This video has two scenes. The first I start in a jockstrap (it doesn't stay on long), and get an amazing full jar of jam experience. In fact, it's so good that I finish within a couple minutes (yes, you just about get to see it). The second part starts off with me in a leotard and Lycra boxers on the next day. I use the rest of the jar of jam from the previous scene, and spend much longer enjoying it all; including filling up the leotard. Eventually I strip right off, and there's yet another satisfying end

Jam is such a satisfying and cheap messy substance!
