Life returned to a kind of normality.  We fucked, but we didn't make love.  It was relief sex, better than wanking, but clinical.  Ther was still no kissing.  Actually, that's not true, she would let me kiss her cunt, but not her mouth.  She wouldn't suck my cock.

It was about a month since I had made the biggest mistake of my life, fucking Lisa, when Gemma came home excited.

“It's all arranged,” she said.  “On Saturday, somebody’s coming round to fuck me.  In our bed, you will watch.”

I was gobsmacked.  She would say nothing else.  Saturday arrived, we had an early dinner and she disapeared upstairs, saying;

“He’s due at eight, let him in and bring him to me.  Whatever happens, you have to watch, you will be a spectator, you are not allowed to wank.  Agreed?”

I nodded.  He introduced himself as Mathew.  He was tall, fit, polite and could have been a film star.  He was also black.  Well, brown.  He had been fully briefed about what was to happen.  What was to happen, was that he would fuck my wife senseless while I watched.

I led him upstairs.  Gemma had stripped off the duvet, but had arranged several pillows.  There was a chair at one side of the bed.  She was wearing a silk kimono.  Matthew asked for the bathroom and disapeared.  He came out naked.  He was certainly fit, athlete fit, not muscle-man. His cock was half hard.  I had expected it to be a monster, but it looked about average.

Gemma undid the kimono and threw it aside.  She wore high heels and stockings supported by a suspender belt.  A thong, but no bra.  In spite of my nerves, my cock hardened.  Matthew’s remained heavy but limp.  Gemma put her arms around his neck and pulled him down into a kiss, a long, tongue fencing, passionate kiss.  She had not let me kiss her since that night.  My erection vanished.

When the kiss broke, Matthew's cock was showing interest.  Unlike me, he was circumcised.  His cock and balls looked darker than the rest of him.  Gemma went to her knees, and fondled his prong, rubbing it against her face.  By now it was fully erect.  She kissed the tip, then licked her way down to his balls and back again before taking it into her mouth.

Gemma is an expert cocksucker, she can keep me on the boil for ages, stopping when I am about to spurt, then starting again, building pressure and volume for wherever she wants me to shoot it.  She did this with Matthew until he had to pull her off.  She lay on the bed, one knee raised.  Matthew kissed her again, lots of kisses, passionate ones, intended to hurt me.

As they kissed, his hands roamed her body, caressing.  He kissed his way down, spending a lot of time on her tits.  She lifted her backside so that he could remove the damp thong.  He kissed her inner thighs and her buttocks, her legs were raised and parted allowing full access, her hips pushed towards him.  She cried out when he placed a kiss on her cunt, then he was sucking and licking.  She came almost instantly.

Matthew scrambled up and positioned himself for entry, his cock drawn like magnetism to her gaping hole.  She groaned as he entered, filling her.  Gemma's arms and legs wrapped him, he fucked her with deep strokes, gradually increasing tempo.  Gemma came for a second time, Matthew groaned as he shot his spunk deep inside her.

Matthew stayed inside her, supporting his weight on his knees and elbows  then rolled onto his back still inside her, taking Gemma with him.  He resumed his thrusts.  Gemma's tits bounced as he drove up into her, until he took one in eack hand, stilling them.   Gemma then leaned forward to kiss him and he moved his hands to her buttocks, still pumping her.

Matthew's second coming took longer than his first.  Gemma did not come with him.  Afterwards, she lay on top of him, both recovering, until his cock softened and slipped out.  I had not used the chair, preferring to move quietly round.  Forced to observe, I decided to make the most of this live sex show, starring the woman I loved.

My cock had been rigid against my belly for most of the time.  I was desperate for release, but had been I instructed not to wank by Gemma, she clearly had her reasons.  I moved from the side to a position three-quarters on, just in time to see the backwash of Matthew's spunk from her dilated cunt.  I had a sudden urge to lick it.  I almost came anyway.

Any such thoughts disappeared as Matthew rolled aside.  They lay side by side, chests heaving.  Gemma turned to him and kissed him again, her hand finding his soft, wet cock.  It stirred as her fingers closed around it.  She moved down and took the spunky, cunty, one-eyed black mamba into her mouth.  She likes to feel my cock go from soft to hard in her mouth.  Matthews responded just as mine does.

After a few minutes of her special massage, he said something that I missed.  She released him and got on all fours, arse upwards, her still gaping cunt glistening with their mixture.  Matthew positioned himself behind her and fed his resurrected cock into her.

This third and last fuck was frantic, animal, a race to the finish.  This time, Matthew cried out as though he was in pain as his last dregs spat into Gemma.  He slipped out immediately, leaving another little flood of spunk to trickle from Gemma's plundered hole.

I had just watched my wife fucked three times by another man.

“I'm done.”

He said simply, and went into the bathroom.  Gemma rolled on to her back panting, shining with perspiration and fuck-fluids, looking absolutely debauched but beautiful.  She parted her thighs revealing once again her filled treasure.

“More,” she said.  “I want more.”

Did she mean me?  I had more, plenty more.  I tore at my clothes, removing enough to free my straining cock and without any preliminaries, sank it into her sodden cunt, knowing that the wetness was another man's spunk.  It felt wonderful.  If Matthew's fuck was frantic, how could mine be described?  Unstoppable?  All too soon, I was blasting a tsunami of spunk into Gemma's slack, wet and very welcoming cunt.  She came with me, screaming.

I rolled off, gasping for breath.  Matthew was at the bathroom door, fully dressed.

“Shall I let myself out?”

He said, triggering peals of laughter.  He let himself out.

I turned to Gemma and said;

“Does that make us even?”

“I think so,” she replied. “I imagine that you're not quite done though?”

I wasn't.  She mounted me and fucked me again in cowgirl, producing an ejaculation almost as big as my first.

I must have fallen asleep, when I awoke we were covered by the duvet.  We were in spoons.  It was seven o'clock.  I had an erection.  I felt for gemmas cunt, as expected, wet.  I pushed inside her.  A few gentle strokes and she pushed back, joining me for a delicious pre-breakfast fuck.  I came, she didn't.  She turned and kissed me.

“I like your alarm clock.”

She said.

It was not until after our evening meal, curled up on the sofa with the last of the wine, that we spoke about last night's events.

“Where did you find Matthew?”

“You will never know.”

“Did you enjoy it?”

“I did.  I hadn't to expected to, I did it to punish you.  Sorry.  But yes, I enjoyed it, I was turned on by your presence.  I think perhaps I enjoyed being watched.  And when you fucked me still wet from him, I thought that I would die of pleasure.  What were you're feelings.”

“I was dreading it, but once it started, I was enthralled.  I have never watched a woman being fucked, other than on porn.  This was not only real, but you were the star.  It made me want you even more.”

“So do you think that we should do it again?  This time with a couple?”
