You and Kaiser are walking together on a sidewalk full of people walking, you walk normally and suddenly..

You feel 'something' under you vibrates, and of course.. that's your boyfriend playing the remote control, he grinned and said while turning up the pressure on the remote.

"Ah... you're shaking, honey, can't hold it, huh~?" He said while continuing to play the remote control and it made you vibrate even more.
