————————————————

As Christine was busy in the ladies' room, Alan and Katherine were still a short distance away in the men's room.

When Katherine's blowjob ended, Alan felt so light headed that he had to sit down on the toilet. He put his head in his hands and tried to recover. "Oh God. That was intense. I hate to admit it, but I really needed that."

Katherine giggled. "Hee-hee! See? Susan and I know you better than you know yourself." LIke Alan, she was careful to say "Susan" and not "Mom" on the off chance that someone had quietly entered the bathroom while she was busy sucking him. "Aren't you glad?"

"No," he said. "This is craziness. I'll admit that I was dying for release. But if I had a lick of sense I would have just come here and jerked off."

Katherine gasped in mock horror. "Masturbation? If Susan heard you say that, she'd wash your mouth out with soap. Or, more likely, she'd get so excited picturing that that she'd make you wash her mouth out with your sperm. But either way, mouths would get washed." She giggled.

She sat down on the floor and leaned back on the stall door, because she needed to rest for a minute. She wasn't wearing anything but her blue miniskirt and high heels, but her long dark brown hair flared out and covered all of her back, so she wasn't too concerned about getting dirty. She spread her legs some, showing him that she wasn't wearing any panties. She saw her new position would allow her to comfortably play with herself, so she started frigging her pussy. She asked him, "So. How's your date going?"

He answered, "Fine. But what do you think you're doing?"

"Duh! All these constant orgasms seem to be affecting your brain. What does it look like? In any case, what were you two talking about? You two were getting pretty hot and heavy, from the little I could see. What happened to the non-romantic dating idea?"

He replied defensively, "I don't appreciate you spying on me and my date. And I'll have you know we're still very much platonic, thank you very much. It's just that she needs practice with flirting, so that's what we're practicing."

Katherine snorted with derision.

Alan ignored that, and continued, "And I gotta say that I've had so many incredible sexual experiences lately that I'm not used to so much teasing and so little action. She and I have been teasing each other for the last hour or more. I've been very clear with her tonight that things are just platonic, but in spite of that the sexual tension has been growing. You came along just in time."

She smirked. She was very happy with the outcome of her intervention so far.

He saw her look, and said, "Don't get so smug. A lot of lucky things have fallen together, so I'm not that mad at you. For instance, I don't know how no one's come into this room for the last five minutes or whatever it's been."

She snorted. "Luck? Not hardly. Didn't you see the 'DO NOT DISTURB' sign I put up outside the door?"

"Huh. Clever. But how long will it take before some employee notices that, especially if some customer who really has to pee complains? We need to get out of here, and quick. But before we do, I want to make it completely clear: what you did here is totally insane. There's no way you can do this again. Our luck is only gonna last so long. I want you to promise me right now you won't pull any stunt like this again. Especially on any date with Christine. She's dangerous. You know that, right? If she were to find out what you were doing a few minutes ago, well, I don't think she'd go public with it, but she'd find some private way to put a stop to our relationship. She's not the kind to turn a blind eye to something she finds offensive. Is that what you want? To put an end to all our fun?"

"No, of course not."

"Well then, promise me. Promise not to interfere." He stared intently at her face, doing his best not to look at her fingers working on her clit.

After she gave that serious thought, she replied, "Okay, but only on one condition. I promise not to do it again, so long as I get to make the most out of this one time. I want you to fill me down below." With a big grin, she nodded down towards her pussy.

"What, you seriously expect me to get hard again? No way. That's a ridiculously dangerous idea. How long do you think that 'do not disturb' sign will work? We're gonna get in serious trouble when they find the sign and figure out that someone inside must have put it there. And besides, even though you're looking pretty tempting diddling yourself like that, it's not enough. Frankly, I have no idea how I managed to get aroused even the first time, considering everything else I've been through today. By all rights I should be completely collapsed and dead asleep by now. Emphasis on 'dead.'"

