Her desires are too strong.

She approached the cage as she ran her finger between her slick cunt lips, she wanted a cock, she wanted to fuck, to be fucked. As she walked closer to the demon the new tongue residing in her mouth snaked out and lapped at her still human nipple. It sent an electric shiver through her body.

She didn’t try and sneak up to the beast, instead walked purposefully, it tensed slightly as she neared but as she reached her hands around it’s waist to grab it’s cock, still slick with their combined juices, it let out a pleasant moan.

She stroked its dark red member while kissing it’s back, then slowly moved to in front of the beast. With no foreplay she mounted the book, her arse sitting on the pages and spread her legs. The demon needed no further encouragement, it stepped up between her legs, the worm like protrusions seeking out her slit, still wet with his cum. The beast bent its back steeply to kiss at the mouth where her nipple once was. Beth moaned in response as the demon’s thick tongue delved into her breast, then it slowly pushed itself forward.

This time the demon’s entrance was easier and soon he was pushing against her cervix. It was at this point that Beth discovered something curious; the pain in her abdomen was a transformation of her cervix and she now could control it, and the tightness of her cunt to some degree. As he started to pump his cock in and out of her wet cunt, Beth opened her cervix to him, just enough to feel him stretch her again. Moments later she was bucking with pleasure as the demon bottomed out. His balls sat against her arse, his bulging stomach lay on her pelvis as he cock head battered against her insides. The pages of the book under har arse ripped as she moved back and forth across the open pages.

He eyes rolled back in pleasure and lust, she knew she, and her lover, would not last long. He pulled his goat like face to her by the chains wrapped around its horns and kissed it, delving her tongue into its mouth. Both of them moaned in desire as she kissed him, sucking on his lower lip as she felt him push harder. If felt like he was trying to fuck even deeper but it just drove Beth on.

Soon she felt him shuddering as his claws bit into her shoulders, drawing blood she was sure, and knew he would cum, she knew he would be back to his task as soon as he was able, but with him distracted she had a chance.

She reached deeply into herself as she grabbed his face for another kiss. Then as she felt him tense she whispered two words, “Velntis arum.” She said it quietly but with intent, a spell not normally used, one dangerous to those who used it and those it was used on.

She felt his forceful puls of cum like a jolt in her womb as the demon felt a jolt of its own. Distracted with pleasure it could not defend itself from the spell. A strong bolt of lighting passed from one of Beth’s hands to the other, straight through the demon’s head. The spell had cost her, it had exhausted her to draw on the demonic energies within her, including the fresh energy the demon was depositing along with its cum.
