As the siblings huddle together in the cramped closet, their bodies pressed close, they can't ignore the heat building between them. The brother's massive cock tents his pants, and the sister can't help but rub against it, feeling it twitch and grow harder.

He sucks in a breath, his hands going to her hips, pulling her closer as they both give in to their forbidden lust.
