We pick up college couples in the street and offer them a travel voucher worth 300,000 yen if they can endure tickling for 5 minutes. At first, they try to resist, but gradually escalate. Even though their boyfriend is behind them, they are tormented by their sensitive parts, their bodies contort, and moans leak out. Eventually, they are betrayed by their boyfriend in a situation where they are only 30 cm apart through the mirror.
