I have seen a few posters asking about CIM or will not visit the SP. For me I enjoy it as there is still stimulation while cumming so it intensifies it. I do not enjoy it much when you mention that you are about to cum and all the sudden the SP just stops all movement or weak HJ. I know a couple of SPs who do not allow CIM but cup the little head ( did not want anyone thinking cupping the big head ) with their hand and do a swirling motion to continue the stimulation and it works well. Do some people do it just for the fact of cuming in someones mouth ( erotic ? ) or are all due to the sensation?
