Danny moaned wantonly, pressing back against the steady force of the body behind him. The tight grip on his hips kept him from gaining any kind of control, licks and nips at his neck and below his ear stopping him from being able to form a coherent thought. The only sounds in the room were Danny's moaning, the slap of flesh against flesh and the occasional dirty whisperings in Danny's ear, the filthy promises falling from Flack's lips between hard thrusts. After a series of particularly hard stabs against his prostate, pleading curses echoing in the room as Danny felt the heavy tingling in his nerves build and build, the blond stiffened, Flack's fingers at his hips tightening as far as to leave bruises on the sharp bones.
Danny shook through his orgasm, purring low in his throat as Don kept going, fucking into his tight, constricting heat as Danny spilled against the wall and sagged back against the other man's strong chest. "So fucking good, Kitten." Flack bit down on Danny's ear, eliciting a sharp gasp from the CSI. "Don't you think, Mac?" Don turned his head to face the man, smiling wickedly as Mac just sat there in his seat, behind his desk, watching the pair as Danny slowly came back to himself. Don kept his eyes locked with Mac, even as he continued his assault on Danny's body, jerkily thrusting into Danny's body, seeking his own release.
Don groaned loudly as Danny pressed back to meet him, his inner muscles clenching as he coaxed Don along, trying to get the other man off. "Fuck, that's good." Don muttered, eyes falling shut, as he pressed tighter to Danny. There was the scrape of a chair on the floor, Mac walking from his desk to stand behind Don. Mac's clothed erection pressed against Don's ass, the elder male pulling both his lovers back against him. Mac's hands travelled up Danny's bared chest, tweaking at hard nipples painfully and causing him to jerk back against Don, making the Detective moan at the sensation. "So close," Don murmured, lips pressing against Danny's neck. "Jesus, I'm so close." Danny whimpered and leaned his upper body forward, his head resting against the wall and Mac could see that his protégé was getting hard again, Don's continued fucking sparking arousal in the other man all over again.
Mac used his own body to pin Don, his hands pulling at Danny's hips, controlling their fucking and pushing his own cock against Don. It was when Mac bit down on Don's neck that the man finally felt his release spread through him like wildfire, a low drawn out groan from Don as he climaxed and a small, almost desperate whimper from Danny. "I think we need to take round two home, don't you?" Mac smirked against Don; hands petting gently over Danny's chest before he slowly pulled back and allowed them both to pull their clothes back together.
