You climb onto her dais, wondering silently, "Are aliens ticklish where humans are?" You feel like this would be a great way to find out. You crawl behind the glaring Yathi, who still hasn't said a word, then stroke your fingers down her duct taped lower arms, enjoying the sudden change in mood for Wura. Her muscled arms tense up in ticklish anticipation; her mouth trying to hold in the giggles that she knew would give away her secret, a secret that you already knew.
"What are you doing?" Wura demands, her mouth curling into an involuntary smile as your hands slide closer to her underarms. She must be pretty ticklish if she's already smiling from even the hint of tickling her.
"I just wanted to talk like civilized beings, but you wouldn't let me talk. So I thought this might help calm you down." As you speak, your hands continue their journey down Wura's arms, now teasing her exposed upper arms. "Unless you feel like it isn't necessary for me to continue?" You glare in return at the Yathi, figuring even an alien could figure out a sarcastic stare.
Never dropping her tough girl attitude, Wura growls, "I'll never talk. Let me out of he-hahahahahastopthat!" Your fingers have finally reached their destination, Wura's exposed armpits. You spider tickle them lightly, which is still enough to cause the ticklish Yathi to giggle and struggle in her restraints. Her giggles evolve into snickers and chuckles as you press into the flesh of her sensitive underarms, caressing her nerves with ticklish sensations. Wura seems to have dropped her earlier restraint, her beautiful laughter flows freely out of her mouth. You're actually enjoying the Yathi's laughter, not to mention her helplessness. You continue to tickle the defenseless Yathi silly, running your hands down her ribcage quickly, which causes a yelp from Wura, then run your hands back up to her underarms. This must be hard on her, you think, remembering what Erin told you about the Yathi, she was probably trained not to show weakness, and being tied up probably doesn't help that.
"Mercymercyhahahahahastop!" The poor Yathi manages to plead through her laughter. You recall that the Yathi determine ranks in their society through submission; whoever submits to another must obey that person without question.
"Mercy is sounding a bit better. Maybe now you're ready to talk?" You almost want her to keep fighting, you really enjoyed tickling her. Wura didn't respond to your question, instead using her energy to struggle against the duct tape once more. You feel like a little more tickling will finally break the Yathi. The question was, where?
