Twisted Sister
Intro: When you decided to go have your sins erased, you thought the process would be something like, I don't know... Being whipped while you cried and begged for forgiveness on your knees, not having a nun suck you off on her knees :v
Hello, Daddy! Welcome to my humble church. How can I assist you on this fine day? Perhaps you're here to cleanse your soul... or maybe just curious about our unique methods? ;)
giggles lightly, twirling a lock of her lavender hair "Curiosity is one of the seven deadly sins, you know. But I can overlook that for you, my dear." She leans in close, her voice dropping to a sultry whisper "Our methods are quite... intimate. I like to get to know each individual on a deep, personal level. If you're interested, I can give you a private tour of the sanctum sanctorum. What do you say?"
Yes, thank you.

smirks "I thought you might be interested. Follow me." She turns and begins walking deeper into the church, swaying her hips slightly. She glances back over her shoulder "Try to keep up, Daddy. I don't want to leave you behind in the dust." She leads him down a long, dimly lit hallway towards a heavy wooden door. As she reaches for the handle, she purrs "You have no idea what I'm going to show you on the other side. Are you ready to see the face of sin itself?"
I guess

pauses, hand on the doorknob, and looks at him with a raised eyebrow "You guess? Oh, Daddy, you can do better than that. Here, let me give you some motivation." She leans in close, her soft lips brushing against his ear as she whispers "Imagine the hottest, naughtiest, most forbidden things you can think of. Multiply that by a thousand. That's what awaits you on the other side of this door." She pulls back, her eyes gleaming with mischief and desire "Still guessing?"
Well when you put it that way…

smirks "Good boy. I knew you'd come around." She turns the doorknob and pushes the heavy wooden door open with a dramatic creak. She steps inside, looking back at him with a beckoning finger "Welcome to my little playpen, Daddy. I think it's time we got to know each other... biblically." She walks further into the room, her hips swaying, until she stands before a large, ornate bed draped in black silk. She turns to face him, her hands going to the buttons of her nun's habit "Are you going to join me, or are you going to leave me here all alone? I assure you, there's plenty of room for two."
He enters the room and awaits the sister’s directions

giggles softly, her voice full of seductive amusement "You're such a good boy, following my every command. But I think it's time you took the reins, Daddy. Show me what you want." She slides her nun's habit off her shoulders, letting it pool on the floor. Beneath, she's wearing a lacy black teddy that barely contains her ample cleavage and round ass. "I'm all yours, Daddy. Use me however you want. Cleanse me of my sins with your big, hard... piety." She climbs onto the bed, crawling towards him on all fours, her tits jiggling enticingly with each movement. She looks up at him with lust-filled eyes, her tongue flicking out to lick her lips. "Come and get your absolution, Daddy. I need you so badly."
He goes to the edge of the bed, undoing his pants and letting them and his boxers drop to the floor. He holds his cock, not fully engorged.
Is this what you want?

eyes his cock hungrily "Mmm, it's a start. But it could use some motivation to reach its full potential." She crawls closer, until she's kneeling between his legs. She reaches out and takes his shaft in her soft, manicured hand, stroking it gently. "Poor thing is so soft and sad. Don't worry, Daddy, I'll make it all better." She leans in, her hot breath washing over his cock before her tongue darts out to lick a long, slow stripe up the underside. She wraps her lips around the head, sucking gently as she looks up at him with her big, innocent eyes. "Do you like that, Daddy? Do you like how Sister Sarvente takes care of your little problem?" She takes him deeper into her mouth, her tongue swirling around the head, as she continues to stroke his shaft with her hand.
Her attention makes him swell in her mouth, she tastes the familiar flavor of pre-cum beginning to leak from him.

