The Hypothesis

The Hypothesis

My wife and I have been together nearly 5 years and I am as much in love with her as when we first meet. I had never considered watching Julie (my wife) with another man, the thought had never crossed my mind until recently. Before I explain what happened, a little bit about my wife.

Julie is a very caring and loving wife; one who would go out of her way to help others and would never consider cheating on her husband. She is 33 years old and a year younger to me. I consider her to be beautiful in general with 36 C breasts, puffy nipples, a well - rounded butt, of average build and light brown hair. I should not tell people this, as Julie would go mad lol. But, she has pubes – not like many of your nowadays models. She trims them, so it does not like look the Amazon downstairs lol

I know other men look at my wife with lustful looks, but I tend to act as if I have no idea of men staring. I love to imagine their thoughts and fantasises about her, and masturbate about being one of these strangers seeing and thinking about my wife. The thought and image of my wife with another man drives me mad with lust!

I had no idea of cuckolding and the lifestyle that goes on around it. I have obviously heard about swinging and dogging, etc. The latter has never interested me to be honest, but cuckolding did feel me with a morbid fascination when I read about a teacher fucking a student and the word cuckold husband was used in print. Like all men I had lusted after certain female teachers at school, but now my masturbation fantasises turned to imaging my wife as the said female teacher seducing the willing male student of hers!

It was these thoughts, feelings and images that lead me to become more enamoured with cuckolding and lead to my wife living out the fantasy.

As a bit of background, my wife and I both work in the scientific community. I will not tell you as what, as we like to keep our identities a secret. But, it was as researchers that we started my cuckolding and the creation of the hypothesis.

Excellent start brainbox1, I would love to read more on this.

Always a delight to see the beginning of a new Brainbox tale !!

As stated earlier, I stumbled upon cuckolding and felt as if I belonged to a sexual fantasy identity. This started to form little ideas in my head when having sex with my wife. Now Julie is not like one of these passive wife's who just lies there and takes it; in fact she is sexual adventurous and is up for most things that stimulates the mind and body. It was her who initiated the idea of light bondage and of me fucking another woman while fucking her! The latter fantasy did not work for me, as I love my wife too much to imagine cheating on her; but it did lead to us discussing fantasises and my comment on the female teacher I read about. Julie loved that idea and has had me imagine she is the teacher and I the willing student when fucking.

This willingness to be open about our sexual fantasies made me mention cuckolding to her. She of course was interested and asked me about 'this cuckolding'. She mentioned that she knew other men checked her out and that I had seen other men staring at her (there was me thinking that she was oblivious to this!). But, she did not think that I wanted them to fuck her! I explained that it just a fantasy (back tracking a bit here) and that fantasy is different from reality.

Now the cat was out of the bag, my wife encouraged me to use the idea of cuckolding in our sex life. As most people know, sex is 90% in the mind and good sex is fuelled by fantasy, so involving the idea of cuckolding led to hot, steamy sex sessions between Julie and me. It was like we were teenagers again lol

After one of these sessions, Julie inquired about me wanting to have ********. As of yet it has not happened for us and we have spoken about being parents more than once during our marriage. I again made a little joke of wanting 3 ******** - "one of each" sex, which Julie gigged at; but seriously, I told her that I wanted a boy and a girl. Julie mentioned that she was unsure why she has not got pregnant and sounded sad. We have not approached any doctors about our fertility, because we assumed that what will be will be, and things will happen in time.

During this conversation we spoke about the science behind fertility, and I mentioned a study that said men and women were most fertile in their mid to late 20's. Now my wife is not over-emotional about her lack of pregnancy and has approached it with her scientist hat on. This led to her asking if ethnicity and culture made any difference to fertility, which peaked my interest. Why? Well many of the cuckold stories I have read recently have been about black men and white women, and of course I have heard the rumours about black men having big cocks! One study I read concluded that having a big penis is better for impregnation in certain sexual positions.

