The siblings, left alone in the house, can't resist the temptation any longer. The brother, his cock rock hard, watches as his sister, her body clad only in a thin nightgown, takes his length into her hands. She works him expertly, her small hand wrapping around his thick shaft, her thumb rubbing the sensitive head. His hips buck, pushing his cock further into her grip, until he can't hold back any longer. With a guttural moan, he comes, his cum shooting out in thick streams, coating her hands and leaving them both breathless.
