Be a nice guy and warn her

You feel the pressure building, anytime now you are going to shoot your wad.
"Holly, sweety....oOOo that's good. I'm gonna cum baby... OH man am I going to CUM!"

She takes your dick out of her mouth, pressing her thumb into a spot just below the head of your dick. "Wow... you are the first guy to warn me." She stands up, hand still on your throbing dick. For that you get a prize."

"What's that?" you ask expectantly.

"Well, now you get to fuck me... but not here. Tonight after everyone turns in, I will meet you by the lake. When you show up, you get to take my cherry,' now she kneels back down, eyeing your dick, 'and my virgin ass." She swallows your dick in one quick motion, pulls it out again looking up at you. "For now, let me finish this up and by the way........ I swallow." This is followed by her engulfing your dick to its base, again and again. You can't hold back anymore and let fly. When you are sucked dry Holly stands up again. Not a drop of cum remains on your dick. "Wow, you sure have alot of cum. Hope you have more for me later." and she turns and walks out the door leaving you standing against the wall with your limp dick hanging down.
