Wanking Challenge Day5

DOUBLE-INSEMINATION! You've made it, today I, as your Jerk-Instructor, will get EVERYTHING out of you! And you can take my word for it! First of all, I'll give you instructions that will really get to grips with all the issues, you're so full of semen because of yesterday that you feel like you're going to burst. Today you need a bag cleanse and you need it urgently! It's getting dirty and sour and there's no stopping you and when it comes, you don't think you can believe your eyes... Surprise! Surprise! (please don't give anything away in the comments ;-) )
