“Be there at 9 p.m., Tristen!” my mother said excitedly over the phone. Apparently, she, my father Stephen, and my uncle Troy all had gotten together and planned a surprise birthday party for my 48, soon-to-be 49, year-old Aunt Kristy at one of the local halls here in Atlanta, Georgia.

I listened closely as my mom gave me directions on where to go and added the occasional “uh huh” to the conversation, just so she’d know I was still paying attention. “9 p.m. at the Pitino Centre, enter at the rear of the building, and park in the back.” I repeated to my mother, feeling much like a parrot. “Yes, that’s it. Now I have to get back to work, but will see you there, son. Don’t forget!” Before I could reply, Mom had hung up the phone on her end.

At 19, I could think of more entertaining ways to spend a Friday night than to go to my mother’s older sister’s birthday party, where I’d doubtlessly be bored to tears. Spending time with the PlayStation, going to the mall with my buddies, or putting a porno in of Kylie Ireland and her adventures were way more appealing. But I did what I had to do, and if this made my folks happy, so be it. After all, my life wasn’t very difficult now. I worked a part-time job at one of the local groceries and worked out daily to get into better shape for joining the military in the next few months. So until I did join the Air Force, I was just killing time.

My mind wandered to what I’d be doing there at the party. I daydream quite a bit, and so it came naturally to me. I could picture a blonde on each arm as we made our way around the room, smiling at family and friends of the family, the envy of every guy there. But reality has a tight grip on me as well, and I snapped back for a minute. Realistically, I doubted I’d find any cuties there at all, and I’d be lucky not to break out in a bad case of yawns, but again, I’m the kind of guy that does what’s required of me, so I don’t say no to family or friends.

Aunt Kristy is one of my favorite aunts and has always been. She’s got a great sense of humor, and we’ve always joked around and laughed since I was a kid. In fact, I’d spend time at her and Uncle Troy’s house playing with my cousins Ted and Kelly when I was growing up. Now, though, Ted and Kelly have both enlisted in the Air Force, and I’ve been waiting my turn to go.

Unfortunately, both were stationed overseas now, so they wouldn’t be at the party to hang out with me to alleviate my boredom. I thought maybe I could laugh some more with Aunt Kristy, and if nothing else, that would make the time pass faster. That and maybe some Jack Daniels and his buddy Coca-Cola.

It was currently 4 pm and my parents were both still at work. I went outside and did some yard work, mowing the lawn, trimming the hedges, and weed-eating. I made it back inside at 6, shaved and showered, and dabbed on the obligatory cologne, and then played some Twisted Metal on my PlayStation until it was time for me to leave for the party.

During the drive, I had thoughts again of the blondes from my imagination and of Kylie Ireland and what I’d do with her if I had a chance. Before I realized it, I was already at the Pitino Centre, where I parked the car in the back as instructed, then sauntered inside to see what was going on.

As I entered the building, I noticed quite a few people mingling around one another, most with cigarettes and/or drinks in hand. Some I recognized as friends of the family, while others were complete strangers to me. I then spotted my mom, Carolyn, who came over and introduced me to some men and women who were near her in a semi-circle. “Alice, Brent, Lucy, this is my son, Tristen.”

I nodded to all three and shook the man’s hand. The women each told Mom what a handsome young man I was, which caused me to blush. Something I do easily, which is uncommon for a 19-year-old guy. I’m about 6 feet tall, 180 pounds with brown hair and brown eyes, so I think I’m okay, certainly not God’s gift to women, but on the other hand, I’m not the troll living under a bridge either.

I stood there with my mom for a few minutes and continued talking with her friends about my future, work, and interests that I had. They seemed like nice people, but talking to them didn’t excite me like it would if I watched Ron Jeremy fuck some nubile young blonde in the ass. Sadly, it was another world here for me.

As my mind wandered and I began to count the spots on the ceiling (I have a short attention span, obviously), my aunt Kristy and uncle Troy came over, and each gave me a hug. “Hey, Tristen, you’re so big now!” Aunt Kristy remarked, one hand on my shoulder and one holding a bottle of Bud Ice. Uncle Troy merely reached his forearm around my shoulder and gave me a man’s man kind of hug, then let go. “Having a good time, Tristen?” Uncle Troy stated.

I replied back, not wanting to hurt anyone’s feelings, “Great! Just met some of Mom’s friends and learning the fine art of socializing!”

Uncle Troy let out a hearty laugh and shook my shoulder again. “Good thing, you’ll be doing a lot of that when you join the Air Force!” he then whispered, “And a woman in every port!”

As Uncle Troy laughed again, Aunt Kristy playfully elbowed him in the ribs. “Troy, that’s our nephew, and he’s not that kind of a man, I’m sure!” Aunt Kristy laughed then and smiled at me like I were some kind of angel. She always doted on her own kids and on me as well. We were all family after all, and even jokingly, she wouldn’t let Uncle Troy get away with that.

