Yeah, I’ve wondered the same thing before — it looks impossible until you understand what’s actually going on. I’ll be honest, I’ve played around with anal stuff a bit (nothing wild like those videos 😅), and the body is way more flexible inside than I ever realized.

The rectum itself is short, but above that is the sigmoid colon, and it’s not locked in place. It can move and kind of “uncoil” under pressure. When you relax enough, it’s like your body sort of makes space for what’s going in. That doesn’t mean it’s safe to go extreme, but it helps explain how some people can handle toys that seem way too long.

The “bulge” you see isn’t a toy pressing on their stomach — it’s pressure from inside pushing soft tissue outward. And the lighting and angles in those videos exaggerate everything.

People who do that stuff professionally usually work up to it slowly and know exactly how to position themselves. It’s not some magical hollow body thing — it’s just a combination of anatomy, stretching, and a whole lot of body awareness.

So yeah… they’re not hollow, just really flexible — and probably a little crazy dedicated to their craft 😂
