"Let's have a competition to see who I should fuck."

You breathe deeply. sending an intense wave of pheromones over Hannah as she processes your words.

"Oh," she murmurs, "perhaps I can convince you that you don't need a competition to find that out..." she slips a hand over your shoulder.

You grin. "Don't worry, I know. You've already got a spot on the team."

Hannah purrs contentedly. "Oh, well in that case, if you really want I'm sure they'll be happy to agree."

As Emelia's team finally finishes their last length, the young instructor quietens the talkative group. "Well done everyone - but we still have thirty minutes, so we're not done yet. Boys - do the relay again."

As Hannah talks, and the grumbling boys wearily kick off, you push your pheromones as hard as you can. You can almost sense the chemicals diffusing through the water, finding their way into every pore in the teens' bodies. Finding their way deep into their pussies, absorbing into their razor-hard nipples.

"As for the girls - we have a special challenge today. A competition, to see who gets to be fucked by Michael."

There's a beat of silence. For an instant, you're plagued by doubts. But, to your relief, the pool suddenly erupts with excited gossiping, as every one of the fit female swimmers gazes hungrily at you.

"Isn't it obvious?" A haughty voice rises above the rest. You're not in the least surprised to trace it back to Sasha. "I know you want me." She speaks directly to you, her eyes never leaving yours, staring you down like a tigress. "I'm the hottest, most desirable girl in school. Why would he ever pick any of you?"

For a moment, the girls stand, stunned and anxious, not saying a word.

"Because I'll do this," says one of the girls suddenly - Harriet, a tall girl with straight brown hair. Her long fingers tuck under her shoulder straps, as she pulls down her swimsuit, revealing her small but perky breasts for the entire swim club to see.

"Harriet!" cries Sasha, outraged that a member of her circle would try to undercut her. The tall girl raises her eyebrows unapologetically.

"Me too!" cries another of the girls, revealing a bouncy pair of chocolate globes.

"And me!"

"I'll take mine all the way off!"

"No, look at my pussy!"

You grin as the dozen girls before you strip naked in the pool, posing erotically, desperately trying to sell you their bodies. Swim hats and goggles are torn off, releasing locks of damp hair into the water. Soon the only one not acting like a nude model is Sasha, who is merely staring at her 'friends' in disgust.

"You're all so pathetic," she suddenly proclaims, quietening even the few who have started rubbing themselves and moaning for you. "Most of you don't have so much of a clue how to be sexy," she continues contemptuously. "Even my girlfriends. Honestly."

She turns to Martha. "Too tall." Martha hisses as Sasha's varnished toenails dig into her ankle. "Too ugly." A black girl blinks as if she's been stabbed. "Too small." Sasha's ginger friend presses her hands to her breasts self-consciously. "As I said. Pathetic. There's only one girl here good enough for Michael, and it's obviously me."

Sasha begins to wade towards you, her swimsuit seeming to somehow fall off her body, revealing supple shoulders, round gleaming breasts, and a hairless pelvis, right down to her hypnotic pink nether lips.

"That's it, baby," she coos, wrapping an arm around your waist and pulling your erection right against her stomach. "You know it could only ever be me. Those ugly bitches never stood a chance. Now give me that big, thick prize right up my tight little pussy."
