Can you full this up to the top?. Dr Lucy takes your cock into her hands and starts working her magic on your manhood. As her professional hands move quickly up and down your shaft ever so gently, you watch her yummy titties bounce up and down under her silky satin blouse. She suggests that for the best results and for a bigger amount to come out, she should stimulate your male G-spot by introducing her fingers up inside your asshole while she milks you like a cow...

Dr Lucy sees that you are nearly ready for your donation sample and prepares the sperm cup but first takes it all into her warm mouth to better conserve the sample and slowly introduce it into the sample cup like a true professional.
