Gary and Sophie were your normal student couple. They met in their first year at college and by the start of year two had rented a flat together. They were both outgoing and sociable and able to talk to each other on just about any subject.

Gary was tall and good-looking without being especially athletic, whilst Sophie was a bit of a cutie with blonde shoulder-length hair. Her best asset was her pert arse which was always getting plenty of admiring glances from the male students.

Their sex life was good. Gary had an above average seven-inch cock which he would use to bring Sophie to an orgasm whenever they had sex and Sophie was willing to give oral to Gary when he asked.

One afternoon after their studies had ended, Gary and Sophie were wandering around town when Sophie noticed an 'Adult Sex Shop' down a back lane.

"Do you fancy having a look in?" Sophie asked.

"Why not," Gary replied.

Inside, they looked at the sex toys, magazines, and videos available whilst being aware of the sex video playing on the TV screen in the corner of the shop. The video playing was showing an attractive blonde girl being fucked from behind by a clearly well-hung black stud.

Gary and Sophie agreed to buy one video each to watch when they got home. Sophie also bought a sex toy but kept it hidden from Gary, telling him it would be a surprise for him later.

That evening, whilst lying in bed, Sophie suggested they watch one of the videos they had bought before having sex. They watched the one Gary had bought, which was about a girl having a threesome with two fit young white guys she had met at the gym. Sophie was clearly getting aroused watching the video, constantly rubbing her pussy whilst watching the scene unfold.

When the video ended Sophie pulled Gary on top of her and begged him to fuck her. Gary noticed immediately that she was more aroused than he had ever seen her before. The sex which followed was more vigorous than before and Sophie more vocal than Gary could remember as they fucked themselves to a fabulous climax.

The following night, Gary was looking forward to a repeat performance and was interested in Sophie's choice of video. He was somewhat surprised to see that it was the interracial video that had been playing in the sex shop. If Sophie had been aroused the previous night, it was nothing to the effect this video was having on her. Her moans of pleasure as she masturbated watching the blonde girl being banged by the jet-black stud on the screen left little to the imagination.

She worked herself up to such a frenzy that she begged Gary who himself was now sporting a full erection from watching the scene unfold to "fuck me like he would". They fucked like crazy for less than a minute before they has almost simultaneous orgasms which ended with a combination of their sex juices almost soaking their bed.

They both agreed that the videos had taken their sex life to another level.

The following day Gary began to wonder if Sophie had a 'black cock fantasy'. Her choice of video and her reaction to watching it sounded very like what he had read online from a woman who had that fantasy. Gary knew that he should be concerned, but the truth was he was secretly hoping she did.

That night, Gary was sitting up late watching football, so Sophie was already in bed when he turned in for the night. As he went upstairs, he could hear more moans from the bedroom, and as he opened the door, he saw Sophie watching the interracial video again, only this time she was pushing a ten-inch black dildo deep inside her.

She seemed oblivious to Gary being in the room, and as the black guy in the video shot his load into the blonde girl, Sophie had another explosive orgasm as her juices flooded her new toy.

Gary realised that the subject of Sophie's black cock obsession needed to be addressed but Sophie denied it and said she loved Gary and that the videos and the dildo were just a way to spice up their sex life.

The following day, Gary was at the gym and as he finished his workout and went into the changing rooms, he bumped into two black guys, Jamaal and Callum, who were also regulars at the gym and whom Gary had often chatted to whilst working out.

They had also just finished their workouts and, like Gary, were going for a shower before going home. Although Gary had often seen them working out and was impressed by their well-muscled, toned bodies, he had never been in the showers with them. Gary went into the showers first and was soaping himself down when Jamaal and Callum followed him in.

Whether it was the events of the previous few days or not, Gary couldn't resist looking directly at Jamaal and Callum as they entered the showers. He had to stifle an audible gasp as he saw what was hanging between their legs. Alongside their well-muscled, jet-black toned bodies, between their tree-trunk legs were two magnificent huge black cocks.

Gary felt his own cock start to twitch, he was not gay, but he needed to finish his shower and get dressed quickly before be embarrassed himself.

Although Sophie had denied she had a black cock fantasy Gary suspected otherwise, and that evening whilst having sex he told Sophie what he had seen in the showers at the gym. He told her how big and black their cocks were and then teased her by saying that he thought they would love to fuck her hot white pussy.

This was too much for Sophie, and she had another explosive orgasm. The following morning, he woke up to find Sophie with her ten-inch black dildo deep inside her.

Gary knew that if Sophie came face-to-face with Jamaal and Callum, she would not be able to resist them. Although Gary knew that what he was planning could destroy their relationship the truth was he was as desperate as Sophie to see her getting some big black cock.

The next time he saw Jamaal and Callum at the gym, Gary invited them back to his house for a few drinks, telling them that his girlfriend was looking forward to seeing them. He said it in a way that Jamaal and Callum both understood what Gary was suggesting.

