Cassia Takes her "Beta's" Anal Virginity

Cassia should have refused. She should have said no, should have suggested they wait, should have insisted on more preparation, more caution. But the potion had stripped away her inhibitions, and Antonia's words had stripped away her resistance, and all that was left was want.

"Yes," she gasped.

Antonia grinned, pouring some oil on herself quickly in preparation.

Cassia positioned herself behind Antonia, her hands on those curved hips, her cock pressing against the tight ring of muscle. The slickness from the oil eased the initial penetration, Antonia’s juices on Cassia’s cock did the rest.

The head of Cassia's cock pushed past the first resistance, and Antonia gasped, her hands fisting in the sheets. Cassia paused, giving her time to adjust, her thumb tracing the dimples on Antonia's lower back.

"Okay," Antonia breathed. "Okay, mistress. More."

Cassia pushed deeper, and the sensation was overwhelming, tighter than Antonia's cunt, hotter somehow, the muscles clenching around her in a way that made her see stars. She went slowly, carefully, giving Antonia time to accommodate her, until she was buried to the hilt.

"You're inside me, mistress," Antonia said, her voice quivering. "You're inside my ass. I can feel you so deep. So full."

Cassia began to move.

Slow strokes at first, pulling out almost all the way before pushing back in, each thrust making Antonia gasp and moan. The tightness was incredible, and Cassia found herself picking up speed despite her intention to be gentle.

"Yes," Antonia urged, giving Cassia the permission that she so desperately craved. "Yes, mistress, fuck me harder. Use this beta's ass. It’s yours."

Cassia's hips snapped forward, and the sound that came out of Antonia was somewhere between a moan and a squeal. She set a punishing pace, her hands gripping Antonia's hips firmly, her cock sliding in and out of that impossibly tight heat.

"You feel so good," Cassia growled, the words tearing themselves from her throat. "Your ass is so tight, beta. So perfect. I'm going to spill my seed inside of you."

"Please," Antonia begged. "Please, mistress, please fill me up. I want to feel your seed. I want to feel it dripping out of me."

Cassia's third orgasm hit her like a thunderclap, and she slammed forward, burying herself as she spilled inside Antonia's grasping heat. She could feel her cock pulsing, each spurt of cum filling Antonia deeper, and Antonia was coming too, her body shaking, her moans muffled by the pillow she had buried her face in.

When it was over, Cassia collapsed forward, her chest pressing against Antonia's back, her cock still buried inside her. They lay there for a long moment, breathing together, hearts slowing, the light casting soft shadows across their tangled bodies.

Finally, Cassia pulled out, and Antonia made a small sound of loss. She rolled onto her side, facing Cassia, and her green eyes were hazy, dazed, unfocused in a way that Cassia had seldom ever seen before.
