Four girls writhe and contort their bodies in laughter, their faces twisted in agony, yet joyful giggles can be heard each time they cry out. Their voices, initially screaming "No way, seriously, I can't!!", have now transformed into sounds of pure ecstasy. Brought to you by Smile Lab, this is an endless, exhilarating journey into the pleasure and laughter of tickling!!
