Cassia is Ridden by her "Beta"

Before Cassia could respond, Antonia was pushing her backward, guiding her toward the bed. Cassia's legs hit the edge of the mattress and she fell back onto the sheets, Antonia following her down, their bodies tangling together in a mess of limbs.

"This beta needs to do better," Antonia murmured, straddling Cassia's hips, positioning herself above Cassia's aching cock. "This beta needs to find a way to drain her mistress completely. To leave her satisfied. To prove her worth."

She lowered herself slowly, the head of Cassia's cock pressing against her slick opening, and Cassia's hands flew to Antonia's hips, gripping them tightly.

"Is this what you need, mistress?" Antonia asked, sinking down another inch. "My cunt around your cock? My beta hole clenching around you?"

"Yes," Cassia gasped. "Heavens, yes."

Antonia sank down the rest of the way, taking Cassia's entire length in one smooth motion, and both of them groaned at the sensation. Cassia could feel Antonia's inner walls gripping her, hot and tight and perfect.

"Oh, mistress," Antonia breathed, beginning to move, her hips rocking in a slow, circular motion. "You feel so big. So hard. I can feel you in my stomach."

She leaned forward, bracing her hands on Cassia's chest, and set a rhythm that made Cassia's eyes roll back in her head. Up and down, up and down, her cunt sliding along Cassia's shaft with a wetness that spoke to how much Antonia was enjoying this too.

"This beta loves this," Antonia continued, her voice growing breathier as she rode. "Loves having her mistress inside her. Loves being used. Loves knowing that she's the one making you feel this way."

Cassia's hands moved from Antonia's hips to her breasts, cupping them, thumbs brushing over her nipples. Antonia moaned, her rhythm faltering for a moment before she found it again, her head falling back, her dark curls cascading down her spine.

"Harder, mistress," Antonia said, her green eyes finding Cassia's. "Use me. Fuck your beta like you own her."

Cassia's hips bucked upward, meeting Antonia's downward strokes, and the sound of their bodies colliding filled the room. She could feel her second orgasm building already, the potion pushing her toward release faster than she could resist, and Antonia's dirty talk wasn't helping.

"You're going to make me come, mistress," Antonia gasped, her movements becoming more urgent. "Your beta is going to come all over your cock. Is that what you want? For your beta to lose control while she's riding you?"

"Yes," Cassia growled, and the word came out rougher than she intended, more alpha than she had ever sounded before. "Come for me, beta. Come on my cock."

Antonia shattered.

Her body convulsed, her cunt clenching around Cassia's shaft in pulsing waves, and she cried out, a sharp, high sound that was almost a scream. Cassia watched her come apart, watched her head fall back, watched her breasts bounce with each spasm of her orgasm, and it was the most beautiful thing she had ever seen.

But she wasn't done.

The potion still burned in her veins, and her cock was still hard, still aching, still **** for release. Antonia slumped forward against her chest, panting, her heart hammering against Cassia's ribs, and Cassia's hands came up to cup her face, tilting it upward.

"Again," Cassia said.

Antonia's eyes widened. "Mistress?"

"I'm still hard." Cassia's voice was low, demanding, nothing like her usual careful tone. "My beta hasn't finished her task."

A slow smile spread across Antonia's face, and there was something like pride in her expression. "No, mistress. I haven't."

She pushed herself off Cassia's cock with a wet sound that made them both shudder, and then she was rolling over, presenting herself on all fours, her back arched, her ass raised, her dark curls spilling forward to curtain her face.

"This beta has another hole," Antonia said, looking back over her shoulder, those green eyes bright with anticipation. "One that's even tighter than the first. One that's never been used before."

Cassia's breath caught.

"Would my mistress like to sink her cock into my virgin ass this time?" Antonia asked, her voice dropping to a whisper. "So that this beta may have her mistress's cum in all three of her holes?"
