Finger your Bum 4ever hack!

Ok so I recently found a hack that allows me to finger my ass forever (all day) even at work. Ok so I inserted my thumb in my ass (because its the biggest finger) and then I cut my thumb off with a kitchen knife. Make sure to clean the knife to prevent infections and sepsis! And now its in there forever. It feels sooooo GOODD! I cum everytime I sit down, because the thumb gets shoved deeper inside. Ladies, gents and genties, dont seperate work and pleasure anymore with this simple hack!
