Honestly ... I'm going Scarlett... but it's literally the hardest decision I've had to make. I'd rather just have both of them tied up with their legs crossed so I can tickle both of their feet at the same time ... and their upper bodies too bc they'll be real close
Even better... I'd want to watch them tickle each other
Something about Margot Robbie makes me think she would be crazy ticklish. Like one of those girls that if you poke them in the ribs one time they jump through the ceiling.
It's a close call, but I'd pick Scarlett Johansson. She's just so cool as the Black Widow. If Margot Robbie were to offer to let me tickle her, though, I wouldn't turn down the opportunity.
