Hello,
Isn't this a good thread? I would think that getting a partner to squeeze is a good way to introduce bb, much more likely than kicking or kneeing.
The pics are great (I especially like number 5). I find squeezing to be my favourite, most used bb and its much more satisfying than the kicking I have done recently. I can build up the pain/pleasure for my bf for as long as I like, and use my voice too so its a great all round experience for him. In the end though, there's nothing quite like having his smooth balls in my hand while they bunch up and pulse out their sperm
