Of course not!

After what feels like an eternity of testiclular agony that you can only blame on yourself, you hear one of the girls proclaim, "They're getting really squishy, it won't be long now!".

It seems with how acquainted her feet have gotten with your sack, she can accurately feel their fragility.

And then, the kicks stop. Maybe they have realised the severity of rupturing a random strangers balls on the side of the street, and have reigned reigned themselves in.

As you struggle to focus your eyes through the haze of pain you see the initial girl, the one that challenged you initially, running up to you from a distance.

*POP*

The toe of her shoe strikes your left testicle, pulling it away from your body as it collapses into slush against her foot. You fall to the ground wailing, the pain to much for you to even manage to cover yourself as you hear the girls and the surrounding crowd all cheering the resounding pop heard from between your legs.

*POP*

This is then met by another cheer as a second girl walks up and stomps on your remaining testicle, crushing it into the ground until it bursts under her foot as if she were putting out a cigarette. Your dick, hard throughout most of the ordeal, lets out a distressed orgasm as your pain receptors and your fetish are at odds.

From there the crowd disperses, you pick up varying fragments of conversation saying with what good fun it was to watch or how sorry they feel for that poor guy, never able to have children again. They don't know that you will recover, but that doesn't offer you much solace as a girl bends down and takes your money, before leaving you there in the street.

After a while, with seemingly no one thinking to call an ambulance, you manage to pull yourself up and hobble back to your time machine. All in all, this was quite a successful trip... though you will probably do some less damaging time tourism in the coming days, to give your boys a chance to recover.
