In our continuing scientific research into the effects of sex machines on hot MILFs we engaged the services of Kristyna. She was excited but a little apprehensive about putting herself at the mercy of the machine especially after seeing the giant rotating cock. But she took to the machine like the hot woman we thought she would be. We started her out slow, even letting her keep all her clothes on and just using he small vibrating pad on her pussy as we slowly increased and decreased the speed. She said she could handle more action but was really getting overheated so in the interest of safety she was soon naked and the giant cock inside her pussy. Of course, the old guy put the cameras on automatic and went behind her to play with her beautiful tits. Needless to say, but we will say it, she had a series of beautiful, loud climaxes. One of best research projects yet.
