Double PIV Sex

So, a big fantasy of mine, never experienced, but would love to......is double penetration in a woman's vagina. Was curious:

1.) Is it pleasurable for the woman?

2.) Pleasurable for both the men?

3.) What does it feel like for the two men rubbing their erect penises together inside of the woman's vagina?

Care to share your own actual experiences?

I've tried it with both my husband's penis and a toy and also with two toys. I didn't enjoy it, it was painful and felt unnatural. I've never given birth though as my kids are adopted so that might make a difference.
