Mary was a pretty girl with dark hair, brown eyes and bigger than average breasts. She wasn’t the brightest person, but she had a good heart. All through catechism, confirmation and Catholic school, Mary attended mass regularly and went to confession every week. She did her best to avoid temptation, but it wasn’t easy with the devil lurking nearby.

At the end of her junior year in high school, Mary turned eighteen. Jimmy Parker, a boy she liked from her church youth group, asked her on a date. They went to the movies. Afterward, Jimmy drove to an overlook to admire the view of the city lights. He put his arm around her and pulled her close. They kissed. 

Mary had kissed other boys, but nothing like this. His tongue slid into her mouth. He moved his hand up her waist and over her breast. She knew it was wrong to let a boy touch her like that, particularly on a first date, but Jimmy was special and his fingers felt good. Her nipples swelled under his touch. She felt a throbbing between her legs that made her light-headed. 

Mary went to confession the next day. She explained what had happened during her date with Jimmy. Father O’Brien said that it was normal for girls her age to experiment with boys as long as they didn’t go too far, and as long as she came to confession and told him about it. He made her say three "Hail Mary’s."

On their next date, Jimmy slipped his hand under her blouse and squeezed her naked breasts. His fingers rubbed the sensitive nipples. The throbbing between her legs returned, this time more powerful. Jimmy slid a hand under her skirt and rubbed the damp crotch of her panties. Mary became dizzy and disoriented. Her body jerked and twisted in a series of uncontrollable spasms. She squealed. Her panties got so wet she thought she had peed herself. 

In bed that night, Mary tried to make sense of it all. Sister Anna always said that the area between her legs was the devil’s playground. The devil must have possessed her. It would explain why her body had jerked and contorted so violently. Had she gone too far with Jimmy? She wanted to discuss it with Father O’Brien at confession, but she wouldn’t have time. She was leaving in the morning for a month-long summer program organized by the church.

Mary stayed with Paul and Penny while she attended the summer program near where they lived. Paul was her father’s roommate from college. Penny was his wife, although ten years younger. They didn’t have any children of their own and were happy to host Mary. They insisted she call them Uncle Paul and Aunt Penny even though they weren’t related.

One afternoon Mary returned to their place early. She heard strange noises coming from the house as she approached the front door. 

“Oh god… yes… right there… NNNGGGHHH…”

Alarmed at hearing Penny’s screams of agony, Mary threw open the door and ran inside. She stopped and stared in disbelief at the scene in front of her. Penny was on the couch with her legs spread wide. Paul had his head between them. It looked like he was biting her privates, but that didn’t make any sense. Why would he do such a thing?

“Uncle Paul!  What are you doing to Aunt Penny?”

Paul pulled his head from between Penny’s legs and looked up at Mary who was standing there with her mouth open. His face glistened with juices that dripped from his chin.

“Hello Mary. You’re home early. I’m sorry you had to see what I was doing to Penny. It’s normally something we do in private, but I guess you’re old enough for me to tell you. Do you know about demons, Mary, the really bad ones that get into your body if you have impure thoughts or do something inappropriate?”

Mary nodded. She knew that demons were agents of the devil. She didn’t know exactly how they worked but was quite sure that demons could possess the body when one had impure thoughts or committed sins.

“Good. Then you also know that demons need to be removed from time to time. Women purge these demons from their bodies during their monthly visit, but sometimes that is not enough and additional cleansings are necessary.”

Her mother had told her that the curse, which visited her every month, was nature’s way of cleansing her body of its demons. She had never mentioned the need for additional cleansings.

“What you saw me doing, Mary – well, I was sucking the demons from Penny’s body. It’s not something people talk about because of the very private nature of how it is done. Most people your age are not even aware of such a procedure, or if they are, have been taught that it is immoral.”

Paul was right. Mary had never heard of such a procedure. Neither Sister Anna nor her friend Kathy, who knew everything about these kinds of things, had ever mentioned it. It did seem weird that Paul had to use his mouth on Penny’s private parts to remove her demons. On the other hand, that was where she purged her demons during her monthly visit.

