Author's Note: Fluid bonding is a term I've seen frequently in the polyamory community but never outside it. I'd like to take a moment to define it here just in case. Here's the definition: "Fluid bonding refers to the decision to stop using barrier protection during sex and exchange bodily fluids with your partner. During safer sex, some barrier methods, such as a condom or dental dam, reduce the chance that you and your partner will share fluids." You can go read the full article if you like.

Chapter 26: Donations

As soon as Joan and the Kaiba brothers had seated themselves in the limo, Roland snapped on a pair of latex gloves. "Mrs. Kaiba, may I?"

"Sure." Joan held out her finger and received a lancet prick. Roland prepared the HIV test strip and opened a fresh kit for Seto. Both of them continued chatting as Roland took Seto's sample and unwrapped a third kit for Mokuba.

"Is this really necessary?" Mokuba asked when Roland beaconed for his finger.

"You never know," Seto replied, "and the sooner you find out, the sooner we can secure the gene therapy to stop it."

Mokuba held out his finger and let Roland prick him.

"I thought the gene therapy was still in the experimental phases," Joan said.

Seto threw back his head. "Ha! Dozens of rich bastards like us have already been cured. Those of us with more active sex lives have been funneling private donations into the research just in case. It's a well-kept secret because nobody wants the public to know about their disease. The researchers can't publish their findings until some nobody consents to release his records to the public."

Joan's eyes widened. "So if you discovered you had it . . ."

"I'd be next in line for the cure," Seto finished.

"And if I happened to get it . . ."

"I'd see to it that you get bumped to the front of the line as well."

"OK, what if Michael or Marc got it?"

"Since we've already established that you're not going to stop fucking them, fine."

Joan squealed, threw her arms around Seto, and kissed him. "We've got to tell Michael about this."

"Why?" Seto's eyes roamed hers.

"Because if he's all right with this, I can show you how I fuck him. I have an IUD by the way."

Seto nodded but cursed silently. He should have known a smart whore like her would have an IUD.

Joan dialed Michael's number and put him on speakerphone. She spilled everything to him while Seto squeezed her hand and Mokuba rested his head on her shoulder. She even mentioned the part about the Kaibas wanting an heir and moving in together.

Michael paused a long time before responding. "Joan, I'm glad you told me, but I need to think about this. Can you hold off on the fluid bonding a little longer?"

"All right," Joan conceded, "but can they at least cum in my mouth?"

"Yeah, sure."

"We'll talk more on Monday."

"See you then. Love you."

"Love you," Joan echoed.

Seto looked out the window at the setting sun. Now that everything was out in the open, he felt so exposed, so vulnerable. She loved him, she'd even told her husband, but was love enough? A heaviness he couldn't explain settled over his heart. Was this a step forwards or a step backwards?

"Negative," Roland declared as he read the test strips. The limo came to a stop in front of the Hyatt.

As soon as they stepped out of the limo, Seto took Joan's hand again and held it all the way up to the suite. Eyes followed them and cameras flashed, but the bodyguards deterred approaches.

Upon entering the suite, they dismissed Tamara for the evening and released Mokuba's bodyguard to roam the hotel. A bottle of champagne in a bucket of ice rested upon the dining table. Three crystal flutes with twisted stems stood in a row.

"Roland, what's this?" Seto asked.

Roland uncorked the bottle and began pouring. "I had it delivered to the room. I thought you might like to toast to . . . whatever this is."

"Thanks Roland," Mokuba said before Seto could find a way to ruin the moment.

"Thanks," Joan echoed.

They each took a glass and held it aloft.

"To our shared future," Mokuba proclaimed.

They clinked their glasses together and took a long sip. Butterflies filled Mokuba's stomach as he remembered what he was getting himself into and he drained the glass. Roland filled it again while Joan and Seto savored theirs.

Joan noticed Mokuba's nervous expression and put a reassuring hand on his shoulder. "Relax. It's just live porn. You have watched porn before, haven't you?"

"Well, yeah," Mokuba replied, "but . . . you're sure about this?"

"One hundred percent," Joan assured him.

"You can even join in," Seto smirked.

