I play with my anal toys more often than I get the chance for a good fucking, but today I just realized something. I have a nice 9" dildo (and I used to have a 20" snake), and I can really feel it when my deep inner sphincter opens and the head slides right into my colon. This occurs about 8 inches into my ass. Once it is open I have been able to get the 20 incher in up to about 12". I also have a really good friend who will fuck me once a month or so, who has a true 9 inch dick. When he says he is all the way in, I can say that I never noticed that he opened up my inner sphincter. Do you suppose he is not actually getting in all the way? Or am I just feeling his natural dick differently? Maybe I should push the snake deep in before letting him into my ass. Once opened for him, it might feel really great to have him stroking deep into my sigmoid.
