3kg of rocks stuffed into my guts til I cum from it 7 times

Stuffing my rectum and guts so full with heavy rocks that the pressure it puts on my prostate makes me cum spontaneously hands free. Then shoving hi speed vibrator wand up my hole with the rocks makes me have a few more intense anal orgasms before using it on my cock to make me have 2 more ruined cumloads out while my insides are full of rocks
