My dream ! Did it once only, in 1992, but the fem did not have such a great body (she was an obese blonde). I came like never while she was masturbating my thick cock. I had my straight OPEN hand (yes!!) well 5cm inserted past the wrist, I did not think to close my fist, then I certainly could half of my forearm pushed inside her huge vagina ! She came too, squeezing my wrist whith her big opening cunt...
