Ofelia has a problem that affects her sexual life seriously: because of her strong vomiting reflex she is not able to suck her boyfriend's cock properly. That is why she makes an appointment to a sexologist. Fiddler is quite a qualified specialist. He has developed a program to deal with such unpleasant cases. As a part of this program, he ties his patient up with ropes making a nice eight figured rope bra. This way, Ofelia has to be obedient and pass the training. The leather collar around her neck also creates suitable atmosphere. When she is well fixed, Fiddler suggests her to try several gags of different thickness and size, starting with a small one. At first, the doctor simply shuts the girl's mouth with the gag and lets her rest like this, then, after she gets used to it, he replaces the gag with a bigger one, and so on. At the moment when Ofelia gets an inflatable gag, Fiddler slowly begins to pump it fullfilling her mouth completely. As soon as the patient is comfortable with that, the sexologist puts a ring gag on her After that, he puts Ofelia in a hogtie position and walks away. The patient is now left alone so that her mouth gets used to such a big and thick gag, as well as her boyfriend's dick. We bet she will do excellent blowjobs from now on.
