Asmodeus sensed the smell of sex in the air. He followed the sensation walking patiently down the street surpassing a couple of houses. After a right turn he saw them. A couple saying their goodbyes on the porch.

They were definately not having sex, but the demon knew that he was rarely wrong. It just had not happeneded yet and he was right. After a long and passionate kiss he saw how the man put his hands on the woman's shoulders and pressed her down on her knees. He didn't use force, Asmodeus could smell the obedience in the air probably that was why he was drawn by their smell at the first place. 

The couple felt safe, not knowing that they not only are not alone, but they were actually being observed by a higher entity. The demon watched as the 20 year old woman devoured passionately the cock of her boyfriend. Asmodeus was content with the sight. The blowjob suddenly was not a blowjob anymore. The woman was face fucking herself on the cock in front of her taking it as deep as possible. The man was not even guiding her head down. She did not need direction, the direction provided by the hard shaft in her mouth and throat was enough - she was not to deviate from her mission. 

Asmodeus could sense the great potential in the girl. He loved the smell of obedience and submission. He wanted her soul. He was growing impatient and just about when he thought of interrupting them the man started cumming. For a normal person it was impossible to see the throbbing cock ejaculating - not only it was dark at midnight but the woman had taken it all inside her oral cavity. This was not a problem for Asmodeus. Even from where he was standing he could clearly see and feel everything. He saw how deep the cock was actually placed inside of her throat - every drop of semen was bypassing her mouth and was delivered very deep - almost directly in her digestive system. So unnaturaly deep that in fact she gagged and started coughed out some of it through her nose.

"See you tomorrow" the man lifted her and kissed her gently "You have cum on your face"

"I know" She smiled silently and kissed him back. 

Asmodeus watched as the couple kissed goodbye. The man walked away as the woman entered in the house. Asmodeus used his opportunity and as a shadow followed her inside. She locked the door, left her purse on the shelf next to the door and entered through the second door to the right. It was the kitchen. This is when Asmodeus took once again his physical form.

The woman was startled. She looked at the man who had suddenly appeared out of nowhere in the middle of her kitchen. Asmodeus looked as her cum covered mouth opened in surprise. It looked very natural for her to be like that, he thought. Probably she had had a lot of cocks there. He looked her in the eyes. But this was not how he would proceed. He looked her in the eyes. He had different plans. Probably he would put his cock inside of her mouth, but he would save it for later. He looked deeper, this time through her eyes.

"I understand" she suddenly said as she calmed down. She was ready for the signal.

When Asmodeus snapped his fingers, she did not hesitate. Without a verbal command she undressed completely. Her boyfriends cum was still visible on her lips and chin when she got herself on the table and lied down presenting her cunt and ass to the demon.

"I am whole tous my lord. Take my pussy!" she eagerly announced herself available as she lifted and spread her legs, keeping them steady with her holding them with herarms.

Asmodeus rubbed his erection against her clit alongside her cunt lips a few times. The depravity was contagious and her cunt got over aroused immediately inviting him with its wetness.

"This is not what I am after today" he didn't say this. It was only a thought, but she felt it deep inside her. Her face twisted  with expression of surprise and fear, and her mouth once again open wide in protest, but her consent was already given. 

A few seconds later Asmodeus shoved his cock violently inside of her anal opening, but the woman could swear she felt like she was being split in half even before his dick penetrated her body. The initial shock made her feel dizzy and she lost her awareness. The next thing she remembered was her still keeping her legs open as the demon was already pounding vicously her asshole.

Asmodeus knew very well what he was doing, he immediately had felt how his cock not only reached the promised barrier but it had already violated it. Suddenly her whole body was shaking in wild and completely uncontrollable convulsions. The body possesed by the demon had a cock way bigger then the average size for a human - about 2 inches in diameter and the impressive 7 inches in length. Yes, the woman struggled when the penetration started,  but the physical dimensions of the cock inside her asshole were the cause only for the initial pain. The current state of her body, sweating and writhing uncontrollably almost like a seizure, was the aftermath of the metaphyisical size of the demon cock - a penetration which went way deeper beyond the established physical boundaries. Asmododeus looked at the 20 year old woman squirming on his cock. He knew how severe and life changing the consequences would be for her but he couldn't care less as he continued his vicious rampage.

The relief was moments away. Asmodeus had seen this many times, but he still find it fascinating. The woman froze for a brief moment, her eyes full of fear rolled back in their orbits. The demon had not only penetrated her soul but now she felt his impending orgasm. Demonic cum was a toxic and defiling substance and in the moment when the first drop touched her very essence, her body began to shake in convulsions again, this time even more violently. He held her tight, pushing her even further down on his cock. Asmodeus was simultanously protecting her vessel from physical harm and also increasing his own pleasure. By the time the last drop of his semen was delivered in the depths of her body, her mouth had started to foam.

After a few more tremors the woman's physical vessel completely eased as she loost consciousness still fully impaled on his cock. The demon moved her body up and down several times easing his way out of her asshole. Once he was out the the hole gaped obscenely as thick black semen started dripping on the table beneath her.

Asmodeus lit a cigarette - one of the few human habits that he actually liked. He observed her. The woman looked like a sleeping person who was having having nightmares. She shived and suddenly moved a few times while the thick cum was still oozing out of her anal tract. Asmodeus was not only familiar with the sight but he also found it aspiring. Complete and utter defilement this would be the result and he loved it. The woman would be a different person after she woke up or even not a person at all. Asmodeus smiled alone in the dark room observing the miracolous effects of a demon cumshot deep inside of the human soul. Particularly devastating when accessed through the anal gateway of the body.

The woman woke up as suddenly as she had lost consciosness. She lifted her upper torso from the table leaning on her hands as she looked around. She saw him sitting on the chair and she dropped down from the table and made a few steps towards him.

His thick black sperm was still oozing from her anus going down on her inner thighs as she stood calmly and obediently in front of Asmodeus.

"Your name?" he asked. 

"Amanda" she replied.

"This was your name. From now on you will call yourself Asmodina. Asmodina the whore. My anal whore."

Asmodina nodded. Her eyes shone in bright red for a brief moment. The demon smiled and disappeared in thin air.

...

Amanda was very confused in the morning. She didn't sleep well. After she woke up she was quite surprised - she had slept naked without her favourite pyjamas. She got up and went to the bathroom where she found out something even more unusual. She remembered giving the blowjob of his life to her boyfriend, but there was dried up cum almost everywhere on her face. This was highly unusual. She tried to remember what happened next and why she got cum covered in her bed. Her mind was blank, only a glimpse of something dark from her nightmare showed and immediately disappeared.
