Good boy, I know it doesn't look like much, but trust me. It won't take much to get you squirming...
Start my wrapping yourself up nicely with a rubber band around both your cock and balls. Once you're bound and bulging, stretch a rubber band in front of your cock and slide your cock through it. Slide the band up and down while it's pulled as tight as you can. Enjoy the tight dry rubber grinding across your cock as you give me 30 full rubbery strokes of the band.
