How did her family not notice what she was doing on her 18th birthday?

As soon as I ask this question, Bobby and Jack started sniggering and Gloria tried to stifle a laugh.

"Ok, it's a good question," she said with a big smirk on her face.

"Oh fuck I'm close," interrupted Jack. "The poor man's innocence is driving me over the edge!"

"Mmm, yes, I can feel it! Are you going to cum up my sexy, dirty arse again?"

"Oh fuck, oh fuck," said Bobby, who was evidently also close to his climax.

"No, I'm gonna spaff my jizz all over your tits," announced Jack, and pulled out of Gloria's arsehole. Her hole gaped for a few seconds, slowly closing up, partly thanks to the motion of Bobby continuing to thrust into her eager pussy. Jack stood on the bed and manoeuvred himself round to Gloria's front, putting his hard cock in front of her mouth. "Taste your shitty arse, bitch," he instructed.

Without hesitation, Gloria took his cock in her mouth and started sucking. I could see from the movement of her jaw muscles, and from Jack's reaction, that her tongue was busy on Jack's tip.

"Oh fuck, FUCK, yes!" Jack shouted, pulling his cock out of Gloria's mouth and wanking in front of her. With just two or three more strokes he was ejaculating, his spunk spurting over her tits, her face, and some of it going over her shoulder and splatting on our bedroom carpet with a wet thud. The amount of cum he produced was pretty impressive.

Now that the obstruction of his cock was out of the way, Gloria could let rip with another enormous fart. A dribble of the lube from Jack's cock came out and started running down her thigh. The fart seemed to get Bobby even more excited and he started moaning loudly, increasing his pace.

"Fuck, yes, I'm gonna cum inside your pussy. I'm gonna breed your slutty cunt, I'm gonna paint your insides white!"

"Yes, fuck, give it to me big boy, fill me up!" shouted Gloria in response, "show my husband how to really breed a woman!"

"AAAAAAAHHH," shouted Bobby, gripping Gloria's buttocks even tighter. Her eyes rolled back in her head and she screamed in ecstasy as he erupted deep inside her. She continued to ride his cock, milking him for every drop.

"Uh, so big, so much cum," she said deliriously as they slowly came down from their climax. "Mmmm, so good. What was the question again?"

"Your husband wanted to know how your family didn't know what you were doing on your 18th birthday," replied Jack with a grin. Gloria and Bobby giggled again at the question. "Shall I answer it for you?"

"Mmm, tell him, big boy," said Gloria in a voice that seemed half sultry and half sleepy.

"With pleasure," grinned Jack, looking straight at me. "The answer is, they knew all about it. In fact, they arranged it."

"They.... what?!" I asked incredulously.

"What do you know about her father's business?" asked Bobby, smiling joyfully at me.

"He's an international businessman. He leads a global company with offices and outlets all over the world. He's very successful," I said.

Bobby chuckled. "That he is. But what do you know about what sort of business he runs? What does he sell?"

"I... I don't know," I admitted. Jack got off the bed and walked towards me, his dick occasionally dripping another globule of cum onto our bedroom carpet.

"He sells sex, Brad," he stated as he came close to me, bending down so he could say it right in my face. "He runs the world's biggest global network of whores, hookers, escorts, you name it. From streetwalkers to brothels to high class agencies, he has branches of his sordid empire everywhere, in every major city, every military base, every aircraft carrier, you name it. And then, only slightly more civilised, is his massive network of pornography studios and platforms. And then, maybe slightly less sordid, are the huge number of sex shops and his huge sex toy empire. From dildos to full size sex dolls, all the accessories you can think of, he has a part of his empire manufacturing them and selling them. Costumes, adult nappies, whips, ropes, handcuffs. Oh and let's not forget his pharmaceutical business. The tablets that make us fart so often and so hugely are produced by them, and they do a good line in erectile enhancements too."

My jaw dropped. I looked over at Gloria, who was now sitting up, Bobby's cum leaking visibly from her pussy. Bobby was also sitting on the edge of the bed, putting his underpants back on.

"Your dad? Peter?" I ask, incredulously, recalling the very pleasant, friendly businessman, my father-in-law. "No..... he seems so respectable, so decent..."

"He is respectable and decent," Gloria said firmly. "Don't you dare judge my dad or my family! He's fair, he's shrewd, and he doesn't make anyone do anything they don't want to do. His empire is one of the biggest because people want to work for it. We pay fairly, unlike many of our competitors. We don't engage in any sort of **** labour or trafficking. It's good honest work, and..." she paused, rubbing her pussy with her fingers, scooping some of Bobby's cum up and putting it in her mouth, staring straight at me as she did so, "...it's fucking good fun," she finished with a smirk.

"The.... whole family?" I asked, still trying to take it all in.

"Yes. My mum was such an amazing prostitute that he married her. She still works, can't get enough of it. She taught me so much," Gloria replied. "Michael works for the business too, more in logistics and back end stuff but occasionally he wets his whistle with some real action," she added, describing her older brother.

"And Laura?" I asked, referring to Gloria's younger sister.

"Yes, honey, just like me she was in the business as soon as she turned 18 years old. She couldn't wait to get stuck in. Dad's very strict about age limits. As soon as some clients knew he and mum had daughters, they were willing to pay to have us when we were younger, but he protected us from all that. He made them - and us - wait until we were 18. Anyone who tried to push their luck too far found he'd no longer do business with them."

"Wow, there are some real perverts around," I said.

"Don't you doubt it. But a lot of them will pay good money. And some of us still dress up young for those who like it. I feel so sexy in my slutty schoolgirl outfit, I'll have to show it to you sometime. When Becky and I are both dressed as schoolgirls and Mum as a teacher, some of our clients can't get enough of that."

I sat in silence for a moment, my mind blown. Bobby and Jack put their underwear back on and stood to leave.

"We'll leave you two to discuss this together," said Jack with a wink.

"You've only scratched the surface, buddy, you've got so much more to find out," said Bobby with a smirk. "Hope you enjoyed the show, I know I did."

"Yeah, thanks," said Jack. "No hard feelings, ok? We're just here doing business. And it was fucking hot humiliating you, knowing you had no clue what was coming."

"Hope to see you around," said Bobby, suddenly sounding kind, the raw aggression and domination now gone from his voice. He registered my surprise. "Hey, I'm not a monster, I just like to play dominant in the bedroom," he explained. "Hopefully you'll stick around and get on board with this. Maybe one day I'll pay to fuck that sweet arse of yours."

"M-mine??" I said, wide-eyed.

"You heard me," he chuckled. "Have fun with your wife now. We certainly did."

"I'll see them out," Gloria said to me, turning to follow them out of the room.

"Wait," I called, "what about these?" I indicated the handcuffs; I was still fastened to the chair.

"I'll let you go when I'm back," she replied. Then she turned to look at me. "....maybe" she added with a wink, and was gone.

I heard the three of them talking in low voices, laughing occasionally, as the two men got dressed in our spare room and then the three of them went downstairs. After a couple of minutes I heard the front door open, the conversation faded a little, and the door closed after some "goodbyes" were called. Then I heard Gloria's footsteps coming back up the stairs.
