Could you look after Tara tonight?

"Of course i can but why?" Kate said flipping her blanket off and swinging her legs out, "i was hoping to ask Abby to do something for me" she replied, "I'm actually glad to hear that i know Abby still feels so much guilt about what happened" her mom said, "actually what i have in mind might help with that so if you don't mind sleeping in Abby's room tonight it would really help" Lara said, she then waited in the room as Kate went and got Abby for her, "mom said you wanted to talk" Abby questioned after coming in and closing the door behind her "yeah there was something i wanted to ask if you could do for me, you know i spent all this time as panties but you probably don't know that i slept on owne.. sorry Misty most nights so being away from her and human again is making it impossible to get any sleep so would you wear me tonight please?".

Practically jumping at the chance to help Lara Abby began stripping off right away, Lara was able to get a good look at her sisters naked body which she hadn't seen since the shower incident that started them down this road, she had changed quite a lot in that time her eighteen year old body which back then had been quite toned now included a little extra padding, her modest breasts had ballooned to more than double there original size and now slightly hanged down with the extra weight plus her nipples and areola had darkened from there once pink colour, Lara subconsciously cupped her own breasts in her hands wondering if hers would do the same should she have a child, lastly Abby's face had matured and her hair was much longer, Lara had always found her sisters body quite sexy and surprisingly the changes had only made that worse as she found herself getting a little wet at the sight of her sister stripping for her.

Once she was naked Lara started her transformation into a pair of black panties which Abby immediately recognised as she had seen them in her nightmares for years now, picking them up she hugged them tight "i'm sorry" a small whisper escaped her lips before she put them on, that night both Lara and Abby slept better then either had done in a long time, over the next week the sisters slept together every night and as they did they ended up spending more and more time together before and after sleeping until eventually Lara couldn't hold her attraction back and asked Abby out for a day in town just the two of them which secretly was more of an actual date starting with clothes shopping followed by a movie and finally dinner at a restaurant, throughout the day Lara noticed just how much Abby had matured not just physically and that she actually felt safe with her sister now, whether that was from the extra years experience, the responsibility of having a daughter or just from Abby looking after Lara at night she didn't know but it did help explain why she felt the way she did.

That night Lara decided she had to say something so she asked Abby....
