Explanations.

Myria laughed to herself at Dew and Cecilia's predicament. Mostly at Cecilia. Who would have thought that the prude paladin would be caught bumping cunts with another woman? It. Was. Glorious.

"Maybe you should explain yourself, wizard!" Cecilia barked. Oh yes, there was that righteous indignation Myria knew so well. "You're keeping some mysterious arcane pit in your home? Something that has untold... power?" She flushed a little at the word "power" Myria noted. "And you've fucked our companion!"

"I'll have you know that Myria threw herself upon me," Tarquin said. "She was the instigator, not I!"

"Even so," Dew said, more calmly than Cecilia, "That glow has immense power. It seems to have mind control properties."

That strange glow coming from the pit... Myria's eyes were oddly drawn to it as it pulsed steadily. She was still coming down off the high of sex with Tarquin, but that glow seemed to fill her with a new wave of arousal... Before she could stop herself, she found her fingers trailing down to her vagina.

"I didn't put the glow here," Tarquin said. "I built my house around it. To study it." Myria began to rub her fingers around her womanhood, lubricated by her own fluids mixed with Tarquin's semen still dripping from her slit.

"Explain, then," Cecilia said. "What do you know of it?"

The others weren't paying Myria much mind, so she kept herself busy. She sat by the glowing pit and started rubbing herself in earnest.

"The glow is from deep, deep below," Tarquin was explaining. Myria bit her lip to stifle a moan as she flicked her clit. "It is some kind of font of erotic magic. It is what makes the toads so sex-crazed, and its power has mutated them, altering their venom to transfer its effects. It is using the toads to spread its own power." Myria gasped as an orgasm struck her.

"Do you mind, Myria?" Cecilia said. "This is important!"

"Mmmm.... nope," Myria moaned. "I don't mind at all!" She inserted another finger into herself and another orgasm followed the first.

"You see?" Tarquin said. "The glow's power has already taken her. And both of you, it seems."

"What about you?" Dew said. "You live next to it. How are you not changed by it?"

"I've warded myself," he said. "I cast a lot of protection spells on myself every day. Even so..." He indicated to his own groin, where his cock had returned to stiffness.

"Mmm... when do they wear off?" Myria said between gasps. "I'd love to see you cut loose a bit... a bit... a BIT!" She squealed as another orgasm rocked her body. "Oh, fuck it, bring it here!"

She crawled over to Tarquin and wrapped her mouth around his shaft.

"Myria!" Cecilia shouted.

"Bite me," Myria said. "Or bite Dew. She won't mind." Then she returned to sucking Tarquin's cock. The mage did not protest.
