Yuyu-chan, who is weak to pressure, didn't seem to fully understand the remote vibrator. But when pressed against her pussy, she wiggled her hips, breathing heavily and letting out moans from the sensation. During the walk outside, she kept saying "It's embarrassing..." with a troubled look, yet her eyes pleaded "more," and her body seemed to crave what came next. Seeing her squatting and trembling, with vibrator sounds echoing from down there, got me incredibly excited too. I was rock hard, gripping the remote tightly. She seemed to enjoy it so much that her panties were soaked, making me want to promise to go for another walk together.
