Community of Sexsoundlovers

This was recorded a couple of years ago at one of my stays in China, where I go often and often hear sex performed. But unfortunately it's often difficult to record due to a lot of security cameras and security guards patrolling the corridors quite often - at least at the 4 and 5 star hotels, I stay in there. And another factor is the ventilation and/or air condition system which sometimes give a very bad sound quality.
But this time I managed to get this - I presume - youg couple. I didn't see them, but their lovemaking was pretty loud and the girl has some very nice moans and at around 6.35 on the recording the guy comes quite hard it sounds, so I hope you will enjoy - I sure did recording it!!

I wonder what they are saying in Chinese - this 'choaaa', they say a number of times - any Chinese here that can help??

Sorry - I had to split the file in 2, so the guy comes at 2.50 in the second part.