This I mentioned to my wife and she wondered out aloud if a white women is more sexually receptive to a black man because of the taboo of it, and that this makes her body more receptive to impregnation. We have no evidence for this and this we discussed. Of course, for scientific rigour, I added that maybe any ethnicity, not just black men, may make a white women more sexually receptive. By this time, my cock was as hard as rock and Julie noticed this and teased with the idea that I was fantasing about her being impregnated by a black man! Julie was giving me gently strokes of my cock which made me exploded with lust; I blurted out that I was fantasing about Julie being fucked by men from different ethnicities and becoming a slut to the science of it all!

Now that done it lol I shot my cum up in the air and it landed all over my wife's hand –"my, my" she replied – "who was a little horny then"! Now I could not deny that and just replied that it was "one hot fantasy"! She giggled and said that we should use this fantasy next time we fucked. This we did to my huge enjoyment!!

Keep going brainbox, I love the slow and steady build up to the main event!

I do love your stories. It is so easy to actually believe they are real. Thank you.

There is NOTHING in words that stimulates like a Brainbox story. Please continue babe.
Loving Wife, Mother, and Bryan's Slut

About a week later, and after another sex session that included her being fucked by men of different ethnicities, we spoke about the fantasy and whether any cuckold couples have done anything like this. I wondered out aloud if there were cuckold sites where people wrote in about their experiences, which piqued my wife's interest. It was her who encouraged me to find out and if so, make a post asking about it!

Well this I did and apart from inquires about whether I was a cuckold and people
asking for my wife's pictures, no-one wrote that they had ever down anything like what I inquired about.

I took this back to my wife and we discussed how such a study would be set-up. Again, this fuelled a great sex session and after we stated opinions about whether such a study would be double-blind or single-blind, a case study or randomised controlled study, the test protocol, and joking around whether we need to get ethical approval before doing it lol

Our bedroom was now awash with sexual innuendo, teases about my wife meeting a big cocked stud and running off with them or of being impregnated, and me becoming a cuckold. The latter was now turning into an unwritten rule.

I asked Julie how we could create the perfect scenario for her to have sex with other men, and test out a hypothesis seen in the cuckold stories – 'that black men are better at sex than men from other ethnicities' – Julie said that such a hypothesis was "stupid" as it depends upon the man and such a sweeping generalisation could not be scientifically tested accurately. I countered that it would not be a perfect study, but it could raise interesting questions and point to a trend that would need further testing –like all scientific studies if the truth be told.

Julie was not convinced by this and argued that if the men had sex with different women than the results were be null and void because of the confounding variable. I stated that if such a confounding variable stayed constant than this would eradicate said bias. Julie uhhhed and ahhed about this view and said 'good luck on finding a woman to test it out'! I snuggled into her and whispered in her ear that we need a good researcher to test it out and she was one of those! Julie lifted herself up at that point and looking at me asked if I was "serious"!! I smiled and said "yes, why not test it out"? She looked at me with a puzzled frown and laid back. I thought for a moment that I had fucked-up but Julie looked over at me and said that she "loved me" and had no interest in "cheating on me". I smiled back and gave her a kiss – I then said that it was "not cheating if I knew and gave my blessing". My wife gave me a look and turned over saying that she would "sleep on it". Snuggling up to her and closing my eyes I started my dream of Julie fucking other men and making me a cuckold.

Like always, you keep me on edge all day thinking about your writing. Just marvelous. I can't thank you enough. I know it takes effort. Please give us more when you can spare it.

xox,

Donna
Loving Wife, Mother, and Bryan's Slut

Donna, I hope your being "kept on edge" also keeps your hot little pussy nice and wet and receptive, and you're getting the opportunity to scratch your itch!

The next few days nothing was said about our late night conversation and married life and work carried on. Till my wife came home one day and mentioned that a new research study was being planned at work and was discussed with her and her colleagues. This gave me an opportunity to inquiry if she had thought anymore about our study? She smiled and called me "incorrigible". I asked her again. This time Julie replied with a "yes" and that if I wanted to play this out then we need to discuss it further.

That night when we had some time away from domestic stuff we had our discussion. It consisted of: who would be the men, how could we pick good choices, how old would they be, would it be bareback or with contraception, where would the fucking take place.

