My friend and I invited a little friend to play

Two couples, John and Sarah, and Michael and Lisa, are enjoying a night in at John's place. They've been drinking, and the conversation turns to sexual adventures. John admits he's always wanted to try a threesome. His wife, Sarah, teasingly suggests they invite their friends Michael and Lisa. They all laugh it off at first, but as the night goes on, the idea grows on them. They decide to call Michael and Lisa, who come over hesitantly but agree to consider it. After some negotiation, everyone gets naked in John's hot tub. Michael and Lisa are initially hesitant but eventually join in as John and Sarah kiss passionately. Soon, the foursome is engaging in steamy sex acts, including oral and intercourse. The camera captures their sweaty bodies colliding as moans and groans fill the air. The taboo of being caught in the act heightens their passion, their hearts racing as they give in to their desires.
