The threesome starts innocently enough, but as the men focus on the women, one of the ladies can't help but notice the other man's impressive bulge. Her bisexual curiosity piqued, she reaches out, touching it through his pants. He responds, his cock twitching, and she takes it as an invitation, unzipping him and taking his throbbing member into her mouth. Her partner watches, frozen in surprise, as she enthusiastically sucks another man's cock for the first time, the room echoing with the wet sounds of her oral exploration.
