Alec smiled at the words, not finding them ridiculous at all. "As you command." He said, referring back to Magnus's earlier comments of jailer and prisoner. As Magnus leaned back to accept him, Alec released his boyfriend's manhood and let his own hips slam forward, driving himself deep inside the other man. "Oh god, Magnus!" he exclaimed at the intensity of the tight heat that completely sheathed him. His fingers gripped Magnus by the hips fiercely though he let the man move at his own pace. Waves of pleasure rushed through his body causing a light perspiration to break out over him.
Each movement drove Alec closer to climax, and the closer he got the more desperate his gasps and moans. Suddenly, Alec leaned against Magnus to push him forward on his hands and knees again. He followed so that they remained pressed together, sliding his hands over the smooth brown skin of the warlock's body. He kept his hips angled so that he could still stimulate his lover's prostate with each thrust, driving Magnus to his release. The position also still allowed Alec to trail kisses, nips, and slow sucking bites along his neck, shoulders, and back. He gasped Magnus's name and ecstatic curses of pleasure into his ear, groaning breathlessly with each thrusts. "Magnus.. by the angel.. so tight.. amazing... fuck." Alec struggled to articulate just how much he was enjoying this, but wasn't great with voicing his feelings even in the least exciting situations.
Giving up the endeavor to put words to his pleasure, he decided to attwmpt to commuicate through his body. Alec changed his pace to buck his hips forward to meet Magnus, deepening each thrust as much as possible. Replacing his hands upon Magnus's member, he matched the rhythm of his touch with their hips so that the two sources of stimuli complimented each other, pushing Magnus- thus them both- closer to climax. He hoped that Magnus understood what he couldn't articulate verbally- that Alec cared for him and wanted to please him.
The realization of how much he cared for Magnus hit him in the gut, the warmth spreading through him. He still felt it was too new to call love, but here he was putting Magnus before himself, getting off more to his boyfriend's pleasure than his own.
