More helpful than you were thinking

You look over at Jenny, she appears to be enjoying the show. Her hand is below the water and her arm is moving in a way that suggests a little bit of self pleasure is going on below the surface.

"Jenny, help me out here and shut her up." As I say this Hallie lets out another loud moan.

"I think I know just what to do Mr. Dan." Jenny smiles and walks up the steps towards Hallie's head. As Jenny climbs the steps and rises up out of the water I see that she took off her swimsuit bottoms at some point. Her tight teenage ass looks amazing as the pool water drips off of it. She's skinny enough that I can see a hint of her smooth wet pussy lips from between her legs.

I had thought that Jenny was going to just place a hand over Hallie's mouth. Or maybe if I was lucky make out with her, but it quickly becomes apparent that Jenny has a more exciting plan in mind. She turns and sits in front of Hallie and then slowly raises her young pussy up toward her friends open and moaning mouth. Jenny's pussy lips are smooth and pale pink. She has a patch of very light blond hair that is almost invisible wet. Hallie lets out another loud moan as I step up my pace excited by the scene unfolding before me. Jenny, trying to be a good girl shuts Hallie up, she grabs the back of Hallie's head as she begins to moan, and pulls Hallie's face into her waiting cunt. The sound of the moans is immediately muffled.

No longer afraid of the sounds coming out of Hallie I start to really hammer her tight cunt. I'm able to continue on like this for awhile alternating between watching Hallie's butt jiggle as I slam into it over and over again, and watching the looks of bliss cross Jenny's face as her friend eats out her young twat. Soon I have another problem though as Jenny starts to approach an orgasm and begins her own series of louder and louder moans. Just then I feel Hallie's whole body go limp as her vagina spasms around my cock. Hallie now appears to be ****, Jenny is upset .

"Bitch, not now wake up! I'm almost there!" Jenny grabs Hallie's head and starts trusting her crotch into her friends face trying desperately to get off. "Oh fuck! Oh fuck, I was so close!"

She's really starting to make a racket, and I haven't even cum yet. What to do?
