Nikki Brooks is ready to test the ticklishness of Sofia Rivera's armpits. Poor Sofia laughs just answering questions about how ticklish they are. Nikki give Sofia the first test by sandwiching her fingers in Sofia's armpits and seeing how long she can take it. Then Nikki instructs Sofia to hold her arms above her head and keep them there as long as she can while Nikki tickles her armpits relentlessly. (Interested in commissioning a custom clip?
