Redeem her

The rules of this esoteric ritual still evades you, but you still manage to recognize a big red flag when you see one. Exhaustion? Hospitalization? Your dick is still sore from earlier escapades, despite standing stiff, throbbing with artificial eagerness. Tempting as Molly is, no thanks.

"Redemption." You groan. Once more committing blindly and raising excited gasps from the spectators.

"Nooooooo!" Molly whines and looks around with a pleading expression but finding little mercy in their eyes - least of all from the Cult Matron who nods decisively.
"Chastity it is!"

Molly pouts ever so prettily and leans once against your dick. You can feel your tip slide past her inviting pussy, feel the nub of her clit as your hardness brushes against it and her eyes widen in pleasure. You can clearly see her divided feelings from her face and for one moment you're certain she's going to throw ceremony to the wind and plunge herself fully down on your length. But she manages to control herself and reluctantly pulls herself off the alter completely.
Molly hesitates for a moment, her eyes seeking someone you can't see in the crowd. Whatever hint Molly is looking for, she seems to have received because she nods.

Once more her lithe form climbs atop the alter above her, this time she is approaching from above your head. Her cute face pass by, then her perky breasts - nipples rock hard - her flat stomach and slender legs, until she's standing over your body in a 69 position. You're treated to the clearest view to shaved pussy. Her lower lips are a darker brown and her excitement is practically dripping from her.

"I really wanted to fuck you.. So. Much!" she sighs and you feel her hot breath tease your hard shaft. Her mouth can't be more than an inch from your cock. The thought alone sends a jolt through you.

"Oh you want me to suck your prick! Goddess I would've sucked it for days. I can take it all the way in, you know. No gag reflex." Her words are teasing, but you don't seem to be the only one they arouse. Her hand has snaked between her legs and started to rub her clit right in front of your face.

"I can feel you sighing.." She moans, her fingertips drawing circles around her sensitive spot, ".. You want this too! Want me to sit down on your face, drown you in my pussy! And then I'd start work on your dick. Hands first, real gentle-like. Boys always like it better if you tease a bit first, even if they won't admit it. You all like being denied, I don't!"

Her fingers move down and with a lurid squelch she dips them into her wet slit. Her words come out more staccato as she really starts going to town fingering herself.
"Fuuuuck.. I'd let you play with my pussy all you'd like, but once I got serious you'd be done. I have this humming trick that drives cocks wild. I love it when you sixtynine a dude and just feel his concentration completely slip. There's someone so hot about shutting off his brain and grinding on his panting tongue. Wouldn't you have liked that.. Aahh.. Fuck.. Wouldn't you? Just turned in-oohhh-to a braindead... pleasure-toy.."

You notice that Mollys legs are tensing, her rhythm starts to turn uneven and you can tell she's close. Her moans fill the clearing, but just as she looks about to cum she stops completely.

Silence. Molly is breathing heavily, what you can see of her face past her body, she's grimacing as she rides out the edge. A minute pass.

You hear the Mother Superior utter a single word: "Again."

Molly's hand finds it way back down to her clit and she starts teasing herself once more. Her slight fingers gently stroking along her pussy lips before returning to her nub.
"That would only be the beginning though. The main show.. Oh.. I'd start letting me fuck you however you'd like. My pussy, my ass, my face.." She impatiently thrusts her fingers into her wet hole. Quickly setting a fast pace. "I love doggy style though, so we'd do that a lot. Getting rammed from behind really does it for me." She is pistoning her fingers in and out faster and faster.
Each sigh, each moan, each single dirty word sends a teasing gust past your cock. But that's all the attention you get. "And.. ahh.. when you grew.. tired and.. and.. your legs gave out, I'd start riding you. Cowgirl, reverse cowgirl, amazon. We'd get around to the whole kama sutra, believe me. In... Nnngh.. the end all the boys end on their back with me abo----OOOOOHHH..." the second orgasm comes upon her quickly and just as abruptly Molly stops masturbating. Though you can tell it pains her to do so.

Her legs are quivering, the arm supporting her buckles and her cheek comes to rest by your hip, where she lies for a moment - face down, ass up - while the edge passes. Then a merciless voice rings out.

"Again."

The third time Molly doesn't bother with fantasizing about all the terrible things she would do to you. She keeps her face lying on your pelvis, right next to your cock and balls. With both hands she starts again. 3 fingers pounding her own pussy, 3 fingers polishing her pearl.
There is no refinement left, just sloppy desperation. Her moans have definitely taken a more whining quality.
You feel her pussy juice spray on your face, some of it landing in your mouth. You wish your hands weren't tied so you could similarly pleasure yourself, but you're left watching as this eager teens edges herself insane. You're fairly certain you feel her drool running into your pubes, but she seems completely gone. Finally she tenses up and this time she starts shaking for a solid 30 seconds, which only intensifies more and more and more until she stops for a final time..

Her hands falls limply on your chest and for a moment she just lies there. Then you hear grind her teeth together and with a grunt she pulls herself up, turnings around and stands on quivering knees above you - her expression awaiting.

"Sister Molly has controlled her urges. No once. Not twice but three times. What is your judgement?" The Mother Superior's voice is definitely more tender as she leaves Molly's fate in your hands once more.
