Free the Succubus.

Marco looked at the shadow as the screaming increased in volume and pitch, his ears rang and he found he was struggling to focus his eyes. “Alright,” he yelled, “do we do the blood bonding before or after I release you from the binding spell?”

Marco saw the swish of her arse and tail and the smile creep across her face, “Your choice, Master.”

“Fuck!” he screamed in frustration, “If I **** you to blood bond it won’t help will it?”

“Who’s a smart Master?” Daina taunted.

“Fine,” Marco bent over the binding sigil in the middle of the protective circle and scratched at it feebly. “Shit, I can’t get the paint off. Daina, can I please use your claws?” he asked.

“You can,” she purred offering him her hand as she knelt, “and once we are bonded, you can use every other part of me.”

He took her hand and, using her claws, scrapped the paint of the binding sigil away. As soon as the paint peeled up there was a flash of light and energy and the screaming quietened. Still present but less oppressive. “Oh Marco, believe me when I tell you that you are going to very much enjoy me being free. You thought I was eager before, just wait till I show you what I can really to in the sack.”

Marco’s cock responded at her words but he tried to keep his focus, “How do we do this bonding?”

The succubus smiled and for the first time that Marco could remember he noticed her skin was covered in gooseflesh. She noted his look, “I’m aroused, for the first time since you summoned me, I am very aroused. The blood bonding is easy, you willingly drink my blood and I willingly drink yours.” As she spoke she stood up and Marco joined her. She brought a clawed finger to her breast and very slowly cut a line beside her nipple before reaching out and beckoning Marco closer.

Eagerly he took her nipple into his mouth and sucked on the rich blood, there was a tingle of magic there and he felt it start its way into him. He moaned into her breast as he felt her bend forward and kiss her neck and then she bit him, her fangs dug into his flesh and she tasted his blood as he sucked on his demonic lover's breast.

It was less than a minute before Daina pulled back and not long later Marco did likewise with a **** he fought to overcome. “And we are blood bonded,” Daina said pointing outside of the protective circle where no oppressive darkness waited.

“Oh my god, it worked,” Marco exclaimed as Daina embraced him.

“Now I know we have to go and figure out this whole magic being broken thing but I did promise,” she didn’t finish the sentence, instead of a single claw very gently ran along the length of his cock.
