Yes

You finaly decided to tell her about your plans with Tania.

"Uhm.. Sophie sorry but today is a really special day."

"A really special day to which I, your sister, is not part of ?" She asks in a calm tone

"Not like that... It's just... There is something I really wanted to do and I can't allow myself to wait again... it would be weird if you had to come and participate" Sophie could feel your pleading tone. you rarely sounded like that so she knew you must be really wanting to do something today.

"So... What is it ? What's so weird that I can't even come to your place ? You're not committing a crime are you ?"

You pause for a second realising how suspicious you must have sounded through the phone and rolled your eyes before answering "Ha-ha, funny. No I won't... Well I can't say that it's not harmeless but..."

"But...? If it's harmeful I'm coming sis." she replied immediatly.

You stop her and your voice even rises slightly because you were NOT gonna let this day go. "No ! It's nothing you should think about, it's just between Tania and me nothing special really"

"That bitch ? Harmeful...? did she finaly cheat on you ? Or did she start acting unappropriately? Say less !"

"Huh !? N-no ! That's-" Before you could explain anything she hang up on you leaving the silence of the morning in the hallway...

"F..." Tania opened the door behind you and pressed herself against your back looking over your shoulder still sleepy.

"What is wrong babe... Bad news...? Money problem ? Can I help ?" She asks in a really low tone.

"Bad news... For you probably... Sophie is coming" you rub your nose thinking about why out of all days it was today she decided to come. Meanwhile Tania was half-asleep on your back but then she also realised the information you just gave her and stood up.

"Wait... Sophie ? As in your sister Sophie ?"

"Do we know another one ?" you ask with sarcasm

"Why !? When !">Sophie always made her feel uneasy whenever they were near each others.

"I don't know she said something about checking on me or whatever. And she was already on her way when she cal-"

"WHAT!?"

Tania panicked even more looking at herself "Oh no no no no, I must hide... Or leave...! Oh shoot no that won't do..." She quickly ran down the stairs to the front door as fast as her sleepy body possibly let her do.

"The door I need to close the-" But the moment Tania reached the doorknob, the door opened and Tania tripped on the step.

You hear a loud crashing sound at the front door just after Tania's rush and sigh. "Hah~ how can you be this pretty and clumsy at the same time..."

You walk down the stairs just to see Tania between someone's legs with her butt up. The situation looked comical from your point of view but you still wanted to know who Tania had fallen on.

"Door... Ouch... Sorry.." Tania got up and looked down at the person under her holding her back. No it wasn't a delivery, it was your sister. Sophie was rubbing her back while glarring at the almost completly NAKED Tania standing in front of her.

Tania immediatly stepped back in panick and looked away, her arms embraced her breasts to cover them and she cracked a **** smile. "I- I'm sorry... Sorry I didn't mean to I was just-"

But her words were not reaching anyone's ear with this pitch.
