Hidden away in their family home, an incestuous spark ignites between an amateur couple, brother and sister, as they explore their secret desires. The girl, a young, innocent-looking brunette, teases her brother with subtle touches and whispered words. Her brother, a strapping man with a perpetual five o'clock shadow, grows harder by the second, his bulge noticeably tenting his jeans. In the throes of passion, they forget about the world around them, lost in their taboo dance of lust.
