The animal handler was posing innocently with the primate in front of tourists at Safari World Park in Bangkok, Thailand.
However, after slipping his left arm around the woman's waist, the furry fiend then raised his right hand for a quick grope.
The unabashed beast then began laughing as he carried on grabbing the woman's left boob in front of shocked tourists.
Zoo worker Sunan, 26, let out a nervous giggle as the amorous ape – named 'Ning Ning' – brazenly fondled her.
On the hilarious video clip, one onlooker is heard shouting in the background ''he's massaging it, he's massaging it''.
Safari park worker Khun Fah, who recorded the clip, said: ''Ning Nong is very cute."
"I think he knew what he was doing so that he could make people laugh.
"We told him off after and said don't do it again.''
