Terrified Alexa Samara seeks solace in her stepsister Darcy Orduz's embrace, but the comfort she finds is far from sisterly. Darcy's massive black cock stirs, tenting her shorts, as she holds Alexa close. The frightened girl looks down, eyes wide at the sight of her sister's enormous, hardening cock. Darcy, overcome with lust, guides Alexa's hand to her thick shaft. Alexa, despite her initial shock, finds herself stroking Darcy's cock, feeling its heat and throbbing pulse. Darcy's hands roam Alexa's body, cupping her big tits and squeezing her big ass. Alexa, now excited, takes Darcy's cock out, licking her lips at the sight of the big, black dick. She takes it into her mouth, gagging slightly as it hits the back of her throat. Darcy pushes Alexa back onto the bed, spreading her legs to reveal her wet, shaved pussy. She rubs her big cock along Alexa's slit, making her moan. Slowly, she pushes inside, filling Alexa completely. Alexa gasps, her big tits heaving as Darcy starts to fuck her, her big ass slapping against Darcy's thighs. Darcy pounds her, harder and harder, until she feels her sister's pussy convulsing around her cock. She pulls out, thick ropes of cum shooting onto Alexa's stomach and tits.
