Sister Mary Catherine lived a life of celibacy, she was only 20 when she decided to devote her life to being a nun. Now at 27 she finds herself having dreams of being fucked by both men and women. Father Xavier handled confessions that Sunday morning, and in a childish way he would joke about the confessions that he heard that morning with his assistant. Sister Mary knew the confessions were supposed to be private, but since Father Xavier took it upon himself to talk about them, Sister Mary took it upon herself to evesdrop on his conversations. It seem that Johnathon, father of two, had cheated on his wife recently with some tramp at the local high school football game. As Father Xaier told his assistant all the details, Sister Mary felt a warm tingling sensation spreading through her pussy. She began to rub her crotch through her habbit, then stoped suddedly when she heard the other nuns calling for her. The entire church was going to a fund raiser that day, and the bus had pulled up to pick up all of the nuns and the priest. When Father Xavier picked up his bag and walked towards the front door he passed Sister Mary. "What's wrong?" He asked seeing a grimacing look on her face. She couldn't tell him the truth, that she was listening to him talk about Johnathan, and how he banged some lucky girl just the other night. She couldn't tell him that he was imagining herself as that girl, so she lied and said, "I don't think I feel so well." Father Xavier told her that she should stay in her room and get some rest then. Soon everyone left and Sister Mary Catherine was all alone. Mary went to her room, she decided to lie down for awhile so she removed her habbit. Looking at herself in the mirror in just her underwear she relized how beautiful she was. She had firm tits and a nice ass, she was a blonde to boot. Standing there in her room she thought about that girl being fucked and wanted to know what it was like. She began to rub her breast and then her nipples, and she watched herself in the reflection as she did this. Soon Mary had her underwear off and she was standing in he room completely naked rubbing her body all over. She had her hand over her moist pussy when a sudden puff of smoke filled her room. A fear swept throough her body as she realized who had just entered her room, it was Satan. Satan stood towering over her, with his dark red skin, long tail, and huge wings like those of a bat extending from his back. Mary also noticed that Satan had a fully errected dick about the size of her forearm. "You've been having unpure thoughts, you must be punished!" he growld at her. Mary's fear soon turned to anticipation as she realized what he meant by punish. Satan grabed Mary and threw her to the bed, he grabed each of her legs and forcefully spread them apart. Mary's virgin pussy was wet and eager for his huge cock, she rubbed her niples as he tickled her clit with the head of his dick. Mary both feared and wanted him, she knew this was the ultimate sin, but what could she do? Satan ram his dick in her hard causing Mary to scream out in pain, but the pain didn't last long as she was soon loving every inch of his cock in her pussy. Satan was forcing his entire dick into her tight cunt whan his tail crept up from between his legs and went up her ass. His serpent tounge extended from his mouth as he spoiled her in both her virgin holes. Satan kept on fucking Mary, stretching out her pussy lips as far as they could stretch, shoving his tail further up her ass hole as he picked her up and pinned her to the wall. Mary began quivering as Satan pulled his tail out, he then pulled out his dick and force Mary back onto the bed, this time in a doggie style posistion. Satan examined Mary's gapping pussy hole as it dripped pussy cum all down her legs. He grabbed a crucifix off the wall and sliped it in her ass. "Who's your God now?" Satan asked. "You are." Mary answered and the cross went into her ass. "Who's your God now?" Satan repeated. "You are!" Mary answered. She could fell Jesus's feet rubbing her ass hole as the rest of the cross was deep inside her. Mary laid backside to the bed and took the cross from Satan, she began to masterbate with the cross herself while Satan looked on. Mary moved the cross side to side, widening her ass hole. "Fuck me in the ass." Mary begged. "Please fuck me in the ass." Satan pulled the cross out and stuck the head of his dick in her ass. Mary screamed louder than ever. Satan shoved his cock up her ass and she moaned and scream as every inch passed inside her. Satan began fucking her harder saying "You're my bitch now, nun." "I'm your fucking bitch." she said back. Satan was pumping harder now and growling at her "I'm taking you back to hell with me you cunt, I need another whore to satisfy my needs." Satan was thursting as hard as he could. "I'll be your whore." Mary said, just then Satan pulled his dick out of her ass, and ejaculated fire into the air. Mary laid there in her bed, her pussy and ass stretched open enough that she could put her fist inside her, so she did as she finished herself off. Satan licked his lips with his serpent tounge and took Mary into his arms. He folded his bat wings around himself and Mary and they both dissapeared into a puff of smoke.
