He decides to help her... eventually

"Get off me!" Eilwy's black robe flapped around her slender legs as she kicked at the troll.

The troll grunted, easily batting the enchantress's feet aside and lowering its weight onto her to hold her in place. Then it gripped neckline of her robe and ripped it down with one mighty yank, the seams tearing and splitting easily in the troll's large hands.

There was a moment's pause. Then Eilwy, wide eyed with surprise at being suddenly naked except for a small pair of black panties and leather boots, squealed.

"Great Odric's Beard," Dirk muttered admiringly. Eilwy's small, pert breasts were gorgeous, and her legs slender and smooth. She looked small and cute, which was not something he imagined was usual for the great enchantress.

Meanwhile, the troll was enjoying itself. The more the witch struggled, the more fun it was to tease and grope her. But it was nearly time to get down to the serious business. Gorge licked its lips in anticipation and reached down for Eilwy's panties. The enchantress thrashed and kicked, momentarily frustrating it. But the troll just grinned and ran its wet tongue over Eilwy's face, leaving it glistening with spit. "Ew!" she cried, eyes squeezed shut in disgust, and flailed at the troll, who immediately reached down to yank at her unprotected panties again. This time Gorge successfully hooked its fingers into her delicate waistband.

Dirk weighed his options. Do nothing and watch a lady lose her dignity on the troll's massive cock; or intervene and have a very thankful, pretty mage on his hands.

Or, possibly, a very angry troll, he thought grimly. But still, the thought of rescuing the powerful enchantress was more appealing. Surely she would give him something pleasant as a reward? Three wishes, or perhaps something more... intimate?

Hesitantly, he picked up a rock. It felt heavy in his hand and had sharp edges. He hefted it, getting used to the weight.

"No... you filthy bastard! Get off me!"

The troll had finally gotten its full weight on the helpless enchantress. Her legs were wide open and wrapped around it's muscular body, kicking helplessly in the air, panties hanging from one ankle, whilst her small fists beat on its back.

Dirk tossed the rock in the air and caught it. Then he pulled his arm back in an arc and unleashed the rock at the troll in a ferocious volley.

And missed.
