I was given the challenge of filling my jock with marshmallow fluff. I start off showing off the jock, and what is happening in the anticipation of the challenge. I take the first handfull of fluff and make sure that I pack it down into my jock so that I will have plenty of room for more. There's so much of it that it covers my cock. The next handful I use to cover my low-hanging balls. After a few tugs on them, and a bit more fluff, I stroke my cock and add in my own cream.

Ready for the next one
