Again, another scenario not for myself but for poppers out there.
Fill balloons with liquid latex. If they barely have any air in them the latex won't harden. Then you can play with them, make a small hole or pop them to cover yourself in the latex, which then dries and forms a partial latex bodysuit around yourself.
Another one that could work for either:
Get some
elbow length latex/medical/surgical gloves. Then get some rubber band just where the gloves end. Inflate the gloves, with the rubber band preventing the air from escaping, giving you "balloon glove hands" with your hands still inside and controlling the balloons. They you can basically touch and/or finger yourself with the balloon glove hands!
