jacking off so hard theres electric current

it started off slow when i opened the notification, but the second i saw whats happening, i immediately picked my pace up, with years of precision and skill, it didnt even slip my iron grip ONCE, the grip of my hand on my rod was so TIGHT its almost as tight as shins chocolate starfirsh. I shook it an exact 104 times, came 3 times (i usually last pretty long.) But i just cannot last long for this manhwa, in around 67-69 strokes, i saw something crackling on my crotch, i looked down shocked, but then i realized, its kinda tingly, and it felt amazing, so i just kept picking up the pace, and made sure before i busted i pointed it to shins panel. 10/10 will do it again.
