Hey you mechanically inclined folk! Please help revise engineer this chocolate pump

[Kman34]

Suck lightly on the end of the tube.
Then, place your lips around the tube's end and suck like a straw. Pull the chocolate just over the rim of the container of chocolate. Once the chocolate reaches the arc of the tube, it will start to come down the tube. Move your mouth and insert the tube into the bucket.



I’m strangely turned on....
