Passion
Bond kissed him gently at first, he wanted to be sure this was safe. He could feel Q's impatience in the kiss and smiled into the younger man's lips, begging the Quartermaster to be the one to deepen it so he didn't have to break away and ask permission.
Q wasn't sure how he had ended backed up against his office door, he knew he had pulled on Bond's shirt, but he had also felt the weight of the double-oh-agent pushing him as well. Either way, he liked the power Bond had over him and was unwilling to let this end any time soon. The younger man picked up the pace as his hands left Bond's shirt and grabbed at the back of the double-oh-agent's neck, deepening the kiss. Bond moaned into the kiss and grabbed Q's arms, pinning them to the side of the younger man's head, his mouth traveled from Q's over his chin and down to his throat.
"James…" Q had murmured the double-oh-agent's name to the silent room, while Bond continued his assault on the younger man's neck. Q felt Bond pushing him from their position against the door towards the desk. The younger man turned them and sat on the desk with his legs wide, pulling Bond closer to his body.
Bond lips smashed against Q's again with more passion, one hand around the younger man's waist, the other grabbed his left leg and hitched it up his side while Q clutched at the double-oh-agent's hair, uncaring to the paperwork he was perched on.
Bond pressed himself against the younger man and Q moaned into the kiss, this feeling being what almost drove them to the edge. "Perhaps," Bond whispered, not being able to let his lips leave Q's for longer than necessary, "perhaps we should continue at your flat."
"You're probably right." Q whispered back to him, breathless.
They stood up and manoeuvred themselves towards the door, still embracing each other, hoping that they could keep themselves away from each other to make it through the hall towards the elevator, where they would get their fix on each other again.
During the ride to Q's flat, both bite their lips to keep their passion a secret. The younger man could feel Bond's heated gaze on him, and Q knows he's end backed up against another door as soon as the double-oh-agent had the privacy to overpower him again.
