wow!–no lack of movement yesterday–i was lying down on my back on a non session day and nodding off after about 1/2 hr when my ass started puckering violently ( i guess it was an anal orgasm)–it felt like my asshole was completely turned inside out very quickly and violently with no gradual buildup or warning–as a consequence i was caught unaware and could not help responding with a very hard contraction, trying to get control of my runaway ass, but i chased it away instead–there were 6 or 7 "volleys", one after the other with no breaks or difference in intensity–they were extremely pleasurable and just what i am looking for but unable to retain when they occur– if i could just learn to let these things continue so that i could enjoy them i would be a very happy man indeed
