18 months later.
Joan was holding onto the headboard as I was shagging her from behind on the bed in her granny annex.
"Come in my cunt," she screamed as she reached orgasm.
I came with a roar which seemed to fill the room. We cuddled up after we disentangled from each other, her phone that was sitting on the side then bleeped, she checked her messages and there was one from her husband asking us to keep the noise down, and then a circular from her party leader telling all his MPs that he was resigning the next morning because he had been found out that a company he was MD of, (Which he hadn't declared) was selling 2nd hand fighter planes to a government that had United Nations sanctions against it.
"What a stupid wanker," I said. "I wonder who will be leader next I asked?"
"I might go for it," she said.
"That would work, A new MP, with experience of life outside of Westminster bubble, might appeal to the party's members," I said.
"You are so sweet," she said, and kissed me on the lips. "That bitch Halsey will probably go for it as well," she spat.
"Got any dirt on her?" I asked.
"I like your thinking," she said, "but she is a pious old cow with no vices what so ever."
"Leave it with me, I'll do some digging." I said.
With that she kissed me and got her dressing gown and left to go and sleep in her husband's bed.
The next day Joan and her husband attended a family wedding so I was at loose end.
I rang round a few friends and colleagues and found out some gossip on Eleanor Halsey. It was also my step mother's birthday so I bought a card and some flowers and drove round to the house, she answered the door wearing a white zip up blouse and dark grey slacks, as it was a warm day the cardigan had been dispensed with.
"Happy Birthday Mum," I said as she opened the door, she looked at me despondently and invited me in.
"Your fucking father has fucked off to a fishing competition on my fucking birthday," she spat once we had sat down on the sofa. I reached over and kissed her on the cheek, and held her hand, she sighed and said "Well, now you're here, lets have some fun, where's the rest of my present?" as she slid over and sat right next to me.
I looked confused as she grabbed my cock through my shorts.
"I thought we couldn't anymore," I said as she gently stroked using the end of her fingers.
She took my hand and let me upstairs into her bedroom. She kissed me hard on the lips and I responded, we were soon snogging like teenagers as reached between us and unzipped her blouse and removed it from her slacks, she unbuttoned my shirt and run her hands over my chest; we stood back from each other taking deep breaths, and then grabbed each other again. I pulled her blouse right off, she tore my shirt off, I removed her bra and she started to undo my shorts. She pulled them down and looked excited when she realised I had gone commando, I undid her trousers and pulled her knickers down at the same time. She stepped out of them and we resumed snogging before falling together on her bed, I put my hands between her thighs and she willing opened them wide, she was soaking wet with the anticipation of it all, I crawled onto of her and placed my cock at her entrance, she grabbed it and pushed it in, she grunted as I pushed all the way in and soon we were fucking like rabbits, "Keep going," she said as she came, wrapping her legs around my waist as she did. We continued fucking until I came into her welcoming pussy.
I kissed her on the lips and said "Happy birthday." We stayed in bed all day until the phone rang, it was my dad to stay he would be home in an hour, cue another frenzied bout of fucking in the shower, we were all presentable by the time he got home and apologised profusely, saying he had got the dates mixed up, and mentioned something about giving her some loving, she just smiled and said she was too tired having been busy all day.
After I left she sent me a text saying that we would do that for her birthday and Christmas present every year from now on.
I checked my emails when I got home and some information on Eleanor Halsey had come back, it turns out that Eleanor was not as clean as it seems, despite being married she enjoyed a bit of extra curricular activities with a number of men, and the activities she enjoyed were unusual.
I managed to track down one of the men in question who I got drunk in a bar, one evening. He left his mobile on the table when he went to the toilet to throw up and I found some pictures of Eleanor being fucked by a young man, whilst she was shafting another man up the arse with a huge strap on.
I copied these onto my phone, when I got home I transferred them to my laptop, created an anonymous email account and emailed them to the editors of the big Sunday newspapers, Eleanor resigned as an MP Sunday afternoon claiming family issues that needed to be worked through.
Joan didn't ask if it was me that ruined Eleanor Halsey's career and I didn't tell her but she seemed to know because she let me take her anal cherry Sunday evening.
A couple of weeks later all the nominations for the party leadership were in, there was Joan, a gentleman called Andrew Brown and a lady called Vera Ashworth.
As the 3rd largest party they were never going to win a general election but there was some kudos with being a party leader so they all really went for it. The initial polls showed Andrew was third and a long way behind the 2 ladies; apparently he had a reputation for being over familiar with the ladies at party conventions and they were now going to make him pay.
Vera was 70 years old and seen as the party matriarch. She was a large jolly lady who had been happily married for nearly 50 years; she had 2 grown up children who were now barristers and 5 grand children, she also had a great grand child on the way.
I did some research on Vera and found something odd, it seems that she always went to a book club on a Wednesday evening in her local constituency, this club was for ladies only but gentlemen were seen entering and leaving the at the same time but via the back door only, as her constituency was neat to Joan's I waited outside one night and watched, the rumours were correct, a group of approximately 10 older ladies would enter through the front door of this large house and a similar amount of gentlemen would enter through the back door.
I waited until they left and followed 2 of the men in their car. They pulled up outside a pub and went in for a drink. I went in after them and listened to their conversation as I sat nearby, "That mask really scratches," said one, "yeah, doesn't that large lady really give a good blow job though," said the other and started to laugh.
I reported my findings to Joan who looked thoughtful and decided to sleep on it for a few days. A couple of days later she asked me over to her office in the main house for a chat, her husband was away for a few days and parliament was in recess so we spent most of the time in the constituency. She was sitting at her desk wearing a frilly white blouse which buttoned up to the neck and long black skirt, her matching suit jacket hung on the back of the chair, her shoes were off and she swinging a foot to an fro, I walked her behind her and placed my hands on her shoulder and started to slowly massage them.
"That's nice," she said as she leaned back into me. I leaned over her and kissed her forehead.
I spun her chair round and kneeled in front of her, and lifted her skirt up and stuck my head up he skirt, she opened her legs and pulled my head to her crotch.
"Lick me," She commanded as I pulled the gusset of her knickers to one side and dove straight in, soon she was panting and holding my head in place, she then came with a shriek and held me in place, she pushed my head out from under her skirt and stood up leaving me sitting on the floor.
"As much as I would love to do more, the local party chairman is on his way over, can you take notes please, I also need to ask you a favour," she said as she smoothed down her skirt, just then the doorbell rang and so I answered the door and showed in the gentleman, he waffled on for ages about nothing in particular and then asked for copy of the meeting notes be sent to him. Joan took it all in his stride until she could kick him out of the door an hour later.
As soon as I had closed the front door behind him Joan started to walk up stairs unbuttoning her blouse, she looked turned her head and said "Are you coming?"
