The house empty, Gina Monelli lets her desires consume her. She slips on a strap-on, the thickness pressing against her clit, sending waves of pleasure through her. She fingers her wet pussy, her mind filled with images of her sister's untouched cunt. She licks her sister's ass, then pussy, before plunging the strap-on deep inside, fucking her sister's pussy until they both squirt, their orgasms filling the house with their lewd cries.