"I know how to do it," Katherine said in a husky voice. "Just pretend I'm Christine. You two practicing all that flirting. That's what gets you going. What if she needs more practice than that? What if she wants to come into this room and practice a little titfucking? What then? Just imagine your cock in the middle of a GIGANTIC tit sandwich! She's so busty she's practically Brenda-esque!"

He gulped at that comparison. He could feel his penis stirring again.

She went on, "You should practice playing with those fun bags. Not only that, but she's probably gonna need a lot of cocksucking practice, and as a 'platonic' friend I'm sure you'll be more than happy to help her out with that."

She snorted and giggled. Even though she was jealous of Christine, those feelings were largely forgotten for the moment. She knew this kind of talk would increase his lust until he'd be putty in her hands, and that's what mattered to her at the moment, because she really wanted to get fucked.

Alan was instantly reminded of Christine's earlier busty teasing, which made him that much more aroused. Still he protested, "It's not like that. Really. I'd turn her down if she came on to me; it would be too dangerous."

Katherine snorted again. "That's a laugh. IF she came on to you? Where were you earlier tonight when she was about to launch herself at you? She was so horny, I could see it and smell it from the other side of the restaurant! Protest all you want, but I know you get off on danger. You say you hate it but you love it. Here you are..."

He replied, "I guess I can't help myself. You're too sexy. But if we're gonna keep going, could you please put your blouse back on? Loosely, at least?"

She looked at him indignantly. "Certainly not! In fact, I'm way overdressed as it is." Smirking with glee, she stood up and took off her short skirt. As she hung it on the same bar with the rest of her clothes, she said mirthfully, "As the famous saying goes, 'The best kind of fuck toy is a naked fuck toy.'"

He snorted with amusement, "Famous saying, huh?"

She tried hard not to giggle. She was trying to sound serious and academic, but failing miserably. "Certainly! Who said that? I forget. Winston Churchill? Mark Twain? Homer? One of those famous often-quoted guys, at any rate."

She suddenly stood up and sat down on Alan's lap so she could put her lips near his ear. She whispered quietly, "Here you are, in a public restroom having sex with your silly little sister while your absolutely gorgeous date is waiting patiently for you. Is that not naughty? Is that not truly dangerous? But you love it, don't you?"

As she talked she took his dick in her hand and stroked it as it steadily inflated between her legs. Giving up on frigging herself, she brought her other hand to his balls and began lightly scratching on the bottom of his nut sack.

He wanted to deny it, but the truth was in Katherine's hands, and in more ways than one. He just looked around as if he was able to see through the stall walls to see if someone was listening.

Katherine picked up on that and whispered as she stroked his penis back to life, "That's right. For all we know, there could be someone standing right outside this stall with their ear to the door. There's no way to know, is there? At any moment someone could stand up on the toilet seat in the stall next door and look over the wall down at us, couldn't they?"

He couldn't resist - he looked up towards the top of the stall, half expecting to see a face peering down. But no one was there.

Katherine was no fool. She knew that, at the moment, there was nothing more arousing to him than thoughts of Christine. If she was to get what she wanted and go all the way, she had to make him even more aroused first. She took a risk and whispered, "Heck, it could even be Christine watching."

He got even more visibly nervous at that. He also started panting hard.

But she quickly pressed on, saying, "Of course, Christine is very inquisitive. She'd want to learn what we're doing, just like she's 'learning' about flirting. We'd have to open the door and let her in. Then we'd strip her and teach her a thing or two about sex. Wouldn't that be fun? Just imagine a fully naked Christine standing here, watching you fuck your own sister! Her huge tits just wobbling and jiggling around as she bent over to get a really good look. Sure she'd be upset, but only because she'd have to wait her turn to get fucked!"

Seeing that Alan was panting and quite excited by her words, not to mention her stroking, Katherine turned around, held his erection in place, and slowly sat down on it. She let out a great big "Aaaaah" as it filled her up.

