It's Tuesday and the Casper High Girls Track team meet is in fifteen minutes. I can already feel the stirring in my loins just thinking about it. Girls. Girls running, sweating, bending over and panting breathlessly are gonna be everywhere— including Sam, who just last week, I caught working herself silly over a picture of me on her phone without her knowing that I was sitting there invisible and jerking off to her. Oh man; do I hope that happens again! Only this time, I hope there'll be that one difference that makes a change in everything

Tuesday-all-girl-track-meets are the best. This is my fourth time witnessing the event. Only now, I think I'm a little braver at what I can do while watching these enticing female creatures working their bodies and becoming even more delicious for a man to tame. To dominate. I'm beginning to think I'm that kind of man.

Right now, I'm impatiently standing invisibly with my back pressed against a wall of lockers in the locker room. The girls are getting dressed, but I'm keeping my pants up for now. I'm waiting until I really see them in action: breasts bouncing tastefully as they run, long and short manes flowing in the breeze they create around their curvaceous figures, muscular and long slender legs slowing to a halt before they bend over to pant and gasp for air after a good hard run… Catching myself about to moan, I stop it short and then swallow hard. I need to stop thinking about what's to come and wait. I don't want to lose myself in here. Not without losing myself to Sam, and she's not even seeming to pleasure herself before she goes out there to run.

I know one thing: I'm already hard as stone. It's killing me not to unzip myself and let my erection spring free of my restraining jeans. But I don't trust myself. I want this to be perfect.

I sigh and then immediately internally curse myself over for making another noise. None of the ladies seem to notice, much to my fortune. They seem busy talking now; boring things spill out of their lips: Drama, what else? Paulina is talking about Katie the lesbian again but only to be a bitch and make her look bad in comparison to herself. I still don't know what makes me hard for her, despite my annoyance and disrespect for the kind of person she is. Maybe it's just her body. Maybe it's the shear fact that I WANT to shut her up with my dick. Make her use that mouth for something useful: for pleasuring someone she's mean to. It'll just be good 'ol fashioned Karma.

I shake my head, feeling so much annoyance now that my lust dims slightly. Good, I want only to re-ignite it for once we're out on the track… The longer I can hold back, the better, the more satisfying it will be when I cum, and the closer my feelings for Sam get by simply watching and thinking about her.

While thinking about my now dulling lust, my sister takes the cake when she comes happily walking around the corner with her hair pulled back in a ponytail. Agitation is becoming more and more apparent for me. Apart of me is…jealous?…for better lack of a word, and hoping that Jazz doesn't somehow ruin my speculations of Sam. That's weird to think, I know: getting jealous of your sister for any possible chance of ruining your advances on your crush. I'm honestly not really sure where to place the odd feeling. I feel…possessive…almost, of Sam. That she belongs to me. Maybe this is just what cock blocking feels like? I don't know. I almost don't hear the whistle that comes from the gym teacher and I snap out of my thoughts at once to listen.

"Alright, Ladies, your free time is over! Stop the chitty-chattying and get out there and run!"

Of course, my groin is beginning to fill with the welcoming heat with the knowledge that I will very soon be seeing the girls out there in all of their sweating, panting glory. So I get moving myself.

As we walk out of the locker room, I'm waiting to go last so as to not invisibly bump into any of the girls, watching this one sweet ass sway side to side in front of me. It's a girl I don't know, but I'm becoming acquainted with the sight of her body already. I feel my lips curl into a sly grin before I bite my lip and silently tell myself to keep cool. I think I'm becoming antsy and anticipating what's to come.

Once I see Sam, I jog up behind her as quietly as I can and choose to admire her own round ass, the way it's so perfectly shaped and almost as if made just for my hands to fit over… I can't touch her, but I sure can admire.

The girls are lining up on the track, beginning to stretch out. What the heck. I'll join them in stretching out too; need to prepare myself for releasing my urges a bit later, after all. I stand behind Sam and stretch my legs as she does hers, basically copying all of her moves so that her cute, perfectly-shaped butt rests directly in front of me the entire time.

