Sounds weird, but it’s super powerful at building sexual tension and literally making you want to rip your clothes off.
You are not allowed to have sex in this game… You are to try and entice your partner into initiating sex with you, while he is doing the exact same thing to you, that’s like wetting each other’s appetite. You lose when you give in and actually initiate sex. The winner is the partner who holds out the longest.
It’s very good at building sexual tension, anticipation and arousal.
You could even make a bet for the winner to take.
