Just 24 hours after setting the Sichuan Giant Panda Research Centre's record for panda sex by fucking his old flame Zhen Zhen for seven minutes and 45 seconds, Lu Lu the panda aka the "Enduring Brother" more than doubled his record sex time while doing it with another bear at the center. Sorry Zhen Zhen.

Lu Lu reportedly had sex with his new friend—Xi Mei—for a staggering 18 minutes and three seconds last week. For comparison’s sake, the average panda sex session lasts between 30 seconds and five minutes; another couple at the research center recently had sex for only one minutes and 20 seconds. Will Lu Lu's reign as the panda sex king ever end?
