In the confines of their shared room, siblings struggle with their burgeoning lust. The brother's cock tents his pants, while the sister's nipples harden against her thin shirt. They try to distract themselves, but the air is thick with tension. When the brother's hand accidentally brushes his sister's thigh, they both gasp. Their eyes meet, and the dam breaks. They explore each other's bodies, the sister worshipping her brother's cock, the brother marveling at his sister's tight, wet pussy. They fuck hard and fast, their bodies slapping together, until they collapse in a spent heap, their secret safe, for now.
