My wife their slut :- based entirely on our sex life

Was it planned? no, did we think it could happen? it was something that had never entered our heads, but once it happened there was no going back….ever.
Penny and I had met through my younger sister and hit it off right away. I won’t be kidding you about tall and beautiful big tits and sexy legs, we were your normal twenty year old’s, Penny 5′ 3″ slim with nice pert tits and tight ass, me 5′ 8″ also slim and a bit bald on top. One thing which was different or at least unusual Penny was a virgin and resolute in the fact that she would remain so until someone slipped a ring on her finger.
I can tell you it was a long two years on the sex side, we never got further than the heavy petting and groping stage, her cunt was exposed to me just twice, the second time I got my tongue in there, but only for seconds. You don’t need me to tell you, but yes we married in a nice church on a nice November day, did it improve our sex life, not a chance. Penny started her period that very morning something that made our first nine months of marriage a complete disaster, so much so I was close to finishing it. The problem was Penny could not relax with sex, penetration was almost impossible. Penny told me years later how patient and kind I’d been, for my part I realised later I should have been a lot firmer maybe even cruel to quell the problem.
We both worked, and I think this helped take us through the storm y times, because we were not in each others pockets all the time. I never thought in my mind of minds that work could be the solution to our problem. Bob an older bloke at work had been my mentor at the company when I started straight from school, really genuine and helpful and a source of a lift to work whenever my bike was off the road. One Friday evening Penny and I walked rounds to the Woodcutter arms our local pub, we plopped ourselves down at a table in the lounge, and there sat Bob, that normal big smile on his face, introductions were made and drinks bought. Penny decided to try my tipple of cider a lot stronger than she expected , two pints later she was shall I say happy. She and Bob getting on like a house on fire.
Penny was dressed quite casual for a sunny summer evening, a cotton print flowing dress two inches above her knee, it had a really low back which meant her sheer bra with invisible straps, and a pair of simple flat black shoes.
Throughout the evening just like work the sexual innuendo was strong, and in particular Bob’s repeated notion that he’d like Penny to turn her backless dress 180 degree’s, just like a women Penny blushed and giggled every time. At the end of the evening the three of us left together, and with Bob’s apartment being en route we got invited in for another drink or two. Penny was now on the wine and after a couple was more than a little pissed and relaxed, and when she excused herself to use the loo, Bob shouted after her not to forget her promise to turn her dress (a promise she had never made except in Bob’s mind).
You can’t imagine the shock for both Bob and I five minutes later, there stood Penny tit’s completely on show, blushing like a school girl, not only had she turned the dress round, but her bra was hanging loosely from her fist and a grin lit up her eyes. At that moment I loved her so much, and I couldn’t believe what I did next, grabbing her wrist I pulled a giggling Penny onto the sofa between Bob and I. He didn’t hesitate hands moving to her tits playing with her hardening nipples…me what else could I do I joined in, and pretty soon we each had a nipple in our lips, and a moaning Penny lay back in full pleasure. Things progressed my hand drifted down to her thigh, I found I was second best, Bob had Penny’s panties pulled to one side his fingers wringing her exposed bullet like clit. Penny gasped when my finger slid along her cunt lips, for the first time I found them damp, no wet, wet and open. One then two fingers entered easily. I looked up to see a grinning Bob, his lips gripping and stretching a rock hard nipple.
After a couple of minutes he was gone, I looked round and there he was sat in a straight backed chair pants gone and his hand wrapped round his engorged cock. Not a word was spoken except by his eyes they screamed bring her to me, I never hesitated. Lifting Penny to her feet, sliding her damp panties down her thighs lifting each foot in turn leaving the panties to fall, Penny not taking her eyes from Bob.
She half walked half stumbled towards Bob, it was like we were in a dream I was helping Penny mount another man my wife of less than a year was going to get fucked by to her a stranger. She spread her legs over the chair lowering herself Bob guiding his cock between her cunt lips, me kneeling watching her lips being stretched cock entering easily, her bumhole on full view twitching with her excitement. Bob gripped her ass cheek ramming her like a man possessed his cock pistoning in and out of my young wife cunt stretched and swollen , Penny came quickly her fluids pouring down his cock, then I swear she came again at the same time as Bob exploded into her gasping for air.
Between us we lifted her to her feet, only for me to then instantly lower her to the carpet entering her hot cum filled pussy in one move, her legs wrapped round my waist pulling me in. Again and again she just kept up mini orgasms, was it me or the excitement night pumping her with her second dick of the night. I did notice her eyes kept drifting to Bob, once again a hardening cock in his hand watching the debauched fucking before him.I knew I wouldn’t last like Bob before me I discharged jet after jet of spunk into my darling wife flooding her already sopping cunt.
I couldn’t believe as I rolled away, Bob was moving Penny into the doggy position, she didn’t object although I knew she was tired. I watched Bob open her cunt lips spreading them as if showing me how swollen red and wet she was with spunk oozing down her thighs. He entered her for the second time that night, and for the first time for a while he broke the silence. A simple thank you left his lips, meant I think for both of us, but directed at me. It’s hard to believe now but I think I thanked him back.
He lasted a little longer second time round, but I’m sure not more than ten minutes. Penny continued her small orgasms throughout, something I would become accustomed to over the years.
Penny was exhausted and wanted to go home, I think she was feeling a little guilty. We dressed her best we could turning her dress and cleaning her with tissue, her bra and panties left with Bob. Within fifteen minutes we were home, and a further ten minutes I was fucking Penny yet again, she was begging for more and more. She said something that night which stayed with me forever. Has she had watched Bob playing with himself waiting his turn, she had wished the room had been full of Bob’s.
Weeks past, sex as you can imagine had improved beyond belief and we were practising things Penny would never had gone for. Mainly oral sex my cock looked great between her lips although swallowing spunk was not on her agenda.
Then one Friday evening we were sat relaxing after work, Penny quite timidly mentioned we should go and eat at the pub to save cooking. I agreed quickly I was hopefully reading Penny’s mind, our evening with Bob had never been discussed but I guessed that like me Penny had given it lots of thought.
We were not disappointed, when we entered the bar there sat a smiling Bob. We only had one drink that night before disappearing to his apartment. So started an eleven month liaison, Bob and I fucked her in every room in every position up against the wall over and in the bath, on top, underneath and doggy , watching her swallow Bob’s cock her head hanging over the bed while I fucked her hard was special. The best thing I remember we taught her to talk dirty, fuck, cock, cunt and blow job slipped easily from her lips, but even better was one evening, two cocks in front of her face shooting ropes of cum into her eager mouth and across her face her chasing the spunk with her tongue. We called them no knickers Friday, because if she wore them Bob kept them for his collection.
Why only eleven months, three reasons 1. I got a big promotion taking me miles down country, 2, Penny wanted to start a family, 3, Bob found love with a friend of Penny and they got married. He promised and given who he married I guess he kept our little secret….
