Minha pequena meia-irmã acidentalmente me dá Viagra e eu acabo gozando na boca dela.

My little stepsister very gently offers me a delicious aphrodisiac juice that she knows I like a lot, what she doesn't know is that instead of adding sweetener, she gets confused and gives me my stepfather's Viagra, that makes me horny and fuck her very hard and cum in her mouth.
