I can say that the stranger behaved with the brunette on the bus as if they had known each other for a long time. He laid around flatteredly while the girl was sucking his dick, and they fucked each other without any shyness. The damsel took a ride not only on the bus, but also felt the powerful bumps in her hole from the guy's stick.
The guy who stayed is clearly the winner. The threesome was hot. That's quite a sandwich these cuties made. Lucky for the guy, he got picked up by his girlfriends and the second competitor got off.