Julie and I discussed advertising for participants, that we meet them first before continuing (no fucking on first date!), that without contraception STD's and other disease were possible; but that bareback was more likely to encourage sexual lust and make her and her lover more receptive to impregnation, so that any participant be asked for a recent D&D certificate and without one they would be eliminated.

This then lead to us discussing the age of said participants. As scientists that sperm was fully mature by a male's age of 16 years old and that studies such that around the male's age of 35, sperm becomes weaker and the thus the male becomes less fertile.
All of which meant that the age range of the participants would be 16 to 34yo.

Now earlier I mentioned the story of the female teacher and her student and how that fuelled our sex sessions. I raised this in our study planning and Julie sighed and asked if I was saying that she had to be fucked by a teenage boy! I nodded and said that we should go for teenage boys aged between 16 to 18 years old; one because they were horny at that age would fuck anything female (Julie hit my arm at this point and told me that she "wasn't anything female"!), and as such would not have many hang-ups about cuckolding a husband; they would be more than likely be unattached (so no wife or girlfriend to cheat on); Also, Julie would probable not fall in love and leave me for a teenage boy.

As I stated all this Julie was nodding her head and agreeing. She asked where she would be fucked and mentioned a hotel room. I countered with the expense of doing this and of bumping into people who would talk about my wife being with different teenage men and the risk of it getting heard by people we know. I mentioned our bed and how cuckold's who have posted on the cuckold site loved their wife being fucked in the marital bed. Julie shook her head and smiled and said that she was worried that the teenage boys would know where we lived and may blackmail us or not leave us alone (hoping for more fuck sessions!).

I replied that blackmail could be case even if we did it in a hotel and that if we meet the teenagers first, as planned, then we could minimise the said risk of meeting a "nutter"! This made my wife laugh and she agreed how exciting this study could become.

We then agreed the participant's criteria: Males – African or Caribbean black, Chinese, South Asian (i.e. India, Pakistan) and white. Thus, my wife would fuck 4 teenage boys aged between 16 to 18 years old of said ethnicities.

The next step was agreed to be the advertisement. I wrote it and Julie edited some of it:

"seeking men aged between 16 and 18 years old to fuck my wife, who need to be one of the following: African or Caribbean black, Chinese, South Asian (i.e. India, Pakistan) or white. She is very beautiful, 5' 7" tall, brunette, 36c breasts with perky nipples, a flat stomach (my wife's addition!) and a tight firm ass (my addition lol). She's a size queen so do not respond unless you have a long thick cock (my addition much to my wife's annoyance lol). You will be fucking her bareback and she is not on any birth control. Pregnancy is a risk but not your problem! We meet first and then decide at the second meet whether to continue.
I then posted on a number of cuckold and interracial websites.

Great story, I'm loving every minute of it. Good idea to deliberately choose much younger guys, knowing full well that they could fuck Julie without mercy, leaving her exhausted, but still wanting more hard cock. I loved the bareback and no birth control involved, how fuckin" HOT is that!

HOT!! HOT!! HOT!!

This is becoming one of Brainbox's epics in the vein of Humiliated by a Boy, still my favorite all-time story.

I already have a drenched thong sitting here in my office.

Thank you Brainbox!

mail it to me. xx

The replies were slow and many asked for a picture first which we replied with a straight no! That way time wasters would be whittled down. After 2 weeks, the advert had resulted in 10 replies – most of which we decided for various reasons were not suitable (e.g. saying they were going to make me a sissy; not including a cock picture, etc.).

We contacted 4 of the replies (3 said they were black, one said he was white). Their private messages I read with Julie in bed and led to wild fucking as we got more into the cuckolding fantasy. Most of the messages detailed how they would fuck Julie. We agreed to meet 2 of the black guys and the white guy. I was permanently horny imaging Julie being fucked by a teenager with a big cock! Now we had agreed to meet some of the participants it was getting nearer to becoming a reality.

