My dad’s 45th birthday was fast approaching. Every year it was something I fretted and worried over as trying to come up with something new and original can be quite taxing at times. Last year it was so close to my mother’s passing that we just sort of let it come and go quietly without a lot of fanfare. Thus I felt even more compelled to ensure that this year’s birthday was one that my dad would never forget.
To be fair, my dad was easy to satisfy, just as most men are. Heck, I knew that just a wakeup BJ and sex in bed would’ve been enough for him but where’s the fun in that? Over the years I’d done a number of things, including role playing (naughty babysitter, dirty French maid, innocent school girl, and so forth), taking him out to dinner or a movie - or both and having sex in public, and even once hiring a stripper for him when I was away at school (no sex, I took care of THAT a couple of weeks later).
Ever since my Aunt Linda moved in with my dad I’ve been living with her daughter, my cousin Kristen. There’s a spare room at the house and Kristen wasn’t all that thrilled about living alone for the first time in her life. The added benefit of free housing was also important as my career as a Christian Elementary School teacher is fulfilling, but the pay is absolute crap. Thus my dad had been subsidizing me to pay for my rent and stuff, something I was glad to no longer have to worry about.
Living with Kristen is ... well, let’s just say it’s “entertaining”. As a recently “retired” whore, she just graduated from Realtor school but she hasn’t totally lost the “itch” that drove her previous “career”. Also, there’s her insatiable passion for sex with younger boys that while it can be incredibly erotic, it is also be a bit disconcerting at times, not to mention tempting - something I simply don’t need if I want to remain a teacher. I considered going to Kristen to get her advice for this year’s birthday celebration but I already knew in general what it would be - something crazy that would get us all in trouble, if not thrown in jail!
In the past I could go to my mom and be assured she would always have something constructive and useful to help me. It was times like this when my heart would threaten to break again and tears formed as my thoughts turned to my mom and I realized yet again how much I missed her. Eventually I turned to the next best person - her sister, my Aunt Linda.
Linda was a couple of years younger than my mom and actually dated my dad back in their high school days (technically she was still in middle school when they started but close enough). My mom and Aunt Linda had sex with my dad and his younger brother throughout their high school years. When my Uncle Jim got married, he had to quit having sex with Linda as his new wife was really uptight about that sort of thing would never have gone along with it.
My dad almost married Linda as I think he had more fun with her sexually (even my mom admitted that Linda was the “wild one”) but his heart was with my mom and fortunately love won over lust. Still, being so close my dad and his now sister-in-law continued their physical relationship. They continued even after Linda married, supposedly to a man who accepted her incestuous background.
Unfortunately, as things turned out he never was able to truly accept her family relationships and forced Linda to choose between her family and her husband - as if there was a choice. Family has always come first in our family and it was really unfair of her husband to be so jealous, especially since they now had a baby girl - my cousin Kristen.
Over the years, my aunt would stop by our house occasionally and disappear with my dad for a while, leaving later with this odd expression on her face. The idea that she and my dad might be having sex never even entered my mind, especially since my mom was usually home during those times. It wasn’t that I would have thought anything wrong with them having sex, I just never even thought about it period.
Once I started having sex with my parents I learned the truth about my Aunt Linda’s place in the family. The two of us even had sex but it turned out to be something we only did rarely after that, and almost always as part of a larger family “event”. Eventually my cousin was included, much to the delight of my dad as you might well imagine. Kristen has always been into younger boys but she enjoys pleasing her favorite uncle and while my dad doesn’t fuck her often these days, I know he made use of her “services” frequently when I was away at school.
Given their history, it was only natural that after a proper period of mourning that my aunt should move in with my dad. Of course, I say “only natural” assuming you DID know about their history. Given most of our family does NOT know about the incestual side of things, you can imagine what was being whispered at the time.
Now that they’ve had time to see them together, people seem to be accepting it more but I know there’s still a bit of tension when my dad and aunt show up together at a family event, especially if they should kiss or get a little touchy-feely. Fortunately, I don’t think the two of the care a hoot about what anyone thinks. Even though they seem close, I can’t see them ever getting married - they don’t have THAT sort of relationship. The important thing is they seem to be very happy being together and that’s what counts in my book.
So anyway ... I decided to seek my aunt’s advice this year as I was drawing a total blank. I stopped by over at the house when I knew she should be home from work yet my dad would still be at his office in downtown Pittsburgh. When I walked in the house nobody answered and I eventually found her on the back deck, soaking in the hot tub. Who could blame her? I LOVED that hot tub and after a long day nothing beat relaxing in the hot water as the jets and bubbles caressed you. Needless to say, it was WHERE those jets were directed that made all the difference - as my aunt obviously was aware of gathering from her position in the tub when I walked out from the kitchen onto the deck.
At first she didn’t realize I was there as the noise of the blower and pump drowned out the sound of the door opening and my steps onto the wood deck. Plus, she was facing away from me with one leg up on the side of the tub, the other with her foot on the bottom. It was my favorite position as well as it allowed one of the corner jets an unobstructed shot directly into your crotch. Oh yeah, it was a GREAT position to be in and judging from her reactions, she’d been at it for a while.
