Passionate Step-sister

He watched his step-sister, Katie, as she sleepily made her way to the kitchen. The thin white fabric of her nightgown flowed over her supple curves, and he couldn't help but fantasize about what lay beneath. As she poured herself a glass of orange juice, he noticed her full breasts swaying gently with each movement.Finally mustering up the courage, he walked over to her."Uh, Katie?" He hesitated, his heart racing in his chest."Can I talk to you for a moment?"She turned around, her hair messy and hanging over one eye. A small smile played on her lips as she took a sip of her juice."Sure, what's up?"He took a deep breath and stepped closer to her."I, uh... I've been wanting to tell you how beautiful you are for a very long time.
