The succubi now shrank back and left the heroine and the Hell Lord alone. At first, Mephisto had to grip Sue's hair and force her head up and down on his rigid cock, but soon he realized she was blowing him willingly and he took his hands out of her golden locks. Susan Storm-Richards had always been a talented cocksucker but thanks to her recent experiences, she was now an expert. She deep-throated the foot long pole effortlessly, her throat muscles gripping the scarlet dick like a fist, her tongue lashing at the underside and playing around the bulbous tip, giving the Hell Lord sensations of incredible pleasure.
Sue, for her part, had surrendered herself to the moment. The good part of her was still fighting against all this, but the rest of her - the seductress and whore that was slowly taking control and being fueled by the Seed of Sin - reveled in all of it. She loved nothing better than a big hard cock in her throat and this was the biggest and hardest she'd ever had. She kept eye contact with the wickedly grinning Hell Lord as she bobbed up and down on his glistening shaft, humming and moaning to heighten his pleasure. He patted her head like a faithful dog and why not? For now, she was his bitch. Sue smiled at the thought, and continued sucking the massive cock.
Mephisto chuckled to himself as he felt himself build towards climax. He knew that his Dark Seed had its own arcane properties and was looking forward to seeing the effect it would have on the proud and haughty heroine after he had pumped a load of it down her gullet.

Elsewhere in Mephisto's infernal realm, in a deep cavernous space where no demons currently lurked, there was a sudden rush of wind and a blast of blue-green light. It faded, revealing the other members of the Fantastic Four, Doctor Doom and Dr Strange!
