The day came and mom and dad waved goodbye, Amy and I waved back and off they wentwe imidiately shared the money they left and decided to get a pizza for that evening, ah life aloneit would have shocked our parents to see us getting along this well.The evening went with tv watching and a few board games but around 18 Amy said she was bored, I asked her what she wanted to do then, how about a game of strip poker she replied?I really hesitated, I mean she was my sister after all but I remembered her in the shower and gave in, I AM a poker shark, no if's or doubts there, in matter of an hour she was butt naked in front of me. Ah I don't want to stop playing she whined, but I have nothing more to take off, I laughed and thenshe came with a suggestion that gave me a instant boner, Let's continue playing, if I lose next round I have to jerk you off, alright she got it her way, she lost and I got naked and ready.Her soft little girlyhand closed around my hard cock and she started sliding my skin gently back and forth, it was almost too much to handle, she giggled at me and got a little faster, seconds later I spasm and thecum starts shooting out all over the cards and her hand, Wow big brother you sure needed a cum, she laughed again.Believe it or not she wanted to play more, this time she said she was going to give me a blowjob if she lost, alright I said full of hormones but this time I lost miserably, so she commandet me to lick her since I was already naked, my sweet hot sister laid back on the poker table and spread her legs, opened her steamy virgin crotch to me and waited, I almost fainted when I ran the tip of my tongue across her virgin lips, she was oozing of girly precum and I started licking intensely, swirling my tongue around her crotch into her virgin pussy briefly licking the membrane of her indeed intact virginity, Amy was moaning and screaming high now and she came without a warning all over my face filling my mouth with sweet girl cum.After a few minutes calming down she wanted to play more but this time she wanted the prize to be a wildcard, she told me that if she lost she would do something to me but she wanted to do whatever she wanted to do, I agreed.
