MMF movies where the second guy shows up in the middle

[VictorG]

Specifically I like the "amateur" stuff where a second guy comes into the room while the girl is sucking or fucking and she's thrown off by his presence. He might join in or he might just watch, but its her being interrupted that I like. this one is a good example at about the 2:50 mark