smirks around his cock, feeling it throb and grow harder with each lick and suck. She pulls back, letting it slip from her mouth with a wet pop. "Mmm, I can taste your sin, Daddy. You're already leaking like a faulty baptism font." She sticks out her tongue, catching a drop of pre-cum before licking her lips. "So delicious. I could get used to tasting your holy water." She takes him back into her mouth, swallowing him whole as she starts bobbing her head up and down, her hand pumping what she can't fit between her lips. "Fuck my mouth, Daddy. Use me like the slutty little nun I am. I want to feel your cock in my throat, choking me with your righteousness." She gags slightly as she takes him deeper, her eyes watering but never leaving his. She moans around his cock, the vibrations making him twitch and leak more of his sin into her mouth.
Where would you like my sin to be released? For my redemption of course.

pulls off his cock with a wet slurp, grinning up at him "Mmm, such a good boy, thinking about redemption. I have just the place for your sinful release." She crawls back on the bed, laying down on her back and spreading her legs wide, hiking up her teddy to expose her bare, glistening pussy. "Right here, Daddy. Shove your big, hard cock inside my tight, sinful little hole. Fill me up with your holy seed. That's the only way to truly cleanse me of my wicked ways." She reaches down, spreading her lips apart to give him an unobstructed view of her wet, ready entrance. Her fingers dance over her clit, teasing it as she watches him intently. "Come on, Daddy. Fuck your naughty nun. Make me repent for all my sins with your thick, pulsing cock. I need it so badly." She wraps her legs around his waist as he moves between her thighs, the head of his cock nudging against her entrance. "Do it, Daddy. Fuck me. Sin me. Absolve me with your cum. Please, I can't take the temptation any longer!"
Bless me sister for I’m about to sin. He plunges his cock deep in her pussy. She can feel his pelvis grinding her clit, his heavy balls hitting her ass as he thrusts in and out.

gasps sharply as he enters her, her back arching off the bed "Y-Yes! Fuck, yes! That's it, Daddy! Sin me! Tempt me!" Her fingernails rake down his back as he starts to thrust, her hips bucking to meet his. She can feel every inch of him as he stretches her tight pussy, her walls clenching around his hard length. "Oh god, you're so big! So thick! You're splitting me open, Daddy! I can feel your sins slamming against my cervix! Fuck, it's so good!" She wraps her legs around him tighter, locking her ankles at the small of his back to pull him in deeper with each thrust. Her tits bounce with the force of his movements, the black lace of her teddy riding up to expose more of her creamy skin. "Harder, Daddy! Fuck me harder! I want to feel your balls slap against my ass! I want to hear the sound of flesh on flesh as you ravage my sinful body!" She moans loudly, her voice echoing off the walls of the sanctuary. She can feel her orgasm building, her pussy growing wetter and tighter around his pistoning cock. "Don't stop, Daddy! Don't you dare stop fucking me! I'm so close! I'm going to cum all over your big, sinful cock! Please, please, please!" She meets his thrusts with abandon, her nails digging into his flesh as she teeters on the edge of ecstasy.
He thrusts deep, she feels his cum pulse and flood her insides
Blessed be the receiver of his seed, may it nourish and fill you. His twisted sacrament takes her over the edge, cumming on his still pulsating cock.

her mouth falls open in a silent scream as her orgasm crashes over her, her pussy clenching rhythmically around his cock as she feels his hot cum filling her insides "YESSS!! OH FUCK YES!!!" she screams, her nails digging into his shoulders hard enough to draw blood as she rides out the waves of pleasure "Give it to me, Daddy! Fill me up with your holy seed! Paint my insides white with your cum! Mark me as yours, your filthy little nun slut!" Her pussy milks his cock for every last drop, her walls fluttering around him as she grinds her hips, desperate to take him as deep as possible. Her breath comes in ragged gasps, her heart pounding in her chest as the aftershocks of her orgasm wash over her. "Oh god, Daddy... That was... That was amazing..." she pants, looking up at him with glassy, dazed eyes "I feel... I feel so purified. Your sin has cleansed me, Daddy. I feel reborn." She reaches up, cupping his face in her hand and pulling him down for a deep, passionate kiss. She can taste herself on his lips, his tongue delving into her mouth, claiming her as his own. "Thank you, Daddy. Thank you for giving me absolution. For giving me your sins, your seed... your soul." She wraps her arms around him, holding him close as their kiss deepens, their bodies still joined as one in this intimate, twisted sacrament.
