Young girl pleasures herself under stepfather's observation, resulting in ejaculation

A young, blonde-haired girl found herself alone with her stepfather on the couch, feeling a strong urge to pleasure herself. She began to strip off her lingerie, revealing her big, round ass, which she proceeded to massage with her hand. As she continued to touch herself, her stepfather couldn't help but watch in fascination. The sight of her naked body and the way she was pleasuring herself was too much for him to resist, and he reached down to unbutton his pants, revealing his throbbing manhood. He then began to stroke it while watching her, until he finally released a huge load, covering his pants and the sofa beneath him. The sight of her pleasureing herself was enough to make him cum, leaving both of them satisfied and filled with the knowledge of what had just transpired.
