A pretty Czech blonde and her boyfriend go pretty far

This pretty blonde and her boyfriend get approached while they're waiting for the bus. They first get offered money to just kiss but things escalate...the camera couple want to push their limits. Next they get the girl to show her tits and man, those are big and firm! How to go from there? How about a blowjob? How about the camera couple joining in? They go with it as long as they get paid that is...until he sees his girlfriend fucking someone else. They went pretty far though!
