Of course, she belongs to Craig now

Mary Jane stared at the vial in her hand, her heart pounding. "How much do I give him?" she asked, her voice barely above a whisper.

Craig's lips curled into a smirk. "Just a few drops should do it. Slip it into his drink at dinner and by bedtime, he'll be completely impotent."

He pressed closer, his lean body pinning Mary Jane against a nearby tree. His hand slid under her shirt, roughly palming her breast. "And then you'll be all mine," he growled. "No more worrying about that pathetic excuse for a man trying to touch what belongs to me."

Mary Jane whimpered as Craig's thumb brushed over her nipple. "Craig, I don't know if I can-"

"Sure you can, Red," he cut her off. "You want this as much as I do. Admit it - you're tired of faking it with Parker's tiny dick. You need a real man to fuck you properly."

His crude words sent a jolt of arousal through Mary Jane's body. She squirmed against him, feeling his massive erection pressing into her stomach.

"That's it," Craig purred. "Tell me how much better I am than your husband. Tell me what a pathetic little cuck he is."

Mary Jane's cheeks burned with shame, but she couldn't deny the thrill Craig's domineering attitude gave her. "You're so much bigger than him," she whispered. "Your cock stretches me in ways Peter never could."

"And how big is his little dick?" Craig demanded, his hand tightening on her breast. "Tell me, slut. How does it compare to mine?"

"It's... it's maybe five inches," Mary Jane admitted. "Yours is at least twice that. Peter could never satisfy me the way you do."

Craig grinned triumphantly. "That's right. And after tonight, he won't even be able to get it up anymore. You'll be all mine, to use however I want."

Craig's words sent a shiver down Mary Jane's spine. Part of her recoiled at the idea of permanently or temporarily emasculating Peter, but a darker part thrilled at the thought of belonging completely to Craig.

"Now be a good little slut and do as you're told," Craig growled, giving her ass a sharp slap. "I'll be waiting to hear all about it tomorrow."

With that, he melted back into the shadows, leaving Mary Jane alone with the vial of pink liquid. She stood there for several long moments, her mind racing. Could she really go through with this?

Finally, she took a deep breath and made her way back to the cabin. Peter was still hunched over the desk, tinkering with his web-shooters. He barely glanced up as she entered.

"I'm going to make some tea," Mary Jane said, her voice only wavering slightly. "Would you like some?"

Peter shrugged noncommittally. "Sure, I guess."

In the tiny kitchenette, Mary Jane's hands shook as she filled the kettle. The vial of FEM-GX-9 seemed to burn in her pocket. As the water began to boil, she pulled out two mugs and tea bags.

The whistle of the kettle pierced the tense silence. Mary Jane poured the steaming water over the tea bags, watching as the liquid darkened. Her heart pounded in her chest as she reached for the vial.

Just a few drops, Craig had said. That's all it would take to ensure Peter could never satisfy her again. To make sure he could never compete with Craig's monstrous cock.

Mary Jane's fingers trembled as she unscrewed the cap. The scent that wafted up was surprisingly pleasant - a faint floral aroma with hints of vanilla. It didn't smell dangerous at all.

She hesitated for just a moment before tipping the vial over Peter's mug.
