Summary: PWP Smut, Post Ep "Way To Go".

Greg didn’t know how it had happened – he had never meant to get involved with his boss. He assumed it was the whole thing with Brass – Greg could tell it had really messed with Grissom’s head.

But he never expected anything to happen so fast.

He really didn’t foresee Grissom pulling him into a bathroom after Brass had woken up. He didn’t know that ‘keep talking’ meant ‘follow me into the bathroom so I can fondle you.’

But that was what had happened. Greg was having a seemingly normal discussion with his boss when Grissom ducked into a bathroom, telling Greg to follow him into the multi-stalled room so they could continue their conversation.

Greg had walked past Grissom, continuing his chatter when he heard the click of the lock. He looked back at Grissom – just for a moment, before the older man shoved him against he sink so hard that Greg knew he would have bruises on his thighs the next day.

“Griss?”

The only response that Greg felt was the pressure on his dick – it was Gil’s hand.

“I’ve watched you so long, Greg – watched you grow – watched you become the man you are today,” he whispered hotly into Greg ear.

Greg swallowed. “You have been a part of that, sir.” He was still confused by the hand that was on his rapidly hardening member.

“I want you,” Gil said solemnly, looking Greg directly in the eye. “I’ve always wanted you and now, I’ve realized life is too short.”

“I… I don’t… know… you…” Greg tried to sputter out a coherent thought.

“You don’t have to do this because I’m your boss.”

“No, I just… I didn’t know.” Greg thrust his hips forward to gain more friction against Gil’s hand. “I just… you know my favorite fantasy?”

“No,” Grissom said idly as he undid Greg’s top pant button.

“I think about you fucking me over your desk. I even use this dildo that I bought just for this fantasy,” Greg panted out as Gil reached inside his fly and grasped his dick. Greg was glad he hadn’t worn underwear. “I put it in me, and I… because you do this thing…” He moaned as Gil continued to stroke and pull on his engorged penis.

“Tell me what I do to you, Greg. Tell me what I do in this fantasy of yours.” His voice was calm and collected, but his dick was straining against his pants.

“You bend me over, and you tell me that I have to do this or you’ll fire me. But, I know… I know you’re messing with me,” he gasped as Gil put pressure on the slit of his cock. “You lube me up with a vial from one of your shelves – I don’t even know what it is, but you stick it inside me with your fingers. Then you line up and thrust in…” Greg moaned and panted between words as Gil picked up the pace of his hand. “And you fuck me over your desk… and you grab my… UHHH!” Greg shouted as he came over Gil’s hand.

Greg sagged against the sink, looking at Gil through half-lidded eyes. “What…”

“Come to my place…” Gil whispered as he washed his hand in the sink and then grabbed a wad of paper towels with one hand. He pulled out his own dick from its confines and started to fist it furiously.

“Gil?” Greg asked, trying to reach out.

“It’s okay – you just enjoy. I’ve got… things… to… uh fuck… do.” Gil took one last look at Greg before he came into the paper towel he was holding in his hand. He sighed deeply and relaxed.

Greg took the paper towel and licked at it. “I’ll be waiting there.”
