Masha, You won’t be able to rest well – Tickling in pajamas

By request
When Masha had dressed her favorite pajamas and went to bed, someone crept up to her bare feet and began to tickle. Masha laughed thru a dream. 
Hmm … I guess she thinks it's a dream…
A moment later, someone sneaks up to her and grabs her face … 
Damn!
Masha is kneeling on the bed bound in her legs and arms, like hogtie.  Her toes are tightly bound, arms are tied to the legs, elbows are tied too. Unknown begins to tickle her belly and ribs. Masha is ticklish, she squeals and laughs.
When will end this nightmare? He will tickle me to death!!! – she thinks.
Unknown does not weaken his grip, he tickles her even more, her feet and ribs. After a few minutes he puts a ball gag in her mouth, to avoid the noise. He is taken back to tickle her young body. Masha jerks and waiting for the end of this torture. Although sometimes it was even pleasant for her. The criminal lies down closer to her feet and starts to tickle her soles and between toes.
Well, now I can finish it…
