A male-female pair is challenged to participate in a certain game!
Hearing that they could win 100,000 yen if they succeed, the two eagerly followed along.
However, the challenge was to "accumulate 100ml of saliva just by kissing"…
The two are bewildered by the absurd task.
The amount of 100,000 yen aside, men who get excited about the prospect of kissing a beautiful girl will eagerly try it.
A somewhat troubled girl accepts and starts kissing, but gets excited as the act escalates…
To escape, she has to gather saliva... What will be the result!
