The orangutan inside appears to attempt to lovingly caress Kayley's belly through the glass.
"This was a wonderful experience however upsetting at the same time. He even had a tear run down his face," Bettany wrote.
Bettany's video was filmed in January, but went viral during the weekend.
The orangutan in the video was likely Rajang, a primate who previously rose to viral fame last year when he attempted to kiss a pregnant woman's belly through the glass of his enclosure.
