Lesbian sex, of course

"What would I have to do?" asked Krystal.

"Me, for starters," Adijah replied, brushing her hand across Krystal's cheek.

Krystal gulped and shied away. "But I'm not a lesbian," she protested.

Adijah shrugged. "No one's perfect," she said. "But not to worry. I like straight girls. Of course, after one night with me you'll never be straight again."

"So instead of being in Gorkon's harem I'll be in yours? Some deal that is," sneered Krystal.

"Serve me and you'll be more than just a harem girl," Adijah assured her. "Much more. You'll be a soldier in my army, a succubus with power in your own right, forever young and beautiful."

"And still stuck in Hell," countered Krystal. "Hard as this may be for you to grasp, I don't like it down here."

"Well, it's not really 'down.' That's just the word we have to use for you three dimensional types," replied Adijah. "But that's getting off the subject. You want to get back home?"

"More than anything," said Krystal.

"Done. Join me and I'll send you back. You'll have to split your time between that place and this, but you can serve me in both. Use your new power to seduce women in your world, and their ecstasy will fuel my sorceries here. While you sleep your soul will return here to fight my battles and frolic with my demon wenches. Once we have crushed Gorkon we shall reshape this realm to our liking, a paradise of perversion and lust, and those who took service with me in the begining shall be its nobility!

What say you?"

"What happens if I say no?" asked Krystal in a small voice.

"Then I'll send you on your way," said Adijah, her shrug lifting her impossibly perfect breasts closer to Krystal's face. "Gorkon's frustration at your escape will still amuse me. You'll probably end up another demon's ****, but who knows? You might even find your way out of here in a few years."
