She got to work quickly.

Madam Tempest watched hungrily as Isaac kicked off his shoes and pushed off his pants. Her hand went to his cock, a single touch making him throb and drawing out a shuddering gasp. She chuckled as she gently stroked him, her touch ghosting over his length. Her eyes burned, glowing bright. “You are… intoxicating, Isaac.”

“Th-thank you,” Isaac muttered, his eyes flicking between hers and her hand on his member.

“Please, dear, don’t leave me out.” When Tempest kissed Isaac again, her full lips met his properly, tasting of wine. She pulled back after a moment and licked her lips. “You’ve looked me up and down a dozen times since walking in here, and a dozen times earlier today. Don’t you want to touch, rather than see?”

Isaac took her advice, reaching out to cup her breasts. They were soft, smooth, heavy, and she hummed contentedly as he ran a thumb over her dark nipple. Madam Tempest smelled like petrichor and something floral, like a bed of flowers after a storm. She nudged Isaac even closer, his head between her breasts, so he complied, laying his head against her chest. Her hands roamed up Isaac’s body, feeling every inch of him with large, deft hands.

“So small, you humans,” Tempest murmured as she held Isaac in the curve of her body, her long tail moving to create a loose circle around him. “Yet so powerful. So strong. So… passionate.” She again took hold of Isaac’s cock, stroking him with practiced motions.

“So I’ve been told,” Isaac replied. He pressed kisses to her soft gray skin, along her chest, down the curve of her breast, to her nipple. He let his own hands roam over her, the transition between soft skin and smooth scale, eventually finding her slit, already wet.

Tempest gasped slightly, smiling wide. “Would you like a taste?”

Isaac nodded, shifting his position. He slowly licked up the length of her slit, pausing to suck on her clit. She yelped, then laughed. She moaned and laughed softly as Isaac ate her out, quietly enjoying the attention. She put a hand on Isaac’s head, fingers tangling in his hair as his tongue delved into her pussy.

“You’ve got practice, human,” Tempest said, voice breathy. Her grip on his hair tightened as Isaac pulled back long enough to spread her with his hand, then delved back in again, tending to her as best as he could. She’d probably had hundreds of people service her, he just hoped he was adequate in comparison. “You’d even compete with Graham.”

Isaac blushed harder and reached up, sliding his hand along her torso until he reached her breast, finding her nipple and pinching it. It got the intended reaction, a tiny cry from the powerful woman. Her hips rolled forward, pushing her pussy against his mouth. The tip of her tail coiled around his ankle, squeezing tight.

After time enough that Isaac’s jaw started to get sore, Tempest shuddered and tugged on his leg with her tail. He paused, and with one hand she pulled him up. She held his face in her hands, her eyes glittering. She kissed him, strong and hungry, the tip of her tail trailing up his body to gently caress his cock.

“Enough teasing,” the woman said as she pulled away, lips glistening, “I need you to fuck me.”

The way her voice rumbled in her chest, the way it echoed in Isaac’s head… he felt a distinctly arcane web drape across his body. Her eyes were glowing green, and that deep verdant light was trickling down her arms, into her hands. Tempest looked lost in a haze of some kind, a fanged smile on her soft lips. She kissed him again, then her tail wrapped his leg and pulled him back down.

Isaac hastily aligned his cock with her slick pussy, and before he had a chance to move, a hand against his lower back pushed him in. Tempest hummed, pleased, and Isaac sucked in a breath. Her inner walls clamped down on him tightly as he started to thrust, each movement drawing a further gasp and cry from Tempest. She clenched and squeezed his cock, her hips rolling slightly, expert motions coaxing him to climax.

Something about her was actively draining his energy. Maybe it was that spell she was now casting, or something due to what she was feeding off of him, or something else entirely, but where Isaac would normally last a while, his energy and endurance were rapidly fading. With every passing moment, Tempest’s body was softer, more arousing, the sensations more intense and harder to resist. His thrusts became erratic, her moans got louder.

Tempest put a finger under Isaac’s chin, lifting his face so her gaze could meet his. “You are delicious, Isaac.”

Isaac nodded as he kept his hips moving, trying his best to hold back his quickly-approaching climax. “Th-thank you, Madam Tempest.”

“I want to taste your seed, dear. Would that be alright?” Her breath was hot, heavy, her voice low and dripping with lust.

“Yes, of c-course,” Isaac murmured.

Tempest pulled Isaac away, laying him back. She leaned over his crotch and his twitching cock, extending a long tongue. Her tongue wrapped his cock as she closed her mouth around him. A sensation like a million miniscule sparks danced over his member, and he barely had time to tap a warning on the side of Tempest’s face before he came. He throbbed in her mouth, spilling seed for a few long moments, the longest wave of climax he’d ever felt. At the same time, she shuddered, letting out muffled moans, as if she were also cumming.

Finally, after they were both relaxed again, Tempest lifted her head up and licked her lips. “Perfect, Isaac. Just perfect.”

Isaac found himself drowsy, a heavy weight resting on his body. He’d never felt so utterly spent like that before. “Thank you for… for that. I hope it was satisfying for you… Madam Tempest…” He struggled against the weight of sleep, blinking rapidly.

“I think a little too satisfying.” Tempest gently touched Isaac’s cheek. The green glow was gone, now she just looked slightly worried. “I haven’t fed like that in decades. I apologize, dear. Get some rest. I will take care of you.”

Isaac nodded blearily. The only thing he wanted in that moment was to rest.