She was so tight that he couldn't enter her with one great thrust. Instead, they worked together to move her up and down, allowing her to take a little more of his erection with each down thrust.

Eventually, he bottomed out. He thought, Man, what a sister! She's so smooth and warm and wet. And so very, very naughty. How can I get mad at her when she makes me feel this good?

The two of them grunted with exertion as Katherine fucked her way onto her brother's shaft. After another minute or two, she relaxed and loosened up enough to make further thrusts a lot easier.

Even though both of them guessed no one else was in the men's room, they tried to stay as quiet as they could, just to be sure. In their nervousness the sounds of his wet dick surging and squishing its way in and out, together with the smacking of flesh on flesh, sounded like they were being picked up by a microphone and broadcast loudly throughout the room.

He felt excitement coursing through his body like an electric current. His mind boggled at the situation he was in, and his heart pounded wildly. He moaned, "Dammit, Kat, this is bad. Coming here, doing this. Jesus! I can't believe what a slut you are."

"Not a slut," she happily corrected him. "A fuck toy. Your number one fuck toy. A very naughty and uppity fuck toy, but one who knows just what you need sometimes even better than you do. And what you need right now is to nail some serious sister ass!"

They were both so carried away, they forgot about the danger of using words like "sister."

As she bounced up and down on him, going higher and higher with each new impaling, he complained, "I know what this is all about. You're jealous of Christine, aren't you? You're worried that she'll take your place somehow. Don't deny it, I've been getting those vibes from you for some time now. You always frown when her name comes up. You even admitted your jealousies to Xania this afternoon in her office. You've got to quit being so jealous."

Katherine didn't answer, all but confirming what he said with her silence.

So he continued even as he got more into the fucking, "Don't worry about it! I love you. YOU! NO one will ever take your place. Is that clear?" He possessively ran his hands all over her heaving breasts.

"No," she surprisingly said. "I mean, I know you love me in a non-romantic way and that you always will, but how can I compete when it comes to sex? I'm not as curvy or as stunning as all your other women. I have to try to make up for that by going all out."

He suddenly turned tender and the pace of the fucking changed too, slowing down. "Awww, Sis. You really don't have to do that. I'll love you and lust after you no matter what you do. Can't you see that? What do I have to do to prove it to you?"

"Fuck me!" she whispered in the most sexy voice imaginable. "Prove your love with your dick!"

So he fucked her some more, but now it really became more like making love. Instead of pounding her, he went slowly. He showered the back of her neck with kisses, reached around and slowly circled her nipples and clit, and nuzzled her ears. He wanted to prove the intensity of his feelings and tried to do everything he could physically to increase her pleasure. Before, his thoughts of Christine had increased his arousal, but now Christine was completely forgotten. He was so overcome with feeling for his sister that he practically cried, not from joy or sorrow, but just overall emotional intensity.

At the same time, he was going mad with arousal because Katherine was doing her utmost to fuck him to death, despite the slow pace. She put her heart and soul into it, moving her hips in ways that would make even a belly dancer jealous. She coaxed every last bit of pleasure possible out of her brother, gently and insistently grinding down onto him.

But while the slow fucking was intense and helped them reconnect, they were both too aroused and too worried about getting caught to go on like that for very long. Alan began picking up the pace.

He cursed the suit he was still wearing. He had been so distracted that he forgot to even take his jacket off and now it was both limiting his mobility and making him sweat. He feared going back to Christine looking suspiciously rumpled and sweaty. But he was still able to clutch Katherine's ass and knead her soft but firm ass cheeks. At the same time, he began bucking and thrusting his hips upwards with more urgency.

The slap of skin on skin seemed to loudly echo around the otherwise dead silent room.

Within minutes, he really started slamming into her. This was another way of proving his love, by overwhelming her with physical strength, fucking her harder and deeper than he'd ever fucked her before. Soon they switched positions and he began doing her doggy style so he could penetrate as deep as he could go. His erection banged past her cervix before sliding alongside and deeper into her with each thrust.

