First time with older cousin

Hi, I'm 19 years old, I'm white, blond hair, 5'10", 180 pounds, and my cousin is 21 years old, she's white, curly hair, 5'10", 110 pounds. I had gone to her house, when I called her no one answered...after about 5 minutes of calling her she appeared in the window rolled up in the towel telling me to go in and wait in the room because there was no one at home and she had come out of the bathroom at that moment. I went in...I sat on the sofa, I turned on the TV and then she appeared with a mega short shorts, bra and wet hair. When I saw her I almost had a piece, I even said a little girl: "Beautiful body in Paulinha!!", she laughed and went towards the kitchen ... gave her some milk and "unintentionally" let the milk fall on her wonderful body !!! she laughed and I said that I was going to take another bath. I said that I didn't need it and then I started to lick the milk spilled on her chest ... she resisted and left and went to untie the lace of her shorts. I didn't even notice I stuck her on the sink, I took off her bra and started to lick and lick !! and then I started to go down her panties ... When I saw her pussy I had a piece of naun I couldn't stand it and it fell out of my mouth...she deluded I took my stick that was a stone and I put it nice!!!she wanted more..I put it back if I supported in the sink and I buried it all...I did what she said and colokei fast...and I was dying of erection GOZEI!!!GOZEI!!! We stayed there all afternoon, then I went home happy with my father all hurt by so much fucker.
