It breaks the spell.

The naga chanted to itself, swaying hypnotically back and forth. Shairi was still frantically masturbating, but a part of her was fascinated by the sight of the snake-spirit’s magic. Another part of her was terrified as to what the effect of that magic would be on her.

The naga’s fangs glowed as it finished her spell. Then it struck forward, biting Shairi again, right on her cunt. A fang sunk in on either side of her dripping slit. Shairi screamed at the intoxicatingly intense mixture of pleasure and pain, crying out madly as she orgasmed again and again. She felt a particularly sharp sensation as the spell Meritheir had placed on her virginity shattered.

The naga smiled. “Yesss… the ssspell isss lifted…”

“Thank you!” Shairi gasped, her mind full of all the ways she could satisfy her lust now the barrier was gone.

“Now…” the naga hissed. “What shall I do with you?” Its tail touched Shairi’s womanhood again. “No… not thisss… I am tempted, but I shall be ressstrained…”

Shairi moaned with disappointment. The naga laughed.

“No,” it repeated. “A ssslutsss virginity should be broken by a cock. Asss it happensss, I have a cock in mind. He will owe me much for letting him have sssuch a sssweet treasssure…”

The tail moved down, touching Shairi’s anus again. “I shall inssstead enjoy claiming thisss…”

The tail moved up Shairi’s body, caressing her pussy and circling her breasts, before stopping in front of her mouth. Shairi knew what was required of her. She leaned forward and began to suck on it, licking across the scaly surface. She lavished on the tail all the attention she would on a penis, and wondered if the naga was sensitive enough to appreciate it.

Her heart was thumping with excitement, and no little fear. She’d always planned to lose her anal virginity when Meritheir’s spell was undone, but she’d greeted the prospect with some trepidation. Now, her mind fogged by the naga’s magic and venom, she was eager to submit, and her main regret was that the serpent wasn’t going to take her maidenhood as well.

Once she’d made sure the tail was well lubricated with her saliva, the naga moved it again to her arsehole. Shairi cried out ecstatically as the point worked its way into her. As the length of tail inside her widened, she began to cum helplessly. The tail began to wriggle inside her, stimulating the inside of her arse. She had never imagined such pleasure. With one final, immense orgasm, she passed out.

Shairi awoke, naked and smelling of sweat and sex, to find the naga’s tongue tickling across her body. “Mmm…” it hissed. “You are ssso deliciousss…”

It reared up. “I am going to ssseek the one who will be the firssst to ussse your sssluty little pussssy...”

Shairi shivered in anticipation. She was sore all over, especially her arse, but it felt wonderful.

“I have warded thisss cave with ssspellsss,” the naga said, slithering to the entrance. “Do not attempt to essscape, or you shall sssuffer…”

Why would she want to escape, Shairi wondered as the snake left, when her new mistress had given her such pleasure?

“She’s really done a number on you, hasn’t she?” Queiss said, emerging from the corner she’d been hiding in.

For a moment, Shairi wondered what she was talking about. Between the naga’s venom and its magic, Shairi’s will had been temporarily overturned. But she was a sorceress, and the future Witch Queen! She was not so easily bound! She knew she had to take this opportunity to escape.

But oh, it had felt so good… Since she was in control, would it be so bad to linger here a bit longer, to experience that pleasure a bit more? It was very tempting…
