I regularly visit a local naturist beach, always hopeful of having some fun.

On this day, it was early in the season, and very quiet, I was the only one there.

Soon I was naked enjoying the sun, after a while two girls in their late twenties arrived, I'm in my sixties.

They walked past me and disappeared behind some rocks.

Eventually I had to go and have a look, peeking around the rocks I could see they were both naked, rubbing sun cream onto each other.

I couldn't help myself, and started wanking.

Suddenly someone behind me shouted "what are you doing" it was another girl and she was photographing me.

The other girls came running, they knew each other and were all really angry, threatening to take the photo's to the police.

I begged them not to.

Sue one of them said "well, I suppose we could punish you, what do you think, Lisa said what should we do, Kim said I've always wanted to try ballbusting"

My heart sank, as quickly as my cock, but what could I do.

So I'm stood there, Kim was really keen, she made me spread my legs, hands behind my head.

I'm thinking she won't kick too hard, how wrong I was.

Her leg swung forward, felt her leg connect, driving my balls up.

I collapsed in agony, looked up to see Kim standing over me with a smile on her face, she was loving it.

Kim said " who's next" Lisa said " me, I want to make him suffer"

I couldn't stand, so Kim and Sue helped my arms, holding my legs apart, I knew it was going to be bad.

Lisa was swinging her leg, drew it back, and wham, instant agony, the girls let me drop, I could hear them laughing, saying "do you think he can take another" Sue said"he has to, it's my turn, I've never done it " Kim said " I'll check his nuts, I've seen plenty in A&E"

They rolled me over and Kim started checking them, saying "They're pretty swollen, but he can take another"

The smile on Sue's face said it all.

They got me on all fours, Kim and Lisa at my shoulders, stopping me looking behind.

I could hear Sue moving on the sand, but didn't know when she would kick.

It was the hardest one, she really connected, driving my balls into my cock.

Kim said "that was to hard, I think you've busted them"

She knelt down checking them, rolling by battered balls in her hands, in spite of the pain I started to get hard.

Kim laughed and said " looks like you survived, you better wank, make sure they still work "

So there I am wanking with the three of them watching, I managed to cum.

Sue looking down at me said " looks like you enjoyed that, if you want more you know where to come"

In spite of the pain, I was already planning when I could go again, from the looks on their faces, they knew it.
