Cherry and Kay Kay walk into room Number Two of a Yangon karaoke bar, where a man waits alone for them on a brown leather sofa.
"Come on, girls. Sing, please," he says, as they flick the karaoke machine to a Myanmar folk song they hope he likes.
The scene may not be uncommon in many parts of Asia, but was until recently rare here in isolated Myanmar, where economic desperation is increasingly pushing young women into a sex trade that hides behind the facade of karaoke bars and massage parlours.
At the bars, known locally as KTVs for "karaoke television," young women in their late teens and early 20s entertain clients in private air-conditioned rooms furnished with sofas and karaoke equipment.
Waiters enter only when customers order food and drinks, or if the women ring a bell to alert the management that a client is getting out of hand.
Workers at KTVs say sex is not necessarily on offer, but they add that in the private rooms boundaries can be vague.
"It’s hard to control men in this kind of room," 22-year-old Kay Kay says.
"They are so wild when they get drunk. I need to hold both his hands to protect myself. Sometimes I need to ring the bell to call for help from the waiters," she says.
Customers vary from teenagers to adults. Sometimes they come with friends, occasionally even with family, to venues that blur the line between casual entertainment and brothels.
