Destined for Dawn 2

“It didn’t work, Dawn. We have to do it again. You have to keep fucking me!”

It was well after midnight. Infomercials inhabited the unwatched television on the other side of the bedroom. Buffy laid on her side, her head cradled on the pillow, a dreamy smile on her face as Dawn ate out her asshole. Rimming it as diligently as a slave.

This was the one part of having sex with Buffy that Dawn didn’t like, even though licking her anus seemed to be what Buffy had arbitrarily decided was what should come before being fucked in the ass. Dawn topped her, Dawn sodomized her, but Buffy was too much of a damn brat not to top from the bottom.

“Eat my ass good, Dawnie!” Buffy thrust her hand between her legs, playing with her pussy as her sister’s tongue darted around in her rectum. “Gggnnhhh! That feels so nice! Keep eating my ass! Make me come! As soon as you do, you can fuck this tight Slayer ass!”

Actually, Dawn was so tired, the prospect of fucking Buffy didn’t appeal to her at all. After a long day at school, her new ‘bitch’ had given her a feverish round of cunnilingus as soon as she came back to the house. Dinner was the fastest she had ever eaten, with Buffy insatiably rubbing her thigh under the table. Dawn had managed to put her off a little by citing the need to do homework, but at six, Buffy had insisted that saving the world was more important. She was adamant that Willow would do Dawn’s homework for her. 

And from then until one in the morning, endless fuckings. Dawn’s body ached from all the things she had done. She didn’t know how she could have the strength to thrust into Buffy’s ass one more time. And getting fucked in the ass, being Dawn’s anal bitch, seemed to be Buffy’s new favorite thing in the world. 

“Fnnnh!” Buffy reached down to rub her clit and her hips started rocking, working her ass onto Dawn’s licking tongue and throbbing around its penetration. “I’m really close, Dawnie! Keep going—just a little more—oh shit! I’m coming! I’M COMING!”

Her asshole puckered rhythmically, flexing in and out obscenely around Dawn’s tongue. Buffy shuddered, satisfaction immense as her lust burst out of her in a series of spasms.

“Enough?” Dawn swallowed her excess saliva a little distastefully. “I’m really tired, Buff. I have a big test tomorrow.”

“No!” Giggling, Buffy patted her naked ass, the cheeks splayed, the asshole gaping open enough to hint at the target within. “Now comes your reward, sis. You get to fuck the Slayer’s ass.”

“Can’t I get my reward some other time?” Dawn whined. “Come on, Buffy, we’ve already done it ten times!”

“Then it’s my reward,” Buffy said, opening her buttocks with her hands. “My reward for stopping Glory, which I will do, once we’ve really fulfilled the prophecy. I mean, we need to stop Glory. And we can’t take any more chances. The more we do this before the next time I fight her, the better the odds that it’ll work. Come on, Dawnie. You can do my pussy too. Put it in there first, then fuck your strap-on into my ass. Just one more time? Please?”

Groaning in resignation, Dawn crawled up Buffy’s body until she was at her back, as if they were about to spoon, though nothing so restful would be what Buffy asked for. 

Dawn’s hands slid around Buffy’s body, taking hold of her well-sized breasts, cool and milky, like scoops of ice cream. Then Dawn pushed the strap-on she wore into Buffy’s sex. Buffy only let her take it off to wash it. She didn’t give orders, but she always looked so crestfallen when she pulled Dawn’s pants down to give her a blowjob (and more) and it wasn’t there.

“Ouuuuh!” Buffy moaned, feeling Dawn’s strap-on boring all the way into her cunt. “That’s good, sis!” She bucked her hips like she was coming from being rimmed all over again. “Fuck my pussy a little, get me going really hot! I’ll come so good when you put it in my ass. I’ll be the best anal bitch you’ve ever had!”

If Dawn had ever had an anal bitch, she wouldn’t have lied to Buffy in the first place. She found Buffy’s swollen nipples, pinching them hard as she wearily slammed her dildo into Buffy’s tight cunt. With Buffy responding, moaning, heat pouring off her aroused body, Dawn soon found herself getting turned on despite her tiredness. She looked down in some disbelief at the lips of Buffy’s pussy milking the hard strap-on. No wonder Spike was so obsessed with her.

“Harder, Dawnie! Get that dildo nice and lubed up—I’m more than wet enough for it!” Buffy squealed. “And when it’s dripping wet, you can shove it right up my ass!”

