Sam and Lisa got on very well, I began to feel jealous.  Before we met, Sam had dabbled with lesbianism.  More than dabbled, she said that she was fully into it.  She often stoked my passions by telling me about the things she did with her female lovers.  Why then had she chosen me?

"You know why," she said, reaching for my cock.  "This is why.  I like cunt, but I like cock more."

She went on to say that like me, she had never strayed from the marital path and had no plans to do so.

She would have been justified in taking a lover, a young stud with a permanently hard cock, someone vigorous enough to match her, orgasm for orgasm.  Preferably with me watching.  She was speaking;

"Everthing I need or want, is you."

"But suppose I was tempted," I said, she is a very desirable woman."

Sam changed the subject, slightly;

"She can hear us when we fuck."

I wasn't surprised, Sam is a noisy comer.

"She masturbates as we fuck."

Went on Sam.

"Wow," I breathed.  "That, I would like to see."

Sam laughed.

"Her words exactly, she asked me if your pubes were ginger, to match your head hair.  I said yes, she said that she would like to see."

My suspicions that Sam had somehow planned this, gai ed strength.  Where was this leading?

"She hasn't had any since before her divorce.  Cock that is," said Sam.  "Six months without, poor girl must be desperate."

If a woman as good looking as Lisa wanted fucking, surely there would be plenty on offer?  I said as much.  Sam's next words were heart stopping;

"I'd like it to be you.  So would she."

When I regained the power of speech, I said;

"You're giving me to her, really?  What would you get out of it?"

"I would be lending you, not giving you, "she said."  And I would be doing a favour for a friend. Don't tell me that you would not like to fuck her, I've seen the way you look at her."

"It's a dangerous path."

"But an exciting one.  Go to her tomorrow, give her the fucking she needs."

It was a Friday night, we were in bed, we had just fucked but my cock was like a flagpole.

"Now fuck me again," husked Sam.  "Imagine that you're fucking her."

Afterwards, even after two vigorous fucks, I could not sleep.  Sam was snoring gently beside me.  I had a mighty hard on, I could not get the idea of Lisa, masturbating just a few feet from where I was, out of my head.  Perhaps even fucking herself with a massive dildo.  I wanked myself off thinking about it.

Sam had to go into work the next day, leaving me alone with Lisa.  The tension was palpable.  Eventually, I said;

"Are you sure about this?  It could end in disaster."

"Don't you want me?"

She replied

"Very much so,"  I said.  "But Sam and I have something special, I don't want to risk that."

"I don't want to threaten that.  If it doesn't work out, I will leave immediately.  Sam loves you more than life, she's a very generous woman, this was her suggestion, you would not be cheating."

"It's still infidelity though."

"Do you wank yourself off?"

I wasn't expecting that one.  I muttered yes.

"Do you always think of Sam as you do it?"

I had to admit that I didn't.

"Have you thought of me as you wank?"

I muttered yes.

"Virtual infidelity," she said.  "We all have our fantasies.  Sam wants, it, I want it, you have the casting vote.  Do you want it?  Or would you prefer a wank?"

We ate out, as we often did on Saturdays.  And as usual we drew a lot of attention.  One man, two very attractive women.  Very different in appearance, Lisa blonde and slim, Sam brunette and well upholstered.  There was not much conversation between us.  When we got home, Lisa went straight up to her room.  Shortly afterwards, we heard her shower running.

"She's getting ready for you," said Sam.  "Go on, a quick shower, then go to her.  With my blessing."

Wearing only a dressing gown, I tapped gently on Lisa's door and was told to enter.  Lisa was in bed, sitting up with the duvet pulled up to her neck.  I said;

"Are you sure about this?"

She let the duvet drop, revealing her small, firm tits.  Her nipples were large, dark pink and fully erect.  She flicked the duvet back in invitation.  I moved to the side of the bed and removed my dressing gown, my cock was as erect as her nipples, her eyes went straight to it.  I slipped into bed beside her and kissed her gently on the mouth, cupping a tit as I did so.  She was very tense, but relaxed as the kiss intensified.  She put her arms around me.

I had a plan.  Sometimes with Sam, our desire for each other is so great that we will pull at each others clothes to uncover only what is needed for instant  penetration,  no foreplay, just an urgent coupling.  Usually safe in the knowledge that it was a pressure relief fuck, a prelude to the second round, which would be slow burn.  Re-exploring each others bodies slowly and thoroughly, knowing that penetration and ejaculation really will be the climax.  I will not feed my cock into her until she has had at least one orgasm.

