rips open her clothes and slams his dick into her, using her like an onahole. He cums, flooding her innards with aphrodisiac semen to the point where her belly starts to swell and her eyes roll up in her head as she cums on his dick.
Ominan yanks her off his cock, spins her around, and squeezes. His cum fountains out of the goblin's pussy, spraying all over his orbiting metal and in Dahlia's general direction, guided by telekinesis.
Ominan goes back on the offensive, now that he has a new strategy and a new victory condition.
