She's Now Fucking Like There's No Tomorrow.

My 27yo sister who still lives with our parents is visually impaired. Having a master degree in law, she spent most of her time pursuing other studies. Before she started working at a law firm i first started noticing her acting a little strange than normal. When we were much younger we use to share conversation about being a virgin which she were even at age 24. Sometimes we talk for hours about sex and i use to notice her sitting very awkwardly. On a number of occasion i steered between her legs that were opened wide which lead to me getting a boner. I often felt dirty after steering but her pussy that were clearly seen through her mesh panties were equally hard not to look at. She is a very beautiful young woman with a huge ass and a pair of stiff nipples to die for and her pussy is always shaved.

Now during a very hot topic discussion one late night her strange way of acting took a unexpected turn. The argument spins quickly as she awkwardly asked me if my girlfriend (who is now wife) is pleased when we are having sex. I paused for a while, then she said "remember we can talk and this is between us".
I then went into details about our sex life then i notice my sister actually sweating with her hand slotted between her legs as she nervously squeezed them.
She then make it a duty to engage these sexual conversation with me as i watched her reaction escalating. Horny for me is now an understatement as i started to get the drift more and more. My sister after 24 years of books, books and more books plus being visually impaired with no intimacy along with no sex... She is now horny as the word described her. 'She definitely wanted to be fucked'!

She never said she wanted me to do her but i knew for sure that she wanted me to. It was one Saturday afternoon when we were alone. I knocked and she invited me inside her room. We started out usual chat. I then turn it sexual and finally conclude that it gets her very horny. Her hands were once again between her legs as she squeezed. I quietly went closer to her and hold her hand. She gasp in a way that tells me one thing...'take her'. I then remove her hand from between her legs easily then i touched her crotch, only to witness the amount of wetness that were dripping from her pussy. She used both her hands to cover her face while i licked her wet pussy. She made one of the weirdest sound ever as she moaned with pleasure. I licked her every night thereafter and when she could not take it anymore she grabbed on to me aggressively and pluck my cock out and rode it to a bloody ending. She is now 27 and we are still fucking even though i'm married and have a young son. She is doing well at the law firm and she's more happier these days than before. Her pussy is so tight and whenever i inserted my cock inside her the muscles in her pussy is so strong it milked cum out of me within minutes. She were blind to sex but now she's getting everything after years of studying for her future.
