A project where we ask pairs of men and women to challenge a certain game!
When the two heard that they could win 100,000 yen if they succeeded in the challenge, they eagerly followed along.
However, the challenge was to collect 100ml of saliva just by kissing.
The two are confused by the unusual topic.

He started kissing her for money, but his feelings gradually grew stronger and he started taking off his clothes.
Before you know it, you will be in a lewd state where you will be crazy about having sex!?
The only way to escape is to collect saliva... but what is the result?
