Tight pussy

I want to be fisted but my pussy is still to tight and hubby's hands are too big. we keep keep trying and have gotten little more each time but still can't get the whole fist in and fuck me with it. I want to be able to have it sliding in and out of my tight wet pussy. This past weekend we got it almost but not all the way in but farther then before and it made me squirt and cum all over his hand, arm, and face... etc