This was my plan with Lisa.  Slow burn.  I caressed and kissed her tits, sucking each nipple in turn, comparison with her willowy body and that of my wife unavoidable, realising that I could have the best of both.  Slowly, I kissed my way towards my final destination.  Her mound was smooth and hairless, her sex lips moist and parted in anticipation.  She jumped as my tongue touched the sensitive flesh, then groaned as I licked upwards  collecting her nectar.

Her clitoris was large and prominent, almost as though it was reaching for my tongue.  Another unavoidable comparison,  Sam's clit is tiny and hidden, requiring a deliciously search to find it.  Lisa had been passive during my manual and oral exploration, but now she placed her hands firmly behind my head and raised her hips for firmer contact.  So she was a lover of oral.  Good.  So am I.

She came quickly, shuddering and gasping, pushing my face into her liquid centre.  It was time for the finale.  I pulled myself away and quickly scrambled into position.  At this point, Sam would have been scrabbling for my cock, anxious to be filled.  Lisa remained passive, allowing me to find her entrance alone.  I rarely miss.

She groaned as my rigid meat filled her, I entered in a single firm thrust, ball deep.  Only then did she wrap her arms and legs around me.  I fucked her hard and fast, I had no choice, any attempt to delay my own climax would have failed, I just went for it.  Lisa became only the second woman I have ever fucked without wearing a condom

One of these days, I will count the spurts.  This was certainly one of my better efforts, I seemed to be pumping for ages.  Eventually it stopped and I was able to remain still inside her, my still hard cock soaking in our combined juices.  Lisa did not relax her grip, I could feel her body jerking.  A second climax perhaps?  Only when my cock softened inside her did she unwrap me.  I rolled to one side, she reached for tissues to clean herself up.

She thanked me, adding her apologies for having me do all the work, she was nervous, next time it would be better.

"That is," she said.  "If you want me again."

I kissed her and assured her that it had been a pleasure, and yes, I hoped there would be many more times.

"Go back to your wife," she said.  "And thank her for allowing this to happen.  I really needed it."

I put my dressing gown back on.  Goodness knows why, I had nothing left to hide from either Lisa or Sam, and as far as I was aware, there were only the three of us.  Back in my own bedroom, Sam flicked back the duvet  as Lisa had done.

"Mission accomplished?"

She said.  I nodded sheepishly. 

"I hope she's left some for me," she said.  "My cunt's on fire."

"Ask me again in about ten minutes."

I replied.  But she was having none of it, she ducked under the duvet and took my limp cock into her mouth.  I winced.  Not because it  was tender, but because it had just been inside Lisa.  But Sam knew exactly what she was doing.  If she had been telling the truth for all these years, the only cunt that she had tasted had been her own, now she was tasting Lisa's.  Now I  was certain.  Lisa being in our house was no accident.

But I'm not one to baulk at my cock being sucked, I laid back and thought of England.  Not really, what I was thinking was what Sam had planned to happen next.  She brought me very close to climax, she can tell precisely when to stop, unless she fancies a creamy mouthful.

"Now?"

She said, looking up at me.  I nodded my readiness.  Sam turned round and placed herself on all fours, head down, arse up.  No words were needed.  Her gaping cunt shone like a jewel.  I fed my rescusitated boner into her more familiar socket.  I like doggy, so does Sam, I love the way her fine tits swing in time to my thrusts and I like to hang onto them as I pump her.  I did this now, transferring one hand to the base of her belly when I felt my come coming, finding the stiff, oily bead of her clit with my fingers and strumming it until she came.  Then I let go with my second load of the day.

The next thing I remember, was waking up.  It was daylight and I had my usual morning glory.  But Sam was not by my side.  A delicious smell of coffee was drifting up fro the kitchen.  I pulled on some clothes and still tousled from sleep, followed my nose.  Sam and Lisa were sitting at the breakfast bar.

"Morning Sleepyhead," said Sam.  "Coffee?"

I nodded.

"We were just comparing notes."

She said.

"How did I do?"

I asked.  They looked at each other and grinned.  Sam said;

"Eight out of ten for effort, room for improvement."

"So I'm to be replaced?"

"Oh no, we'll retrain you."

