Unbeknownst to me, my step cousin, a raven-haired vixen with an insatiable appetite, had been eyeing my package all day. As I lounged on the couch, she sauntered in, her eyes locked onto my crotch. Without a word, she straddled me, her skirt hiking up to reveal her lacy panties. I could feel the heat radiating from her pussy as she ground against me, her breath hot on my ear. "I've been waiting for this all day," she whispered, before sliding her panties aside and impaling herself on my rock-hard cock.
