I have fanisized about my wifes sister for years. She loves to show her cleavage around me and flurt alot, which pisses my wife off. To cap it off my niece loves to whear very short skirts and her panties almost always are ceaping up her ass. I see it all the time when they are over at our home, She called one day and said they are coming over and she asked me to get the coffee ready.

SO I jacked off into a coffee cup, it was a HUGE load. All i could think about was my dick in their mouth as I was cumming. I mixed in alot of creamer and then made the coffee. I was flurting very heavy with them while they drank it. I even made a comment about maybe next time i could add a little special creamer next time. she smiled and then said your bad.

I have thought about this many times and I am looking forward to unlading all my cum into one cup next time and then watch her drink it.
