Are we talking end of the world scenario? Or something less severe?!
If we're talking end of the world, i'd blow every penny I could scrape together to rent a mansion - stocked with 100s of varieties of beer, and a curvy brunette, like Jamie Young... and then slowly but surely go down on her until she couldn't physically orgasm again, a bit of light S&M - tied up and forced to orgasm repeatedly, then ashamedly, i'd love to give her multiple creampies.
The thought of just once not having to worry about STIs and such being able to experience someone "first hand" would be delicious.
Marvellous.