Finally, the start whistle blows. I move over to sit at the start of the grass in front of the bleachers and am already fumbling to get my belt undone. I unbutton and unzip, freeing my hardening cock from my jeans and my boxers. I may not be as close to the girls as I am in the locker room, but today's main benefit is knowing the fact that the water fountain is hidden in between the bleachers both on my side and the other. All of them will need it. Once Sam stops and moves for the fountain, I'll get up and move right behind her. This thought quickly brings me to a full hard-on.

I purposefully avoid looking at Jazz. I know her by the little streak of red in my peripheral vision. The only thing my blue eyes are settled on at this time is Valerie's breasts and the way they bounce up and down, up and down, filling me with the idea to titty-fuck her. As I would cum, I would start trailing it from her forehead and down her body all the way to her pussy. Oh, she'd like that. My mind is saying things I'm not really consciously aware of. It's just the sight of her beautifully big boobs.

Okay, Fenton. Chillax a little, huh? You want SAM. S-A-M. Perfectly round butt to fit in your hands, tits to suck in your hungry hot mouth, voice to whisper and pant your name as you pound her pussy with your hard strong body…

There we go. I'm dripping precum. A thought occurs to me: I have no real, guaranteed way of knowing that Sam is a virgin. She and Tucker are my best friends, and we hang out practically every weekend. But what about after school when there are no track meets? Does she— Wait a second, you idiot! You just caught her last week pleasuring herself to YOU! Duh. I want to mentally slap myself for being so dumb.

NOW do you see what I mean when I say 'possessive'?

The thought of Sam with any other guy will set me over the edge— and I don't mean with pleasure. I mean with undeniable RAGE. Though I don't think I'd mind a bit of girl-on-girl concerning her with, say…Valerie. Now THAT is something that I'd welcome with open arms, I think.

I have to sigh a bit louder. I can afford to, now. I was getting myself hot and bothered a little too easily. I tense up with the sight of Paulina bending over. I scoot myself a bit to get a better angle. I see nothing but a big ass and a place for me to bury myself.Not her cunt. Her ass. The other hole… The one I overhear the jocks at the lunch table bluntly say out loud they prefer because it's tighter than a pussy.

I bite my tongue and think about what a hard-hearted bitch she is. But I think my lusty thoughts aren't completely insane: I also hear that anal-fucking can be a lot more painful at first for the girl. It'd sure teach Paulina a lesson.

All is well, though; Sam is coming up on her first lap, her own breasts bouncing and her short and silky raven hair flapping behind her in the wind. She slows and starts nearing towards me. I know where she's headed: the water fountain. I stand up and somewhat re-buckle my belt despite my free cock sticking out from under it. It's just so I don't have to manually hold my pants up for now.

Now my feet begin to move as I stalk the girl.

My cock is completely hard, ready, and dripping with precum, all as my body's way of saying, "it's time to make a baby". But as I promised myself a week ago, I won't cum in Sam. If anything, if she'll let me, I'll cum in her mouth. If I find that she's freaky and wants it, I'll cum in her ass. But if neither, I'll probably just cum over my hand to finish the job.

Focus! My mind and body come alive as Sam gets more ahead of me while I'd been lost in my processes, and I follow behind a little quicker.

We're now hidden, and guess what? I can't hold myself back any longer. But I'm not about to kill her and make her pass out from not allowing her to re-hydrate herself. After she finishes slurping up the water onto her puckered lips from the fountain, I unbuckle myself again and grab her waist with one hand while my other slips over her mouth with the thought that she might make a noise of being startled from my first touch. Turns out I'm right.

She doesn't seem to realize it's me. I lean my lips closer and turn my head so I can directly whisper in her ear, "Sam, it's me." She immediately freezes and then seems to actually relax in my hold.

"Danny, what the hell? What are you doing?" She sounds accusatory at first, but her second question is brought on with curiosity. I hesitate.

"What? Sam, I need…I just need."

"..What?—"

"I saw you the other day with my picture." I say after she barely finishes speaking.

I can feel the tension as the air around us goes still.

"You…saw…"

"Yep. I gotta say, it looked pretty damn amazing. Can't say I wasn't doing the same thing…" I can't even right now! My dick is slipping under her tight tank top to touch her skin and I feel Sam stiffen.

"D-Danny…" She stammers. Her voice sounds…strained, as if carrying something I don't quite understand. Is this Sam? I thought she'd be pissed!

