An office lady is on a flight at the end of a business trip, and she is feeling horny. Unable to resist the urge, she secretly watches an AV on her phone, while a pleasant young man goes to sit beside her.

Starting a casual chat with him, she accidentally embarrasses herself but he's surprisingly cool with it; so she gradually starts making advances and they begin touching each other. One thing leads to another without the flight attendants noticing, and finally unable to hold back any longer, this thirsty onee-san invites him to join the mile high club with her in the airplane lavatory.

Heart-pounding, hidden in-flight sex ensues!
