We then went and changed into our night clothes and settled down on the sofa with the popcorn and smoothies. Elizabeth put on baby blue Victoria Secre...t pajamas. The top was a button down shirt with 4 large buttons and soft blue satin. The bottoms were matching boy shorts that showed her beautiful long legs. I put on a pink lace teddy with matching panties and had a satin matching pink robe over it. I had picked the prettiest lingerie I owned. At first it was a little tense as I think we didnt. ." Oh. No she hasn't. There will be a little change in our usual Saturday activities. We have to stay here, we can't leave her on her own, can we?" WHAT?!" Oh, it's no big deal. She'll be almost naked too." Yes. Yes I know that! I have seen her for God's sake!" Good. Now get ready. Dinner in half an hour."A little dazed I made my way to the bathroom, showered and put my white teddy-bathrobe on. I would be damn if I was going to sit down at the dinner table naked in front of my sister! Her being. I smiled as I rummaged through the bag that you had brought down for me for clothes that I hadn’t seen in almost half a year. Once we were all decent we gathered the k**s and went out to the car. The boys piled into that back seat and I opened the door for you. You made sure to spread your legs widely as you got in to ensure that I had a chance to enjoy another glimpse of your pussy. As your legs spread it actually caused your cunt to gape just a bit, giving me a peek at its luscious pink. The biggest flaw in my plan. I was his daughter.No matter what I wanted to do - I was his daughter.‘Fuck it,’ I thought. ‘fuck…fuck…fuck!’Still it had to be attempted, otherwise I was now going to go through the whole day and every night with this switch going off and fucking me up, with no-one to fall back on.It was about a day after I saw my dad’s cock when he was drying himself that I decided the bathroom was a good place to start. I had planned it for the evening. I waited until we were.
