Shrinking you with Magic Milk JOI

Description: You don't know this about me, but i've actually got a bit of magic. i seduce you into my home like the good neighbour i am, and fool you with my persona of nice friendly banter. before long though i'm seducing you with my breasts, theyre thick and heavy with milk. magic milk. i tell you i want us to milk eachother. i want to milk your cock, and i want you to drink my milk. you agree, as you have a serious lactation fetish. theres no way i could know that though, right?  before you know it you start to shrink. smaller and smaller and smaller you get, and i keep instructing you to stroke your cock for me as you shrink further down, reaching different areas of my body as you go.i explain it was my milk that did this, it's a magic potion and only i can stop it. i tell you i want your milk and for you to worship my body or i won't make it stop. eventually i let you cum, counting you down to cum on my tongue. once you do, i inform you that cumming was the answer to the spell, and you will stay this size forever as my pet!
