Invasion of the Bee Girls (1973) (BDRip)
One of the girls in the back row is quietly jerking off with her hand inside her jeans. She’s wearing glasses, dark brown long hair, slim build, and keeps her head slightly down like she doesn’t want to be obvious. The other two girls — one blonde, one darker brunette — are just sitting there, not touching themselves, facing forward like they’re watching the screen. The guy in front has thinning hair, maybe 40s, dressed like an office worker, arms crossed, not reacting at all. Camera stays wide for most of it, making the handjob subtle but visible in the dim glow from the screen. Close-ups don’t show faces in detail, but you get clear shots of her hand moving in her lap, fingers pressing through the denim. Lighting is super low, almost blue-black, adds to the voyeuristic feel. No sounds, but the way she shifts her leg suggests she’s actually getting off. Nothing else happens — no stripping, no switching seats, no contact between them — just her slow, steady motion under the cover of darkness.
