Genma held excruciatingly still for half a second, letting shivers wash through him at Raidou's touch. Slightly hesitant, inquisitive at first, and then... Gods, yes. Then more sure. Raidou had big hands, bigger than Genma's. His fingers were hot and slightly rough, and Genma groaned again, rocking up to meet them.

He slid his hand down the back of Raidou's jeans, pushed his own fingertips under the crinkled elastic of the waistband of Raidou's boxers. Caressed the hint of hard-edged spine and the tiny collection of downy hair in the small of Raidou's back. Pushed lower to stroke the curve and hollow of Raidou's ass, all toned muscle and sweat-slicked skin.

Instinct had him lifting his sling-bound arm for half a moment. Just long enough to realize it was impossible, to send a flash of irritation through him, to turn a groan into a growl. Raidou reacted with concern, face hovering over Genma's, hand stilling. "Fucking sling," Genma complained, and lunged into another kiss, crashing lips and teeth together hard enough to hurt. Just a little. Just a little pain to convey urgency. Eagerness. It could have been calculated, could have been an eros trick, but it wasn't. Artifice could mimic passion, but this was the real thing.

Genma's hips lifted again, and his hand on Raidou's ass pushed, pulled. He could feel the tension in Raidou's back, the strain as Raidou held his body carefully away. Millimeters away, so close that every breath brought them into contact. Raidou was hard--how could he not be?--but Genma could feel it, brushing his hip. Raidou wanted this.

That in itself was the hottest thing in the world. Genma gasped a breath, rolled his hips again, and slid his hand all the way into Raidou's pants, groping for the back of Raidou's thigh.
