"It's important to have tension," she explained. "I'll need to feel the tension. Squeeze my arm where you actually see the indentions in my flesh."
Once Fallon got the gist of things, Banks instructed him to do it, "Harder! Harder! Harder!"
"My wife is going to kill me!" the host said, but the 39-year-old model reassured him that "it's all acting."
But Fallon wasn't the only man to fall for Banks' charms this week. While visiting Bow Wow's "106 & Park," the model turned the heat on by locking lips with the 26-year-old rapper.
"You trying to do the remix?" she asked Bow Wow, alluding to a time when the two kissed in 2009.
Tyra then proceeded to kiss him on the mouth.
The "Fast and the Furios:Tokyo Drift" star later reminisced of the moment by posting a video on Instagram titled, "TYRA KISS MY LIPS TWICE."
