The art of making love to a variety of baked goods. i.e french Baguettes, pita bread, loafs, muffins, crumpets, custard creams and all other sexually attractive baked goods.
Stuart found a stale french baguette in his bread bin and began masturbaking. To his horror it was soggy because his dad had already masturbaked in it earier that day.
"Stuart!, what are you doing with that bakery item?"
"Piss off Dad, I'm Masturbaking!"
