In the crazy world of Japanese Competitive Denial games a draw between the two girls competing (where neither could force the other to cum after an hour of bound 69) would lead to the Cockroach Blow Off tie breaker.
Not only did the loser have to eat the cockroach, but she would be the winner’s denial pet for the next week.
I guess it would get that taste out of her mouth.