The two of them loved it. Both wanted to cry out, but had to restrain themselves because of where they were. Somehow, that made the fuck even better as the need to stay quiet constantly reminded them of the excitement and danger.

Alan waited until Katherine was overcome by a continuous, prolonged orgasm. Then he let loose, starting to fill her vagina with his seed. He could have gone on longer, but he kept thinking about that "do not disturb" sign and an employee coming in to see what it was about. He also remembered Christine, and imagined her impatiently waiting at the table. Thinking of that in particular really brought out his "Bad Alan" side. He reveled in how wrong it was to fuck his sister in the middle of a date with another girl.

Jet after jet of hot semen fired into Katherine's equally hot and needy pussy. For a brief moment, he enjoyed how great it felt when he didn't have to wear a condom. He thought of all his sperm swimming and struggling deeper and deeper into his sister, and was reminded that there was always a chance the protection would fail and they would make a baby. In his overheated and lust-addled brain, that thought just aroused him all the more.

She was thinking along the same lines. Gaawwwd! Wouldn't it be sweet poetic justice if he banged a baby into me while on a date with Christine? I don't know why that would be so perfect, but it really would! For one thing, it just goes to show what a total fucking tamed sister slut I am! Hee!

Don't stop! Don't stop now! Keep filling me with your precious baby batter! Bang your sperm straight into my womb! ... Oh dammit, he's slowing down... Shoot, we're down to the last squirt. But still, what a RIDE that was!

The two of them ended up in an embrace. They were a sweaty, disheveled, and panting mess. Even now, he kept his jacket on, since he didn't have any good place to put it (the bar holding his sister's clothes wouldn't work for his stiff jacket).

Between the need for speed and his great excitement, he had cum in a matter of minutes since they started the hard and fast thrusting. That was a poor performance compared to his recent standards, but at least he knew that he'd been completely satisfied and his sister was completely satisfied too.

Katherine couldn't help but gloat a bit. She was the first to speak as she sat on him sitting on the toilet and they both recovered. She crowed, "So. Still thinking my coming here was a bad idea?"

"Okay, you got me. It was fun. A lot of fun. And I feel good that we reconnected in a primal way. I'm sorry if I haven't spent enough time with you lately. But I still think this was a bad idea overall. We risk everything for a few minutes of fun. Promise me you'll keep to your promise and not do this kind of thing in public again. Especially not when Christine is at all involved."

Katherine pouted. "As Mo- as Susan would say, 'Oh poo.' But I suppose you're right. Okay, I promise."

But inwardly, she was far from regretful about what she did. She knew that she had accomplished her main mission. When she'd come to the restaurant, she'd been able to detect sparks flying between Alan and Christine even from across the large room. True, Alan seemed surprisingly determined to keep things platonic with his bombshell date, but when he got that aroused lately his little head usually overrode his big head. Now, after two climaxes to top off an extremely sexually busy day, she knew it would be a near miracle if he could even achieve another erection. Just as importantly, the momentum of his date had been lost. Katherine felt confident that the Christine "threat" had been neutralized, at least until their next date.

Alan had stood guard and successfully made sure that Katherine could escape the men's room without notice. The only curious thing was that he couldn't take the "do not disturb" sign down because someone had removed it already. That led both him and Katherine to wonder if anyone had come in to check if anyone was there, but if someone did they had no way of knowing. They also did not know they had just missed Christine's exit from the ladies' room by a couple of minutes.

In retrospect, he realized that both he and Katherine had used words like "Sis" and "Sister" a couple of times. That worried him more than anything. He doubled his resolve not to let his lust overwhelm his common sense ever again, because the risk of losing everything was too great.

He went to great lengths to wash and clean himself before he left the bathroom. Luckily, his hair was unruly most of the time anyway, so his slightly bedraggled appearance wasn't so noticeable.
