Assist Me In Enjoying My Evening

I need a self-bondage setup that ends with me coming. I also love having my testicles tied and pulled tight. My only issue is limited gear, but here’s what I have:

1. Ball gag
2. Blindfold
3. Roughly six feet of rope
4. Two cock rings (one larger than the second)
5. Two rubber bands
6. Lubricant
7. Kitchen items: plastic bags, ice/water, etc.
8. Belts I’d really appreciate a scenario suggestion. Thanks in advance!