I'm met with her slim figure pulling from my grasp and strongly whipping around to face me. She grasps my face and pulls my head forward to lock her luscious, plump, wet lips on my own; all I can do is stare widely, cross-eyed into her face as my entire body feels flushed with red-hot lava coursing through every vein and fiber of my whole self. I can't just kiss her. I'm feeling her body up, and down, and not being fully satisfied with where I'm placing my hands. How she even found my lips while I'm still invisible is an exciting mystery to me!

I can't believe what's happening! She wants me badly! My tongue dances with hers for dominance, and she's winning. My hands happily grope her butt which I've wanted to touch for so long. My dick is now wedged between the two of us and I can feel her abdomen sliding up and down against it, wanting it; oh I'm just dying with lust! I can't take it anymore.

I turn her back around and bend her over, moving my hands over her own and guiding them to grip the water fountain. I pull her shorts down and start grinding my cock between her thighs and under her black lace panties. Sam moans at what I'm doing. I can feel the moistening from under her increasingly heating pussy.

Now that I know for a fact that she's wet, I won't hold back the inevitable any longer. I merely part her underwear just enough and slip the head of my precum-leaking cock inside. Sam bites her lip with a low groan. My jaw opens at the surprise of intense heat and wetness I feel from her cunt. Another thought occurs to me.

"Sam?" I ask, breathlessly.

"Y-YeYeah?"

"Are you on…any birth control?"

"Yes..."

I sigh with rapture. I can cum inside Sam. I slip myself further in, about two inches if I have to guess. I feel a slight pressure at the tip. "How do you want me to break your hymen?" I ask, knowing that she's a virgin by my earlier thoughts, and now, by the fact that I can feel her barrier.

"Qu-Quick; please, Danny."

Like a band-aid. I think and thrust my full length inside of her sweet, juicy, and HOT pussy. "Mmm, so tight, Sam." I moan in her ear with my stomach now leaning over her back.

Her body gives a shudder underneath me. I remain inside her I don't know how long; I'm just savoring the feeling of the wet, warm, soft, tightness around my throbbing member. Sam seems to like me having her filled completely in the moment, too.

"GOD, DANNY— So big…I can feel it pulsing..ahh..hahh.." Sam moans and I realize her voice is getting a little too loud so I wrap one arm over her mouth. My other hand grasps her hip to hold her steady below.

I take a deep breath, beginning to slide my length slowly out of Sam's tight cunt, just until the head is nestled between her labia lips. I thrust myself into her with such force; I think it absolutely takes her breath away. She gasps out and starts grinding herself around me. I chuckle quietly and move my hand from her hip to her front and start toying with her clit. She arches her back up against my stomach and moans against my arm. This is enough for me to get going.

I begin my slow, rhythmic humping against her warm, taut butt, my hard cock parting her walls over and over and throbbing more with each stroke. My eyes shut at this wonderful feeling. I concentrate on the way she feels, memorizing every silk-lined ridge of flesh in her soaking, tight walls. I focus on the sound of the sopping wet suction of her pussy around my cock. My jaw is gaping open in disbelief at how good this feels.

"Ohh, god, yesssssaaaam..." I meld the two words together of my pleasure and I feel her shiver beneath me once more.

She squeaks into my arm and it makes me hump her wet cunt a little faster. We're breathing raggedly now, but remaining at a good volume for the other girls and the gym teacher to not hear us.

Suddenly, at one of my angled thrusts into her, Sam thrashes her body in my arms with a muffled shout. I'm not sure if I hurt her or not, so I hold myself still inside of her and move my arm slightly away from her mouth. I whisper in her ear, "You okay, Sam?" She nods. "You hit a sweet spot; please, PLEASE, keep going; don't stop!" I smile wickedly at her words and promise, "I will make your pussy milk my cock anytime you want me to; I'll fuck you at every track meet; you're mine." Sam moans back into my arm once I press it to her lips again, and I begin humping away at her butt.

