Gabyvany, always the curious one, can't help but notice her brother Alex's growing cock whenever they're together. One day, as they sit on the couch watching TV, Gabyvany's hand finds its way to Alex's crotch, feeling his hardness through his jeans. Alex, initially shocked, soon gives in to the pleasure, his cock throbbing in his sister's grip. They exchange heated glances, their bodies aching for more, but the sound of their mother's car pulling into the driveway forces them to retreat to their respective rooms, leaving them both yearning for the forbidden touch they've shared.
