Vertical Helicopter

When a girl is hung by her ankles to the ceiling, you spin her around, then the tension makes her spin while she sucks your dick.

A female Russian cosmonaut (with daddy issues) is preferable due to their high-g training. NASA doesn't spin their astronauts anymore so that won't work. If she throws up, bonus lube, and if she uses teeth, bonus religious conversion.

Katya came over last night and gave me a vertical helicopter. Now I'm Jewish.
