Tickled the sister in law again

So a while ago i posted a story about tickling my ex's twin sister. For all intensive purposes the same sister shall from hence forth be called the sister in law. Thats basically what she is and it is so much less confusing that way.

Anyway she had gotten home from work and I was watching all the kids. She invited her new boyfriend over and we all started talking. She walked over into the laundry room/bathroom(I know horrible design but hey). I got up from the couch and walked in and tickled her sides. She screamed and started to run away. Except she trapped herself in this very small room between the toilet and the bath tub. She stood there with her guard and i stood in attack. And i pounced and started tickling her sides again except this time much longer than initially. She started screaming and squirming trying to get away but she couldn't she feel to the floor trying to protect her sides. I tickled her armpits so she would raise guard there and make her drop guard on her sides. Then I tickled her sides again. I keep that up for about 15 seconds. Pretty short tickling but anytime i have to get her laughing ill take it because it doesnt happen very often.
Hope everyone enjoyed.

Very nice incident. Thanks for sharing your experience here.
