In a dimly lit room, couples take their places, eyes locked on the Sybian machines awaiting them. The first woman mounts her machine, her partner controlling the speeds as she bucks and writhes, her cries of ecstasy filling the air. Meanwhile, her partner's hands wander, teasing her breasts, her clit, as she edges closer to climax. The room is alive with the sounds of pleasure, the scent of sex, as each couple takes their turn, the tension building towards the inevitable explosion of bodies and limbs in a heaving, panting mass of flesh.
