Adrianna and Marilyn, innocent yet curious, find themselves in a taboo Valentine's encounter with their stepdad. They timidly touch each other, their fingers tracing delicate lines on soft skin, before Impure Desire joins, his experienced hands guiding their eager mouths onto his throbbing cock. The room echoes with wet, sloppy sounds as the stepsisters learn to deep-throat, their eyes watering but never breaking contact, while their stepdad's groans of pleasure spur them on.
