Mistress Fiona teased this guy, facesat on him and even tried to lick his dick and she did it while he was wearing a chastity device. She was doing it as an experiment as she wanted to know what would happen in that instance but she also did it to humiliate him and have fun at his expense. The guy had no choice but to endure what she did to him.
Mistress Fiona wanted to find out how effective this chastity device was and that is why she chose to try it on a loser. The mistress facesat on him and she even tried to give him a blowjob. That was when she realized that it was very effective since he could not get a full hard-on and he could not do anything with his dick other than to pee with it.
Goddess Fiona had caged her boyfriend's dick and he had never had any action for a few days. She knew he could not even play with it. So she went and she opened his dick lock but she did not free it completely. Instead, she had the top to herself and she sucked and licked it while she sat on his face and he reciprocated by licking her pussy. He did it so good that she opened the cock lock.
