Right where he said he would - in her ass.

"Oh - Oh God, I...I..." Nat is panting too hard, and too foggy-headed from the pounding she's taking in her cunt, to get words of protest out. She just puts down her head and takes it, overwhelmed. {if Sluttery < 20}I...I can't argue with him, that would be...social suicide...{elseif Sluttery < 40}What's getting fucked in...one more hole, anyway?{else}Like the slut I am. God, I...I want it. I want it up my ass!{endif} She gasps as something cold and slippery suddenly lands on her puckered asshole, making her jump - the sensation is startling even in the wet, slick environment of the shower. {if Sluttery < 30}Is...is that lube??{elseif Sluttery <60}Lube...thank God, that's something anyway...{else}Fuck yes, he meant it...he's really gonna do it...!{endif}

Suddenly the boy's cock slips from her cunt, and Nat {if Sluttery < 40}gasps{else}moans pitifully{endif} at the sudden emptiness. She can feel him rubbing his fingers over her asshole, spreading the lube around, and then they're abruptly replaced by what is unmistakably his cock: hard and thick and hot. He rubs up and down across her asshole, grinding on her as he coats his cock in lube. As she tries to raise her head, he forcefully pushes it down again. "Get ready, bitch," he says roughly. "I'm going to enjoy this."

"{if Sluttery < 40}Oh, please be gentleooooOOOOH!{else}Fuck, me toooooOOOOH!{endif}" Nat's words end in a gasping groan as the boy's dick pushes against her tight hole and slowly, inexorably, forces its slippery way in. She presses her forehead to the slick tiles below her as he grips her waist and continues his intrusion, her body starting to shake with the sensation of his cock working its way into her ass. She breathes {if Sluttery > 40}steadily{else}raggedly{endif} as she tries to work her way through the feeling, the incredibly intense sensation of him entering her ass. It seems to last hours. Finally she hears the boy gasp as his hips touch her rear.

"Fuck, you're tight. What a good slut," he groans.

{if Sluttery > 60}"Thank you, sir," Nat whimpers. "Thank you for fucking my ass!"{elseif Sluttery > 40}"Ooooh...th-thank you..." Nat whimpers, overwhelmed.{elseif Sluttery > 20}"Ahh! Th-thank you!" Nat gasps.{else}Nat can only whimper in reply, too overwhelmed to do otherwise.{endif} For a moment, he's still, just filling her ass. Then Natalie gasps as he pulls back and thrusts slowly, firmly forward. "Oooh!" He thrusts again, more quickly. And again. And again. And he's fucking her ass.

Nat keeps her head pressed to the tiles as the boy fucks her, his strong hands gripping her waist tightly to prevent her from moving too much. Her mouth hangs slack-jawed and she can hear little shrieks escaping in time with the overpowering sensation of his dick sliding in and out of her lubricated anus. {if Sluttery > 60}It's been a while since someone fucked her ass. God, I've missed it.{else}This sensation is startling in both its novelty and its scale.{endif} She feels tiny and powerless. Like a bug. Like a toy for him.

"Haha, look at that girl," she hears a female voice giggle nearby. "A green-band buttslut? What a whore!"

"Totally," another girl agrees. "Wouldn't catch me getting my ass fucked in a public shower. I - ah!" She interrupts herself with a yelp as she responds to what sounds suspiciously like a firm slap on the ass.

"You'd get on your knees, though, right?" a male voice asks. "Because watching that slut get reamed has given me a major boner, and I'm thinkin' your mouth's a good place for it, Susie."

"Uhhh. I m-mean...sure, yeah...I guess I could...ooh!"

"Thaaat's a good girl," the male voice says, and then Nat hears a ****, spluttering sound. "You just open your mouth wide, I'll do the work." A wet, rhythmic squelching sound begins, and the boy calls, "Hey Hideki, who is that girl you're fucking?"

"I dunno." Nat yelps as the boy behind her grabs her by the hair, pulling her head up and sending electrical sparks of pain through her scalp. He doesn't stop fucking her ass. "Hey slut, what's your name?"

"Ah! Ah! Ah! I...I'm {if Sluttery > 60}just a slut called {endif}Natalie{if Sluttery > 40}, sir{endif}!" Nat gasps.

"Natalie," the boy - Hideki, apparently - calls back to the other. He releases Natalie's hair and she collapses to the tiles again.

"Her ass any good?"

"Yeah, it's - mmph! - pretty tight."

"Nice," the other boy laughs. "New school, new you, huh, Hideki? Finally you get some, and you go the whole way on day one!" He chortles, and Nat feels Hideki's fingers tighten on her waist, almost hard enough to bruise.

"Fuck you," he mutters, far too quietly for the other boy to hear. Nat shrieks as he begins fucking her harder than ever, savagely thrusting into her ass. She can feel him swelling, hear him snarling behind her as he brutalizes her, and then - suddenly he lets out a growl and she feels his cock twitch in her and explode, gushing out thick, hot fluid into her anus. Natalie gasps, quivering, at the {if Sluttery < 20}new {endif}sensation. Warmth spreads through her body in waves, pulsing out from her sore rectum. God...that was...{if Sluttery < 20}so intense...I can't believe I did that...{else}so...good...{endif} She feels Hideki pull back from her, leaving her gaping and empty.

"You're not bad at all. And obedient enough," Hideki mutters. "Natalie, right?"

"Uuuunh. Y-yeah?" Still cum-drunk on the floor, Natalie turns her head sluggishly to look up at him. He's standing by her head, gazing down at her with an unreadable expression. His now-flaccid cock hangs thickly between his legs, shining with cum, lube, and water. I should get up...clean that off...{if Sluttery < 40}it's only polite...{else}I want to...{endif}

Hideki nods. "I like your ass. I'll fuck you again sometime. See you around." Natalie can only groan her compliance as he walks away to finish his shower.

It takes her several minutes to gather the strength to clamber to her feet. When she finally does, making her way slowly to a shower, her ass is sore but her body is buzzing with the satisfaction of having taken that boy's cum. She takes a deep breath, trying to gather her wits, and starts to shower in earnest.

No one else bothers her, to her relief. Not that stuff isn’t happening; it’s just that it’s the end of the school day, and people are eager to leave. Still, there’s a fair amount of fucking going on, and the girl who’d laughed at her - Susie - is getting her face painted with cum a few feet away. As the boy who'd taunted Hideki finishes his climax and walks away, whistling, Susie's friend moves in. Apparently giving into temptation, she kneels beside the trembling, red-faced girl and begins to eagerly lick the cum off her face, stroking Susie and murmuring into her ear the whole time.

Soon enough, Nat's done with her own shower and her head is starting to clear. She heads out at the end of the pack, hurrying to get her clothes on and catch the bus.