“How could it be immoral if it’s helping to remove a person’s demons?” Mary asked.

“It’s not Mary, but church doctrine is very conservative. The act of removing demons using one’s mouth brings pleasure to the person whose demons are being removed. The church frowns on such physical pleasure and believes that the devil can be kept at bay through sheer willpower. Most of us aren’t strong enough to resist the devil on our own. He knows that and takes advantage of the weak.”

What Paul was saying made sense. Mary had been weak when she let Jimmy touch her between the legs, but she did get a great deal of pleasure from it. The devil must have taken advantage of her weakness and possessed her. It was why her body had jerked and contorted like that girl in the movie.

“It’s not unusual for girls your age to experience an excess of demons,” Paul continued. “It can happen when impure thoughts enter the mind or when you do something inappropriate with a boy. You can tell because you get wet between the legs. It’s your body trying to expel the excess demons until your monthly visit. Perhaps you’ve experienced it yourself Mary.”

That must be why her panties were soaked when she got home from her date with Jimmy. Were the demons still inside her? She hadn’t had her period.

“You looked concerned, Mary. If you would like, Penny would be happy to examine you to determine if you have a build-up of demons?”

Mary nodded. It certainly couldn’t hurt. She was glad Penny was doing the examination. She would be embarrassed to let Paul see what she looked like down there.

“Sit down and relax,” Penny said. “This will just take a second.”

Mary sat on the couch. Penny removed her cotton panties and spread her legs apart, staring hungrily at the gash visible through a forest of dark curly hair. She spread the lips of her pussy open.

“Oh my,” Penny said. “Mary, you do have a serious demon problem. Would you like me to remove them?”

Without Father O’Brien to advise her, Mary had to trust what Paul and Penny were telling her about demons. She looked up and nodded. Penny moved her face between Mary’s legs and flicked her tongue along her slit. Mary gasped at the unexpected rush of pleasure. When Penny clamped her mouth over Mary’s swollen pussy and pushed her tongue inside, Mary felt it working right away.

“Oh yeeesss… please Aunt Penny… ooohhh…”

Mary could feel the slimy demons streaming from her body and running down between the cheeks of her bottom. Penny did something with her fingers and tongue that caused Mary’s body to twist and buck in a series of convulsions just like it had with Jimmy, only more powerful. It certainly felt like the devil was being driven from her. Demons poured out from between her legs. Penny eagerly sucked the sticky fluids into her mouth.

“Don’t you feel better?” Penny asked, lifting her face from between Mary’s legs and wiping the juices from her lips and chin.

Mary nodded. A feeling of euphoria had spread through her body. Nothing had ever felt like that, not even when Jimmy touched her there. It left Mary breathless.

“Good,” said Paul. “Now Penny is going to demonstrate how to remove demons from a man. Unlike women, men do not have a natural monthly cleansing and their demons build up more rapidly. They need to be cleansed almost every day.”

Mary had always wondered how men purged the demons from their bodies without a monthly visit. Paul unfastened his pants and pushed them down his thighs. Out popped his very erect penis. Mary’s eyes grew big. Paul wrapped his hand around it.

“A man’s demons are extracted from here. Just like with women, they accumulate in those private places that cause the most temptation.”

Mary’s head was spinning. This was too much to absorb in such a short time. She watched Penny kneel in front of him and slide her lips down his shaft. She knew from Kathy that Becky Martin had done this with several boys at school. It was called a blowjob. Kathy called her a slut, but what if Becky was removing demons? That wouldn’t be a sin, would it?

Mary watched in amazement as Penny's mouth flew up and down Paul’s cock. When Kathy had told her about Becky Martin, the idea of having a man’s penis in her mouth sounded disgusting, but watching Penny do it was anything but disgusting. Mary closed her eyes and tried to envision how it would feel to have Paul in her mouth. The throbbing between her legs returned.

“Would you like to try?” Paul asked. “It’s a valuable skill to have. Think of all the people you can help.”

Mary had so many questions, but all she could think about was the burning desire to have Paul’s penis in her mouth. She looked up and nodded.

