He shoved almost the whole hand into me as I lay on the sofa

As I lay on the sofa and played with my cell phone - shortly after I had masturbated because I was reading such a damn erotic book - my partner came, started playing with my pussy, and then gradually just shoved his hand inside me. You can't even describe the feeling, like when something down there spreads and presses so much - so sharp! I didn't think it was so awesome and felt so damn good! Next time I really want to have the complete hand inside me - so a real fisting.
