 Now whatever I'd thought about sex with other people before we got into it
I can't really remember but even when we began to plan it I don't think I
contemplated it becoming standard practice but it very quickly did.  My
husband Jack, who drove this, bought me a dress and shoes and two weeks
after I'd agreed I had sex with a stranger.  It was fun if a little rushed
but before I could blink I was at it again.

   In truth I'd taken very little persuasion and went at it with swift
enthusiasm which rather confused me because I felt no guilt at all, before
during or after.  We stopped to take stock after the second time but of
course we both wanted it and I happily went out again twice more over the
next two months.

   I have to admit I was feeling so very different and really sexual so
enjoyed it although I was still mystified about Jack's attitude to this: He
kept telling me how he loved seeing me with these other men and he actually
made three homemade videos of me.  Then one night he suggested that perhaps
rather than taking `pot luck' he would find someone different for me to
try, if I was happy for him to choose.  I happily agreed since while it was
fun picking men up there were several elements I didn't like; firstly there
was the risk that the guy might be weird (in bed or a stalker or
something), secondly I might be seen by someone I knew and that would have
been awful and thirdly at times I just wanted sex not two hours of will-I
won't-I.

   Three weeks later one Saturday evening a colossal black man appeared at
our door and Jack let him in then turned me over to the man (I was dressed
for sex in one of my short dresses and stockings) telling him with a big
grin I would slut for him all night!  He was not just black but the biggest
man I'd ever seem and by that I mean huge, fat huge.

   The man was called Moses and I'm ashamed to say his fat cock gave me
climaxes like never before.  Like I said he was enormous; fat and also over
six five but despite his obesity I enjoyed lying with him as his massive
frame covered me.  It's hard to explain but his huge body had a strange
effect on me pushing me to climaxes faster than anyone else.  His sweat;
the abundance and smell, simply fueled my perverse desire for him and what
might have been an unpleasant experience was actually very powerful.  Jack
still laughed at me the next morning, after the guy left, as I lay
exhausted in our bed saturated in our combined sweat, telling me I looked
like I'd been under the shower.

   When Moses appeared the next Friday I was completely baffled there had
been no mention of it and besides we'd already agreed never to see a man
more than once to avoid complications.  Yet here he was asking if I would
spend the night with him at his place!  I asked Jack if he really, really
wanted me to go but he just shrugged which I found totally confusing
although he wouldn't have let Moses ask if he didn't want me to do this.  I
didn't, so I waited for an explanation.

   Christ this was weird!  I gave Jack a cold stare, it was ridiculous,
since the sex was all about a shared experience; the stranger first then
prolonged and powerful sex with Jack after.  I looked at my husband but he
simply stood silently not making any sign he even cared about my feelings
regarding being with this stranger for a second time.  I waited and waited
then when nothing came I got angry: "Fine!" I announced, taking Moses by
the arm.  "Then take me home!" I gave Jack one last chance but he didn't
move so we left.  Fuck!  He was going to let this happen!

   I was nervous as hell and unhappy but sex with Moses was deep and
intense so when he made love with me, for an hour, I just went with it.  I
can't pretend I didn't enjoy it a lot and worse the next morning when he
was more dominant I let myself go: He took me on all fours (a first for me)
holding my hair and getting me to tell him how much I liked being used like
an animal then later lying stomach down over his kitchen island telling him
how good it was being his little slut.  Whorish, nasty sex which was new
for me but I enjoyed it more than I would have ever believed.

   I finally returned to Jack after lunch completely stretched by Moses and
a little sore.  The stupid part of this is that Jack was really sulky when
I came home especially when Moses gave me a kiss goodbye.  Then when he had
sex with me and found me looser than before he got really angry and
suddenly shouted at me called me a tramp and a whore.  I was really, really
upset and burst into tears pointing out that I'd been with other men before
for him so why was this different but he yelled at me stating that he knew
the truth and I was nothing but a black cock whore!

   Where had this come from?  I shouted back that he'd contacted the guy in
the first place and encouraged me to sleep with him but Jack shook his head
and spat back that he'd only agreed to Moses asking me out on Friday
because the guy had taunted him!

   "What the hell do you mean?" I asked still sobbing.  Jack gave me a cold
look then in a clipped tone stated that Moses had called him on Friday
evening just before I got home from work and asked if his wife (me) had
suggested another meeting.  When Jack explained he'd told the man no, Moses
laughed and called him a liar because after last weekend he said he knew I
was black cock obsessed and would beg for more.  Jack added that he told
Moses angrily that was simply bull-shit but Moses had goaded him telling
him to put his money where his mouth was; stating that there was no doubt
given the chance I'd willing fuck him (Moses) again.

