Aunt is giving me my best birthday ever!

So this is what actually happened with me and my aunt and I would love for you to re enact it forme. Setting is that it's my 18th birthday and my aunt has asked me to go shopping with her before we go to my birthday party. After a LONG boring day of shopping she decides she wants me to go to her house so she can try on her new outfits and I can pick the best one for her to wear tonight. I try not to be be rude and agree to do it. I have a seat on her bed while she goes in to the closet and changes. When she goes in for the second change she leaves the door open a bit by accident and I see her completely naked! I try to hide it from her but she can tell I saw something. She says it's no big deal, because I am 18 now, so then she just changes her clothes right in front of me! I can't help but get a huge boner! She is so cool she tells me to go ahead and jerk off to her changing, even bends over so I can see a little better, but next thing I know she is kneeling in front of me taking her top off and then sucking my cock! She finishes me on her tits and then gets dressed like nothing ever happened! BEST BIRTHDAY EVER!
