Latina with nice ass fucked in spin class

No woman would imagine getting fucked in the spin class. Who was going to tell this Latina with a good ass that the class monitor would end up embedding it while giving the pedaling? The aunts who are with her leave quickly when the monitor tells them to turn around, that she has things to discuss privately with the Latina. The guy keeps nailing her from behind while he grabs that ass and then tells him to ride until he gets the semen because that's the best training to get in shape.
