Like so many of life's stories, this one started out due to a conflagration of random and unexpected events. Event one was Mr. and Mrs. Smith's decision to reconfigure the upstairs of their home given that the kids, Dan and Amanda, had gone off to college for their final years. Mr. and Mrs. Smith had reached the conclusion that the kids' final years in college would mean that they would be moving on and moving out, welcome back on occasion for long weekends. Mr. and Mrs. Smith had discovered that having the house to themselves made for much more in the way of sexy time, and Mr. Smith's recent discovery of the joys of Viagra had led them to new heights in the sex department.
With that in mind they decided to change the overall vibe of the upstairs. The thinking, primarily by Mr. Smith, revolved around the idea of converting the two upstairs bedrooms into other uses, and converting the two bathrooms, formerly adjacent to those bedrooms, into a one big bathroom spa, which would be used primarily by Mr. Smith in the pursuit of amorously plundering Mrs. Smith at every opportunity. So they turned one bedroom into his office, the other bedroom into her office, and the bathroom into a kind of destination love nest. There was a jacuzzi perched on a ledge in one corner, a walk in shower on another corner, a steam room in the third corner, and two sinks on opposite ends of the bath. Two toilet rooms were designed with total privacy in mind, they were only accessible from each bedroom, so the bath was just for luxuriating and having lustful sex, which they did manage to do, in nearly every imaginable way and in most every corner. Like Mrs. Smith sitting atop Mr. Smith in a suds filled bath while he licked suds off her tits. Or Mr. and Mrs. Smith giving each other oily hand jobs in the shower while he kissed her tits. Or like Mr. Smith bending Mrs. Smith over the sink and plowing her while he fondled her tits. Or Mrs. Smith giving Mr. Smith an epic sweaty blow job in the steam bath, while he thought about how nice it would be to be sucking on her tits. Now would be a good time to clarify that Mrs. Smith had exceptionally nice tits.
Mr. Smith had even foreseen the wisdom of mood lighting and a stereo sound system, which was generally set on smooth jazz, though when he had Mrs. Smith bent over at the sink fondling her tits he did opt to crank some energetic heavy metal. The new bathroom quickly became known as the sex bathroom, as in "hey, what do you think about visiting the sex bathroom tonight?"
Event two was that shortly into the spring semester of 2020, not months after the completion of the sex bathroom and not near long enough for the novelty and energy of the sex bathroom to wear off, Covid shut down the college and the kids had to come back home. So Mr. and Mrs. Smith had to frantically convert the two upstairs rooms back into bedrooms and dismantle as much of the sex element of the sex bathroom, which was now to become a shared bath between siblings, much to the significant dismay of Dan and Amanda, not to speak of Mr. and Mrs. Smith. Dan and Amanda tried to make the best of it, creating a set of casual rules and rough scheduling, which led to some less than casual arguing and some more strident rules and scheduling. The most significant rule revolved around door locks, so that when one person was using the bathroom, they would lock the door adjacent to the other person's bedroom. Of course that led to Amanda and/or Dan forgetting to UNLOCK said adjacent door, which led to yelling and/or causing the locked out victim to stomp around the upstairs to get access through the guilty door-locker's room.
Event three occurred a few weeks into the sharing of the formerly sex bathroom, on a day when Amanda thought Dan was at his weekly morning tennis match, and Dan thought Amanda was at her weekly outdoor covid-safe yoga session. Unbeknownst to either, Dan's weekly tennis match had been cut short due to his playing partner's stomach issues related to last night's Mexican food and more specifically tequila, and Amanda's covid-safe yoga session had been cancelled due to the yoga teacher catching covid due to some covid-unsafe activities with her landlord, who's wife was just sharp enough to connect those two dots. All that led to Amanda being in the bathroom with the door left unlocked, and Dan barging into the bathroom like he owned the place. Which would have been ok, except that Amanda was casually dressed in what can only be described as a very revealing and very pink bra and panty set, which caused a significant processing delay for Dan, in that he was shocked and surprised to see his sister in the bathroom, was shocked and surprised to see that she was half naked, and was shocked and surprised at how good she looked in pink underwear.
Amanda, on the other hand, had a much shorter processing delay.
"What the fuck Dan!" she shouted, making a weak attempt to cover herself up from her mouth gaping brother.
"Oh shit, sorry sis," he stammered, collecting himself from his shock and surprise enough to turn away in embarrassment and stumble back out the door.
It was a five second moment, a flash of vision and circumstance, but the impact was heavy. Back in his room, Dan collected his embarrassed wits enough to realize that he was hardly at fault, that she had left the damn door unlocked and even ajar, maybe even that he had apologized too quickly, which led him to inject a verbal protestation on how unjustly he had been treated, which led to another response from his still shocked and embarrassed sister that included a few more f-bombs.
Dan chose to continue to retreat from the situation and sat back on his bed, where he spent some time trying to contain his rising indignation, some time to consider mitigating the dispute, and a lot of time thinking about the image of his sister in her underwear. It had only been a flash, but like a nude scene from a movie he kept replaying it in his head, watching her turn towards him in slow motion and her mouth coming open in shock, while his eyes slowly traversed the area from the top of her feet to her hairline, all of which involved a lot of skin. His mind couldn't help but embellish, creating even more exposed skin, even more slow motion.
Meanwhile Amanda was still red faced and half naked at the sink, angry that Dan had barged into the bathroom, angry that she had been so stupid to have not closed the door, angry that he had seen her naked. But somewhere in all of that she was flustered and for some bizarre reason aroused on some level when she thought about him looking at her half naked body. Which made her even more angry.
Now would be as good a time as any to mention an extremely important angle to this story. Dan and Amanda were two people extremely well blessed by genes. To say they were both attractive people would be a significant understatement. What they were was ridiculously hot, the kind of people that turn heads no matter where they went. Dan was just over a year older, but all of his friends would initially go catatonic when they saw her for the first time, and Amanda's friends would become blathering idiots when they laid eyes on him. They were so attractive, in fact, that it was impossible for even a sibling to ignore the fact. As siblings they weren't actually hot for each other sexually, but in terms of appearance, they had to admit that it was hard not to look, and harder not to look approvingly.
This would also be a good time to point out a few other nuances related to the hot thing. Both Dan and Amanda were extremely attractive seniors in college, where just a month ago they had been spending a lot of time in very social and often sexually charged settings with loads of other attractive college aged kids. Amanda had just started dating a strapping young soccer player with a fairly endless appetite for wanton sexual adventure, and Dan had been dating not just one but two stunning young women. One was blonde and one was brunette, and both were smoking hot and so sexually liberated that when they found out that Dan was two-timing them, they decided that was ok and scheduled themselves accordingly. They even went so far as opening up the discussion as to possibly meeting for a romantic interlude on the same night, which led to a three-way chat on how that three-way might evolve, even how certain positions might be enjoyed. For example, there was a lengthy discussion on how the blonde might be perched atop Dan's cock, while the brunette was perched atop Dan's face, and whether or not the blonde and brunette might be kissing while that was going on. Or whether the brunette might consider going down on the blonde while Dan was fucking her doggy style. Or whether the brunette might be inclined to lick on his cock while he was fucking the blonde. All of which was very, very much ok with Dan, who was near ecstatic at the prospects of enjoying his first threesome, which they did indeed actually schedule. Unfortunately they scheduled the event for the Friday night that coincided with the evacuation of campus due to Covid.
So considering that Dan and Amanda had gone from those lofty heights of social and sexual activity to the dismal depths of quarantine and sharing a bathroom with a sibling, there was a considerable amount of anxiety and sexual frustration with absolutely no direction to take it.
