A/N: For Cylina Nightshade, who requested #44: "I got the mirror so you could see yourself while I'm fucking you." I decided to go with 1x2x3

Warnings: language, sex

Pairings: 1x2x3

It was Wednesday, which meant Heero and Duo got off work early. It meant Duo brought Heero back to his apartment and undressed him on the way to the bedroom. It meant Duo teasing Heero, promising a slow, hard fuck as he nudged Heero closer to the huge, four poster bed that seemed so incongruous in the otherwise simply-furnished bedroom.

But Duo had chosen the bed frame for a reason. Not just its size - a kingsized bed that, he joked, was bigger than the cabin he had been assigned aboard Peacemillion when he crewed on the ship after the war. But because the posts, one at each corner, were perfect for tying Heero up when the mood struck him.

But it was Wednesday, and Duo didn't tie Heero up on Wednesdays. That was Thursdays, sometimes Fridays, and one very memorable Tuesday.

When Duo pushed Heero back onto the bed, palm on his chest, just over his heart, and a sensuous smirk on his lips, Heero looked up.

"I got the mirror so you could see yourself while I'm fucking you."

Heero shivered at the words, at the promise in Duo's eyes.

Duo loved the way Heero looked during sex, loved his loss of control and the look of wonder in his eyes when he came.

"You're so fucking beautiful when you fall apart, Ro. You have to see it."

Wednesdays were for making love, more than for fucking, and it was the night that Heero and Duo had to themselves, just the two of them.

Except for this Wednesday, when Trowa had agreed to trade shifts with another agent and forgotten to tell them.

So this Wednesday, when Heero's ass was full of Duo's cock and Duo was enticing Heero to open his eyes and look at himself, Trowa walked into the bedroom and startled them both.

Heero looked guilty, started to crawl away until Duo latched onto his thighs and held him in place.

Duo, though, met Trowa's gaze and arched an eyebrow in question.

"Traded shifts," Trowa explained, looking at the sheen of sweat on their perfect bodies.

Duo nodded, the explanation enough for him, and his questioning look turned into one of invitation.

"Wanna join?"

Mondays and Saturdays, those were Trowa's nights with Duo, when it was just the two of them and things were like before - before Duo had invited Heero into their bed. Tuesdays, Thursdays, Fridays and Sundays - those nights they shared Duo. Trowa and Heero carefully navigating the limits of their desire, their need to be the singular focus of Duo's lust and the knowledge that he would rather have neither of them if he couldn't have both.

The divided nights - one for Heero, two for Trowa - had been Duo's sole compromise on the issue.

There had been so many missteps, over the seven months of this arrangement. So many times when Duo had grown fed up with the both of them and walked out and told them to work out their shit. Trowa had left, as well, a few times - not just walking out on the sex, but packing a bag and running away, joining Cathy at the circus for days, once for weeks. Heero never left, had only ever scooted to one side and listened while Trowa called Duo awful names and Duo glared back but remained silent, let Trowa empty out the poison of his own self-doubt.

Trowa looked past Duo, to Heero. After all, this was his night. His one night.

"I'd like that," Heero said after a long moment, almost too long.

But then Duo was grinning, was telling Trowa to get undressed and get his cock ready, because the sight of Trowa fucking Duo, while Duo fucked Heero, was going to be gorgeous.

And it was, Trowa had to agree, as he arched his back and looked up at the mirror, as he met Heero's gaze in the reflection. As their hands met over Duo's thighs, holding him together for the first time.
