Pain, and pleasure. A sexy, on the edge pain. The burning and slight sting of stretching - the sense that everything between my anus and clit is full to the max. Despite the fact that it is on the verge of discomfort, it feels so good! Then the incredible sense of being filled that takes my breath away every time. The wonderful pressure of the shaft against my clit as he penetrates, and the even more wonderful pressure against the hidden part of my clit as he pulls back. And - the most satisfying, transformative aspect of big cock - the internal pressure. A big cock can actually make your inner organs move! A very small amount, but movement nonetheless. A big cock can put pressure on the peritoneum which results in the most awesome, mind-blowing satisfaction! It feels like the powerful phallus is right up by the breastbone. It isn’t, obviously, though the pressure that is placed on the peritoneum creates movement that can be felt, creating that illusion. I get goosebumps, I whimper with butterflies in my chest, and I come so hard!
