Mom and dad are finally selling the house, and it's almost moving day. Sis and I can't believe this will no longer be our home, as we have so many memories in it! We used to wrestle and fight, cry and laugh....and even not told on each other when we would sneak the opposite sex over to fuck...lol.
But then my little sis brought up a surprising memory of how when we were little, we would take off all our clothes and go swimming in the pool buck naked together. She asked me if I remembered doing that?
(Of course I remembered, it's something that I have thought about many nights while pleasuring myself....but why is she asking me? Could she be testing me right now to see if I wanted to play with her?)
Then she asked me something that I have dreamed she would ask me.... Did I want to go skinny dipping with her again?
(I wasn't sure how to respond, but what I didn't realize was that my cock was already responding.)
After she took off all of her clothes, and got me to say yes to getting up and getting naked with her....she looked down and realized that I had a huge boner bulging out of my shorts!
(I was so embarrassed!!)
But my little sis couldn't have been any nicer about my growing situation. She calmed me down, and reassured me that she wouldn't tell anyone of my reaction. She said it was normal for a guy to react this way to a naked girl, even if it was his own sister.
Then she explained that since I was hard, how it would be a shame to let it go to waste. Besides....she was always curious to see how her big brother's cock looked....and how it felt!
Watch at the end how I blow my load all over my sis's little bush and her open vagina lips...