   Jack told me that he'd assured Moses that was delusional crap so the guy
then bragged that it was true and that a wager would prove it; Moses told
him he had a grand to offer Jack if he lost against my pussy if he won.  He
then added that he'd jump in the car now and come over and present me with
the chance to screw him again.

   Jack added that Moses suggested that if I said yes then Jack had to
allow me to go with him.  Jack had replied that there was no chance of me
agreeing.  Moses had responded; that in which case there wasn't a problem
with Jack agreeing to the bet then!  They'd argued about this but Jack
admitted Moses was so cocky about it in the end he got angry and agreed. 
Moses then got my husband to concede that if Jack was in the slightest bit
negative then he'd have lost the bet anyway and if I didn't then go with
Moses he'd owe a grand to Moses.

   My husband then added that Moses went quiet and pointed out that he was
risking a grand and all he (Jack) had to lose was me for another night
which given we'd already been together wasn't really fair, so it would only
be right to allow him to maybe see me a couple of Fridays if he won the
bet. Jack added they'd had another argument so Moses again pointed out that
Jack was just chicken and knew I really wanted to be with him (Moses). 
That was enough Jack said, so in the end he agreed to it all.

   "But that was stupid!" I yelled.  "Firstly all you needed to do was tell
me and I'd have told him to get stuffed!"

   I was furious as he basically bet my body for a thousand pounds. 
"Anyway what's all this about Fridays?  Are you mad?  Do you really want
him fucking me every week?  And what does a couple mean?" I yelled: "Once,
twice or fucking six?!!"

   "You obviously enjoyed it though!" He sneered.  "I didn't think for one
second I needed to tell you!  But you jumped at the chance to let that fat
slob fuck you!  He's right isn't he?  You love fucking him!  Admit it you
loved it didn't you!"

   I looked at him coldly.  "You set this up and I went along with it for
you, just for you.  Sure it was fun and I enjoyed the sex but it was always
for you.  I didn't want to sleep with that guy but you insisted and when he
turned out to be not as bad as I feared I was relieved but that was all. 
Then he suddenly turns up again against all we'd agreed and asks me over
and it was clear you knew he was going to ask me, so what was I to think?
Well?" I pressed.  "Like before, I assumed you wanted me to say yes, why
set it up otherwise?  So after getting not a single hint from you I very
reluctantly did." Jack shook his head but fell silent suddenly realising it
was true.

   "So what you're saying is that Fucking Moses is expecting to visit me
again this Friday?" Jack was still silent.  "Oh, fuck you Jack!  What were
you playing at?" I stated angrily.

   Jack looked embarrassed.  "Well I didn't think he would win ..."

   "That's fucking ridiculous!" I was now furious.  "Jack I'm trying to get
this clear in my head.  Did you really want to win the bet or was it
something you actually wanted to lose?  I mean if you'd told me..."

   "No!  Of course I didn't want to lose!  I just misunderstood how it
would go down."

   "How exactly?"

   "I didn't think it through!  I thought he'd turn up and you'd tell him
to go to hell.  But I hadn't thought about you looking to me to tell you
what to do which I'd agreed with Moses not to."

   "You arse!" I was crying again now.  "I certainly don't want to see him
again!" I paused.  "You didn't give him any money did you?"

   "No!"

   "Good because he can go to Hell.  And you can for that matter!"

   I made Jack sleep in the spare room that night but come Sunday I'd
relented as I felt a little guilty about my sexual tryst Friday into
Saturday which was a lot nastier than I'd care to admit to my husband. 
There was something amiss Wednesday evening which Jack avoided discussing
over dinner but that night when we were in bed he mentioned Moses coming
over again and I told him that it wasn't going to happen.  That was when he
became quiet again and I knew something was up.

   "Tell me Jack!  If it's another bet you can both go fuck yourselves, I'm
not doing it!"

   "No we haven't bet." He replied defensively.

   "There is a `but', I can tell!"

   It's just that Moses is being very insistent."

   "Insistent!  He can insist all he likes I don't care..." The look on
Jack's face stopped me.  "What's up?  Come on Jack something's wrong!"

   "Moses has copies of your videos."

   I was speechless for ages then asked in a horse whisper; "You gave them
to him?"

   "When I got in touch with him on the internet he asked for pictures only
after a few emails it seemed ok to send him copies."

   "Even the one of me alone?" God I hoped not.

   "Yes."

   "Oh Jack!"

   After my third extra-marital encounter Jack and I fooled around one
evening and I dressed in some sexy clothes then sat in front room while
Jack videoed me.  It was a very, very erotic and nasty shoot.  I sat facing
the camera as I talked about the three men I'd been with and how much of a
whore I'd become.  I was very excited so really got carried away: I played
with myself on camera and I even made up stories of me with different men;
fantasy about a public sex act and even a gangbang!  That was the evening
I'd talked about having nasty sex with a really big fat black man.  This
was of course just my lust emerging before I came very noisily off screen.

