Eat up your sister

"Isabelle was left really dirty after our play session, clean her up" Lucas comanded pointing at Isabelle's used, cum dripping pussy.

"Of course master, I'll be right on that" Dizzy said trying to grab and lift her sister on her arms and take her away so she can take a bath but her master stop her by putting his hand on her shoulder.

"Oh no silly girl, clean it up with your mouth like bitches are meant to do" he said in a condescending cheerful tone, Dizzy gasped at the mere idea, it was disgusting, she was her sister, how could she ask her something so wrong, Dizzy wanted to say no, she could take whatever alteration to her body that he may want to make but making her **** her own sister? that was the worst thing he could ask her to do, Dizzy wanted to say no but she knew she had no option, if she refused both of them would just get punished worst, she let her sister laid on the desk again and while forcing the best smile she could muster she pressed on.

Or at least she tried, as Isabelle's legs were spread open and her cunt wide open to get serviced Dizzy was struggling to collect the nerve to eat it up, she pulled out her tongue and pulled it back like 5 times, this was so wrong she wasn't sure she would be able to to do it, at least not until her master grabbed her by the back of her head and shove her face against Isabelle's cunt "stop messing around, lick my cum off your sister's bitch cunt already" Lucas said in frustration, his friendly facade abandoned for the moment, Dizzy at that point finally began eating up Isabelle's pussy like she was commanded to, once she got going it became easier to press on even if it still felt wrong the entire time, Isabelle knew it was wrong too but she still couldn't help but moan in pleasure as her new sister eat up her pussy, which made her feel even more wrong as a despicably dirty slut for enjoying a **** act of ****, Dizzy felt just as ashamed as her tiny ding-a-ling was getting hard showing she was getting pleasure from this too, even getting erect it still remeained adorably small.
