Time for swim club...

You gasp as your cock throbs in Cassy's mouth, making her cheeks bulge as she struggles to swallow gallons of your seed. Isobel and Emma squeal with delight, each of the beautiful girls draped over one of your shoulders, caressing your muscular body with their smooth, elegant arms. As Cassy slumps to the floor, humming ecstatically, eyelids fluttering, you smile to see Amy walking over.

"Hey baby," she winks. "Having fun?"

"Always," you grin back.

"Sooo," Amy snuggles into your lap. "I've been thinking about you. About the future."

You cock your head as you look at her, a little surprised. "Amy, beautiful, why are you worrying about that? I told you, I'm happy. With all of you, how could I not be?"

The redhead looks up at you, eyes sparkling excitedly. "Yes, but you deserve more. There's a whole world out there - school is just the beginning. And I know just where to start..."

As you change in the local leisure centre, you feel a tingle spreading across your skin like electricity. The smell of sweat and pheromones, the chorus of grunting and panting... it's all you can do not to go wild.

"Michael, get a move on! You're already two minutes late!"

Hannah, the assistant swim coach, jolts you out of your stupor. It's been a few weeks since you last attended your town's swim club, as you've been... occupied with other matters. You quickly tug on your shorts, and burst out of your stall, straight into Hannah. For a moment your chin bashes against her plump cushions, your washboard abs pressing against her taut midriff, before you part.

"Ohmygosh, I'm so sorry Michael," Hannah gushes, holding up her hands apologetically. She's twenty-five, and just out of medical school, working at the leisure centre for a while before she embraces her future as an endocrinologist. Normally a kid wouldn't know this much about his swim coach, but the thing with Hannah, was that every boy who had ever been to swim club had a crush on her. She was sweet, kind, and an absolute knockout, standing at 6'1" with chestnut curls down to her shoulder blades, a gorgeous heart-shaped face, and an hourglass body to kill for. Her legs were the stuff of legends.

"Oh - I see you've been..." she takes a deep breath, "...working out." You meet her hazel eyes, but she quickly averts her gaze. It seems while you were checking her out, she was doing the same to you.

After several seconds of silence, you suggest, "Shouldn't we..."

Hannah blinks. "Yes, of course. And hurry, they'll have started by now."

You speed-walk out of the changing rooms, and along to the main pool. You quickly join you peers swimming lengths. You might be imagining it, but you think you can taste your potential mates in the water, their bodies crying out for an alpha to take them. You know you have to be careful, though; the leisure centre isn't nearly as saturated with your pheromones as your school.

"Alright," beams Hannah to the group, gathered at the shallow end. "Mr Banks isn't well today, so it's just me, I'm afraid. Today we're going to be doing 4-man relays, with four 50m sets each. Get yourselves into teams, and please, without any drama for once? The gala is next weekend, so your performance today could decide whether or not you make the squad."

You absent-mindedly join a few of your mates in a lane, as you look over to the women's side of the pool. Amy catches your eye and bites her lip seductively, grinning maniacally. However, you're distracted as you overhear a rather intriguing exchange.

"...Sasha, I don't get it. We're friends - I know I'm not the best swimmer, but that doesn't matter, we're being assessed individually!"

A girl turns round to face the speaker, and you instantly recognise her. As both cheerleader and swimmer, Sasha is the most highly sought-after girl in your town, and probably the country. She wears a swimsuit that shows off her perfectly proportioned, porcelain body, not because it's streamlining (it's not), but because she knows it will get the coach's attention. She's reputed to be ruthless and cruel, but somehow every girl wants to be in her circle. Maybe it's because her dad's rich.

Sasha places a hand on the curve of her hip, twirling a stray blonde lock between her fingers. "Emilia, honey, I'm sure you understand. I only talk to you at school so you can do my homework for me. Even if we were friends, you wouldn't be in my swim team, because you're fat." You briefly take your eyes off Sasha's curves to look at Emilia. The comment was wildly unfair - by any normal standards, the girl - though fairly nerdy - has a perfectly fit body. But no-one quite measures up to Sasha's standards.

"Quit the fucking crying already," sneers Sasha, as Emilia turns away. "Ugh, she's such a baby," continues the blonde to her athletic teammates, who uncomfortably murmur their agreement.

You swim first for your team, and your newly improved strength and speed makes you amongst the fastest, despite your lack of practice recently. You glance over a couple of times to see Sasha considering you with a calculated gaze. As soon as you finish your sets, you jump out and pad around to where your young instructor is carefully watching the swimmers.

"Hey, Hannah," you say.

The brunette looks up with a start. "Michael!" Her cheeks colour, her pupils dilating.

"Listen, I've got an idea," you continue. Hannah gazes at you, the relay completely forgotten.
