Exploitation of Innocent cousin sister AMMU

[Pradyumn]

With her huge ass just in front of my eyes, I couldn't believe all this to be true, I slapped myself slightly and began my adventure. First I held the elastics of leggings on both the sides and tried to expand it. I could see some gap formed at both sides, now with one hand I took support of her back just above leggings and held the middle elastic and tried to expand, now I could see a bigger gap formed. But in no way sufficient to push her huge ass cheeks bit by bit. I thought lesser the gap, more I could fondle her ass. 

" Let's begin " I said and I touched the bottom of her both ass cheeks. I began to feel her big cheeks and feeling edges of the underwear which could cover only 60% of her ass cheeks. 

" Ammu, your butt is actually very stiff and tight which would make it difficult to push it out" Saying this I pressed both of her ass cheeks as if it were some auto horn. And just after that I gave her a light smack from the back of my hands and asked 
" Are you actually holding your ass muscles tighter ?" 
" No Anna " She replied. 
" Okay. Hold it tighter once. I really want to check " 
Now I gave a harder smack and it didn't shake a bit. It was hard. 
" Yeah. You were right " I replied.
Felt her ass again and now I did what i desperately wanted to do. Gave a bit harder smack outside her pantyline and enjoyed how it shook. 
" Sorry Ammu. Just wanted to see the difference. Your ass is relatively stiff."

From the back of her thighs, I raised my hands, at the same time moving layer of fat with it. It reached her ass cheek, and I increased the pressure, moved her both the ass cheeks till wherever it was possible. I could now see some of her skin roll out of leggins. I asked her to rise her t shirt so that it doesn't obstruct my view. Then I tried to pull her leggings down as much as possible. It stopped at her ass crack. I could see a small line of crack which while coming down separated her big cheeks. I just had to get some fat out of it, so that I could slide the leggings down and look at her half enclosed ass. 

Now I wanted to peacefully play with her ass. I started kneading her complete butt as if it's wheat flour. In the way, I also inserted my fingers inside her pantyline. I roughly pinched her multiple times. She gave me " Ow" then. Through inserting both my thumbs insider her pantyline, I moved my hand towards her ass crack. And when both of my thumbs had reached slightly re inside and bottom of her ass crack, I raised rest of my fingers above it. Now with both of my thumbs inside her ass crack and rest of my fingers on bottom of both of her ass cheeks, I simultaneously completely separated and lifted both the ass cheeks. I certainly heard a " Ahhhhh " escape from her mouth. I squeezed both the ass cheeks and released it. 

I held the pantyline on the middle of her ass and pulled it to centre. From where I was sitting her panty had actually become like a thong. Out of nowhere my phone started to ring!!! Was freaked out for a second thinking it was doorbell. I received it and told my uncle I would book a cab. So now I had final 30 minutes to remove her leggings and get "darshana" of her huge naked ass. 

I sincerely tried to push her cheeks outside and at the same time trying to slide the leggings. And step by step, I could see a longer crack. After 15 minutes of honest effort, I could feel that her legginsl could come down anytime with a stronger pull. I can now see her red panties, which was exposed because leggings had been pulled  down. I actually thought of pulling leggings with panties, but it would have been much difficult. I now knew they could come anytime, also wasn't sure about these type of opportunities in future, therefore without even minding what ammu would think:  I stood up. 

I dragged her in front of wash basin so that her back facing mirror. I kneeled down infront of her, in pretext of pulling her leggings down : 
I started from just above her knees and moved it till my thumb touched her pussy. Put one hand on her inner thighs and squeezed it and moved up and squeezed again. I reached even the gap between her thighs and pussy. Ammu had closed eyes and was biting her lips. I spreaded her legs a little wider and brought my hands in between her legs. Now first holding the thin cloth of leggings to pull and then covered her entire pussy and CUPPED HER PUSSY. Heard another "Ahhhhh", I looked at her now releasing her pussy. She was looking at the cieling with her mouth wide open eyes shut. 

I switched to geniuenly pulling it down and got everything ready. For the final pull. 
" Ammu, it's almost over. "
Again dragged her back to where stool was kept and looked at the timer I had kept. I had 7 more minutes minimum. I didn't want to take chance. 

I sat on the stool and turned her ass towards me. I could easily pull it down now from her ass. I started to pull her panty to centre to make it look like thong. Everything was set. And I finally pulled her leggings from her ass and it fell on the floor. There it was an humongous ass , 90% of her ass cheeks uncovered. As soon as it fell, woman instinct ( or dumb) made her to bend down and pull up her leggings. I stopped her hands and asked "WHAT ARE YOU DOING". 
Ammu was blank and she stood up without knowing to do or say. I asked her to lift her leg so that I could keep her leggings away. I looked and admired the way her round cheeks are protruding and how nice it would be to play with it and bite it. Her ass was fairer than her face or hands. It was wide and without any marks. I stood up looking at that and kept my hands on her shoulder pushing a little bit in front of mirror area. She hadn't realized yet about her thong situation yet. I pulled out the stuck panty out and covered her ass with panties.
