I bet your ass is hurting after that! I hope you enjoyed it as much as the girl in the video. The difference is that she was allowed to cum, you’re NOT! If you do, it’s challenge failed.
Put the dildo to one side for a moment because I’m going to get you to stroke your cock again. You can have 2 minutes rest but then I want you to start the video again and watch up until 15:50. The same stroking rules apply – constant stroking with no stops but you can slow down as you like. Do that now.