Dawn did as she was told, fucking Buffy’s pussy hard and fast as she could, until her sister was on the brink of orgasm. Dawn didn’t feel so far behind her. Buffy dug her fingernails into the shapely mounds of her buttocks, almost hard enough to break the skin, ensuring her cheeks would not be anything but wide apart as Dawn pushed the large dildo into her ass.

“Now! Fuck my asshole now!” Buffy screamed wantonly. “I’m ready! I need to be fucked!”

Dawn pulled out of her sex and obligingly pressed the strap-on into her pink little opening. Buffy gasped with immense pleasure, feeling the artificial cockhead going inside her. Making the walls of her anal passage spread and stretch to make room for the thick dildo.

“Feels so amazing! Shit, Dawn, if only you knew how great it was being your slut!” Buffy panted out. “Ram it all into my asshole, Dawn! Unnnn, gghhh! I love it! I love having you fucked me up the ass! We’re so going to beat Glory this time! Gonna beat her so hard!”

With half of the strap-on now buried in Buffy’s asshole, Dawn gasped in disbelief to see the muscles roiling through Buffy’s taut buttocks. She could only imagine how it felt to have all of Buffy’s rectum clenching and sucking at you. The insensate material of the dildo did nothing to enlighten her about the sensation. 

But she could squeeze Buffy’s pert breasts, her stiff nipples, enjoying their supple feel as she embedded inch after inch of her strap-on into the taboo heat of Buffy’s anal depths. A heat that was denied to Dawn’s senses, forbidden to her, unless she wanted to stick her fist and forearm up Buffy’s ass. Some days, it was tempting.

“Nnnnhhhhh!” Buffy groaned with lewd enjoyment, feeling her asshole suckling at every inch of Dawn’s strap-on. “I love it, Dawnie! You’re gonna get me off! Please make me come—fuck me hard—make me come in my ass like the goddamn anal slut I am!”

Buffy took her hands off her ass, letting her buttocks jiggle and jostle with Dawn’s thrusts. Instead, she clawed at the sheets, relieving the pressure of her clenching anal muscles in her own way.

“Fuck me, sis! Fuck my ass!” Her gasps and moans drowned out the lowered volume of the ignored television. 

Dawn gave in; she had to do to Buffy what she wanted. She pulled the big dildo out from between Buffy’s cheeks, sighing as she watched the pink ring of her anus shrink with more and more of the phallic shaft slipping out of it. Then she speared the whole thing back in again, spreading the walls of Buffy’s passage in one good thrust. From then on, she was reaming out her sister hard and fast, her groin smacking against Buffy’s juicy buttocks with every stroke.

“Harder!” Buffy mewled, shamelessly rubbing her own erect clit as she took Dawn’s strap-on. She could already feel the tumbling warmth of an orgasm about to hit her. “I love it, Dawn! Rrhhh! I love what a big fucking cock you use on me! Ruin me with it, wreck my asshole with your strap!”

Her anus loosened, seeming to melt around Dawn’s pistoning dildo, and Dawn took advantage of the new ease in her motions. She sped up, pounding deeper and faster between Buffy’s jiggling buttocks.

“Oh fuck—such a slut—getting off on—being a whore—your fucking whore—I’m coming!” Buffy keened. Her sphincter throbbed convulsively around Dawn’s strap-on, sucking at it with the same overwhelming force as the orgasm she felt. “Ggh!”

And Buffy rolled on top of Dawn, still being spooned by her, only now she lay spread-eagle on top of Dawn, sandwiching her little sister between her own flesh and the bed. She rubbed her clit hard and humped herself in a frenzy down into Dawn’s strap-on, making the mattress creak with the combination of their shifting weight.

“Fuck me! Fuck my asshole! Oh Dawnie! Unh! UNHH! YES! Oh God! I’m COMING!”

The fury of her climax pumped through all of her, filling her empty cunt with cream and forcing her anal muscles to be so tight around Dawn’s strap-on that it was impossible to move it. Dawn moaned, feeling like she’d been sucked against the burning heat of Buffy’s ass, feeling its feverish, orgasmic pleasure radiating right through the strap-on and into her cunt as Buffy came and came and came.

“Oh God… oh God…” Buffy panted. “I think I fucking squirted… you wanna try to do that again?”
