I'm at the point where it is just too much work try and dig for it while sitting. Plus holding/ pushing it back with each stroke tires me out too fast.. But the weight of my belly and fupa along with a thrusting motion I can get it done easily, it makes a huge mess but fuck is it hot. And when I'm lying down I do have to roll on my side so my belly flops out of the way allowing me to reach.
