Day 4 -
I hope you are not forgetting what you learned in previous weeks. Are you still looking happy and satisfied, begging for cum, do you have that look in your eyes? You need to improve that.
When it comes to cum eating, it's similiar to exercise. We need to cover it from every angle and every way, just like you exercise different muscles, so you can develop properly, into a proper cum whore.
You will cum in your mouth today, gargle it, spit it out in a glass, and then drink it. Let some of the cum drip on you as well. Oh, and if you were washing your teeth or something after cumming in your mouth before, that needs to stop now. You need to feel the taste of cum in your mouth.
