Changes

The two continued to screw for another five minutes when Mary pulled away. She changed position so that she was lying on her back. David quickly resumed his fucking. As the two screwed, Mary through gasps stated, “I need to corrupt your brother now, baby. I need you to wait fifteen minutes before joining us. Can you do that.”

David’s new mind understood what she was saying and why she needed to corrupt his brother. He even desired it now. He briefly thought of taking Monica, Devon’s new squeeze. The sweet scenes the idol showed him of massive orgies and corrupting innocents filled him with desire to do it as well. David continued to pound into Mary’s pussy until he felt them both come once again. He then pulled out and laid back on the bed next to her. In his now deep enticing voice he stated, “Fifteen minutes will be hard to wait, but I will try my love.”

Mary crawled on top of his now massive form and kissed him passionately before responding, “Good, I want you to be ready to DP me. My former self always had fantasies about being double stuffed. I think its time to make it happen.” She kissed him again before sliding off and walking out of the room with a seductive shake of her derriere.

The spare room was on the opposite side of the house near the garage. As Mary walked through the darkened house Titan rubbed up against her leg whining. As she reached down to pet him, he began to hump her leg. All animals are the same, Mary thought to herself as she gently pushed Titan off and petted his head. She whispered, “Sorry boy, you need to wait, as I have to do something first. But I will have a treat for you soon.” She pet him again and walked on through the house. She moved through the door that was ajar and shut it quietly behind her.

Devon was barely awake and had already come once more. He was tired enough that he did not realize she had walked in. She could see that his sheets where cast off his sweaty body and due to her pheromones his cock was still hard even after coming. Devon had been unable to quench his desire. Mary smiled at this as she moved quietly to the bed. She crawled up on it like a hungry cat.

Devon’s eyes shot open as he realized someone had just gotten on the bed with him. He could barely see Mary’s face in the dim moonlight from the window. He was partially shocked to see her as prim and proper as she had always been; not to mention how she was usually stand offish with him. Then his ego kicked in as he thought how she could not resist him anymore. He smiled at her thinking to himself that he had finally conquered her and would taste this forbidden taboo. The desire to partake in his brother’s wife filled him with more lust.

Mary could feel his desire grow and his cock even grow a little. She took his cock deep into her mouth thinking to herself how she still hated this man but liked his body. She just needed to separate the two. She deepthroated Devon’s cock making him gasp as his head fell back against the pillow. He had never imagined that Mary was so good in bed. He was growing envious of his brother by the second, thinking how his brother had been with this woman for nineteen years. He had always been surprised that as high school sweethearts they had made it this long, but now he could see why. Mary was amazing. In less than a minute he was coming inside her mouth. Mary marvelled at the feeling of Devon’s cock growing a few inches inside her throat.

Devon’s mind filled with perverted thoughts and lusts. He was amazed that after three orgasms tonight, he was still hard. The act of an affair with his brother’s wife was definitely exciting him far better than viagra, he thought to himself. Devon almost felt sadness as Mary let go of his cock. He then became elated as he saw her moving up to position herself over his cock. He felt sheer bliss as she lowered her tight flower down around his cock. It was the best he had ever felt he thought. He could not help himself, he blurted out, “Oh good, this feels like heaven. I have never felt a pussy feel so good. You are fantastic Mary.” He tried to lean up and kiss her but she pushed him back down on his back.

Devon paid it no mind as she rode his cock, quickly gaining speed. He felt another climax building and tried to keep himself from coming. He did not want this to end. Mary dropped her glamour and raked her claws lightly across Devon’s chest. As it was a light scratch, Devon felt a slight pain that only added to his pleasure. He moaned out not comprehending that Mary had changed. He did not even notice his own body beginning to change as his skinned darkened.

Mary having had an idea before she started this, focused her thoughts on Devon’s developing form. Devon skin was growing mottled and a little flabby as it began to shrivel. She could feel Devon trying to resist coming as he wanted to last. She reached down and took his face in her hand as she hissed, “Fill me with you sinful seed, breed me, like the harlot I am. Show me how much of a man you are.”

Devon’s mind realized several things. Mary looked completely different and drop dead gorgeous. She looked like a mythological Succubus and the thought made his lust increase. He also realized that he needed to come and breed her as she had commanded. He then realized that despite feeling like he was about to come he could not quite do it. He tried to raise his arms but they felt like lead. He paid it no mind as he relished the pleasure from her riding his cock. The tingling through out his body only further enhanced the intense pleasure he felt.

