She’s getting fucked hard in the lab while he watches

It’s a lab, kinda dim, with a poster on the wall and some equipment. One woman in a white coat is standing there, kinda back turned, and another woman is getting fucked hard by someone off-screen. You can see the green liquid in the syringe, like it’s part of the scene. The guy watching has messy hair, looks intense. It’s not pretty, it’s raw. The woman getting fucked is moaning, the guy watching is focused. The whole vibe is sweaty, urgent, like they’re not playing around. The lab setting adds weirdness — it’s not where you expect this to happen. You can feel the heat, the tension, the way they’re all just in it together. No fancy words, just what’s happening. Real, messy, and hot.
