Tickle domination by top giant Thalya and Vivi

Giantess Thalya and her petite slave with pigtails, Vivi are having some fun time in their bedroom. Thalya pushes Vivi on the bed to lay down, tie her legs and hands tight, then sit on her and start tickling her armpits and her side. Both of them really enjoy it at the beginning, then Vivi starts to suffer, she barely catches breath from a lot of ticking and she starts shouting while she is laughing hard at the same time.
