I hate it when I'm constipated and the solid shit presses against my prostate and I'm trying to evict the little bastard before it makes me cum but my ring can't expand fast enough and so I bleed from the effort yet still end up cumming on the tiles and I can't help but straighten my legs as all this happens but that changes the position of the poo which makes the pain worse so I wince and try to stand up to get away from it and fuck my rectum up more while cumming down the wall.
