She wants you to eat her out

Siara lets go of your dick, pulls her hand from her panties and gets up from her chair. She then picks up her holy book from the table, dirtying its pages with her fingers still glistening from her pussy juices and shoves the book aside. After making room on the table she sits on it with her legs slightly apart. Then Siara looks at you and says, “I would love it if you could taste my womanhood.”
You stand in front of the abbess and put your hands on her hips. You take hold of her wet white panties and tug at them. Siara shifts her hips to makes it easy for you to pull them off. When you do the scent of pussy invades your nostrils. Damn, this virgin is drenched. You pull her panties all the way off and then throw the soaked undergarment behind you. Siara then spreads her legs wide and makes certain to sit on the table’s edge for you. You then kneel in front of her, stick out your tongue and teasingly lick her slippery slit. When Siara experiences the first tongue on her pussy, she whimpers.

You perform this motion over and over again. Tasting her pussy while filling her with pleasure. When you feel she is ready, you bring your hands to her groin and pull her labia wide apart. With her pussy now even more exposed you slide your tongue inside her vagina. Your tongue is not as long as that of a snake demon but it doesn’t need to be. As soon as you enter her like that, Siara squeals and pulls her hips back a bit. But after the initial surprise, she pushes her hips forward again and lets your tongue explore her. As you lick her vagina, your tongue comes into contact with her maidenhood. You lick away at her virginity. Happy that it is still there for you need it sacrifice it for your spell on her to work. You then bring your tongue to her clitoris and start pressing it against her pleasure bean.
“Ooh! Oohohohoh, John. Your tongue. Ooohh my god.” Siara moans loudly.
“Is it to your liking?” You ask between licks.
“Yes!” Siara quickly replies. “This feels so much better than I ever thought it could be. Oooh, your tongue is everything I wished it to be.”
You make a mental note to thank Talith after this. It was because of her teaching that you became such a good pussy licker.
“I know of something that feels even better.” You say. “Want to try that out too?”
“No penetration.” Siara quickly says between her heavy breathing.
So even though much of her chastity is in tatters, she still is holding on to that last line of defense.
“Don’t worry.” You say. “I wasn’t going to suggest that.”

You stand up and look at Siara on the table. Some of her black hair, which has always been neatly tucked inside her veil, has some strands escaping from it. An interesting similarity to her lust trying to break free from the shackles of her religious upbringing. Behind her glasses, you can see her eyes staring lustfully toward you. You then put your hands on both her ample breasts and kiss the horny nun her full on the lips. She replies by opening her mouth and sliding her tongue past your lips. As she licks at your tongue and tastes her own pussy, you push her backward until she lies with her back is on the table. Then you push your hips toward hers and press your shaft against her slit. Siara seems to panic and tries to push you off her.
But you break the kiss and tell her, “Don’t worry, I’m not gona put it in.”
Then you slide your shaft up her slit once, pressing it against her clit as it moves. This draws another moan from Siara.
“See, they’re just touching.” You tell her.
“Alright. That’s fine then.” Siara says with haggard breath. “Please, do it again.”
You slide your shaft down her slit and then push it back up again. Over and over, you crush Siara’s clit with your hard shaft. Getting the virgin abbess to moan. In the meantime, you start gathering demonic energy in your penis. When you take this nun’s virginity you want to be ready to immediately corrupt her.
“Have you ever felt this much pleasure before?” You ask.
“N-no.” Siara moans. “This is … so much better … than masturbating.”

You can tell that she is close to orgasm. And honestly, you’re not too far off any more yourself. So, you grab your dick and pull it down until the head is right in front of her vagina. Then you rub it in circles around her virgin entrance.
As you tease her like this you bring your head close to her ear and whisper, “this far and no further, right?”
