In the dim glow of their shared room, an amateur couple, siblings by blood, find themselves drawn to each other's bodies. The brother, his cock tenting his pajamas, watches his sister undress, her curves on full display. She catches him staring, her nipples hardening at the attention. They're both inexperienced, their bodies aching for touch. She tentatively reaches out, brushing his cock through his pants, feeling it throb at her touch. He mirrors her, cupping her breast, his thumb grazing her nipple. Their bodies press together, clothing still separating them, as they explore this new, forbidden territory.