Over the next 2 weekends we meet the participants in public places and discussed what we were planning. One of the black teenagers was far too immature and just spoke about how big his cock was and how he would stretch my wife out and have her screaming – I could see that Julie was unimpressed with this individual, so we ended the meet early and decided not to proceed with them.

That left 2, both of whom we decided would be OK. Darryl was an 18 year old black male from an African background. He was taller than me by 5 to 6 inches and well built (said he worked out a lot!). We had seen his cock picture and flaccid it looked larger than mine and he had said that it was 8 inches when hard. Surprisingly, he was quite shy but talkative. He did not brag and I think my wife got a little crush on him because of this.

Ryan was a 17 year old white British male. He was about my height and slim. We had seen his cock picture and Julie was shocked at how big it looked on his slim body lol Flaccid it looked massive and he included a picture of it hard and it looked bigger than a donkey's! He said it was 10 inches hard and my wife and I doubted that because it did look massive! In fact, its girth was not far off a coke cans at first glance! Julie joked that he would ruin her pussy for me afterwards! Ryan was lot more cocky than Daryl, but in a boyish way rather than a jerk's way! It looked as if Julie was more enamoured with Ryan than Darryl because of his 'bad boy' vibe.

Darryl and Ryan both agreed to our requests, but neither had D&D certificates, but agreed to get them. We agreed to meet again a week later and if they had the certificates they would get to fuck Julie. I swear us men all had hard-ons at this thought!

Mmm.......You're right on the brink of something new and very exciting here, brainbox!

I have so many emotions going on right now. Totally horny, wet, almost sweating with desire.

Thank you again Brainbox.
Loving Wife, Mother, and Bryan's Slut

That's really strange Donna, I'm feeling the same, but I suspect for a different reason! xx

A week later we had received a further 3 replies; 2 were from black guys and one was from a Pakistani teenage boy of 16 years old! Adil said he had never fucked a woman before and my wife wondered if it would be right to be fucked by him because of this, and because in our study we had not factored in Julie being fucked by a virgin!
When we discussed Adil and his suitability; Julie got off on the thought of teaching a virgin and the thrill of it. Adil had the smallest cock of all the replies and when pushed said he was 7 inches hard and circumcised (Darryl and Ryan both had foreskins). His cock size was not in keeping with the advert request, but Julie was adamant about meeting him, so we did.

By the time of meeting Adil we had meet Darryl and Ryan again and seen their D&D certificates. I had lost a bet with my wife that they would flake out and not bother getting tested – it cost me a clothes shopping spree by my wife lol

Adil described how he is a British born male from Pakistani heritage, whose parents were pushing him into marrying a girl he had never meet. He explained how he wanted to fuck a few girls before marriage, but found it hard to meet any girls who would fuck him, hence his reply to our advert! To me he sounded desperate, to my wife he sounded adorable! So he became participant 3 in our study.

The times and dates for Darryl, Ryan and Adil to fuck Julie were agreed and mobile numbers taken. We stated what we wanted and the rules of fucking were agreed. The fucking would be on a weekend and on an individual basis. The boys had asked previously if I would be involved or watching and I said I would not be; but, I would be downstairs listening in to make sure everything was OK. I think Adil was particularly happy with that, but Ryan seemed a bit disappointed!

Julie and I spoke after about her fucking the boys. I had a brain wave and asked Julie if apart from testing the study hypothesis, that we also add in some discussion points. Julie asked me what I meant by that and I explained that she also rates them on their sexual prowess, cock and ball size, how much they cum, how good they kiss, their oral sex skills and imagination. Julie jokingly replied that she would be far too busy to monitor all that! Lol I explained to her that we could do the rating afterwards (and not during!). Julie replied that she was worried that Adil would be at a disadvantage –to which I replied that she could give him a points start over Darryl and Ryan. However, Julie stated that this was a scientific study and doing that would be researcher bias! I had my doubts though, but kept my mouth shut.

We now had 3 out of 4 participants and needed the Chinese teenage boy. He would come from an unexpected source!

Wow Brainbox this is a very interesting and unique story. As always you make me hard and wanting more.

