Some animated gifs from Japaneses anime of boobs doing things that I’m pretty sure normal boobs can’t. But what do I know, I’m a gay man. 
Obviously this NSFW, no nudity, but weird boob behavior.
All of that looks extremely painful. Poor boobies 
As a straight guy, I wouldn’t wish those boobs on any woman.
Link is saying file not found.
Same here, link is dead. (I was trying to look purely for research purposes.)
I was afraid of that, here is a new link that shouldn’t go down.
No. Ow.
Clearly, the OP has never been to Suzy Wong Bar in Soi Cowboy in Bangkok.
However, back in the day I did know a well-endowed Texas stripper who could and would, to the tune of the Surfari’s “Wipe Out,” spin her breast tassles in opposite directions.
I did, of course, mean that to be plural possessive – “the Surfaris’ ‘Wipe Out’.” :o
“Won’t go down” is also the punch line of several marriage jokes.
OUCH. That looks like punishment akin to waterboarding.
How can those women stand up straight with breasts those large?
I’ve seen a video of a real woman with real breasts demonstrating various rotational movements.
I think a couple of those are from Eiken.
Presumable anime-humanity evolved with breasts largely filled with lightweight foam, or something of the sort…
Yowwch!
I’m thinking some type of gas, hopefully not explosive like hydrogen. Neon would be cool, as you could make them work like lamps.
The bottom 4 gifs represent the only times it is actually appropriate to say ‘calm your tits’.
The others are just odd.
Why would I want them waggling off in different directions? Besides, that much bounce inevitably leads to sag. The girls need some support if I don’t want them in my lap when I’m 50. I only let them out on special occasions.
Let me ask you this: would you guys want your balls to do that?
More tips in the G-string!
What makes you so sure they don’t already?
