You walk in to find your girlfriend making out with your big-titty step sister, and your brain short-circuits. They tease you, asking if you really think it’s wrong—especially when they’re both so damn hot. Your step sister shakes her chest at you while your girlfriend pulls you closer, whispering that sharing is caring. You try to act mad, but your dick betrays you, harder than ever as they take turns touching you. One kiss leads to another, and soon you’re not just watching—you’re right in the middle, giving them exactly what they’ve been begging for. Guess three isn’t a crowd after all.
