My senior year of college I was living in an apartment about 20 minutes from my Aunt and Uncle's house. It was Saturday morning and I was about to drive to the grocery store when I saw that I had a flat tire. Not sure what to do, I called my parent's house. My mom said to call AAA and have them tow my car to Sears Tire Center and that my Aunt would meet me there. Sure enough, AAA comes, loads my car onto the flat bed truck and takes me to Sears. My Aunt was in the waiting room when I arrived and asked if I wanted to get lunch while we waited for the car. I agreed and we drove about 5 minutes down the road from Sears to Applebees. About 45 minutes after leaving Sears, my phone rang and they said the car was ready. We finished eating lunch and we exited the restaurant. While holding the door for her, she ran her hand across my stomach and said "thank you". We walked to her minivan, which for whatever reason (I hadn't thought about it at the time) she had parked in the rear parking lot, away from the majority of the other vehicles (like behind the restaurant and the road). I got into the passenger seat and she asked if I wanted to get dessert somewhere. I said "no thanks" and she asked if I'd mind waiting for her while she had dessert. (Seriously - even though I was 21, and by no means a virgin, I was completely unaware of what was about to happen). I said "yeah that's fine" and before I knew what was happening, she put her hand on my upper thigh. She told me to sit in the middle seat (looking back it's because the front windows weren't tinted), which I did and she knelt down between the two front seats (driver and passenger) and told me to "take out your cock, quick!" I fuddled around and took out my dick which was rock hard at this point, and she proceeded to not just suck my dick, but practically deepthroated it the entire time. It only lasted about a minute before I felt the tingling sensation (reminiscent of my first time jerking off it was so intense) and told her I was gonna cum. She let out a deep moan of approval and just kept sucking...holy fuck was it intense. I just kept thrusting and bucking my hips into her mouth and she sucked me dry. So that insane sensitivity begins to kick in as shes sucking the tip of my dick and I tell her to stop and try to stop shaking and she just keeps sucking me off. About 30 seconds later, she wipes her lips and gets into the drivers seat. My dick is still rock hard and I climb into the front passenger seat. She very casually starts the car, turns the heat up a few dials and without saying a word to me just drives to Sears. She parks the car and goes inside with me. I start taking out my wallet and she motions for me to stop, and settles the bill. I thank her and she just smiles and says "thank youuu." We start walking out, my car was in the neighboring parking lot to where she had parked her van, and when we get to her van she gives me a very mild hug. Unsure what to say or do, I say "thank you so much." She just smiles and says "if you ever need anything, just let me know." That was in 2009, we have never spoken about it. The only reason I'm writing this all these years later is because last week we had a small-semi-family reunion, and when I came out of the upstairs bathroom, she was walking towards it. I just smiled and as I walking past her in the hallway, she looked behind her to see if anyone else was around (which they weren't) and just places her hand on my groin and says "it's so good to see you." She has a really great ass, but shes sort of let herself go and put on a lot of weight. Part of me thinks it'd be hot to do it again but another part of me thinks the risk and shame isn't worth it. Am I wrong to avoid it?