Magnificent. Just thinking of this scenario is so hot.
Loving Wife, Mother, and Bryan's Slut

I bet you would love to break in a teenage virgin, Donna!

Darryl was the first up. Prior to his arriving my wife had asked –"how did you feel about it"? With my heartbeat rising and my face flush I replied "if it's what you want then I am all for it". Julie felt this was an unacceptable answer and said –"No, do you WANT me to go through with this"? My reply was in 0.5 seconds flat lol A straight and univocal - "Yes!

The experience was like a strange dream! Darryl had arrived and my wife had led him by the hand upstairs, with me standing at the bottom of the stairs watching them heading for the fucking! Darryl had looked back with a big smile on his face (lucky bastard!) and placed his hand on my wife's tight firm ass. I was mesmerized by the sight in front of me.

My 33 years old white wife was going to be fucked by a black teenage boy nearly half her age in our marital bed and bareback at that! Man the thought and imagine still sends shivers down my spine.

No doubt my wife had left the bedroom door open because downstairs I could hear her moans and groans and the grunts of Darryl. I could hear Darryl say – "suck it good babe" and "take it"! I heard the bed shake and bang against the wall as Darryl really went at it lol Thank god the neighbours nearest to our bedroom were on holiday because god only knows what they would have thought!

Julie's shouts of "oh god, oh God" and "Yes, yes, YES" were no doubt put-on for my benefit and to encourage Darryl! I heard Julie shout "you are sooo DEEP"! To prove that Darryl had a bigger cock then me!

On 2 occasions I heard Darryl say that he was cumming and the moan of satisfaction coming from my wife. The image I had was one of Darryl's muscular body tensing and Julie wrapping her arms around him and pulling him deeper into her; his fertile, potent black sperm shooting inside my wife's pussy and seeking out her eggs to impregnate her! Man I masturbated like a madman with this imagine in my head!

All this went on for about 2 hours! After Darryl had left, Julie gave me a hug and said she loved me. I told her that I loved her too and she asked if I was OK. I took her hand and placed it on my hard cock! That was physical proof that I was OK with it lol She smiled and looking in my eyes replied that "I was a good LITTLE boy" before patting my bulge and laughing.

Julie had a shower and put on her night dress and dressing gown and met me downstairs. Here we started the rating process and used the spreadsheet we had recently developed for this occurrence.

Darryl's ratings: (1) Sexual prowess = 7 / 10

(2) Cock Size = 7 /10 (Julie had giggled when she said a 10 would be a cock 11 inches +)

(3) Ball Size -= 6 / 10 (Julie said they were only average in size –I am not sure what she was wanting; maybe football sized balls???)

(4) Cum Amount = 6 / 10 (Julie said Darryl cum no more than I did)

(5) Kissing ability = 7 /10

(6) Oral Skills = 4 /10 (Julie explained that Darryl was not keen on going down on her and instead preferred to suck her tits, kiss and fuck her)

(7) Imagination = 6 / 10 (Julie said that Darryl was just a straight 'fuck and leave them' type of guy)

Overall Rating = 37 / 70 (52%).

Next up was Ryan – could the white teenager do better???

Now we're getting into the nitty-gritty of this tale, and it's fucking good - you don't disappoint.

Gosh this pushes my buttons. Or, at least makes me rub my button. Let's get that big white cock in Julie's pussy!
Loving Wife, Mother, and Bryan's Slut

I've told you before Donna, that's my job! Call me when you're ready next time! xx

Ryan was slightly different. He had asked that my wife shave her pubes as he did not want to swallowing hair! This made my wife laugh and made us realise that Darryl may have had the same thought. Although, my wife replied that she would have shaved her pubes if Darryl had asked and this was not why he did not "suck her pussy"!

