Vibro buttplug at shoping center

i experienced my vibro buttplug sex toy at home many time ,when you walk with it in your butt it's a great feeling , i decide to go at the shoping center with it ,i place it at home and i'm driving to mart . just before entering I took a few sniffs of popper, I already felt the precum wet my underwear I was very excited to do that in public. once inside, I activated the vibration control and the different speeds that I had in my hand in the pocket of my pants, when it started to vibrate a lot and by cycle like waves that always come back, it was very difficult not to moan in front of all the people around me, I wondered if the neighbors could hear the little noise of the toy doing its job because I felt like I heard it. As I walked I changed the speed and strength of the vibration every 20 seconds or so, a few times I had to take deep breaths to manage the pleasure I felt, I walked with my eyes almost closed at times so it was good. Then I wanted to stop it for a while as my breathing was starting to be long and deep. I couldn't stop it, the battery of the control was dead, I tried several times to stop it but it was impossible, I wanted to sit on a bench but it was still, the butt plug went in even more deep and the feeling was even stronger, my benchmate looked at me strangely, I think he thought I was having trouble breathing, he asked me if I was okay, I answered him yes but I had to catch my breath and the vibrations which never stopped, I was afraid that he would hear the little noise of my toy. I asked him the way to the toilets, so that I could manually stop it because I couldn't continue or I was going to fill my underwear with my hot load, I quickly walked towards the toilet and closed the door of the small cabin, I already had a big erection, quickly lowered my pants to reach the control button to stop it, I was almost at the beginning of ejaculating when I managed to stop it with my finger. I tried to remove it but it was too difficult and too sensitive while standing. I waited a bit to become a little soft again before leaving the cabin, I returned to my car to go home but I I felt like ejaculating too much, I parked further in the parking lot and I started to masturbate in my car, I turned on the vibration again and I masturbated even faster and more loudly, after about 3 minutes I ejaculated in my right hand and on the steering wheel too, it was so good I moaned very loudly, luckily no one was going back to their car near me. With my left hand I stopped the vibration I couldn't take it anymore. I went home to remove the sex toys, changed the control battery, plugged in the toy and took a shower. I will most likely start again soon because it was too good and too exciting.
