In the dim light of the closet, the siblings' breaths mingle, their hearts pounding in sync. Michelle's hands tremble as she reaches out, tracing the outline of her brother's cock through his thin pajama pants. He sucks in a sharp breath, his hips jerking forward. Their eyes meet, a silent understanding passing between them. They're playing with fire, they know, but the pull is too strong to resist. Slowly, they begin to undress each other, their movements clumsy with anticipation. When they're finally naked, they pause, taking in each other's bodies. Then, with a soft moan, Michelle guides her brother's cock to her entrance, and they cross the point of no return, their bodies moving together in a dance as old as time.
