Lust For My Aunt

I have had a crush on my aunt since I was a teenager. I was attracted at first by her fun personality, always laughing and having fun......she was the "cool" aunt. As I was coming into my early teens and being perpetually horny, my attention was now being focused on my aunt hardly ever wore a bra.....perfect b cup tits, nipples always poking thru her shirts, and that fun loving personality to go with it. She always wore skin tight pants.....that was the fashion in the 70's.....and I loved it! Knowing now what a camel toe is, my aunt and her super tight jeans or shorts, was always sporting a camel toe. The first time I remember seeing her in a swimsuit it was a one piece, and yellow in color, and I can remember being able to see the outline of her nipples and the darker color of them showing through, and being able to see a strip of pussy hair showing ever so slightly when her suit was wet. My mother and other female family members also wore similar swimsuits, so it wasn't out of the ordinary to see my family and the sweet bits that they showed, and never gave it a thought as it being inappropriate. Fast forward to 5yrs ago.....my unce had passed away, and my aunt has been lonely ever since. I stop every now and then to visit her, and when we hug it's felt like the hugs mean something more than just hello or goodbye. They are very tight hugs, with her face nestled in the crook of my neck, and when she does that, I can't help it but my dick gets hard. I can feel it pressing on her thigh so she has also got to feel it right? Before I finish, let me tell you that I am 53 yrs old and my aunt is now 70, and she has always stayed trim and fit, and still hardly ever wears a bra, and in my eyes still very sexy with a body you wouldn't think of a 70 yr old woman having. Through the yrs there's no telling how many times that she was the focus of my dick stroking, and I've never lost that crush for her. On my over to our last visit I was trying to figure out a way to find out if those hugs had a special meaning to them, so when I got there we hugged and again she nestled her face in the crook of my neck......I jokingly said that she better stop that cuz she was making the fun fun parts of my body tingle......she laughed and started to pull away and I laughed and said.....wait, do it again! I am already starting to get hard as she puts her face back on my neck and squeezed me harder and gently kissed my neck up and down.......my dick is at full rock hardness and I'm gently pressing into the top of her thigh, and next thing I know, she starts pressing back! I started kissing her on her neck and she started rubbing my dick through my jeans. I slide my and up her shirt and those little titties and hard nipples felt so good to finally touch after all those years staring at them.......pure heaven! I slid my right hand down the front of her jeans to her pussy, and I swear I my knees buckled when I felt that her pussy was absolutely smooth......totally pure free and wet! I thought how fuckin sexy that a 70 yr old woman shaves her pussy! So after a few minutes of feeling each other's fun fun parts, she backed away and says.....omg.....I haven't felt like this in the 5 yrs your uncle has been gone. She said that she needed time to think things through before it went any further......and I told her no pressure......and I loved her no matter what happened, or could happen in the future. We sat and talked for awhile, I confessed to her about my crush, and still think that she's just as sexy to me today as she was back in the day.....she kinda blushed and said thank you, and that as I got older and grew into manhood, that she always thought that I was so handsome and got better looking with age. We gave a goodbye hug......her feeling down and held my crotch as my dick got hard......gave it a squeeze and said she would be in touch........it's been a few days now, and my stomach is constantly having that butterfly feeling waiting for her call. I am married so I know it's wrong, but I have wanted her for so long, and I'm having trouble with telling myself to not go through with it if she gives me the green light.......someone please give me some advice!!!