   "Oh my God Jack!  I'm so clearly recognisable in it and...  and I was
so..."

   "...explicit..."

   "But I said those awful, ridiculous things about myself and...  and...
Oh my God!  He's threatening blackmail?"

   "Well...  I guess."

   "Oh my God!  Jack!  I was just so awful in that video.  I identified
myself completely and said the most dreadful, dreadful things!"

   "I'm sorry I really am.  I didn't think he would be such a bastard!" I
said nothing just went off to be alone crying.

   That Friday Moses appeared uninvited and asked if Jack had let me know
what the deal was.  I rounded on him and said yes, blackmail!  Moses
laughed and replied that I was a slut at heart then asked in a whisper if
I'd told Jack what we'd got up to the previous Saturday.  When I kept
silent he grinned.  I knew I could deny it if he told Jack what we'd done
but I don't lie and if I did Jack would know in an instant.  So Moses took
my arm then and with a little wave to Jack headed to the bedroom.  I wasn't
going to argue with him I felt he had all the power.

   That first Friday was quite unpleasant because it was a little like a
rape; I was doing it because I had to not because I wanted to.  It was
strange because the sex the week before had been powerful (if a little
scary because I'd got carried away) whereas this was cold and passionless.
I guess he knew he could take advantage of me whenever he wanted and
reinforced this by sending an email to both of us with a clip of me talking
about sex with a stranger (it was a fictional event I made up) which
painted me as a really cheap whore and at the bottom he'd added the general
email addresses of both Jack and my offices.  The implication was clear
even if he never said it in the email.

   So he returned the next week and we had sex again I responded to him a
little that week (his cock was after all big and the sex lasted an hour)
which upset me but I kept this from Moses as best I could.  After that
night I pleaded with him saying that it couldn't be that much fun having
sex with someone who was largely passive.  He shrugged but I could tell it
wasn't as much fun as he'd hoped so he finally agreed to end this but would
want something first.  I thought it would probably be another night at his
place like the wild one which actually I thought I could do (and would
enjoy).

   A few days later however he sat us down and told us that what he wanted
was for me to go on holiday with him, willingly and as he put it
enthusiastically.  Since I was absolutely desperately to end this I agreed
even though Jack was reluctant.  To be honest I could have toughed it out
with Moses but I could tell that firstly he was likely to keep visiting for
weeks and secondly there was the danger that I might get me off a lot more
than the previous Friday which he would have taken as the green light to
keep the whole affair going for months.  He booked a short-notice holiday
away just two weeks ahead and after I confirmed I could get the time from
work we were set.  Despite this he still turned up the next Friday for sex,
which he got and this time I was quite passionate with him telling him it
was his reward for agreeing to end this.

   The holiday was of course one long sex session: We went to Greece and we
were in bed almost all the times so I barely got to go out at all.  I have
to admit that once there I decided to let myself enjoy it and we had some
really great sex.  I even had to do some late sun-worship so I didn't
return to work pale (work knew Jack was not going so would have been more
than a little suspicious!).

   I flew home unwashed with my body sticky with Moses semen; his present
to Jack, as I'd joined the mile-high club.  I also wore very little; just a
sundress and sandals.  Once home he stripped me in front of Jack showing
him my recently used body.  Jack just stared as Moses gave me a final kiss
goodbye (deep and fully reciprocated) then left me still naked in front of
my husband.

   Jack was very, very contrite fearing the worst but I kissed him also,
then told him he'd better make love to me or else!  He did and despite
being loose and a little messy it was actually great fun and we both got
off on it.  The next day Jack said how truly sorry he was, then insisted I
give him all the nasty details which I did.  I enjoyed this and left
nothing out: I played with him as I told him how, from the Monday to
Wednesday night, thanks in part to Viagra Moses had screwed me upwards of a
dozen times in all positions including on the balcony in sight of several
other guests.  Jack also got very excited about our sex on the plane (which
I have to admit was one of the best experiences of my life) and he came
over my hand for about the third time that night.

   However it had been a very disturbing reality since meeting Moses and it
had to change so I refused point blank to dress up for him like that again
and he agreed we would try to have a more normal marriage.  I saw Moses
just once after the holiday.  When he came over and gave me a flash drive
containing the videos Jack sent him (he promised me these were the only
copies he had) plus lots of shots of me naked on holiday including around a
dozen taken in the bathroom mirror as he took me from behind.  It was weird
standing talking to a guy I'd had sex with thirty times or more over a
seven day stretch as if we were just polite friends and in the end I
succumbed and took him to bed for an hour.

   I felt very guilty about that and was determined to never repeat it so
cut off all contact with him.  Jack is relieved about this because he
realises just how whorish I became with Moses.  I also avoid dressing in
any of my sexy clothes because we both know where a short dress will lead
me...
