Cummings more than twice in a row

So i dont know why but i really want to know what it feels like to cum, and then just keep going until I cum again. Sadly, I get hit with a huge amount of post but clarity. Is there any way to not get as much post nut clarity, or any way i can cum twice in a row? Do i need to pause for a small bit? Do i just keep going? Please help me ✌️
