The best sister ever Part 2

Once she had managed to fit 2 1/2" of her cock in her mouth she did the same treatment for me and pounded away at my ass and this time it didnt hurt as much. Before either of us came my sister announced we should take a rest and calm down and she would expain to me. "wow kiddo that was amazing your a real cock slut are'nt you, how do you feel about a sucking race and the loser has to swallow all of the jizz?"

We both positioned ourselves and started sucking at the same time and it was the wierdest feeling ever sucking myself so fast that I nearly came straight away but could get the last step for another minute. About 1 seconds before me my sister blew her load all over her eye and even on her tits. "hah you lose now eat your cum u little slut!"

With that I blew my load more forcefully than last week and filled my mouth till overflowing. "wait I'll be nice you dont need my cum but instead ill put it in the dinner you going to have later". For the rest of the day we took turns sucking ach other and cumming on each other and eating it. I said to my sister before she gave me my cum dinner "best 2 out of 3 tomorrow?"
