In the cramped confines of the airplane bathroom, Mister Neighbour's thick cock stretches Miss Neighbour's mouth wide as she hungrily sucks him off. Her hands stroke his length, matching the rhythm of the plane's vibrations. As he nears climax, she pulls back, letting his hot cum spray across her face and tits, marking her as his. They quickly clean up, returning to their seats just as the 'Fasten Seatbelt' sign illuminates, leaving them to exchange secret smiles and wet dreams of their next airborne adventure.
