John had decided long ago what kind of MILF he wanted to be. He was going to keep the dial set low, just to 1, enough to change his body but not reality. Most reports consistently said that caramel produced a Middle Eastern, Persian sort of MILF. Big, full breasts would be more likely if the brew contained soya milk, avoiding dairy milk that would cause undesired lactation. There were multiple unsubstantiated accounts of nutmeg ensuring a particularly beautiful, attractive MILF. And finally, a particularly niche rumour John had decided to test, maple syrup would give the MILF a very sexy upper class English accent.
He blended all of this together, put it in the filter, set the device to 1 and set it a-whirring. What John didn't know was quite a few things. The dial was faulty; what looked like 1 was actually halfway between 3 and 4. Nutmeg did not ensure an attractive MILF, what its actual effect was to invert the spell effect, and thus rather than a MILF powerfully attractive to under 25s, it left the drinker an 18 year old girl powerfully attractive to over 25s. The device hadn't been programmed with maple syrup in mind, and so it just threw out some random alterations to John and to reality. The caramel and soya milk did work, though.
John drained the coffee in one long draught, laying down on his bed and falling into a restful sleep as the magic began to work.
