Lady Despina and lady Naomi were bored at home and they needed to have a little fun. The mistresses chose to use their jerk off instructions to have fun at the expense of this guy. The guy was excited as he thought that he was going to have sex with them but it never came to be as they were having fun at his expense. He was just made to jerk off as they watched.
This guy was having a hard time jerking off as he did not have something to make it all naughty for him. So this mistress helped him by giving him jerk off instructions. But beyond that, the mistress also helped the guy by spreading her legs and letting his imagination run wild even though she did not remove her clothes for him to see her pussy or even her thighs.
