Gas Pump Girls (1979)

This one’s a straightforward outdoor sex scene. Two blonde girls in their 20s, one with a long slim build in an orange top and the other with a short slim build in an orange top, are the main attraction. They’re joined by a short muscular blonde guy in his 20s. The scene starts with them interacting at a gas station, then moves to an indoor store and possibly a garage. The girl in the orange top gives the guy a blowjob, then they move to more. The camera captures everything up close, especially the oral scenes. The girls have great energy, and their body types contrast nicely.
