My Dominant(Mistress) absolutely loved this. We used a water-based lube and rubbed it around the inside of the toy to prep it. I teased her cock for a while, and then I started the robojuicer. I started slow and towards the tip of her cock, then slowly worked my way further down her shaft as she moaned with pleasure. I slowly started going up and down her shaft, watching her face light up as I got closer to her tip, then held it there as she squirmed and moaned. She let out the most primal moan of ecstasy as she shot her load onto my tits. Needless to say, this is a great masturbator.
