Practising With Naive Little step-Sister

I'm your little step-sister. I come into your room at night because I saw you spying on me in the shower. What were you doing? You tell me that you were making sure I was showering right. I'm so naive that I say ... that makes sense! I guess it's like Daddy when he helps me "practise". He wants to make sure that I do that kind of stuff right, too. What am I talking about? Well, I'm not really sure how to explain it ... so I'll just show you. I get down on my knees and take your cock out of your jeans. Daddy told me to call it a cock! I start sucking on it just like I do with Daddy. Daddy really likes it when I do this - do you like it too, big step-brother? Daddy also likes to play with my boobs. Do you want to play with them, too? I stand up and take off my shirt so that you can squeeze and jiggle your step-sister's tits. I take off my panties so that you can squeeze and smack my ass, too. Do you want to see my pussy, big step-brother? Daddy loves when I show him my pussy. I lay on the bed and spread my legs to give you a good view. Do you want to know what else me and Daddy do together, step-brother? I'll show you Daddy's favourite thing. I tell you to lay down and I get in position to start riding your cock. Don't worry, big step-brother, we don't need a condom! Daddy says that you can't get pregnant if you're related. That's why I can practise with him whenever he wants - and uncle, and Daddy's boss sometimes too because Daddy says that it's LIKE he's related. And none of this counts as real sex - it's just practise! That's why I'm still a virgin. I'm Daddy's little slutty virgin. Daddy just wants me to practise lots so that when I do this for real with my boyfriend, I'll be really good at it. We can practise together too, now, big step-brother! We finish up our practise with you cumming in my mouth. I eagerly swallow it all down. Wow, I hope real sex feels as good as practise!
