Bear Creek

"We're going to Bear Creek, it's a secluded little swimming hole I used to go to when I was young. The water is clear and cold and there's a waterfall there year round."

"Should we bring our suits?" Allyson asks.

"No need," You reply with a grin.

You pile into the car. Elizabeth and Alex sharing the front seat because they are the smallest. You rev the engine and notice each girl blush as their clits vibrate.

"Just try to contain yourselves until we get there. I've got a surprise for one of you."

You drive off down the highway. Accelerating as fast as you can. The girls all trying to contain themselves as the stimulation mounts. When you reach 90 MPH someone bursts.
