19 y.o. Asya – Upper body tickling for the first time

Young Asya is studying nearby, I have noticed often her in a grocery, and one day I spoke to her and invited to shooting. “Why not” – she said. Of course, she never tried that and weakly imagined the process.
Well, Asya is on the bench, her hands are fixed and she's comfortable. I start to tickle her tender armpits. She is very sensitive, and giggles from every touch. Then I turn on her tummy and sides, explore her weakest spots with my fingers. I tickle her sides, ribs, underarms, belly and navel. She laughs loudly. In the middle of the clip I put a ball gag in her mouth and continue to tickle. It was a long first time and she loved it.
In the next clip I'm going to tickle her feet.
