Blackmailing Aunty

Please note, the aunty in this story is fictional, not a real relative.

I�d been lusting after my aunt Sonia for about 2 years now, it started when I caught a glimpse up her skirt and saw her stocking tops and a pair of damp knickers. I�m sure she let me see the view on purpose and yes I got an instant hard on.
Between then and now I had also seen her pussy, both hairy and bald, with and without knickers covering her pussy, sometimes only tights and no knickers. All had the same effect, a hard on and wanting to do all sorts of things with her pussy.
Each time her and uncle Dave went on holiday I was the one to look after their house, and what an eye opener it was for me. Her lingerie drawers were full of very sexy underwear. I used to sniff her dirty knickers from the laundry basket every time I visited, but when they were on holiday I used to dress up in her lingerie and outer wear.
I even found her stash of the toys. Not just dildos and vibrators, but a harness for the dildos, floggers and other things I knew nothing about. I even put a condom on the smallest dildo and pushed it up my arse and wanked off into a pair of her knickers.
I had a plan in mind to get what I wanted from her, and it wasn�t just to finger her pussy. To get it I had to do a lot of work.
The plan was simple, I knew she was a bit of a slut with men, so I was going to film her being the slut I had heard her to be. Every time I would film her I would make sure her face was in perfect view. I would present her with the videos and blackmail her into being my personal slut.
Well for 6 months I had filmed her giving blow jobs in alleys, getting fucked by 2 men at the same time (spit roasted as well as in the pussy & arse at the same time). I even managed to film her pissing in an alley, then fingering herself to orgasm straight after (that one I wanked over every night).
The time had come to show her the evidence and start getting my pleasure from her. I turned up when I knew uncle Dave would be out. How I saw her dressed pleased me, short skirt just short of the stocking tops, seamed stockings, high heels, a white blouse that showed the design of her pink bra underneath. I�d seen the bra before and knew she would be wearing the matching knickers.
I told her I needed a long chat with her, she told me that she had an appointment to get to. I told her to cancel it as I had something to show her. I showed her just one of the videos on my mobile.
She sat down and started shaking. I went to her stool and put my hand up her skirt and started to fondle her pussy through her knickers. I told her to cancel her appointment as I fingered her pussy.
After she came off the phone I ordered her to remove her knickers and hand them to me. When I got them I sniffed her juices, she had got really wet.
I took my cock out and told her to suck me and make me cum in her mouth as I sniffed her knickers. She got to her knees so quick I was surprised. As she sucked me she cupped my balls and fondled them , at one point she teased my arse hole with a finger.
When I shot my load into her mouth, she swallowed and jumped up and took my mobile. I knew what she was doing and told her not to bother as there was lots more videos of her acting as a slut. She looked at me and put the phone back on the worktop and looked at me pleadingly. She was almost in tears and strangely I was enjoying it.
I told her that for me to keep quiet, it was easy, she would have to let me do whatever I wanted to and with her in any way I wanted, but I would not put her in any harm or fear of being found out what we were doing.
I told her the first thing she would do for me was to get naked upstairs as I watched and go to the bathroom, where she would stand in the shower and let me watch her piss. When she had finished I would lick her pussy til she came.
She tried to get out of it, but I told her that she really had no choice, so she went upstairs with me behind looking up her skirt and seeing the stocking tops and commenting that her arse looked so sexy that I would love to fuck her on the stairs right now. She responded by lifting her skirt, pulling her arse cheeks aside, kneeling down and telling me to do her right there.
I obliged and could not last long as it was so horny to finally fuck my aunt like this, I had no condom on and pulled out of her pussy and spurted on her arse cheeks.
As she stripped for me she became shy and tried to cover her nipples and pussy. I told her not to be so shy as she normally flashes her pussy at me every time I am around her. She explains that what she does to me is to tease me.
When she is naked I tell her to bend over with her hands on the bath edge. I then spank her arse, telling her this is for teasing me with horny views up her skirts and of her pussy. I tell her that had she spoke to me privately I would have loved her to take my virginity, and let her use me for her sexual pleasure.
I finish spanking her arse when it is a nice red and very warm. I tell her to get in the bath and stand with a foot on each side. I get naked, sporting another hard on, that she smiles at. I get in the bath and kneel between her thighs and tell her to piss. Initially she can�t, so I turn a tap on and she lets go with a nice hot piss flow.
When she has finished I start probing her wet pussy with my tongue, swirling from the outer lips inwards, she thrusts her hips towards my mouth and starts moaning. Her moaning turns to gasps as I find her clit and nibble on it and suck it. I get really rough with her clit and she is jerking a lot, when I stick a finger up her arse hole, she loses it and squirts in my mouth. She apologises and begs me not to punish her. I stand up and snog her while pushing my cock into her belly and let her know I was happy to receive her juices from that gushing.
We have a shower , during which she wanks me off.
When we go back to the kitchen she makes a coffee, and confesses to me that her marriage to my uncle is a sham. She explains that he is not the guy she married and wants more sexual satisfaction than he can give. She openly admits to being in the BDSM community (which peaks my curiosity and cock). I ask her more about it.
She tells me that she is a switch that likes being in control as well as being used. She reveals that she Dommes my uncle, usually fucking his arse (I thought about the toys I found, but would not reveal about that part of my sexual curiosity just yet).
I knew it was getting close to when uncle Dave was close to getting home, so I told her that this would continue, at a mutually agreeable time and date. I also told her that she would stop seeing other men as a slut and it would be to her benefit. I also whisper in her ear that I was what she wanted to make her really happy.
I thank her for the coffee and leave, but not before going upstairs and picking her knickers and bra up. Then returning to the kitchen. I tell her I will enjoy her knickers til I see her again, at which time I would return her bra & knickers, for her to wash, just in case uncle Dave noticed her knickers were not with her bra.
