Tina’s Party (1977)

The video starts with a dark-haired girl, possibly Tina, in a close-up, not doing much but looking around. Then it cuts to her and another girl, blonde with curly hair, getting intimate on a couch, lots of touching and kissing. A guy joins them and they all sit close, still just chillin’. At some point, oral action happens, not super clear who’s doing what to whom but it’s girl-on-girl and possibly some jerk-off action. The camera’s mostly in close-up, so you get a good look at their faces and reactions. One girl’s got a pretty notable rack for her size. They all seem pretty into it, expressions are pretty relaxed and happy.
