"Dear Goddess, please forgive me for my shameful sins," a girl spoke quietly into the night, "I wish to devote my life to you, but I'm afraid that I must be a healer on the battlefront rather than serve you in the church at this time. It is my calling and my place to help my friends in battle. I enjoyed the time I spent serving you and your people in the church, and I hope to one day return to that position. I swear to you though that I will always remain diligent in my faith and confess my sins to you in the hopes that you will bless me and guide me back to a position in the church."
"She prays so beautifully," Dorothea whispered. She hadn't intended to spy on the girl, but she had heard her prayer and become curious. Mercedes had always seemed so innocent and kind. No doubt she was the kindest soul in the entire monastery, but what could the girl be hiding that she was so ashamed of?
"Goddess, I confess that my weak human soul succumbs to one temptation in particular. I have tried and tried to purify my thoughts and my body, but I am unable to keep from giving in to my sexual desires."
"Oh, now this is getting interesting," Dorothea chuckled to herself.
"I know that sexual desire is only human, but I also know the consequences of giving in to human urges. I cannot allow myself to become pregnant or take a husband, for my chances of serving the church again one day would be ruined. So… I opt to satisfy myself with female companions. I know that this is not strictly forbidden by the church of Seiros, but it is frowned upon and uncommon, and that makes it difficult to find partners. I know it is not the sex itself that makes me a sinner, but it is my weakness to it. Sexual functions are only to be a means to show affection and to bear children, but I use it to quell my perverseness. It is only a function of pleasure to me, and that is why it is wrong. And if I wish to serve the church again someday, I will have to cleanse myself of all sexual activity to fully devote my life to the church."
"She seeks out women to have sex with? And only for pleasure, not love? Mercedes… I hardly knew ye," Dorothea said smugly. She too had an affection for women, though she intended for her true love to be a man. She understood the girl's plight in a way, though the difference was that Mercedes was drowning in guilt while she was not.
"Please forgive me, Goddess, and lend me the strength to overcome my weakness." With that, Mercedes rose from her kneeling position in the Cathedral and turned around. She nearly jumped out of her skin when she saw Dorothea standing in the moonlit doorway.
"Dorothea, how good to see you!" she greeted the girl nervously.
"I heard your prayer, darling Mercedes," Dorothea said.
"Oh, how embarrassing," Mercedes responded sadly, "Please do not tell anyone about it. I would be so humiliated." The girl cast her gaze on the ground and her cheeks blushed lightly. She was like a porcelain doll who's cheeks had been lightly painted with a shade of pink.
"If you ask me, there's nothing to be embarrassed about," Dorothea answered honestly.
"You don't understand. I have such perverse desires and I need to make sure I'm never found out if I want to become a nun again someday. They'll never accept an applicant who has a history of sinful actions."
"Then just do your best to never get caught."
"It's not only that. I would be lying if I said I don't intend to continue my occasional sessions with other women. I simply cannot help it. But perhaps I would feel better if I could inflict upon myself some kind of punishment for my grotesque actions."
"If that's all you want, then I know a way to do that for you."
"You do?" Mercedes asked her in surprise. Her gorgeous blue eyes glowed with intensity.
"Yes. Walk with me back to my quarters."
As they walked, Dorothea spoke about her own experiences.
"I too, have sexual urges that can only be satisfied by women," she admitted.
"Really? But you always talk about true love with a man."
"I do fully intend to marry a man who loves me with his whole being. But I also intend to marry a man with good social connections and wealth. Byleth taught me that I can strive for more than one thing in life. I've decided to apply that rule to my sex life as well. You see, when it comes to men, I long for a sexual relationship filled with commitment and deep feelings of affection. For women, not so much. When it comes to women, I crave passion and pleasure based only on lust. I would be willing to have more than one encounter with a female partner, but it would have to be under very specific terms."
"Wow, Dorothea, you really know what you want in life, don't you?"
"Yes. And I think that just because the church frowns upon fleeting sexual activity, you shouldn't give up on what you want either. You deserve to work in a position that makes you happy and have the kind of relationships that make you happy. There are other positions in the church besides being a nun, you know."
"That is true…"
"Here's my room. Come inside."
The two girls entered Dorothea's quarters. It was kept neat and tidy and smelled of flowers and spices.
"Mercedes, now that we're behind closed doors, I wish to proposition you. Both of us want to have sex with women in a way that includes no romantic feelings of any kind. We just want someone to pleasure and be pleasured by in an act of pure, carnal lust. Knowing that, I want to tell you that I'm interested in doing that with you."
"Dorothea…" Mercedes trailed off. She couldn't believe what she was hearing. It was normally so hard for her to find a sexual partner and here was one of the most attractive women in Gerreg Mach offering herself to her.
"I accept your offer, but what does that have to do with my punishing myself for my sins?"
"I will punish you. We will have a relationship in which you play a submissive role and I play a dominant role. If my intuition is correct, you get off on being subservient anyway, correct?"
Mercedes blushed just thinking about what Dorothea was saying.
"Yes, I do."
"Excellent. Tonight we will do a trial run of the suggested arrangement, and you will have a chance to break the deal if you don't like it."
"Okay," Mercedes agreed.
Dorothea walked up to Mercedes and ran her hand through the girl's magnificent mane. Prepare to be punished, my naughty girl," she said gently, "You have committed a shameful sin, and now you must repent to the Goddess."
"Forgive me, mistress," Mercedes whispered.
"Stand completely still as I undress you." Slowly, almost torturously, Dorothea undressed Mercedes piece by piece. Once she was naked before her, she ran her hands over the girl's pale body.
