I posted on a message board specifically for office ladies working in the Marunouchi business district saying, "There's a part-time job where you can get a high reward during your work break," and 11 office ladies actually showed up! It's irresistible to watch them slowly bring the vibrator to their crotch and insert it, even while saying they're embarrassed! Watching the vibrator piston in and out with squelching erotic sounds, you can't help but think, "This girl must be feeling so good~"
