My ultimate fantasy: Me lying on the floor, hands tied and stretched far above my head. You take a sharpened/shortened ice pick about 2.5" long, place one hand on my chest to hold me down, place the tip of the ice pick on the center of my abs halfway between the navel and sternum, then sloooowly push it into my abs to the hilt. Then slowly pull it halfway out and quickly push it back in, and leave it there till I cum.
Alternatively we could stand up and mutually stab each other if you like the same thing. Safe play only...no trading ice picks, and no more than two holes.
Stabbing myself with small needles.
