- Sure.
- ... Really? I won't have to obey anything anymore?
- Well, for now. If you behave. Tomo can help now.
- Yes sure... Help for what?
- We're gonna have a party tonight! There's gonna be Angie and Lucy.
- Oh great! But, with our parents too...?
- No what do you mean, they won't be home tonight.
- Huh? But... I'm pretty sure they're gonna be... Uh... I mean yeah, of course! Our parents are not here tonight! No supervision!
Arthur just recorded the fact that their parents weren't gonna be home tonight. Then he said to Zoey:
- Well, not exactly no supervision, we're gonna have a babysitter.
- Ugh, really? We don't need one, you can be my baby sitter... She said, taking Arthur's arm.
- Yeah, but our parents hired one. It's Ms. Colbert.
- What? The biology teacher who had a random attraction on you today? Isn't that bad?
- Well, they couldn't have known. And it's too late now, so we'll figure it out.
- 'cause I don't want people running at you like in the mall...
Of course she didn't. He had a last arrangement to make for the party to happen. He recorded in the dictaphone that Angie is certain to have been invited by Arthur to go to his house tonight, and that she will wear her nicest dress. She doesn't have to know about Lucy, and about the texts he send, impersonating Angie...
Anyway, they arrived finally at home and Tomo jumped off the bike.
- Phew! Too much activity for me. So can I have some special time with my boyfriend after all this effort...?
- What? Zoey intervened. No way! I need you... You need to go grocery shopping! We're having a party tonight for hum... Six people! And you're gonna cook too!
- Shit, do I really have too?
Arthur gave Tomo a stern look.
- Ugh... FINE! I'll do it! I'll better have a best girlfriend of the year award after that! I'll take this damn bike for the groceries, at least I won't have to carry you two!
And like that, Tomo left Arthur and Zoey at the door and went away.
- Wowh... Is she always that bitchy? Asked Zoey.
- Yeah... At least she has a great bod!
- Come on! She's not that... Oh, look, she left the clothes she bought for me! How about I take a shower, I change myself, and you tell me who has the best body?
- Sure.
- Oh my god, great! Thank you thank you thank you! We're gonna have so much fun! And, and...
- Don't overdo it please, you're still my sister, remember?
- Right, of course! Just... Fun between brother and sister!
And so Zoey went away, while Arthur went busy. He had some recordings to do. You see, he had a vision on how this whole day should end, and so he recorded very specific things into the dictaphone so that everything would go according to plan. What's his plan? We'll see it unfold as time goes on...
Anyway, Zoey came in a rather tantalizing outfit. From bottom to top, she had high heels with long white socks, pantyhose and a light-blue skirt, which was so small she wore a matching low-cut pair of shorts under it to make it less lewd. But it barely covered her butt, so Arthur a full view of her enlarge assets whenever she was turning around. Then, she had a small white blouse, bottom button removed to show her belly-button, and three buttons at the top removed to show an ample cleavage, and even a bit of her white lingerie bra. She even put on some glossy lipstick, eyeliner and makeup, and straightened her long dark hair that fell on her uncovered shoulders.
She was hot, and looked way older than she was. Arthur resisted the urge to cross his legs, even if he knew that Zoey couldn't see his bulge on his pants thanks to the dictaphone. He had to maintain the illusion that he didn't care at all about his sister, but it was a bit hard now. He paused, and she asked:
- So... How do I look?
- I... Hum... Yeah, it's okay...
- Come on, you froze when I entered! I can clearly see you like this.
- Yeah yeah, I have to say, it's good. Tomo made some great choices.
- I mean... It's a bit tight and small... And maybe a bit too sexy don't you think?
She said that, crossing her arms, and pressing her tits together.
- I... Yeah it is... I think it's inappropriate for young girls like you...
- So you don't like it? But you said it's okay!
- Yeah... Okay, of course you can keep this I don't mind.
- So... Can I sit on your lap again, big brother?
- S...Sure why not, you're my little sister after all.
And so she leaned forward, showing her big buttocks under her short skirt to her big brother. Tempting him by moving her thighs, shaking her butt cheeks... She even managed to move those cheeks individually!
"I think my butt is a lot more firm and muscular, after all this workout... Don't you think? Anyway, I'm soooo tired..."
