John's casual offer turns into a reality when Mike, eager to win the bet, dives in, kissing Sarah deeply. She stiffens, shocked, but Mike's persistence ignites her curiosity. John watches, his cock straining against his pants, as Mike strips Sarah, revealing her firm tits and shaved pussy. Mike licks her, making her writhe, then slides his cock in, fucking her hard while she sucks John. The room fills with their filthy sounds, Sarah's body betraying her as she craves more, her tight pussy clenching around Mike's cock, ready for more than just a bet.