I then noticed that Aunt Kristy was happier than she normally was. Not to say she’s not a happy woman or one with a sense of humor, she is. But the alcohol seemed to help her loosen up even more. In all honesty, I never had been around her before when she had been drinking, so I didn’t know what to expect, but she seemed to be handling it fine and getting into the swing of her party.

I began to look around the room to see if there were any good-looking women present, but quickly realized there weren’t any. I went over to the wet bar and grabbed a bottle of Bud Ice, then sipped it as I made my way around the room again, attempting to find a cure for my boredom. As I glanced around, I noticed Aunt Kristy’s legs in her pantyhose and short skirt. They were very shapely from her years of working out and filled out the hose quite nicely. But then I quickly got that image out of my head. This was my aunt after all, and I shouldn’t be thinking about her that way.

I began to think again about Kylie Ireland when Uncle Troy approached. “Hey, Tristen!” he said as he sipped on a beer of his own. “Can you do me a big favor?”

I eyed him carefully, not knowing what he’d ask for. I quickly pictured him asking me to dump a body or something sinister like that, but immediately dismissed that. I think I had been watching too many Tarantino flicks lately and needed to lay off. “Sure, Uncle Troy, what do you need?”

He then told me of how he told Aunt Kristy how he’d pull the car around back and take her home in a few minutes, but that he was paged by his buddies and was going to go to a local bar to spend some time with them. He then said Aunt Kristy was in the bathroom and he didn’t know how long she’d be, so he’d like me to pull the car around instead and take her back. I think he just wanted an excuse to drive my new Trans Am instead of his station wagon. I’ve seen him eyeballing my car more than once and figured he’d ask sooner or later. I just didn’t expect him to be so sneaky about it.

“Your aunt also is really comfortable in our car, so how about we switch keys and you drive the wagon?” he said hopefully. Bingo! I nodded and sighed heavily. My car was like my baby, but I love my family even more, so I handed Uncle Troy the keys, and he handed me his in turn. He smiled, and as he walked away, he waved and said, “Don’t worry, I’ll take great care of it, and we can trade back tomorrow!”

I nodded in agreement, feeling like I had just taken one up the tailpipe. I slowly strolled out of the building, looking for Aunt Kristy on the way so I could tell her I’d be driving her back instead of Uncle Troy, but there was no sign of her. I walked outside, down the steps, and found where their car was parked. It was an old 80’s wagon, a puke green color, and rusted badly.

I fumbled with the keys and unlocked the door, then slid inside. Not only did the interior light not come on, the whole area where their car was wasn’t under any light source. I used the Indiglo feature on my watch to find the right key for the ignition, then started the engine, which, unlike my car, didn’t roar. More of a cough and wheeze if anything. I put it into drive and pulled up by the stairs. The headlights seemed to be very weak also, and I’d be lucky not to get eyestrain by the time I got Aunt Kristy back home.

I waited and waited for what seemed like an hour, though in reality, maybe 15 minutes or so passed. I saw Aunt Kristy wobble down the steps, the booze having taken its toll. She opened the station wagon door and quickly slid across the seat to me. I turned and before I could say a word, I felt her lips on mine, her tongue fighting to get inside my mouth. I opened my mouth to breathe and in doing so, felt hers move against mine.

I could taste beer, vodka, tequila, and God knows what other kinds of alcohol on her breath. I really was in shock, not knowing if I should be excited or sickened. I liked how her tongue felt in my mouth but knew this was my aunt and it was wrong. That’s until she began to suck on my tongue and run her lips up and down it like she was milking a cock. She did that as her hands moved on my legs, then slowly moving to my crotch where she grabbed my hardening man stick through the material. She let go of my tongue and sucked my bottom lip playfully, nibbling it and still rubbing my cock in the darkness of the interior of the car.

“Aunt Kristy...” I began.

She shrieked in horror and moved to the other side of the car. “Tristen! What the hell is going on?”

I then explained what happened with Uncle Troy and how we switched cars so I could take her home and he could go spend time with his buddies.

“Oh my God! Oh my God ... I was making out with my nephew!” she said in disbelief.

I pulled the car away from the building as she spoke, not wanting my mom or dad or anyone else seeing that my aunt and I had been lip to lip. I pulled under some oak trees and shut off the engine. “Aunt Kristy, I am so sorry and feel terrible. I tried to tell you it was me when you opened the door, but you moved too quickly!” I laughed gently, even though I could tell she was still in shock. I could see she had a tear in her eye, and I used my hand to brush it away. “Aunt Kristy, if it’s any consolation, you’re a great kisser!” I said, trying to again lighten the mood.
