The day went on normal and I trying to hangout with my sister in a more presentable way. I guess that was the day when I started to flirt with an inte...sion to impress my sister. It was weird that I being so close to and she tried to impress her with my jokes, nudges, scares and comments. We then opted to go with my uncle and aunt for a roller coaster ride and my dad being a heart patient and mom being afraid of heights.They avoided the joy rides and were more indulged in sitting and talking and. She is having huge boobs and ass which are gorgeous. Many times I jerked off fantasying her. At day time she is alone in house and her son goes to school and 2 daughters (sex bombs) go to college. I’m also very friendly with all of them as I used to talk to them frequently whenever they come to my aunt’s house and also sujay is very dear friend of mine as we both play chess always. The story happened like this.On Friday afternoon I heard such saying I have a phone call from my friend in her. I gently went down to her pussy and it was fairly hairy. I said “Sis I would love shaven pussy” and took her to bathroom and shaved her pussy. While shaving, I licked and it was very great. She was moaning in pleasure. Then I again carried her back to bed and started licking her pussy madly. She was moaning heavily and pushing my head towards her pussy. Then she said “now it’s my turn”. And she went to downwards and held my monster in her hand; started stroking it. It was already with pre cum.. I wrapped my legs around his waist and heard him grunt even more as I did. Then I felt a feeling inside my pussy that surprised me. I felt his cock go deeper and then felt his balls bang against my hot skin there on the bottom half of my pussy. I moaned extra deep and let it out in a long intense sigh. God it felt so good. Having his balls slap me as he thrust all the way inside me, gave me a feeling that I was satisfying him. He sure was satisfying me.I could also feel his body rub my clit as.
