The automated rhythm of the camera captures May and her brother as they succumb to their darkest urges, the narrow closet space their only sanctuary from prying eyes.

May's moans fill the tiny space, her pleasure echoing as she grinds against her brother's throbbing erection, their shared taboo pushing them ever closer to the edge of ecstasy.
