The second part of the medical examination continues as both Mistress test the cock reflexes of their sub, sissy cock with a number of pin wheels. The pin wheels are also used to stimulate his sense of feel in the cock. Their intent is to sadistically -medically enhance his cock using pegs to stretch the foreskin which will allow plenty of room for the head of the cock to grow. Only upon successful growth of the cock will this sub be able to satisfy both mistresses who will consider granting him a little vibrating pleasure for their satisfaction.
