Around 10 years ago, my niece came to spend the night with me while my wife and kids were out of town. We went and rode ATV's for a few hours, and I ended up getting pretty buzzed. Around midnight I said goodnight to my niece and I went to bed and pretty much passed out. Some time later, I woke up to my niece in my bed kissing my cheek with her hand rubbing my chest. I asked her what she was doing, to which she replied, "it's ok, it'll be our little secret". I went through the whole "it's not right, we shouldn't be doing this" blah blah blah. She started kissing me, and making out with me while she pulled my boxers down past my knees. She then straddled me, and started grinding her panty covered crotch on my hard c**k. So I gave in and just let it happen. I pushed her t-shirt up and played with her tits, and sucked on her nipples while she continued to grind on me. Fifteen minutes later we both orgasmed at the same time, she kissed my cheek, said "thanks Unc, I really needed that" and she left my room. Suddenly I was fully wide awake, boxers down past my knees with a big load on my belly and my bedroom door opened a few inches. To this day I'm still not sure if it really happened, or if it was all just an amazing dream. The next morning nothing was ever said about it, and she was acting like nothing happened, and no mention has been made of it all these many years later. Hopefully she reads this and lets me know it happened or not.
