Under the impression I am home alone, I begin masturbating in the hot tub. The water always makes me too horny to resist. I'm deep in ecstasy and oblivious when my step-brother starts recording me. He soon makes his presence known and threatens to tell the whole family that I've been fingering myself in the family hot tub. In desperation, I gives into my step-brother's demand for some sisterly love. I begin with some tongue and soon indulge in my step-brother's big cock. I gag, lick, and spit all over his stiff pole until he shoots all over my face and leaves my swimming in his cum.
