I know no one wants to think about this, but hell its an interesting thought, so I ask this:
What are some sexual things you have not done yet, but want to do before you kick the bucket?
I will start with mine:
Despite this never happening...
1. I want to fuck my wife and her friends on the giant speakers at an ACDC concert, but since the original lead singer passed on, I will accept the current line up. But also I want to cum at said concert during the cannon part of "For those About to Rock."
2. Wing walk fuck. Instead of fucking while skydiving, I want to fuck my wife on the top wing of a biplane while mid air.
3. Fuck near an active volcano, close enough to feel the rumble and heat, but far enough to not be burned up.
4. Deep sea fuck, or finding an underwater cave big enough to have enough air for a quickie.
5. Get rich enough for a space x flight to fuck in space.
6. Fuck on top of a speeding semi truck on an open highway.
7. do Mr.and Mrs. Smith fight scene, but with paintballs and the after aggression sex.
8. Tarzan Sex.
9. Hot air balloon sex over a European city.
10. Fuck on a conveyor belt in a factory.
This one is purely fantasy, will never happen...
11. Fuck on a falling Nuke bomb. Slim Pickens style. (Dr. Strangelove reference.)
