Lying on top of each other poseball for parachute jumps

Hey I hope anybody can help me.
I need a poseball (or I think it will be two) where an Avatar lie on top of each other.
The Avatars should have the possibility to turn right, left and so on (I want to make "tandem-jumps" with a parachute and so the "right and left arrow keys should be enable).
I have the equipment but no possibility to fall with a person who is hanging on my belly, so I think two poseballs (perhaps connect with a small invisible object) would be the best solution.
Perhaps anybody can say where I find such a poseball (with no sex animation

Your approach is sound. What you'll need to do is build a vehicle with gravity that just consists of the two poseballs. The actual building-with-prims part is easy, it's the scripts that'll be a trick. In short, forget about poseballs and look at freebie vehicles to hack.
