I have always wanted to slit a good, hard six pack just deep enough to go into his guts and belly fuck him and have the same done to me. It would be relatively bloody and a FANTASTIC mutual fuck that could heal and be done again down the road. I have always wanted to feel a cock in my intestines and mine in another guy's and cumming in eachother's belly along with a bunch belly/navel stabs into eachother. My plan would be for some mutual belly stabbing using small blades till one or the other says "stop", he gets the first gut stab with a slit big enough for a good, tight fuck and then the other reciprocates. After cumming, a couple more belly stabs to eachother and pressing our bodies together, bleeding together and enjoying the ecstacy of belly pain and plenty of blood.