God! She feels so damn TIGHT! I find that whimpers and grunts escape me as I drive my swollen man-meat into her very ready pussy. Each of my thrusts seems to hit her sweet spot, for she cries into my arm with pleasure and arches her back multiple times. I can feel her cunt gripping me and pulsating around my throbbing prick. I feel myself hitting the back of her, right up against her cervix and nearly into her womb. I feel her wet juices running down my cock along with my precum and slipping over my balls which slap wetly against her cute and strained round ass. My groin is tightening further. I'm close to cumming, but I want Sam to cum first.

"Feel this big cock, Sam. I'm so fucking horny for your body; take my cock...take it..." I whisper naughty things in her ear, and feel her body shaking with desire and pleasure around me. Her pussy tightens around my cock even more at just my words, making me grin widely with pride. "I want you to cream around my cock, Sam. I want you to feel every throb and pulse, feeling it stretching you and filling you to the brim. I want your pussy to flood my cock with your liquid lava, rippling around it and squeezing it to death. I want your pussy to milk my cock and drain me completely. I want you to realize that I'm pumping my baby-making seed into your body deeply and filling your womb so much that the excess gushes out of your cunt and onto my groin." My words are definitely getting to her. They're even getting to me. It's very hard to hold back; I have to slow down!

I pull myself out so that just the head of my cock rests in her cunt. I hear someone walking towards us and I spread my invisibility onto Sam and pull her with my arm still around her mouth away from the water fountain. I watch as my sister comes into view and heads for the fountain. I feel a little better now. I'm not as close as I was mere moments ago. Sam's pussy muscles even relax around the head of my shaft.

Jazz drinks, turns back around, and walks away. I wait until I stop hearing her footsteps before I sink into Sam again. She sighs blissfully into my arm and I move us back to the fountain. I start humping her nice and slow as I started out before, giving her more time to adjust and to accommodate my size.

"Mmm yes, Sam, take me. I'm close; please; you need to cum around me." I know it won't be long now. Her cunt feels like it's shuddering around my hard tool, and then suddenly grips it tight. It feels like the best massage and hug of my entire life.

"C-Cumminnngg..!" She mumbles into my arm, and I fuck my cock all the way up inside her slick, tight cunt. I gasp, her cunt muscles gripping me the hardest yet, pulling and sucking my dick inside of her and milking me hungrily. Her juices come rushing around my cock-head and gush around the rest of my length, the heat of her pussy intense and driving me insane! Her steaming juices come running out of her pussy and onto my groin, dripping down my balls and running along my thighs. I finally shudder with a burst of orgasmic bliss exploding inside me, forcefully pressing my crotch as hard as I possibly can against her wet, sweaty ass. The semen in my balls is rushing in lightning speed to my cock, spurting rope after thick, creamy rope into Sam's milking cunt, my seed going into her cervix and spraying her womb until it's full of my sperm. My cock twitches and jumps inside of her still throbbing pussy, and it seems to fire up another orgasm for her. Her body convulses around my grasp, moans and muffled cries vibrating into my arm, and her pussy sucks my cock inside her again and again.

I feel like I'm about to pass out with the way my eyes roll back in extreme pleasure, but somehow, I manage to stay upright and conscious.

Soon, it's over, and I imagine she's done seeing stars and fireworks just as I am. We pant heavily, and I slide myself all the way out of her. She's satisfied. So am I. I gently release her from my grasp and let us both fall on the visible plane. We're both drenched in sweat, among other things, as I fix my boxers over my softening cock as well as my jeans and buckle myself up again.

Sam looks at me with the most lovesick look I've ever seen, leans up to peck my lips, and adjusts her panties appropriately before pulling up her shorts. Her face is flushed deeply from exertion, as I can imagine my own face to be. We smile, still catching our breath.

"Danny..oh, that was amazing. And you're right—I can feel the excess outside of me..It's making a pool in my underwear." She gives me a sly grin. My eyes widen at her words.

A smirk crosses my lips. "We'll do it again real soon, Sam, I promise."

She nods and points back to the track. "Alright, I get it. Back to your little track meet. I should be headed home so that my sister will think I've been there all this time." I chuckle a bit.

Sam doesn't reply, but she winks at me and heads back out onto the track. I transform into my ghost half and take off towards home. I will never in my life forget this day. And to think, it will happen again at the girls' next track meet… I must be the luckiest guy in the world!
