I arrived home from work and my brother was waiting for me saying can we have a chat I want a female's perspective on a subject. He said he had only mentioned that England were playing tonight, and she went all erratic.  You remember when I called to watch that Newcastle match showing on Sky, well when I got home my wife went ape shit, saying you have visited that slut of a sister to watch a football rather than staying here with me. He said to her why do you call her that she remarked well around the house she hardly ever wears appropriate clothing is there something going on between you two. I guess she has serious insecurity issues coupled with stupid jealous feelings. He said I would never dare to tell you how to dress in your own home and in my opinion, you look great, showing off your awesome body I said it would not make any difference anyway.  

He said I want to come over tonight just to teach her a lesson, but it would probably backfire on me, maybe if she saw you in your work clothes it would more than likely change her mind, I said I need to change out of these to keep them looking good, I was feeling mischievous thinking what should I change into, maybe a skirt and top, a short dress, or yoga pants and vest top, I asked him what does she call inappropriate dress? She has noticed your clothes show you are not wearing underwear, I said as you are here tell me what to change into, he said yoga pants then you are not showing anything, I put on the tightest sheerest white yoga pants I have coupled with  a short drop arm vest.  he said stop playing games with me they are so tight I can clearly see your camel toe and the full outline of your pussy, and your tits are virtually dropping out of that vest.   

I replied to him, and I can see by the bulge appearing in your trousers that you do like to see me like this. He replied stop it you are my kid sister with you in those yoga pants you don't really need to be wearing them as I can everything on show I said Well you must like the view as it has not stopped you staring at my pussy mound he said this is turning you on playing with me  isn't it, I said maybe it is and you too and if you look at my pussy mound you will see my pants getting transparent with my leaking pussy juice making me more visible, I said to him do you want me to change into something else then, he replied it would be more sensible as I only called in for a chat not expecting my sister to be showing off in her yoga pants, I said ok I will be back shortly. 

I went to change thinking shall I be more sensible or flirtier, so I removed the wet yoga pants but left the vest top on and now coupled it with a short mini skirt I sat opposite to him twisted to the side so one of my tits were sticking out from the vest he said what are you trying to do to me first off you had your pussy nearly covered in your yoga pants but now it is on full display I said that your wife calls me a slut in how I dress so I want to prove to you how I could look the next time she visits with you, do you want me to dress like this? he surprised me by saying definitely no not for her but I am loving the show of my little sister being the slut so open your legs wide for me he said pull up your skirt I obeyed his commands he said stoke your pussy I obeyed once more by now I was extremely wet, he said take that vest off and caress your tits I happily obeyed my nipples were erect and very hard, he reached down and started to finger my sloppy wet swollen pussy he had four fingers inserted and was working it hard I unzipped his jeans to release his cock I was seeing it for the first time he was big rock hard with the head glistening in pre cum I licked it off he tasted great I then took him deep we carried on pleasuring each other for ages finishing off with a great fucking session, he kissed me so passionately and said this is so taboo but I don't care I have wanted to have you for as long as I can remember I said I have no regrets either being fucked by my brother was absolutely awesome and please call round whenever you want I will be your own model. I said as he raised up off my body now come here and let me lick you clean, he absolutely loved that he said a slut yes but my slut now I love it.
