Under the guise of wrapping gifts, Emma's family's teen siblings, Emma and Alex, find themselves alone and bored. Emma, with her perky tits barely contained in her revealing top, starts touching herself under the table, her eyes fluttering as she imagines Alex's hands on her. Alex, catching her, playfully joins in, stroking his growing erection through his jeans. They share heated glances, their breathing syncing as they pleasure themselves, their mutual masturbation growing more intense with each passing moment.
