So you wanted to play with the little witch now- didn't you? Maybe I can brew you up the potion that you desire, but i have my rules too... a witch needs to get what she wants. So you give me what I want and I will brew you any potion you want me to! But first- sip on this!  You're feeling more relaxed; you're feeling very compliant now. In my trance... perhaps this was not the special brew that you were looking for- but it is the brew that you will be taking for now! Feel that- I'm sure you've noticed by now that stirring and hardening cock now. I'm going to instruct you carefully on how to stroke and rub that stiff cock- and at the end when I drain every last drop from you... you will be mine!
