You Cum into Stacey with an idea

               Her soft lips and long tongue as she deep throats your cock trying to suck it for all it is worth until you cum once again inside her. As your long hard shaft is squeezed by her tongue with joy for cumming inside her. 

                Your mind snaps back to where you are and what is happening to you. As you look down at your friend Stacey the cowgirl sucking on your cock trying to get you to blow another load again.  

                 At first you have no idea what she is trying to do this will not help turn her back to her human self only leave her as the woman with huge breasts and an udder dripping milk all over the floor. As she keeps sucking on you as if her mind is that of a calf.

                 Than when you see the black cow like spots begin to show all over her soft smooth skin you realize she needs cum to keep the changes for going any more on her.  Though you don't know how you will be able to keep cumming for her and still live much longer your self.

                  That is when you get the idea to cast a spell to change where you are at the moment. As you cast the spell Stacey moos and you cum making you moan as part of the spell.
