Serenity's passion for big black cocks leads to humiliating cuckold experience

Serenity has always been a fan of big black cocks, but her husband doesn't quite share her tastes. One day, she stumbles upon a black bull in a cage and can't resist the urge to ride it. Her husband walks in on her, and instead of being angry, he decides to join in on the fun. He locks her in the cage, leaving her there for days, only allowing her to suck his friend's cock when he comes over. When her husband isn't around, she's left to pleasure the black bull, her cries of pleasure echoing through the empty house. When her husband returns, he forces her to perform for him, making her beg for his friend's cock. The humiliation is intense, but the pleasure she experiences from riding the black bull and sucking his massive cock is too great to resist. The cuckoldry continues, with her husband bringing more black men to share her, each one leaving her more humiliated and satisfied than the last.
