Ladies do you help out and spread your asshole open for your mans cock or tongue? If so in what position are you, on all fours or on you back with your legs over his shoulders. I myself take my index fingers on both hands and insert into said asshole (wifes) and spread it open for my toungue. Curious what you girls do to help!
I think your question is a little more based in fantasy. In reality my guess is that the guy just does the penetrating. An asshole isn't something that needs to be held open for anal sex to take place...
I've had chicks gape their ass open to the point you could actually drop a golf ball in. It looks like a fat man singing opera. Check out Max Hardcore he is the kind of gapers! (__*__) + ==D = (__O__)
