If Minami were more practiced at this or more hesitant, all of this would vanish. But him warm and unthinkingly eager in his lap is causing everything to short circuit and go sideways, turns everything to reactions. Hand dig into his hair and his hands dig back into hips and he's dragging Minami down in his lap harder, pushing him just a little until the angle is a little better...

It's a thin line between something that's making out and something that's really more sex with their clothes on, and Yuuri's the one that pulls them right up to it, cocks grinding against each other's through their clothes. And words are complicated but noises are easy and he's meeting Minami moan for moan, doesn't let his mouth get far from his, or from his skin, half to muffle himself and half because he doesn't know what words might spill out.
