I was quite pleased thinking I'd made some progress with Mum and Dad and getting them to understand that I wasn't at all phased by their, shall we say, different private lifestyle. They were still a bit reserved and would never raise the issue of our relationship still less initiate any sex.
However Dad would give me a demure thank you when I offered him my panties at the end of the day. Mum would wear plunging tops because she knew I liked looking at her cleavage and would occasionally open her legs while sitting watching the TV so I could see up her skirt.
What I wanted more than anything, though, was to be invited to one of their meetings. I imagined all sorts of things going on and it only served to get me hot and bothered. I knew one was coming up as I had cracked their code on the wall calendar in the kitchen. MTG JK & MRA didn't take much cracking it has to be said.
My hints became less subtle as the date approached. In the end I had to ask bluntly.
"Mum, do you think I'd be allowed to come to one of your meetings?"
Mum as usual got all flustered, well she would especially as I was tweaking one her nipples when I asked.
"I don't know, Sarah. They're rather sensitive about who comes along, you know."
I slipped my hand inside her blouse and bra and squeeze her big fat tit in the palm of my hand.
"Oooh, Sarah, don't. Your Dad will be home soon. What will he think?" Scolded Mum.
"Pleeease, Mum. Will you at least ask? And I should think Dad will think the same as you did when you watched me stroke him off into my panties, Mum." I added for good measure unbuttoning her blouse.
"Sarah, you used to be such a nice innocent little girl." She said but offered no resistance as I brought both her tits out into the open.
I pushed my hand up her skirt and stroked her through her knickers.
"Go on Mum, I'm sure they won't mind having some fresh blood come in and I'll be very discreet." My fingers slipped around the edge of Mum's knickers and gently fondled her lips. She was already wet.
Mum's breathing was becoming a bit laboured as I teased her pussy lips. I let her enjoy my playing and bent my head down so I could suck on her large erect nipples. She moaned and slipped her hand around the back of my head, pulling me in close as my fingers pushed between her lips and slid around in her oils.
"Pleeease, Mum." I persisted, looking up at her.
"Oh, Sarah, that's so nice but Dad will be here any minute." Her voice a little moany. "I'll have a word with Dad but I can't promise anything. Now stop, I've got to get Dad's tea ready."
She didn't sound very convincing about me stopping but I knew I'd won. I pushed two fingers inside her and let my thumb press against her clit. She leaned back against the worktop and let me take her to orgasm.
The next evening Mum and Dad called me into the living room and sat me down. I felt like I was going to be interviewed. Dad started but looked ever so embarrassed, poor man.
"Sarah, Mum told me you asked if you could be invited to our next, erm, meeting."
I knew it was taking all his courage to talk about this.
"I was very set against it. You are after all our little girl and the thought of being in a situation where anyone could, um, could, er ..."
"Fuck me, Dad?" I interrupted. He turned bright red.
"Um, yes. I suppose." He managed. "And also while it is bad enough that I, we, that is your Mum and me, um, have had, erm .."
"Fucked me?" I added helpfully.
"Um, yes. While we have had relations it is in the privacy of our own home and we know we can keep it secret."
"Well how about we all pretend it hasn't happened and I'm just there because you know I enjoy sex, you know, being fucked, and you, being very open and modern parents, want to let me enjoy myself." I suggested.
Mum and Dad looked at each other in that 'we're not going to win this no matter what' sort of way then turned back to me. Dad spoke first.
"Okay, Sarah. I'll have a word with Jack and Moira and see what they say. We can't promise anything."
"Oh, thank you Daddy." I trilled as I jumped in his lap and gave him a big hug and a kiss. "I'll be very good, I proimise."
The day approached and we were all in the car together and driving to Jack and Moira's, a couple I'd never even heard Mum and Dad mention let alone meet. Dad had loaded a holdall in the boot and I had been given a thorough talking to telling me the etiquette involved with these meetings.
The car pulled up a long drive to a large country house deep in the countryside. There were already several cars parked in front of the house and I could see an older couple walking up the steps to the front door. It wasn't until we parked and got out of the car that I started to feel a bit nervous.
Mum put her arm around me and told me that they had to go and get changed. I must have looked mortified but she assured me that she'd leave me with Julie and Dan, the couple who had helped me start the relationship with my parents, who would look after me and show me around in the meantime.
I wasn't overjoyed by the arrangement but I knew I was there on sufferance so politely agreed.
We all walked up the steps to the front door and into a lobby area with plush carpet and dark wood panels. There was some serious money involved here.
A couple in their 50s were standing by a marble topped table and approached as we entered. The man shook hands with Dad and kissed Mum on the lips and the woman kissed both Mum and Dad. They then turned to look at me expectantly.
"This is our daughter, Sarah." Announced Dad. "Sarah, this is Jack and Moira."
Jack was quite a tall man with tight curly hair that had greyed around the edges. He was slim and quite fit and wearing an immaculate suit. His wife Moira, around the same age, had quite bouffant hair and wearing a dress that hugged her slim waist and showed off her rounded bum and large breasts. Her makeup was subtle but her lips bright red with lipstick.
Jack took my hand then pulled me in and kissed me on both cheeks while his other hand gently stroked my arm. Moira smiled benevolently and air kissed me on my cheeks too. Her hand hovered close to my waist as she lent in to me.
"Very pleased to meet you, Sarah." Said Jack in a smooth welcoming voice. "I'm sure it's very intimidating for your first time but it will be fine. Just remember you don't have to do anything, if you just want to wander around and acclimatise, as it were, you are most welcome."
"It was very kind of you to allow me to be invited." I replied. "I'm sure after all the trouble I've caused you will find me a very active visitor."
I held his gaze and gave him my best smile. I had a strange suspicion we'd be an awful lot closer by the end of the evening.
We passed through and archway and down a corridor that opened out into a large lounge. There must have been thirty people gathered, drinking and chatting, There was a bar at one end with a few people sitting on bar stools and I immediately recognised Dan and Julie.
