Time Travel Fantasy

You have been transported back in time to the 1940's. You've always had a weakness for pin-up models of that time...but you didn't want to actually live in that era. You have a good life in 2015 & you'd like to get back there...but the only way to save your life is to resist ejaculating while being seduced & tempted by a 1940's siren. It's a test. Hold off for 20 minutes & you'll be transported back to your happy life. Fail & you'll be stuck in the 1940's. Do you have enough self control?
