This is (kind of) a fanfiction involving the characters in Matthew Lewis' novel "The Monk". Ambrosio is a monk who is seduced by Matilda into carnal pleasure and other crimes.
---------------------------------------
Out of the darkness tolled the bell thrice. Ambrosio started from his sleep and opened his eyes at the stone wall before him. Behind him, Matilda slept lightly and was roused only by Ambrosio's quitting of the bed.
He rubbed his forehead, pulling on his trousers quickly. Matilda's round, voluptuous form sat up on the mattress. She wiped the sleep from her eyes.
"Where are you going, Ambrosio?" Though modesty wasn't needed between them, she pulled the linens around her chilling breasts.
"The bell has just tolled three." He took care not to sound so, but Matilda knew he was disgusted with her.
"Cannot you stay longer?" He looked upon her naked body, stretched out in wanton invitation. Her full coral lips begged for his kiss. The moonlight crept over the windowsill, illuminating the tiny cell, gracing her cascading blond curls with a golden halo. Her creamy skin resembled polished white marble and she posed in the perfect attitude so that his mind might paint the moment as a memory. He furled his brows, dead-set on refusing her advances.
"Will you not come to bed, my perfect love?" She narrowed her green eyes, the sparkle within them entirely lascivious. She patted the bed beside her.
"I haven't the time," he argued. "I must return to my own cell. Matins will begin soon."
"You know they will not begin for at least an hour or two," she said, finding instant error in his design to leave her. She understood in the depths of her heart, why he would not rejoin her.
"Matilda..." he had turned away from her, trying to summon the words to tell her he no longer wanted to sleep with her... that he now wanted someone else. However, no sooner had he begun to express his feelings than was he put to silence by two creamy arms wrapping around his trunk from behind. His chest was still bare and Matilda took full advantage of his nakedness. The expanse of his tight muscles, carpeted with thick black hair, rose and fell beneath the expert motion of her fingertips.
"My love, Ambrosio," she addressed him. Her voice was deep and rich like melted chocolate. It dripped in his ears as she commenced seducing him. "My body is afire," she whispered. Her fingernails grazed his nipples and trailed lightly to the waist of his pantaloons. She pressed a kiss to his shoulder and it was as an endorsement of a spell. "I've ne'er desired you more than I do now." She pressed her fingers under the band of his trousers. He felt the cloth grow tight around his groin. "How you possess me," she whispered in his ear. "The embers in my soul are igniting, my Ambrosio." He felt her eyelashes flutter on his shoulder-blade as she dipped her small nose against his spine.
She gripped his manhood tightly in her small hands. "My Ambrosio," she cooed as she stroked him into full rigidity. The deliciousness of her actions kept him from moving. In hushed whispers, she promised excellent release, turning him around to face her.
