Sian had a an awesome time tickling Redhead Michelle's upper body in the last clip - and we maintain that Michelle has the most ticklish upper body of any model we've had yet.

But Sian was paired with Michelle for a reason, which is that she herself cannot stand having her belly and armpits tickled, which at least means Michelle is able to even the score with her by visiting the same ticklish torment on Sian's soft pits and tummy, and she has Sian in total hysterics throughout this one!
