Enraged, she storms in, pushing him onto the bed. Their bodies collide in a passionate, forbidden kiss, their hands frantically exploring each other's bodies. Lucas' massive cock presses against Cadence's thigh, and she can't resist, mounting him and sliding down his shaft with a moan. They fuck furiously, their taboo liaison spiraling into a wild, passionate confrontation, their family bond shattered by their insatiable lust.