Suddenly Devon felt more weight on the bed and saw a form rise up behind Mary. It was to dark to tell who until he leaned forward and Mary leaned against him wrapping her arms back and around his neck. Devon saw another Demon that held many of his brother’s features. He realized that this creature that looked like his brother was also now mounting Mary. She was being fucked in both her holes now. He could feel his demonized brother’s huge cock inside Mary. The feeling blew his mind. All that mattered was he needed to come. Somehow he knew if he came, he would become like them. Strong virulent and sexual beyond his wildest dreams. He wanted this.

Mary felt Devon about to come and give his soul to the idol. She reached back down and took Devon’s head in her hands as she asked, “Do you give yourself to our god? Do you relinquish your pitiful soul?”

Devon did not hesitate, he screamed out, “Yes, yes, oh fucking yes bitch. Take my soul. Make me like you.” Devon came with mind-shattering **** as his orgasm washed over him. He felt his soul pull away and sink into hell as his body filled with an infernal heat that filled it with desire and corruption. Suddenly he noticed the feeling growing weaker. His senses seem to weaken. He opened his eyes to see the Succubus Mary now close enough to kiss smiling wickedly at him. He knew something was wrong.

Mary growled, “You were always so untrustworthy. You belonged to my master long ago with all the sins and treachery you have committed. Why would I reward you? Especially when you would betray me later. I have a better plan for you and your body.”

Fear gripped Devon’s mind as all feeling of his body left him. The delicious feeling of euphoria was gone, all he could feel was a sinking feeling as the darkness began to grow around him. He began to feel as though he was falling into blackness. The last thing he saw before pure darkness was Mary’s evil grin. Then suddenly there was a reddish light and an intense heat. He fell to hell and felt the anguish of all those he had hurt over the years. He knew he would spend his eternity suffering instead of feeling sexual pleasure.

Mary pushed Devon’s head down into the jelly like mass that had been Devon. Now a mass of tentacles where flying all around her. She pushed David back off of her and reached her magic out towards the door. It opened as she called out, “Oh Titan, come here boy. Time for your treat.” She willed the mass below her to still as Titan rushed into the room to her. She could smell her pussy-juice on him. He had been in the master bedroom licking her and David’s nectar from the sheets. David watched fascinated from the shadows wondering just what did she have in mind.

Mary coaxed Titan up onto the bed despite his fear of the mass. She pushed her magic into his mind and clouded his senses as the mass began to wrap around Titan. It began to pour into him though any available opening, even the very pores of his skin. Then Titan began to grow and change. His mass became less dog-like and more humanoid. After several minutes a nine-foot chiselled humanoid muscular frame with a large dog’s head squatted before her. Mary released the creature’s mind. Suddenly, the bed slammed to the floor finally giving out from the weight atop it. Mary laughed as she watched the new creature in front of her open its fiery orange eyes and large maw.

Mary mentally reached out and stated, “Titan my pet, change to you new human form please.” She watched as the creature got out of the bed and standing beside it began to shrink and change again into a form very similar to Devon’s former self. This creature’s hair was much longer and darker and its face a bit longer but similar to Devon. She then verbally asked, “Can you tell me who you are?”

The creature opened its mouth and stated in a whine that changed into broken syllables, “I...am…Titan mistress.”

Mary was elated as her plan had worked. But she needed to see one more thing. She verbally asked, “Can you still become your former canine self.”

Titan closed his eyes and slowly he shifted to a dog. The transformation took twice as long as his human transformation but was successful. He then growled in a barely understandable voice, “Does this please you Mistress?”

Mary giggled as she stated, “It does immensely. You will make a very loyal spy, soldier, and sex toy my pet. Now change back to your true form please.” Titan took about a minute to change to his nine-foot form. Mary marvelled at his although furry, very muscular form. She also noticed how his pouch seemed oddly shaped. She reached and fondled it and saw not one but two large dog-like cocks that were easily a foot in length and as thick as a baseball bat grow from the pouch. Mary began to salivate at her creation.

David moved in close and whispered, “Your imagination knows no bounds my love, he is magnificent.”

Mary glanced at the time and saw she still had two hours before the event that Melissa had told her about. She turned her back to Titan and raised her ass. She told him to mount her and fill both her holes before she took David’s hard cock deep into her throat. The three fucked for another hour turning the room into disaster as the bed became shredded in their sexual fervour. Mary stopped the **** two and stated, “We need to go to my college. My sire has a lovely little soiree planned. Plenty of sweet little tail to corrupt.” Titan howled as David began to laugh in his deep voice.
