Caution, Extreme! My Fist Is Not Enough for MILF Karina, She Want’s My Foot?

At one of our sex meetings, Karina wanted to be fisted again - her husband and I take turns with our big hands, but somehow that's not enough for her. So she tells us that she would like to have a foot, including a shoe, in her pussy! First, we try it only with her high heels, which work quite well - but they are also smaller than mine. Even with a lot of lube, my foot with heels just will not fit in there. But without high heels, it works all the better, and the foot in the nylon stocking slips at least half inside ;)
