Kylie Quinn, the insatiably curious stepsister, can't help but wonder about the mysterious cock she's never touched. Today, she's determined to learn. She corners Jax Slayher, her stepbrother, in the living room, her eyes locked onto his growing bulge. 'I just want to know how it works,' she purrs, her hand already reaching out. Jax, torn between brotherly duty and his own lust, lets her explore, her small hands wrapping around his shaft, her mouth soon following, eager to learn the taste of cock.
