Ashley invites Jennifer Dilber, the most popular girl in school, and her friends to her slumber party. Mary-Kate joins her sister and the other five girls with very few enthusiasm, but when a game of "Truth or Dare" starts she finds herself being the centre of attention…

Mary-Kate smiles shyly and looks around a bit.

Silence falls. All girls’ faces go serious. Mary-Kate’s eyes widen, and she understands one second too late that she has told something bad.

Mary-Kate suddenly realises and blushes deeply. Jennifer hides her face in her hands and starts a muffling cry. Ashley looks at her sister in deep disapproval.

Mary-Kate is speechless. Her position is getting worse and worse as seconds slip by.

She appears to be doing some quick thinking: is it better to have the whole school know you kissed the most popular girl’s boyfriend… or to let six angry girls know that you lied in a "Truth or Dare" game?

And what would the "Dare" be, then?

But Jennifer is not quite convinced yet. She wipes a tear from his eye and stands up. Mary-Kate stands up as well.

Her terrible fate dawns on Mary-Kate’s face. She is doomed.

Without further talking, Jennifer grabs a bewildered Mary-Kate and pulls her over to her. Still standing, she bends the girl and circles her waist with her left arm. Then she raises Mary-Kate’s sponge robes, revealing her skimp night shorts and pairing shirt. A dead silence falls as she swings her right arm over her head…

SMACK!

SPANK!

On and on it goes, up to the twelfth swat. Jennifer spanks in earnest, her eyes still watery and a resolute grin on her face. She is actually spanking away her own doubts about Brad down on Mary-Kate’s bottom.

When the first part is over, Jennifer lets up Mary-Kate and drags her unceremoniously over to Kirsten. The second girl in line makes Mary-Kate kneel down on the floor and then lays her over her knees. Rolling up her sleeve, she proceeds with the punishment.

SPANK! WHACK! CRACK!

Ashley watches preoccupied as her sister’s rump is severely smacked by well-built Kirsten. She is not triumphant or even determined as the other girls: she is probably wondering what to do when her turn comes.

CRACK! WHACK! WHAP!

When Kirsten’s twelve are delivered, Mary-Kate still has three more rounds to go: supported by Jennifer’s hands under her armpits, she crawls out of Kirsten’s lap an on to Stacy’s.

CRACK! WHACK! WHAP! WHACK! SPANK!

Her spanks are the hardest, apart from Jennifer’s, and the really wails away on the poor girl’s bottom. By now Mary-Kate is starting to cry a little bit. Next girl, next flurry of spanks. But this time there IS a difference…

As Mary-Kate is brought to Lacey’s lap, Jennifer signals her friend to wait before starting. Then she keels down over Mary-Kate’s body and works on her shorts…

And with that she lowers Mary-Kate’s shorts, exposing her panty-clad little butt. With a nod of her head she orders Lacey to start, and the girl swats down hard on Mary-Kate’s round, plump bottom…

SPANK! CRACK! WHACK!

Twelve more are gone, and it’s only two girls left… Mary-Kate’s ordeal continues as young Eleanor, the youngest child in the groups, spanks her bottom with all the strength she can muster.

CRACK! WHACK! SPANK!

By now Mary-Kate’s thighs have turned a rosy pink, and most likely her bottom is in the very same state. The Dare is almost over. There is one girl left, though…

And in one quick motion Jennifer throws Mary-Kate’s crying body over her sister’s lap… at the same time lowering the child’s white cotton panties, her last garment of protection over her already well-spanked bottom

A few more seconds pass. Silence is almost total. Ashley looks up at Jennifer, who raises her eyebrows and points at Mary-Kate’s nude ass. Ashley nods slowly. Then she raises a hand.

SMACK!!

The spank is the hardest yet delivered, and two more follow in rapid succession.

CRACK!! WHACK!!

Mary-Kate howls and tries to struggle free, but Ashley has got a tight hold on her waist. Her twin sister tries to protect her upturned rump with her hands, but Ashley grabs the small wrists and secures them firmly on Mary-Kate’s back.

SPANK!! SPANK!! WHACK!!

Blow after tremendous blow reaches Mary-Kate’s bottom, and her sister’s face grows more and more excited as her job continues.

SPANK!! WHACK!! CRACK!!

The spanking does not end at twelve swats, and although all other girls have counted no one even dares to stop Ashley: it is too great to watch.

SPANK!! CRACK!! CRACK!!

Ashley spanks her sister with all her might, printing the palm of her right end on her morbid skin over and over again. Mary-Kate’s bottom has turned a bright red, and the little girl is crying in full, when her twin sister finally stops and releases her grip on her.

Mary-Kate tries pitifully to stand up, but she can not. She just lays on the ground defeated, broken, massaging her blazing bottom with one hand and trying to cover her modesty with the other one. Before she even realises, Jennifer and Kirsten reach for her clothes and strip her completely naked.

They all walk away. Ashley throws one last look at her poor sister before leaving with the others. Mary-Kate does not move. She just lays there and cries her anger out.
