"Oh, sweet Jesus!" gasped Sister Maria.

The blonde nun was lying naked on her bed, with her knees drawn up and her legs spread wide. She was thrusting against the right arm of Sister Pamela, who was kneeling at the foot of the bed. Her fist and a sizeable portion of her forearm were buried in Sister Maria's stretched cunt. However, the twenty-two year old nun seemed intent on taking even deeper penetration.

Sister Gabrielle stood by the side of the bed, spitting on Sister Maria's large, heaving breasts and enthusiastically flogging them with a thick, brown leather tawse. The plump, forty year old nun was wearing her veil and ankle length black skirt. Only her upper body was bare.

"Bad, bad girl," she hissed, laying another resounding lash across the naked nun's already scorched and aching breasts.

Sister Pamela watched in awe as her friend pushed forward and her slick slash swallowed a further two inches of her arm. The pair was around the same age and had taken Holy Orders together. But blue-eyed, angelic Sister Maria was by far the most sexually adventurous of the pair. In fact, she was probably the most sexually voracious slut in the entire convent.

Her cries grew more breathless and her thrashing more feverish as her excitement increased. Sister Gabrielle's thrashing of her breasts also increased in vigour. Unlike most of her fellow nuns, the raven-haired sister had little taste for conventional sapphic pleasures. However, she did enjoy inflicting pain and degradation and could wield a whip or cane with a ferocity unmatched even by the Mother Superior. Watching a beautiful creature like Sister Maria wallowing in depravity caused her fat nipples to throb like a pair of small brown cocks and stoked a pleasant fire between her thighs. She would reach the peak of pleasure alone and in her own special way.

Sister Gabrielle rolled a large ball of saliva around in her mouth, then leaned over and discharged it over Sister Maria's face. At the same time, she cupped her breasts with both hands and dug her fingernails into the soft, warm globes. The blonde nun tossed her head from side to side and whimpered deliriously. Her arms strained against the thick rope that bound her wrists to the head of the bed.

Sister Pamela slowly withdrew her arm. Her fist emerged with a soft, squishy sound. She was soaked in the juices of the other nun. Sister Maria's gaping cunt was foaming with her own honey and the dark blonde curls around her slash were also glistening with love dew.

"We should leave her tied up here until Father Quinn arrives," said Sister Gabrielle.

"He's coming today?" cried Sister Pamela.

"Have you forgotten it's the last Friday of the month?" replied the older nun.

All those in the convent knew what this meant. Father Quinn would be arriving to hear their confessions and administer his own perverse form of penance, with the help of Mother Superior. Sister Gabrielle hoped she too would be required to assist. She would enjoy cracking the cane across the backsides of a few of these blasphemous bitches.

"We can't have Father Quinn seeing her like this," Sister Pamela protested. "Who knows what he might do to her?"

Sister Gabrielle certainly didn't know. But she liked to entertain a few dark possibilities.