"Can I have some breakfast then?  I need to keep my strength up."

I felt awkward during the day, they both seemed very relaxed about our strange relationship.  We went out for Sunday lunch, feeling slightly mellower afterwards, I raised the subject of how this was going to work, to quote a well known and much missed woman;

"Having a third person in our marriage."

Was I expected to service one 'wife' on even days and the other on odd days, or were we talking three in a bed.  Sam at last revealed her master plan;

"We will all share each other.  I have always fancied both men and women, Lisa has told me that she feels the same way.  We fancy each other."

I expected as much.  I said;

"You haven't already started without me then?"

"No," chipped in Lisa.  "We would like not only your approval, but your participation.  Bisexual threesomes."

I had little choice but to agree, at least to try it.  I expected it to be short lived and I would be living the dream, a choice of fuckable women, and live lesbian sex shows when I could no longer get it up.  I nodded and said;

"We'll give it a try."

I had the grandfather of all hard ons.  It had not gone un-noticed. 

"Bed."

Said Sam.  Ten minutes later, three in our bed, all naked.  They worked on my cock, sharing the task, sharing a kiss as my cock was passed from one mouth to the other.  I let them do the work and lay back with my hands behind my head.  Lisa got the reward, a freshly produced helping of my spunk.  She shared it with Sam, passing it from mouth to mouth like they had done with the dispenser.  Then they started on each other.

Slowly and gently at first.  If they were to be believed,  it was their first time together.  My presence was soon forgotten as their passions arose.  If it had truly been fifteen years, Sam seemed to have forgotten nothing.  Lisa too, seemed to know what Sam wanted.  First they played with each other, kissing and fondling.  Lisa on her back, Sam on her side.  Then Sam lay on top as they kissed.  Mouth crushed against mouth tit crushed against tit.

Lisa rolled Sam onto her back and straddled her, head to toe.  She leaned forward to kiss and lick Sam's cunt, Sam's tongue sought out Lisa's lower mouth and they performed a steamy lesbian sixty- nine.  Neither of them came.  Lisa then turned and straddled Sam's thigh, pushing forwards so that they kissed cunts.  Scissoring.  Exquisite!

I found it mesmerising.  This was so much better than porn, this was real.  All the sights and sounds, plus the aroma of lust.  And I had fucked both of these women and would do so again  over and over.  They seemed to orgasm in synch  or very close to it.  A noisy squealing symphony of shared lust.  Lisa rolled onto her back, breathing hard, tits rising and falling.

"Fuck her," growled Sam.  "Fuck Lisa."

I joined them on the bed, cock wagging like a dog's tail.  But it was Lisa who was about to get the bone.  Sam guided my cock to Lisa's gape.  Unnecessary, but very horny.  I sheathed my rampant cock in one thrust, Lisa cried out as I filled her.  This was something that no lesbian relationship ship could match, a real live cock.  I had found my place in the threesome, I was their human dildo.

It was a spectacular fuck, even by Sam and my standards.  Lisa seemed to be orgasmic throughout, completely out of it.  Encouragement came from my wife;

"Harder, fuck her harder.  Give it to her, give your cock, fill her cunt with your spunk."

She knew full well how much it turned me on for her to 'talk dirty'.  She was masturbating furiously, her voice becoming more shrill as she rapidly reached her peak.  When I came, if felt like my cock was exploding.  I roared as I came, releasing a flood of spunt into Lisa's clasping cunt.

I pulled out still hard, rocked back on my heels and surveyed my work.  Thick, white spunk was slowly oozing from Lisa's plundered hole  like lava flowing from volcano.  Sam pushed me aside and lowered her head to the source of the flow, lapping at the mixture like a kitten laps at cream.  It was a heart stopping moment, my wife doing what I had been promising myself for years.  My cock was rigid, Sam's gaping cunt beckoning.  I slid straight into the familiar hole.

I surprised myself with the speed of my second coming, my first threesome had stoked my libido to teenage levels.  I actually felt that I could go again straight away.  Where should I shoot load number three?  Now it was Sam's cunt that was leaking my prescious fluid, should I push it back in with my still hard cock?  Or assault her other hole?  Or perhaps at last, perform the cleanup that I had been putting off?

My procrastination again cheated me.  Sam walked on her knees, my cum hanging in silver threads from her cunt lips, and pressed herself against Lisa's mouth.  Damn!  Next time.  Perhaps.
