Blonde Lesbian Fitness Instructor

I saw a full scene, possibly on XHamster, some months ago. It appeared to be by either Girlfriend Films or Sweetheart Video due to the similar production quality, but I can't be certain.

In it, there are two women in a bedroom. One is a peppy, physically fit blonde woman who is attempting to get a slightly out of shape lazy blonde woman to who the fit one is attempting to get into shape, but she's complaining about the amount of effort she has to put in. There is a bar fixed to the wall that they use for stretching at one point.

Eventually, after several tries trying to get the one girl to bend into position, the slow flirtation and the prompting for a "break" begins. One convinces the other and the disrobing and sex begins. Eventually, the fit one finds a way to incorporate the bar into the sex, lifting the lazy ones leg for some pussy licking. She uses her flexibility in many ways, including some interesting acts of tribadism. As the scene ends, the one girl comments on how she found a way to get the other to exercise.
