You know damn well what it is.

Once his office door was locked, sister Monica looked at Aktheus lasciviously. He smiled, a bit nervous. If she had planned what he thought she had planned, this was his day. If not, well...

Sister Monica slipped off the hood on her habit, letting her long blond hair fall to her waist. She smiled, and Aktheus did too. Now he was sure that her plan was one he was more then willing to follow. He pulled his robe over his head and tossed it over the back of a chair. Monica raised an eyebrow appreciatively and reached behind herself to undo her uniform. Button after button popped out of place, slowly allowing the fabric to loosen. Finally, it fell to the floor. Aktheus almost fainted seeing her naked form this close for the first time. Perky c-cups with light pink nipples, which right now stood hard and erect. Allowing his gaze to wander down, he noticed her loin covering, small cloth shorts, were still in place.

"You want these off? I want you to take them off of me. Will you, please?"

He couldn't have said no if he'd wanted to, and there was nothing he wanted to do less. He strolled over, trying to look smooth, and slipped them down her smooth, shapely legs. She giggled as he looked up into her pussy from one knee on the floor.

"Am I dripping on you, father?"

He shook his head, which sister Monica acknowledged with a look of mock-disappointment. Aktheus smiled and gave her pussy a few long, slow licks. She moaned, and now she was dripping on him.

Aktheus had waited years for this moment, and he was through putting it off. He rose to his feet, put one of sister Monica's legs around his waist, and slid his hard cock into her. She gasped at the sudden penetration, but almost immediately began moaning in pleasure. And so did Aktheus. Her pussy, though not quite virgin, was almost air-tight, and still sopping wet. He guessed she had only been with one other man, or had broken her hymen some other way. But that quickly fell to the back of his mind, pushed aside by the present reality. The fate of her cherry notwithstanding, the pussy that had housed it felt beyond incredible. He pumped in and out, lightly at first, but harder as he went on. Soon, he was pounding her wet twat with a vengeance, and she responded by pushing her hips forward and down in a circular motion. She pressed her face into his shoulder and began gasping dirty things into it.

"Yes....fuck me, father, fuck me hard...yes...yes, you feel so damn good in my tight cunt, i can't stand it....fuck me hard until i'm loose..."

The encouragement made Aktheus lift the other leg and put it around his waist as well. Sister Monica wrapped it around him tight, and threw her head back in ecstasy. She shrieked and sighed as he continued thrusting into her. Her pussy soon pulsed, getting tighter and wetter, gripping and releasing Aktheus. He too was nearing orgasm.

He wanted to cum in her, to fill sister Monica with his fluid love. But at the same time, children were not exactly what he wanted out of this newfound mutual fondness.
