My wife also enjoys anal sex and has been getting her asshole fucked for 4 years now...not nearly the anal freak that the first girl I mentioned was. My wife, upon me pulling out of her asshole, will slightly contract her sphincter but it will still stay open also. I notice this especially when she is in mish or is squatting above me ready to sit her asshole back down on my cock. She doesn't gape when in doggy...it gapes to about the size of a pencil eraser when in doggy. When she is in mish or cowgirl her gape is about the size of a quarter. Basically I notice the more you tease and repeatedly pull out and put your cock back in the more relaxed or "used" the sphincter becomes. Also I seem to have success with rimming...lick and asshole for awhile and start to press your tongue onto it firmly and before long you will have a nice opening in the asshole to "tongue fuck."
