The video, which began circulating on social media over the weekend, shows the woman’s head buried between his legs, with the pair appearing to engage in oral sex in an open area.
The man, who is wearing a pink shirt but appears to be naked from the waist down, seems to notice the people filming them but was apparently unfazed by the attention.
The filmers of the video can be heard squealing and saying, “It’s crazy.”
One also asks if the man was happy while another tells him to look at the camera.
One onlooker quips that the incident proves that Hongkongers have nowhere to bang,