“Ohhhhhh, Godddddd!” I heard her groaning as her head laid back and she closed her eyes, humping herself quickly as if she was being fucked by the hot stream of air and water directed at her hairy pussy (granted, I couldn’t actually SEE her pussy from this viewpoint but I knew she never shaved, despite Kristen’s badgering).
It was a bit chilly this late in the day but not terribly so - enough that I was wearing a light jacket but not so cold that I needed to zip it up. Rather than interrupt her just as it appeared she was about to cum, I decided to watch and wait for the finale. Of course, just WATCHING wasn’t an option. Like, how could anyone watch a woman with Linda’s body, even if she was past her 40th birthday, as she got herself off right there in front of them?
Actually, seeing her masturbate like this wasn’t something I could even remember seeing before. In fact, I couldn’t remember EVER seeing her masturbating alone without someone watching her. I guess technically she WAS being watched now - by me, but that didn’t seem to be quite the same as her doing it right on front of my dad for him to watch and enjoy. It’s sort of funny in a way how something like that can go unseen for so many years.
God, my nipples felt so hard and sensitive! It wasn’t just the chill in the air either that was making them so as I loosened my blouse a few buttons so I could caress my boobs. I eventually undid them all and pulled the blouse out from my jeans so it hung loose, allowing me easy access to my boobs which were practically aching from lack of proper attention.
Thankfully the security fence around the deck hid me pretty much from anyone’s view. The people on the hilltop in back of our house would need some pretty strong binoculars to see anything - assuming they even could tell I was doing anything in the first place to make them even want to look closer.
Aunt Linda had one arm over the side to stabilize herself and from the looks of things, had the other between her legs helping the jets to accomplish their mission. There was that distinctive arm motion that clearly signaled that she was masturbating - and pretty hard at the moment as well. She was groaning and mumbling something that I couldn’t quite make out but I didn’t want to move in any closer and alert her to my presence. Every now and then she would add in a little moan or even cry out a little louder, arching her back and then settling in for more. God she looked so damn sexy!
As good as it felt to fondle my boobs, watching my Aunt Linda masturbating in the hot tub was creating feelings in me that mere boob rubbing was woefully inadequate to satisfy. Leaning back against the brick wall of the house, I reached down and unbuttoned my jeans, quickly drawing down the zipper and spreading them open at the top until I was able to reach in and get to my pussy. My body shuddered uncontrollable as the tip of my finger touched my throbbing clit, sending out all sorts of spasms and jerks that I couldn’t anticipate or counter. Reaching down further, I pushed my finger just a little into my pussy hole and smiled to myself at the wetness I found there. I knew without touching myself I was wet but actually feeling the slick interior of my pussy was always something I looked forward to when I would start to masturbate.
The damn jeans were just in the way! Fuck it ... I pulled them down and the cool late air raised goose bumps on my thighs and the rest of my body but they were the least of my concerns at the moment. The bump I WAS interested in was between my legs, right at the top of my pussy slit where it seemed to become more and more sensitive by the second. With one hand I was toying with my pussy while with the other, cupping my boob and tugging on my nipples. I imagine it would have made quite a sight for anyone seeing us - an older woman letting the hot tub do its work on her while a girl about half her age masturbated as she watched unnoticed!
The jets must have finally accomplished their mission as I watched my aunt stiffen and lift her hips up until her pussy was at the water surface and I could see the darkness of her thick pubic hair just under the top of the frothy water. She was fingering herself and then shoved her hand between her legs. Cupping her crotch and pulling up against it as she cried out in ecstasy as her orgasm began. It was SO hot to watch her cumming, knowing she had no idea her “performance” had an audience, an audience of one, one girl who was getting off herself at the sight of her aunt masturbating and cumming.
“Oh fuck!” she gasped when she finally let herself settle down and take a seat in the tub.
My aunt was breathing heavily and turned her back to the side of the tub to sit on the underwater seat that was molded into the tub. It was then something seemed to catch her eye and she turned to face me.
“Oh my god!” she gasped, jumping a little at first from the surprise of someone watching her.
Then she recognized who it was and her shock change to a seductive grin as she shook her head at the sight of me.
“Damn it Kelly, just how long have you been watching me?” she blurted out.
Then she seemed to finally come to grips with my own condition - maybe the jeans around my ankles and the open blouse had something to do with that, not to mention the strategic positioning of my hands. “God damn it girl, you must be freezing ... get your ass in here now!”
I still hadn’t said anything and so I just shrugged and stripped right there next to the house, leaving my clothes in a pile on the deck on top of my shoes. Now that I was naked the cold was making me shiver so I quickly hustled over to the tub. The water seemed almost unbearably hot after the coldness of the air but I still slipped down up to my neck within a few seconds, my skin tingling from the heat of the bubbling water.
“So ... did you enjoy the show?” she teased me.
For a moment I thought maybe she was implying that she had known all along that I had been watching and the entire thing had been an act put on for my benefit. Then she added, “If I’d know you were there I would’ve tried harder to give you a better view.”
So much for her knowing about me watching. We both giggled at her comment and then she got more serious, or at least TRIED to appear more serious.