Gary had told Sophie he was going to invite Jamaal and Callum over for drinks, but not his real motives. As it was a hot day Sophie was wearing just a crop-top and a pair of hot-pants which showed off her pert arse at it's best.

When she opened the door to greet them, Jamaal and Callum couldn't take their eyes off Sophie. She was also taken aback by how hot and sexy the two black guys were.

For the next couple of hours, the drinks flowed freely, and any inhibitions that any of them had were gradually disappearing.

Gary then brought up into the conversation that Sophie and he had just bought a couple of sex videos and that Sophie had chosen an interracial video.

"Have a bit of a black cock kink have you?" asked Jamaal.

Sophie smiled nervously before admitting, "Maybe."

"Ever thought about trying one out for real?" asked Jamaal.

"I couldn't cheat on Gary," explained Sophie.

"It wouldn't be cheating if you had his permission," Jamaal replied.

Sophie looked across at Gary, waiting to see what he would say next.

"If it is what you want and I think you want it really badly, I would not stop you," Gary responded.

"My only condition is that I can watch it all," Gary added.

"OK, let's get started," said Sophie.

Jamaal and Callum both stood up and moved across to Sophie, feeling her up and slowly removing her items of clothing. First, her crop-top, which gave them access to her 34DD breasts as she was wearing no bra. Next, they removed her hot pants and finally her already damp panties, leaving her completely naked in front of them.

Jamaal tapped Sophie on the head, signaling for her to drop to her knees in front of him. As Jamaal removed his shirt to reveal his magnificent six-pack, Sophie pulled down his pants and boxer shorts in one go and was shocked by what sprang free.

"OMG. I have never seen anything that big in my life," Sophie gasped.

Gary, standing in the corner, gasped as well. He had seen Jamaal in the shower at the gym; he was flaccid, but still at least eight inches. Here he was semi-erect and must have been closer to ten inches.

Sophie knew what to do and tried to suck as much of Jamaal's cock as she could. She managed to get as much as three-quarters of it in her mouth before gagging on it and letting it out of her mouth.

Callum wanted his turn next and stripped off to reveal another well-sculped body and similar sized cock.

As Sophie began sucking Callum's cock, Jamaal had started fingering Sophie's pussy first with one finger, then with more, causing Sophie to moan as her sex was being taken by these hot studs.

Jamaal then bent Sophie over on all-fours as he prepared to push his big black cock deep into her love hole. Her first proper black cock. Her last chance to change her mind, but everyone in the room knew that was not going to happen.

In the corner of the room Gary's pants and boxer shorts were around his ankles and he was gently wanking himself off watching his girlfriend's (and he realised his own) fantasy come true.

Jamaal gradually, inch-by-inch, slid his huge cock deeper and deeper into Sophie's now soaking wet pussy. Sophie was still, between moans of both pain and pleasure, sucking as much of Callum's cock as she could. Nothing she had seen in her videos could prepare her for this, though.

Sophie had never been filled like this before. As Jamaal made his final push she let out a loud moan before she relaxed knowing he was all the way in, deep inside her womb where no cock had been before.

Whilst Jamaal rested to allow Sophie the chance to get used to the size of the weapon deep inside her, Gary went into the bedroom to get Sophie's interracial video and put it on the TV in the room where they were making out. Callum pulled his cock out of Sophie's mouth so she could see the screen.

Jamaal pulled his cock back to the entrance of Sophie's pussy before holding on to her hips as he re-entered, slowly at first, but gradually increasing the tempo as he began to fuck her like she had never been fucked before. Sophie stared at the screen ahead watching as a black stud rammed his huge cock deep inside a willing white girl. She now knew what that girl was feeling, for that was what she was feeling herself.

For what felt like an eternity but was probably only a couple of minutes Jamaal rammed his cock in and out of Sophie's pussy, each time going faster and further inside her precious feminine body until finally he let out a masculine roar as he shot his fertile seed deep inside her womb, causing Sophie to moan loudly herself as her own orgasm swept through her body.

In the corner of the room, Gary had shot his load, and his spunk was dribbling down his leg.

As Jamaal pulled out and went to the bathroom to shower, Callum asked Sophie if she was ready for a second helping.

"Give me five minutes," she replied.

Soon, Callum had carried her into the bedroom and had her on the bed in the missionary position. The events earlier had obviously gotten him well aroused because he was only banging Sophie for about thirty seconds before he added his potent seed to that Jamaal had left swimming in Sophie's womb.

After they had both showered, Jamaal and Callum left, saying they hoped there would be a repeat performance.

Four weeks later, Sophie's period was overdue. She went to the pharmacy to get a pregnancy test and when she came home and took the test, it was positive. She was pregnant with a black baby.