With Julie's pussy shaved we awaited Ryan. When he arrived to fuck Julie he stated that he wanted to stay the night! Julie looked at me and smiled and I just sighed and nodded my head. Julie clapped her hands and told me to ***** in the spare room while a teenage boy fucked her "brains out"!" Wow! She was really getting into this. Ryan smiled and crocked his head to the left. He then caught Julie and me out by turning towards her and kissing her on the lips. Julie was a bit surprised and let him kiss her and feel her up for a bit. I could hear the wet sounds of their mouths and tongues entwining. Ryan gently put his arms around her shoulders and pulled her close, like she was his property now. Julie offered no resistance and put her arm around his waist as they made out in the hallway. Julie started to squeeze and caress Ryan's cock through his trousers, and they looked like they were going to burst at any minute with the size of his cock! They broke their embrace and Ryan told my wife to say good night to me, which she did with a giggle. As they went up the stairs hand in hand, Julie turned back at me and whispered "MASSIVE" to me. No doubt she was talking about the size of his cock! As she said this Ryan reached under her short skirt and squeezed her ass. She then turned back to him and squealed and giggled.

They were now out of sight, but not out of sound range!

The night seemed long; the rhythmic sounds were ********. There was the repetitive knocking of the bed head on the wall. The sound of Julie's feint gasps and groans as Ryan triggered the inevitable orgasms, that which caused her body to shudder beneath him.

Listening to the noises Julie makes when she is being fucked is amazing. I could hear Ryan calling Julie a "fucking slut" when he is fucking her. Julie just screamed out that "yes, yes, I am a slut"! What a turn on. She would never let me call her that, when I tried she said it's disrespectful, I should not call her that.

At the beginning of their fucking I sat outside the bedroom and listening to Julie moan, unfortunately they both don't want me actually present. When I had tried to peek in and enter the bedroom Ryan had told me to "fuck off" and Julie had turned her head and also shouted "fuck off"! Before giggling and telling Ryan to fuck her with his "BIG COCK"!

I did not think I would have liked Ryan staying the night, but I did. I imagined them
cuddling up together in our marriage bed, little; butterfly kisses between them, and my wife feeling that massive boy cock nudging against her body.

I feel a***** and awoke with the groans and moans of my wife once more reaching a
crescendo and imagined Ryan's fertile and potent young sperm invading my wife's pussy and hunting out her eggs to impregnate her! Man, I masturbated over that imagine more than once lol I could only imagine how Ryan's BIG COCK was stretching Julie's sweet, tight pussy Wider than it has ever been.

Strangely in the morning before he left, Ryan apologised for telling me to "fuck off"; I replied that it was "cool" and "no harm done". He just laughed and said "you have not seen your wife's pussy yet"! I would prefer it if he was much more mean and horrible to me, but he is really polite and nice to me, when he was not fucking my wife that is.

As before, my wife asked me afterwards if her cuckolding me made me jealous and did I want to stop it, She held my hand and looked me in the eyes and said she would stop the study if I wanted. I shook my head and said "no", carry on; I am loving this". She smiled and gave me a slap on the arm and called me a "pervert". I believe that I had now made her understand that it is a blessing if one has an adulterous wife, who still loves her husband and fucks teenage boys just for lust and fun.

Julie rated Ryan as below:

Ryan's ratings: (1) Sexual prowess = 8 / 10

(2) Cock Size = 9 /10 (big, but not 11 inches +)

(3) Ball Size -= 8 / 10 (Julie said Ryan had big balls, the size of eggs!)

(4) Cum Amount = 8 / 10 (Julie said Ryan was like a fire hydrant lol )

(5) Kissing ability = 6 /10 (Julie said that Ryan was a wet kisser and better at fucking)

(6) Oral Skills = 5 /10 (Again, Julie was disappointed. She explained that Ryan did suck and caress her pussy with his tongue and mouth, but only for a few minutes at a time – she said she was just getting off on it when he stopped)

(7) Imagination = 6 / 10 (Julie said that Ryan, for all his bravado, was another straight fuck)

Overall Rating = 50 / 70 (71%).

Wow. I could use some Ryan cock about now.

Thank you Brainbox.
Loving Wife, Mother, and Bryan's Slut

Donna, I bet you could train Ryan to improve in all his weak areas. Mind you, it would probably take you weeks of intense lessons for him to shape up, could you put up with that?
