HUNTC-159 - I want to escape... but it feels good... I want to do more... I chased after my shy stepsister and repeatedly tickled her, causing her to become extremely sensitive and experience repeated arousal. A perverted awakening!

I thought my shy stepsister wouldn't argue back, so I tickled her, and she reacted excessively. Buoyed by this, I relentlessly tickled her as she tried to escape, and she became extremely sensitive, to the point of drooling and becoming aroused! Furthermore, my stepsister became addicted to the pleasure of daily tickle 'development' and began requesting sexual contact and tickle torture herself! I never expected her to become such a pervert! I was prepared to cut ties, but I'm glad I tried it! Now I just have to pray my parents don't find out!
