I think they couldn’t handle the heat. She titty fucked a lot of actors. She also didn’t let a lot of actors touch. That’s why her final movies are prime. The first Jerry scene is great for that. Freaking massive melons. Then the DP scene also has a lot of great scenes as she sucks and holds her giant tits together and then the cum scene…great. The threesomes kinda of sucked though. The lucky nerd got better as it progressed. He seemed nervous but then started enjoying himself and in return Nina got aroused and enjoyed it as well.
Like when Nina got off him and maybe they were heading for a break but he pulled her towards him and grabbed her tits and then sucked them. Dick slap her in the face plenty of times. All that got him the reward of being able to be one of the few to cum on her face and asked for him to do so.
Which shows that Nina’s true demeanor is being dominated even though she says otherwise.
Why through her whole career some called her lazy or a fuck doll because she didn’t plan on fucking someone, was expecting for the guy that is even lucky to fuck her.
. I guess too hot to suck on the titty from the tank top he just pulled out.
