You’re thinking WAY to pornographically.
Unless you arranged an orgy or just have * really * cool friends, you’re not gonna be taking loads back to back. Usually, it’s gonna be one at a time with a few minutes, if not a suitable amount of time between tops. IME as a top, the bottom is usually doing it DL style (dark room, blindfolded/mask, glory hole etc) sometimes in a cheap motel. They usually advertise on Sniffies or Grindr as a cumdump. Some will just give the address and room/apt number. Others want a face/🍆pic. Some will straight up send you the location.
From the cumdumps I’ve met or at least consensually seen their face and had a conversation with after, they’re usually average but rarely hot. Probably the hottest cumdump i met was a solid 7.5. About half of them were cheating on their SO, including Mr 7.5.
It’s exceedingly rare to get 20 loads in one night. 7-10 sure. But 20 is just impractical unless you love in a Top dense city. It’s the internet. People will lie for clout. Also i can guarantee the tops are not all models. It’s why cumdumps typically don’t discriminate. They care about getting some 🍆 and a load; then moving on.
That being said. Read this very fucking carefully:
Being a Cumdump comes with risk
* If it’s at your place and you’re doing Gloryhole/blindfold/darkroom, you may get robbed
* If it’s at your place, you may get stalkers/blackmail
* Not every guy is going to have the same intentions. They may unintentionally or even intentionally hurt you
* You can and more than likely will get an STI/D. Get on PrEP at the very least
* Go to the local free clinic afterwards. They will not judge
* It can mess with your self image
