With a shock of startled fear, she opened her big blue eyes suddenly, and through her lust-clouded vision found herself looking into the smoldering eyes of her own brother.

"J-Jarvis!" she squeaked breathlessly, too shocked to make any attempt to cover herself.

Her lust-heated eyes drank in the sight of his heavily muscled, tanned torso and the conspicuous bulge in his trousers. She also saw the answering glimmer of lascivious excitement in his troubled eyes.

Quivering with passive excitement, her huge baby blue eyes fixed a pleading look on her big brother's face.

Jarvis stared at her, dumbfounded, and then took a deep breath, stepping quickly into the room and closing the door behind him. He turned the latch, and then walked slowly to the side of his sister's bed.

"Melanie, honey," he said huskily, sitting down beside her, "You've gone and blossomed into a young woman without my even noticing! Shit, honey, I must have been blind."

His burning green eyes raked over her trembling, translucent flesh, and he gently reached out and brushed his fingers over one of her pillowy bosoms, drawing it down and plucking at the ripe red nipple.

"J-Jarvis," Melanie whispered feebly, "D-Do you think we should?"

"I don't know," he replied hoarsely, looking at her, "Do you want to, honey?"

Melanie gave a ragged sigh and said softly in a quavering voice, "Yes! I-I really do!"

Jarvis nodded, his head reeling with excitement, unable to resist the temptation of his sister's luscious, beckoning body, and yet, unable to shake the nagging voice which told them that what he was contemplating doing was wrong. His heart pounded violently in his chest, and his loins seemed to be on fire. His rigid pecker stretched painfully against the tight material of his trouser leg.

He licked his lips, running his hand slowly over his sister's body, reveling in the sensation of her delicate, satiny flesh against the coarse skin of his palm.
