One day, my neighbor's older sister with a half-big ass invited me to have sex with her, and we had an incredibly euphoric sex session where we both came to orgasm. They both gave each other an aphrodisiac and pounded their thick butts into sex, and all the sperm inside his balls was sucked out by their pussies... The older sister was screaming and shaking her ass and going crazy. All I can think about is sex with my sister.
