This takes place when you're getting a rimmer, and at the moment her lips are directly over your asshole, you fart into her mouth and watch her cheeks inflate like a hot air balloon. - Tommy, Matt, Bryan, & Tony, Texas
Hot air balloons are the oldest successful human flight technology, dating back to the Montgolfier brothers' invention in Annonay, France in 1783. The first flight carrying humans was made on November 21, 1783, in Paris by Pilâtre de Rozier and the Marquis d'Arlandes. Hot air balloons that can be propelled through the air rather than just being carried along by the wind are known as airships or, more specifically, thermal airships.
