A Short Fall Down A Slippery Slope

Gerald gaped at his sister, his eyes unable to move from her gently rising bosom. He licked his lips, mustering control over the sudden rush of testosterone and lust. She’s my sister, he argued with himself vehemently. I couldn’t possibly…

She’s offering herself up, man, the voice in his head countered. She won’t care. Hell, she’d love every minute of it! Be a man. Take her!

“Well?” Katrina asked, eyeing her brother hopefully.

“Um,” Gerald struggled. “They’re, um, uh…”

“Is it my bra?” she gasped. “It’s in the way, isn’t it? Here.” The redhead rolled the cups down off her breasts causing a sharp intake of breath from Gerald as he gazed upon her bare flesh and stiff nipples. “Is that better?”

“Yes,” he said sharply, losing his inner battle. “Yes, it, it’s better, but…”

“But what?” Katrina asked.

“But breasts don’t tell the whole story,” Gerald suddenly grinned. Please, trust me, sis.

“They don’t?” she pouted. “C’mon, tell me what I need to do. Please?” She batted her eyelashes at him.

“What you need to do,” her brother said, grasping her shoulders and pulling her close. “Is,” he ran his hands down her back, “let it all,” then unzipped her skirt, “go.” Katrina’s plaid skirt fell to the floor.

“Well then,” she licked her lips, looking up into Gerald’s tantalizing green eyes. Katrina reached behind, unclasping the bra and shrugging the straps clear of her shoulders. Grinning wickedly, she drew her hands to her waist and lifting the elastic of her thong away, dropped the white panties to join with her skirt and bra.

“Very nice,” her brother grinned, his vision gobbling up the practically nude form of his sister.

“You mean it?” Katrina gasped excitedly. “You think I’m beautiful?”

“And fuckable,” he said, nodding. “Quite fuckable.”

“You’d fuck me?” she asked eagerly, her breathes short and hungry. “Would you? Could you?” A predatory gleam filled her eyes.

Do it, the voice yelled in exultation. No, I can’t! She’s my sister! It’s wrong!
