In the dim light of their shared bedroom, siblings Alex and Emma find themselves alone and horny. Emma tentatively touches herself, her fingers tracing her wet slit as she bites her lip. Alex, noticing her, joins in, his hand stroking his hard cock. They lock eyes, the tension palpable. Emma, emboldened, asks Alex to touch her, to make her come. He obliges, his fingers replacing hers, plunging into her depths. She moans, her body writhing as he expertly brings her to orgasm. They freeze as their parents' footsteps approach, their secret moment cut short.
