An exciting hour of being her thong! Tiny Brother VS Big Sister chapter 20 by copier · original author: nearwhites

She took you out of her colossal butt, and put you in the bed, right in front of her face.

''You know Allen? I think you have to rest, we 'll go eat breakfast and then we will have fun honey'' She gave you a kiss, and then stepped up of the bed, you saw her huge rump covered by a white thong that were actually wedged between her ginormous cheeks, she took it out of her crack and only a pair of steps after that, the thong was again in wedged in her crack.

You couldn't help but laugh at this, however, when you started to laugh she saw you over her shoulder and giving you a flirty look, she took her thong and took it out

''You're next'' she says

''What?!'' You scream scared

''Nothing!, come on Allen, let's eat''

She and you took a healthy breakfast, during it you couldn't help but state at her boobs, but she didn't noticed this.

After her and you ended the breakfast, she took you to the couch in the living room and talked to you:

''Now that we ate, we can have some fun together''

''Wh...What kind of fun?'' You say looking upwards

''Wait in here, I'll be back in a moment'' Immediately after she says this, she walks towards her room.

You really thought about to escape, but if she catches you doing it, it would be even worst.

''I'm baaaack'' She came back with a red string in her hand and without panties, letting you stare at her pussy.

''What is that?'' You asked curious about how would that bring you both fun.

She stepped in front of you, and put the red string around her hips.

''You see Allen... this a thong that I made just for us!''

She turned around, revealing that in the rear, the two strings that goes around her hips and the one from behind weren't connected...

''For... For us? What are you talking about?''

''Allen, I've always had this problem with my panties and swimsuits, they wedge up my crack, aside from the fact that it is uncomfortable, it just looks like if my butt was bare you know?''

''Aunt, I think that I don't understand what you are saying'' You say scared as he'll

''What I'm saying Allen, is that you are going to be my thong, your work is going to avoid the wedgies in my ass''

''But aunt! How Am I supposed to do that?!, I mean, your whole crack is thousands of times bigger than me!''

''Are you calling me a fat ass!? You better start to apologise Allen'' she started to descend her bare goddess derriere towards you, you prepared to be crushed but instead her ass descended a few inches from you, you took a second to contemplate it in all its glory, it was just huge.

''Now Allen, kiss my ass''

''What?!'' You said almost dismaying

''That, kiss my ass or I won't forgive you''

You walked towards your aunt's gigantic ass, and put your lips in her left cheek

''That way is better, now, climb''

You didn't even asked about it because of fear, so you started to climb her cheek, your tiny hands made her tickle and laugh, and in consequence, jiggle her butt. After almost half and hour climbing, you finally stepped above her ass.

''Take this'' She gave you a string which you took with the left hand, and then another one that you took with the right hand.

''Grab them tight!'' She stepped up, and the pressure wasn't as bad as you thought, then she reminded you...



''There's one string left'' She took the last string and stick it to your feet.

The pressure above you was suddenly increased by a difference of two planet sized cheeks, the only good thing in that moment, was that your head was right above her crack, and your body was still out of it, but you thought that this wouldn't last much longer.

You aunt stepped in front of the mirror of her room and saw you in her butt.

''Wow Allen, you look very nice in there!, it's almost like if you were made to be in there...''

''Please, don't do this to me!'' You scream to her almost crying.

''Oh Allen, don't see this as a punishment, think of it as a favor from you to me!''

She started to walk towards the bathroom, and in the process, her humongous butt cheeks made their work.
Her flesh started to jiggle with every step, separating a little bit. Your legs were completely vored by her butt crack in just a pair of steps. By the time that she entered the bathroom, the only thing that was outside of her hell cave, was your arms and head. When your head was about to be eaten by her ass, she stopped, giving you a little break.
She was now staring at herself in the bathroom mirror

''Really Allen? Couldn't you hold on for just a few minutes at least, you're already giving me wedgies!'' She said kind of angry.

''But-

''Even though, your head looks like a good adorn in there'' She change her look and now looks happy. ''Well, try to not get shoved in deeper, or I will have to punish you''

She then walked out of the bathroom, with every step, her cheeks hits your head, merciless. She was about to sit when she realize that your head was already inside her colossal crack.

She then decides to...
