It Ain't Zumba
Duo wasn't paying any attention to the instructional DVD playing on the TV or the vaguely Spanish music playing from the speakers. He just simply stood there and watched Heero move in time with the woman on the screen, his skin glistening with sweat as he did what Duo would have called the samba, but it really wasn't—Duo was a mobile suit pilot, not a dance expert. Duo wasn't gawking because Heero was good at doing this sort of exercise program—the Rumba or whatever Heero said it was—but simply because Heero, unlike most people, never wore sweats when working out. He opted, instead, for his usual shorts and tee shirt combo.
Watching Heero do some sort of belly dance thing from behind in those shorts while covered in sweat and in a muscle tee was something Duo didn't even know could happen with Heero full-stop, let alone occur right in front of him. So of course no one could expect Duo's eyes to be paying attention to some woman in a sports bra and yoga pants when there was something so much better right there two feet in front. Thank god he was wearing sweat pants and they weren't at a community class or something.
"Why aren't you following along?"
Duo jumped. He hadn't realized Heero was actually watching him. He snorted.
"You expect me to be able to pay attention to something when you're two feet away from giving me a lap dance?"
Heero made a noise Duo had never heard before; he wanted to hear that noise again, wondered what would cause something like it…
"Especially—" Duo lowered his voice, closed the distance between the two of them. "—when you're in shorts like that and covered in sweat and all I can think is, 'God, I wanna fuck that.'" He rested his arms on Heero's shoulders, ground a hip into his as a hint of what was coming next.
"I know a better way to sweat our asses off, and it's way more fun than this mambo shit."
"Zumba," Heero corrected, before nipping at Duo's ear.
"I don't give a shit what it's called," Duo said, as he pulled Heero to the floor. "But I know what we're about to do is called…and it ain't 'zumba'."
