A brother and sister, alone in the house, both horny and curious, decide to explore their desires. The sister, an insatiable squirter, starts fingering her wet pussy, her moans growing louder. The brother, jacking off in the next room, can't help but listen. He joins her, both of them naked and horny. The sister, her pussy dripping, begs him to fuck her. He resists, but she's insistent, her body convulsing with each squirt. They finally give in, fucking hard and fast, her juices squirting all over as they both reach climax.
