I was thinking of accidental shots.
No. 
Probably you are right.
I played tagball once and women got plastic torso armor to protect against that eventuality (men though, were still liable to catch a plastic ball into the nuts at 100mph).
Besides helmets, is armor used for paintball?
And yeah, finding porn that involves pain (sado or maso ) isn’t that difficult.
As for the OP, it sounds like a fantasy from someone who really likes hunting and sex. If it did happen, we can safely conclude that they weren’t willing.
If you have a problem with accidental water balloons to the breast, you have a problem.
I haven’t experienced current Nerf technology, but I have a hard time believing that it’s painful, either.
I thought we were talking paintball. That smarts, I understand.
Naive question: in porn movies involving pain, is it real or enacted? I honestly don’t know anything about porn or how it’s filmed.
I skipped right over water balloons, I was talking about Nerf guns. My son and his friends had Nerf guns, and the projectiles aren’t always entirely made of foam; on some the leading end is a kind of rubber stuff. (example). I wouldn’t want to take a Nerf shot to the chest. Boobs are tender, yanno?
I now have this vision of call girls being payed to dress up in Hollywood FX-grade yiff costumes and getting chased through the woods by horny “hunters”.
‘Yiff’? Do I really want to know?
Sometimes real, sometimes enacted. I’d say often it’s based on some pain but the hurtee exagerates it.
Sometimes though, it just has to be quite real. Unless you really can pierce the skin or insert a rod into your urethra comfortably.
“Yiff” is the furry (people who dress up as animals) term for sexual activity.
Look at me, all those hours spent on Cracked and 4chan have made me into an expert.
Lumpy, I have that vision too. All we need is investors.
