"Oh god, Alex… why is it so hard?" Julie said, her eyes widening as she stared at my painfully throbbing cock, the thick shaft standing straight up, veins bulging and the head already glistening with fresh precum.
"It's because of you, sis," I replied, my voice low and rough.
"Does my body excite you this much?" she asked softly, her hand gently wrapping around my girth.
She started feeling it, her soft palm sliding slowly up and down the length, exploring its thickness and heat with curious, almost reverent touches.
"Ahhh… yeah, sis," I groaned, the sensation of her warm hand on my cock sending waves of pleasure through me.
"Remove your clothes, Alex," she said, her voice turning more commanding yet still teasing.
I got up on the bed, quickly pulling my t-shirt off and sliding my shorts all the way down, letting them fall to the floor. Now completely naked, my hard cock stood proudly between us.
