You're my test subject for another research project

In this custom video, you're my test subject for another research project and this time I want to know how many licks it takes to make you cum... :) I like up and down your cock and balls over and over and over again until you are ready to spurt a nice big load for me and now your homework assignment is to go back and watch this video again counting every single lick and report back to me the total number of licks it took... :)
