I felt Larry withdraw his hands at the same time that he began pressing on my back, obviously to get me to roll over on my stomach. When he made contact with my ass again I could feel him rubbing and smearing something greasy or slippery all in and around my hole. It made his fingers slide in even easier and soon he had all three ravaging me deliciously again. Just as I was really falling into Larry's rhythm, he stopped and withdrew his fingers. Before I even had time to consider what was happening I felt Larry throw a leg over me just below my hips. Then I felt what was unmistakably the head of Larry's penis, this time pressing dead center on my newly loosened hole. Nonetheless, perhaps due to my recollection of how it felt filling my mouth earlier, I clinched tightly just as Larry pressed firmly against my hole. Larry leaned over my back and whispered in my ear, "Push out hard, sort of like when you go to the bathroom". I did what Larry said just as he increased his pressure slightly. I was totally shocked to feel the enormous head of his penis sort of slide by the tight place at the outside of my hole. However, the shaft of his penis behind the head felt twice as big and I sort of let out a little groan as it pressed to stretch my hole way beyond what Larry had done with his fingers.
Larry stopped there and began to just oscillate his penis slightly back and forth, gaining a little more ground with each stroke. I recovered enough from my mixture of panic and sensory overload to remember the "pushing" thing. I began to push out for Larry each time he made one of his slight thrusts forward. We began to sense each other's rhythm and eventually Larry had gotten to a point where the larger part of his shaft was definitely penetrating my ass. I was delirious. The sensation of having my asshole stretched was an incredible combination of pressure, slight pain and the most intense pleasure I'd ever felt. I thought that was as fantastic as anything could feel, then began to notice, on top of all that, the immense sense of fullness inside me as Larry's huge penis began to actually fill me up inside.
Remembering this afternoon Larry's penis had appeared to reach nearly to his knee, I wondered just how much of it he would or could force into me. It felt to me like Larry's penis was already reaching nearly to my stomach. At some point, I felt Larry hit some definite resistance, creating a slightly painful dull ache deep in my belly each time he pressed against it. I groaned again as Larry must have sensed he had "bottomed out". Then Larry began to withdraw his penis in one ever so slow stroke. The feeling of so much of his veined length rubbing past my tight outer muscle was so glorious my head started spinning and I really almost fainted. I must have been hyperventilating through most of Larry's withdrawal. As Larry reached the end of his long tortuous backstroke I focused on getting my breathing back as nearly as I could to normal. Just as I stopped seeing stars and thought I might get control, Larry reversed direction and began just as slowly to fill me up again. This was the most intense, heavenly sensation I had ever felt. The feelings around my hole from the friction, together with the pressure throughout my abdomen as Larry filled me up again until he just hit that little aching spot again, were incredible.
As I gained control of my breathing and got past the fear of literally passing out, Larry began to repeat the long complete thrusts over and over. He went very slowly at first. Then I began to realize he was picking up speed slightly with each stroke. Eventually he was ramming me fairly quickly and forcibly. The sweet dull ache that I had first felt just at the end of each stroke now became one long wonderful sensation as his enormous thing filled me so quickly with each thrust. The wonderful feelings mixed with the little achy feeling as he plowed into me reminded me a lot of the spasms I felt when in the throes of an orgasm. Just as I had that thought, I actually exploded into an orgasm without even touching myself.
This had the effect of making me clench tighter around Larry's penis, which made the sensations of his assault even stronger. This, in turn, made the orgasm still stronger. I ended up cumming over and over with more force than I ever thought possible, all the while being ravaged very forcibly now by Larry. I saw stars again and was outside myself with pleasure. I simply never thought anything on this earth could feel this wonderful. In the midst of all this Larry groaned suddenly and I felt my hole stretch even more as I swear I felt his cum shooting against me deep within my bowels. After a time Larry just collapsed his sweaty body across my back and sort of enveloped me, breathing raggedly against my neck.
Larry stayed deep in my ass and softened only slightly. It must have been the aftereffect of all the excitement, but I actually drifted off for a few moments. Then I woke up to the sensations of Larry wiping up the slippery stuff from my swollen and tender rear end. He then pulled the covers up over me, patted my ass softly, and rolled over leaving me there to rethink all that had just happened before drifting off again.
