In the dimly lit confines of their shared room, two siblings find themselves drawn to each other's bodies, their curiosity piqued by the forbidden. The younger sister, her eyes wide with innocence, tentatively reaches out to touch her brother's hardening cock through his pajama pants. He gasps, his body tensing as she explores his length, her touch tentative yet eager. Meanwhile, he reaches around to cup her breast, feeling its weight and softness through her thin nightgown. Their breaths grow ragged as they continue to touch, their bodies aching with a need they've never experienced before.