“Good. Penny will teach you how. I do need to warn you that a man’s demons shoot out all at once. I’ll let you know when it’s about to happen.”

Mary dropped to her knees in front of Paul. Penny guided his hard cock to her lips. She opened her mouth and let it slide across her tongue. It felt so warm and full of life. Paul put his hands on her head and moved in and out. Mary wrapped her lips tightly around him, hoping she was doing it right.

“That’s good Mary. Use your tongue and suck in and out… yes… just like that… ooohhh… you’re a natural.”

Paul moved faster and faster, bumping the tip of his cock against the opening to Mary’s throat and causing her to gag. Mary did her best to keep up with him but it was difficult. Spit drooled over her lips and dripped from her chin. She felt him stiffen.

“I’m going to shoot,” Paul grunted. “Get ready.”

Mary wasn’t sure what he meant. Was there something she was supposed to do to get ready? She felt him swell inside her mouth. Paul thrust deep and grunted.

“AAARRRGGGHHH…”

A warm creamy liquid sprayed into her mouth and washed across her tongue. He continued to shoot spurt after spurt. Mary couldn’t believe there were so many demons. When he finished, he pulled out. She wasn’t sure what to do. She could feel some drooling over her lower lip. She looked up at Paul for guidance.

“You can swallow it, Mary. The stomach acids will kill the demons. You did an excellent job. I feel so much better. Thank you.”

Mary closed her eyes and took two big gulps. It wasn’t bad. She smiled up at him, glad to have helped, but she was confused about one thing.

“Uncle Paul, I have a question. What’s the difference between the demons that shoot out of your penis and the stuff that makes babies? Don’t they all come from the same place?”

“Excellent question, Mary. The Devil is very clever and hides his demons in the same stuff that makes babies. It’s why they have to be extracted using the mouth. Sexual intercourse is another way to remove demons from men and women at the same time, but you risk the possibility of getting pregnant.”

What Paul said made sense to Mary, but she had another concern. More demons had accumulated in her own body while she was removing Paul’s. She could feel them oozing out from between her legs. Penny offered to help, explaining that often happens when removing a man’s demons. Mary was out of breath and barely conscious when Penny finished removing her demons for a second time.

The next morning Penny had already gone to work when Mary arrived for breakfast. Paul was sitting at the table with his hands on his head.

“Hi Uncle Paul. Are you feeling okay?”

“Hi Mary. I’m having a bit of a problem. I had some very sinful dreams last night and I’m full of demons. I hate to ask you to do this, but could you possibly help me out? If Penny were here I’d ask her.”

“Of course, Uncle Paul. I’d be happy to.”

Mary felt her nipples swell. The familiar throbbing between her legs returned. She couldn’t wait to get his penis into her mouth. Paul pushed his shorts and briefs down to his knees. His hard shaft poked up from his lap.

“Do you remember how to do it?”

She did. This time, Paul taught her how to put his cock down her throat, explaining that this helped force out the really stubborn demons. It worked. His demons came shooting out in a series of powerful spurts. Mary swallowed them all. Now her panties were soaked. She needed a cleansing, but Penny wasn’t around. Paul noticed the worried look on her face.

“Mary, do you need another cleansing? I would be happy to help.”

Mary was desperate and agreed. Paul turned out to be an excellent demon remover. The devil was so entrenched that her body twisted and contorted twice before all the demons were expelled.

Over the next two weeks, Mary and Penny took turns removing Paul’s demons, sometimes sharing the duty. Penny taught her how to use her tongue to clean the demons from a woman and even how they could remove demons from each other at the same time. She also showed Mary how to remove demons at night by using her fingers when she was alone. Mary had been taught by Sister Anna that masturbation was a sin, but it had to be better than letting the demons fester in her body.

When it was time to leave, Paul drove Mary to the bus station and asked her to remove his demons one last time in the front seat of the car. She gladly obliged. Once she swallowed his stuff, Paul used his fingers to help Mary purge her demons. He walked her into the bus station and made sure she had a ticket, then said goodbye and went back to the car.
