A wild young couple addicted to activities that contain a degree of danger decide to use that addiction to spice up there sex life. It starts out harmless enough where he dares her one night in a bar to get up on the bar counter and do an erotic dance and wind up topless at the end of it. She then dares him to make a sexual proposition a female cop by inviting her to his hotel room for a half hour of wild sex. (She makes him promise that if she was crazy enough to agree she would have to join them)
Each dare if completed as proposed is rewarded by the one who came up with the dare to surrender their will and body to the other by agreeing to satisfy any sexual desire they have regardless of how vanilla or how outrageous it is.
As this behavior continues the dares escalate. Since she can't swim he dares her to jump into a pool in water well over her head and then splash around screaming for help until someone rescues her. She dares him one night to pick a fight with the biggest guy in the bar.
It continues until they both agree to act together in the kidnapping of a woman for him and a guy for her who they take to a secluded cabin he recently inherited and they both watch the other as they force their victims into having sex at first before the sexual demands each makes their victims perform become more and more outrageous as well.
The activities involved in this role play can be discussed beforehand.
