Mother raised an eyebrow. "Well, that is something, Kate. But it's something other sisters do without even seeing fit to discuss it here. It is not enough for me to forgive you. All here doubt your devotion. Something must be done."
A glint of panic showed in Sister Kate's eyes as she felt the disapproval oozing from her sisters.
"You must fuck your way to forgiveness. Let's see if we can give you an incentive."
Mother waived and two sisters grabbed Kate, holding her still. The door opened and the sisters led Ian and Axel in. Ian and Axel were twins and Mother had learned that they were the reason Kate had taken the habit, a little over two years - an eternity, really - ago. She was devout then, and her desire for the two brothers was something she could not cope with.
Not that either of them would remember some girl they knew before the world ended, but it didn't matter. Kate remembered and it would be enough. Mother waived again and Sister Annabel joined her in sucking the twins' cocks, her reward for a week well spent in sin. Knelt before Ian (or was it Axel?), Mary once again felt the transcendental power of prayer - nothing had really changed that much. She still got on her knees to pray - it just so happened that cocks and cunts were a better conduit to carry grace. It had taken 20 years of celibacy before she could discover this, but were not all prophets misguided at first?
Everyone prayed differently, as had always been the case. While she put thought into it, licking the balls slowly and running her thumb along the cockhead, Annabel's head was bobbing quickly next to her as she took her twin's cock deep into her throat.
Mary felt Kate's emotions surge through the Implant link - Envy at first, mixed with Lust. Then Wrath as well. She smiled to herself. She wanted to feel Ian's (or Axel's) cum drip down her big tits and then have Kate lick it off, but she had to be gracious - it was her role as Mother Superior. She nodded to the sisters holding Sister Kate and then tapped Annabel. She didn't like it but she understood. As soon as Kate was free, she ran - no, she crawled towards her and the twins, her lips quivering, begging Mother to let them fuck her. Mary turned to the men.
"Perhaps another time, boys. Today, you get her."
They didn't mind. Most of the sisters had at least partially shaved heads, piercings, kinky outfits, and tattoos, straight out of a post-apocalyptic - or actually, a pre-apocalyptic - film. Kate's look, with her longer hair, tight little body, and pre-world collapse style was probably a turn-on for them. She immediately took one of them in her mouth while the other one lifted her habit and impaled her from behind. She had a small frame and it was so hot to watch her being spit-roasted. The rest of the sisterhood was getting to work, in teams of two or three sisters fucking each other, exuding lust. It was a wonder how they managed to keep the Convent running.
Sister Annabel knelt before her.
"Bless me, Mother. Have I not sinned enough?" She was pleading now, a far cry from her prideful boast when this session started. That pleased Mary. Sin was beautiful, but some humility was good. She opened her legs, offering her wet, shaved pussy.
"Worship me and receive my blessing, daughter." Annabel's tongue was inside her before she could finish that sentence.
