Anal Sex

Posted by:

Did you know???...Two muscle rings called sphincters surround the anal opening. Each functions independently. The external sphincter is controlled by the central nervous system - just like the muscles of the hand, for example. You can readily tense and relax this sphincter whenever you want. The internal sphincter is quite different. This muscle is controlled by the involuntary or autonomic part of the nervous system, which governs such functions as heartbeat and stress response. Anyway... I didn't find the answer to "Why I scream like crazy when I'm anally penetrated???" hehehehe Videos of this ho session of course @ http://sites.redclouds.com/latinvideo/