"But you don't have to." Joan took hold of a chair and dragged it into the bedroom. Mokuba followed. She positioned the chair at the foot of the bed and guided Mokuba into it. She then grabbed a box of tissues from the adjoining bathroom and tossed it to him. "Just in case," she said with a wink.

Seto stood leaning against the door frame. "Ooooh, smart whore."

Joan walked up to Seto and took both of his hands in hers. "Honey, I love it when you talk dirty, but consider our company."

"If I can't talk dirty," Seto ran fingers along her neck and kissed her, "I'll simply have to do all sorts of dirty things to you, Mrs. Kaiba." He stepped fully into the bedroom and shut the door behind himself.

A shiver of excitement coursed down Joan's spine as he toyed with her dress and traced the outlines of her panties. She slid her hands under Seto's trench coat and peeled it off, letting it fall to the floor. She then hooked her fingers around the belt at Seto's waist and pulled him to the bed. She tried to take off his shirt, but the belts on his arms hindered her progress. "Why do you wear all this weird crap?" she asked as she tugged one loose.

"Why do you wear this vile contraption?" Seto deftly unsnapped her bra with one hand, through her dress.

"I don't always," Joan countered.

"Neither do I," Seto smirked, "but you never know when they might come in handy."

Joan giggled. "You'll have to show me what you mean by that another time." She finished unstrapping his arm belts and got his shirt off, then stripped off her own dress and bra. Seto pressed his lips to hers and ran his hands over her supple body. Joan's fingers wandered through the valleys of the hard muscles he'd started building back up since he met her.

Seto drew her panties down and she stepped out of them, moving backwards onto the bed afterwards. She watched Seto unstrap the belts around his shins as she played with herself. She snuck a glimpse at Mokuba and caught him unbuckling his own belt. Her lips spread in an uncontrollable smile as she looked back at Seto.

Seto pulled down his pants and his erection jutted from his body. He picked up a condom from the side table, unwrapped it, and examined it for defects before rolling it over his shaft.

"Bury that inside me," Joan demanded. She grabbed a pillow and rolled onto her knees, lifting her shapely rear, inviting him to enter. Her cheek pressed into the pillow as she gazed at Mokuba. Just as she'd hoped, he was stroking a cock that rivaled Seto's.

Joan moaned as Seto's first powerful thrust drove into her. She kept her eyes on Mokuba, clenching the pillow for support as Seto's balls slapped against her clitoris. The stronger Seto's rhythm grew, the more her flesh burned for Mokuba. "Hold my hand," she pleaded, holding one out to him.

Mokuba stood and walked to her, still rock-hard as his gaze passed from Joan to Seto. He took her outstretched hand and continued stroking himself with his free one. Intense pleasure shot through Joan's arm as Mokuba made contact, and her moans rose to screams.

Seto felt the walls of her vagina convulse around his cock and the sensation sent him over the edge. With one last, hard thrust, his white lightning surged into the condom.

Joan felt hot semen splash her face immediately followed by an, "Oh shit, sorry!" from Mokuba.

Joan collapsed and rolled onto her back, giggling hysterically.

"No really, I didn't mean to do that. Did I just ruin everything?"

"Nope!" Seto pulled off his condom and proudly dangled his considerably large load.

"I think . . ." Joan breathed as she recovered.

"You came again," Seto confirmed.

"And I got cum up my nose," Joan added. She jumped up to grab some tissues.

"I'm so sorry!" Mokuba gushed.

Joan gave her nose a long, loud blow. "It happens." She blew again. "I kinda liked it. Sure you could have had better aim, but that was fun."

Seto watched Joan wipe his brother's semen off her face. Strangely, it felt like a tiny victory to see her like that, smiling over a few gobs of goo. He knew this smile was real, not contrived to please him or Mokuba. Not wanting to smell the remnants of Mokuba's jizz, Seto fought the urge to kiss her.

Closing Note: In practice, I find that many people don't take unprotected oral sex as seriously or don't consider it part of fluid bonding at all because of the much lower transmission rates. Condoms also taste terrible. Flavored condoms are OK but more expensive. It all boils down to what people are comfortable with, but fluid bonding is a useful term when one wants to hold a conversation about boundaries.