Arthur said nothing, and let her finally sit. And immediately, as she was used to, Arthur felt his dick trapped in her butt crack. This time, she was indeed squeezing even more tightly. Even now that he was way bigger, in every way.
- Oooh, someone's happy to be with his sister!
- Don't know why you say that. Perfectly normal.
- Oh yeah? Then why do y... Do you... Ooooh...
- Why do I what?
- Nothing... Oh my... I really loooove sitting on your lap... It's so... Mmmmh...
Zoey closed her eyes, opened her mouth, and started moving back and forth. Which was normal, because of something he recorded. He made Zoey's butt extra sensitive, so much that just moving around on his dick would make her orgasm. He didn't want the only one to be embarrassed by the pleasure of Zoey's squeezing butt, and she was clearly enjoying it even more than he did. Even more having her moving around certainly felt good...
*plic* *plic*
He also liked the sight of erected nipples. So he recorded that every girl in the world has their nipples erected whenever they would feel aroused. And Zoey certainly was. And so her large nipples poked through her blouse.
- Mmmh... Aaaah...
- Zoey, what's going on with you?
- Ahah, s... Sorry... It's just... I feel a bit uncomfortable... Sorry if I move around, it's just that I... Ooooh...
- Well, might as well check your breasts while we're at it, uh?
- Wh... What?
Another thing that Arthur recorded, is that brothers now and then has to check their sisters' breasts, when they've grown. They have to squeeze and massage them to check if there's anything wrong with them. This was deemed as perfectly normal and not sexual. But not so for Zoey, who also had the sensitivity of her tits turned up ten fold.
- Are you su... Sure... It's... A good time?
- Sure why not, let me just remove that blouse...
And so Arthur removed every button of Zoey's new blouse, who turned red as a tomato. He then removed her bra... That was a nice bra too! But Zoey immediately hid her chest with her bare arms.
- Come on Zoey, you know I have to check them!
- But... It's... Embarrassing!
- No it's not, it's just breasts! Let me see...
She shyly let her tear shaped tits down, and Arthur began fondling them. Hmm... So soft, squishy and mushy...! Yet her skin was hard around her areola...
- Zoey, why your nipples so hard?
- I... I don't know... Must be the cold...
- Are you sure?
- Well y... Your hands are a bit cold...
- Oh really, you want me to stop then?
- N... No... Keep going... You have to ch... eck them... Hmmmm...
- Oh now you want me to? Well let's check them then.
And so Arthur kept squeezing Zoey's tits, pressing them against each other, lifting them, pressing them, moving them in every direction, and also played around her nippples. She was getting really hot, and all of this contact was really making her close to climaxing. Her panties were already drenched, and Arthur could feel his pants getting wet by just her juices. And she kept moving her butt back and forth, squeezing him with all the new strength she got... Arthur felt the blood rushing to his face too.
- Zoey... S... Stop moving so damn much!
- S... Sorry... I just can't help it... Aaaah... Oooooh...
- And stop... Making those noises!
- Yeah... S... Sorry...
- And stop apologizing! We... are... Just having a nice brother and sister moment...
- Ooooh, yeah... I love being your little sister... So much... Such... A nice... AAAAAAAH.... Ggh...
Her hands were clenching on the side of the chair. Her breasts seems hardening, even enlarging a bit under Arthur's pleasurable hands, and his massive member right between her huge butt felt so damn good... She was close to the edge, and so was Arthur.
"Arthur.. I... I... AAAAAAAAAAAAAAAAH!"
"Hey, I'm home!"
It was Tomo. She arrived with the groceries, just when both of them were having an orgasm and creaming their pants. But she mainly noticed Zoey, half-naked, screaming in ecstasy while just sitting on her brothers lap, like all sisters do, and having a breast exam by her brother, like all brothers do. Clearly, something was wrong with Zoey.
"What the fuck is going on in here?! Does this bitch just had an orgasm for no reason?"
Zoey's mind was blank, so it took her a few seconds to come back to earth, realize Tomo was here, and put back her underwear and her blouse in shame.
- S... Sorry Arthur, Tomo! I... I don't know what happened, I...
- Bitch, what the hell, seriously?
- I... I'm gonna go to my room, I...
And just like that, she ran away.
Tomo turned to Arthur:
- Seriously, what's wrong with your sister?
- I don't know, but get ready, because we have a party coming up.
