The sisters, bound by their shared secret, retreat to the privacy of their chambers, their hearts pounding with each stolen glance at their brother's bulge. They dream of the forbidden, their hands wandering under their shifts, their breaths coming in ragged gasps. The brother, tormented by his own lust, enters their room, finding them entwined, their bodies damp with sweat and desire. He can't resist, and neither can they, as they succumb to the taboo, their bodies joining in a dance of sin and salvation.
