Ryan tormented her to break her will.

As a demonic being, Marlissa didn't need to eat or sleep, at least the way mortal humans need to. Ryan left her bound to the pentagram, alone in the darkness of the old, abandoned church for a few days before he showed up. He didn't bother asking her if she would agree to the pact but simply fucked her until he was about to cum, pulling out at the last moment and let his semen splash outside of her magical prison.

Over the course of three weeks Ryan continued doing this even when Marlissa pleaded that she would agree to his pact so that he could fill her belly with his semen and quench her sexual hunger.

"Please master," the succubus whimpered, watching Ryan walk towards the pentagram. "I will agree to the pact!"

Ryan didn't say anything but crawled between her outspread long legs and nudged his cock into her tight snatch. Marlissa closed her eyes and enjoyed the sensation of her pussy around his cock. After a few minutes the succubus expected that Ryan would pull out as usual but instead felt the first thick stream of semen splash into her womb. Like a thirsty man finding an oasis in the middle of a desert, Marlissa's pussy was hungrily milking Ryan's cock of all the sperm his balls could muster.

The young archeologist collapsed on top of Marlissa, reveling in the feel of her soft body against his. "Master?"

Ryan pushed himself off of her and reluctantly pulled out. He walked over to his pants, on the floor outside of the pentagram, and grabbed a folded piece of paper. He unfolded it in front of Marlissa and she looked at the contract, written in the ancient Sumerian script.

"Speak out loud the terms and agree to them. In exchange I will free you from the confines of the pentagram," Ryan demanded.

Any other demon would want to tear apart their summoner but a succubus instead would want to fuck her summoner to ****, draining him of his life ****. Marlissa believed that Ryan wanted her because he could have dismissed her anytime after having his way with her and summon another succubus. Now she wanted him even more.

"I agree to the pact and will be your companion for the rest of your natural life, master." Marlissa began reciting the pact in ancient Sumerian, words not heard in nearly two thousand years.

Ryan started to shiver in excitement. Not only did he summon a demon but a succubus! And she agreed to his pact!

"The pentagram, master," Marlissa said. "I'm still bound to it."

"Oh, right. Yes!" Ryan skimmed through the tome to find the appropriate page with proper words to deactivate the pentagram causing the candles in the room to flicker.

Marlissa found her wrists and ankles no longer magically bound to the pentagram and stood up, stretching her large bat-like wings. With the grace of a ballerina, Marlissa stepped past the lines and runes of the magic circle. The sensation of freedom was almost orgasmic to her but the hunger was more overwhelming. She needed to feed the hunger and the only way it could be quenched was sex. Her green eyes flared with lust as she approached her new mortal master with a grin.