"You must pay for your sins, you dirty slut," Dorothea said as she squeezed the other girls pussy with her hand. Mercedes let out a whimper and bowed her head shamefully.
Dorothea led Mercedes to her bed and sat down before she dragged her across her lap. Mercedes now laid across Dorothea's clothed lap with her bare bottom raised in the air. Dorothea took a little time to inspect her new companion. She grabbed her ass cheeks and spread them apart, getting a full view of Mercedes' holes. Her skin was pale and smooth, even on her genitals. She was a soft woman with generous curves and little muscle, much like herself.
She released Mercedes' bottom and drew her hand back before bringing it down hard on the girl's right cheek. She gasped in pain but managed to keep quiet. The walls of the dorm were thick stone, but shouting or yelling would be loud enough to reach their neighbors' ears. Dorothea continued to assault the girl's bottom, making sure the land a few hits on her pussy as well. When Mercedes bottom had turned a nice shade of bright pink, she decided that the girl had been beaten enough. Tenderly, she pressed two fingers against her pussy until they slid in, causing Mercedes to moan.
"This is only the beginning of your punishment. In order to redeem yourself, you must service me any way I choose. But first, I think you need to be taught a lesson. Get on the bed on all fours. I expect you to arch your back and offer yourself to me like a good girl, understood?"
Mercedes nodded and rose to her feet before assuming the position on the bed. Dorothea rummaged around her shelves for a moment before returning. She placed a book in front of Mercedes and opened it up to a random page.
"This is one of the holy texts of Seiros. Clearly a sinner like you needs to review the teachings that will lead to a pure and blessed life. I want you to read starting here and not stop until I tell you to. I will be giving you the pleasure you desire so much, but under no circumstances are you allowed to cum, understand?"
Yes, thank you, Mistress," Mercedes said apologetically. She began reading the verses out loud as Dorothea knelt behind her. She leaned in close and gently breathed on Mercedes pussy, causing her to clench her muscles in response. She then began to lick the girl's slit gently, occasionally sticking her tongue up to flick her clit or probe into her tunnel. Mercedes managed to keep reading without missing a beat.
After some more teasing, Dorothea began to eat the girl out more aggressively. She lapped at the girl's pussy with fast hard strokes over and over. She sucked on her clit which caused her to stumble over her words and moan. Dorothea moved up to the girl's asshole and licked it, sticking her tongue inside for a moment before withdrawing it. Mercedes was really struggling now to continue reading, but she had managed to hold back her orgasm. Dorothea cruelly gave Mercedes' clit one more suck before withdrawing completely, leaving the girl in a state of incomplete torturous pleasure.
"Turn over and lay on your back." Dorothea commanded. Mercedes did as she said. While she was waiting, Dorothea removed all of her own clothing, bearing her own soft curvaceous body to her new submissive slut. She walked to the head of the bed and positioned herself so that she was straddling Mercedes' face.
"Serve me and you will be redeemed and cleansed of your sins," she told her. With that, she lowered her pussy to Mercedes' mouth, and the girl began to suck and lick with vigor. Dorothea ground her clit against Mercedes' tongue as she worked. With one hand she reached back and fingered her own asshole as Mercedes sucked on her clit hard. After several minutes of aggressive grinding, Dorothea came hard and Mercedes lapped up any juices that flowed out of her.
"Good girl," Dorothea praised her as they both panted, "I haven't forgotten about you though." She reached over into a drawer near her bed and pulled out a smooth glass dildo. She slid down Mercedes' body until she reached the girl's milky thighs. Mercedes spread them apart and offered up her pussy lustfully.
Dorothea rammed the dildo into Mercedes' pussy, causing her to moan loudly. She aggressively fucked the girl with the object and rubbed her clitoris with her thumb. Mercedes large breasts bounced up and down wildly as Dorothea slammed the object into her again and again. Mercedes lost control and her body locked into a position where her hips were raised and her back arched. An explosive orgasm washed over her body more intensely than any ever had before.
Dorothea smirked as she watched the blonde's eyes roll back into her head with pleasure. Watching someone else cum was almost as satisfying as her own orgasm.
As Mercedes' orgasm ended, her hips lowered and she panted lightly with exhaustion. Dorothea withdrew the dildo from her pussy and laid it to the side.
"Let's be honest for a moment, and then you can give me your answer," she said, "I am no authority that can wash away your sins. I spoke like that because I had a hunch that roleplay like this would get you off like nothing ever has. You can find your own answers as to what makes you actually feel better about yourself. But the benefit you do gain from this is that you have a steady source of sex, and a partner who you can trust to keep it a secret from everyone else. On top of that I can guarantee that there will be no romantic feelings between us. So if you found our little session pleasurable… I'd like us to make this a regular thing."
Mercedes gazed up at her friend with earnest eyes.
"Yes. Let's make this an official arrangement. If you can give me sex like this on a regular basis, then I'm happy to become your submissive bedmate."
Dorothea smiled and leaned down towards the girl, sealing their deal with a short kiss.
"When you need some relief, come see me again," she told her, "I'll give you a key to my room and you can let yourself in whenever you know I'm here."
"Thank you, Dorothea."
With that, Mercedes dressed herself and left the room, heading back to her own quarters for the night. Dorothea couldn't believe what luck she'd had tonight. As she wrapped her naked body in her warm blankets, she found herself looking forward to her next session with Mercedes, and all of the wonderfully naughty things she would do to that sweet, kind girl.
