Normally Sapphire would have a bath on her own, but with Rouge's bath not working, Rouge asked to join her for a bath, so they could wash each-other...

While unsure about it (and rather blushful) she went along with it.

Sapphire undressed herself before stepping into the bath, her sister followed afterwards trying to not look her sister's naked body...soon they were both in the hot steamy water, as Rouge started to rub Sapphire's back with soap...causing her to blush a little.

Rouge: Told ya this was a good idea, try not to blush so much, we-re sisters afterall I know I what you look like under all them bubbles...and you know what I look like too..

Sapphire: S-sorry sis, it's j-just I never shared a bath with anyone before...

She couldn't help but enjoy Rouge washing her.

Rouge: *giggles* well there's a first time for everything sis.. can you rub the soap into my back now please?

*passing the soap over to Sapphire*

She started to wash Rouge back, causing her to blush more... but slowly warming up to the idea of them sharing a bath.

Rouge: That's it sis...*giggles* We should bath like this more often.
