Warn the girls you're gonna explode

There was no other choice. With Tammy's pressure against your dick and after the eventful day of seeing two naked attractive women for the first time, controlling your ejaculation was impossible. You either had to burst right then and there or beg for Johanna to stop. Of course the latter was the better alternative!

"S-stop the car or else I'm gonna cum!" You moan, the grip on either side of Tammy's bare hips growing tighter in an attempt to hold back.

Multiple gasps fill the car at your words, but none louder than the driver's. "Wh-what?! This is my mom's car, you better not make a mess!"

After that, the car comes to a sudden halt. You assume it's in response to your request, but Angelica's declaration to the right of you says otherwise. "Oh hey, WE'RE HERE!"

While the hyper active teen is focused on the fun-land outside, everyone else in the car has their eyes directed at you. Tammy yelps, a late reaction to your early warning you guess, and immediately hops off your lap, turning her head to the part of you that she's just been unintentionally grinding against the past few minutes.

You twist and squirm, your entire body straining hard to not make a humiliating mess in front of such a curious, large female audience. Your cock twitches and bounces in desperation for release; this is of course a bad sign, but eventually the calm follows the storm. Your erection slowly falls still and your breath slow down. A couple seconds later and you're back to your normal state for the most part.

Yet that doesn't change the fact that you just announced your near ejaculation in front of a full party of nerds. It only takes a few seconds of silence to pass for the situation to process. Once it does, everyone besides Tammy, you, and the always so dense Angelica burst out laughing.

Your face reddens even further as the giggling continues all around you; even the naked and tied up Rebecca is chuckling in the back! Oh how you wish you could just disappear right now. To think that just a few days ago, a majority of these female nerds would be far too shy to even approach you during school. Yet now here they are, enjoying themselves at your expense...not that you blame them anyhow. Anyone would gain confidence being clothed in front of a naked guy.

"Thisch ish too good!" Abi cackles from the front, wiping a tear from her eye and clutching her thin stomach. "You've alwaysh been worried you're not curvy enough for Sam to like you, Tammy, but you nearly made him schquirt without even trying just now...so you muscht have schome shex appeal!"

"D-don't tell him that I think that!" Tammy squeals with a blush, although you have a hard time feeling bad for her considering your own circumstances...wait a second. Did she smile a little bit after what Abigail told her?

Anyhow, the worst part of this situation is that you can't even block your erection from the many stares coming your way. You might have barely prevented disaster, but you're still dangerously close to the edge and even the slightest bit of pressure could send you right back over the edge. Thankfully the nerds calm down though, and Johanna is the first to speak up. "Okay, can we get going now? I seriously don't want him to dirty the car!"

Everyone besides the three naked people agree, and the next thing you know, you're on your way to Zonker's.
