Tonight began as anything but a typical night for Greg Sanders. It began with his first autopsy, seeing a body cut apart and laid out before his eyes was a strange experience. It wasn't what he expected, he didn't feel ill nor did he puke. It all seemed so unreal and weird. Grissom seemed pleased at his reactions, and almost proud.

Greg had been stuck back in the DNA lab again since Chandra bolted. He wanted to get back into the field but first he needed to find a replacement. Now here he was, standing in the mens room holding a bucket. Grissom has had him do some weird things in the past but this was the weirdest. He was about to take a dump in a bucket in the name of science! His boss would go to just about any length to solve a case. Like the time he infected Greg's feet with mildew. Greg had resorted to withholding sex for four days (which, for Greg, was not an easy task) until Grissom apologized. The make up sex that followed, though, was well worth it.

After shift Grissom informed Greg that he should go home without him, because as usual he had to work some overtime. He promised to be home as soon as he was able, which could be anywhere from a few hours to an entire shift. Knowing this, Greg stopped for a quick breakfast and a bit of grocery shopping before returning to the townhouse he and Gil shared. He turned on the computer and checked his e-mail and surfed the web for awhile and then decided to take a quick shower and get some sleep.

By the time Grissom returned home Greg was finished with his shower and was standing at the sink drying his hair, wearing only a towel. Gil stepped into the bathroom and smiled, he loved the sight of a freshly showered Greg. He moved until he was standing behind him and wrapped his arms around his waist. Greg smiled back at him though the mirror.

"Mmmm, you smell so good, my boy." Gil whispered. "Miss me?"

"I always miss you." Greg answered.

"That's good to know." Gil said snuggling closer, kissing him lightly on the cheek.

"Did you miss me, too?" Greg asked with a smile.

"I couldn't wait to see you." Gil said, his voice growing deeper.

"I can tell." Greg smirked, feeling Gil's erection against him.

"You know, I still think you need that prostate exam I mentioned before." Gil reminded him.

"Gil, I told you, my prostate is fine." Greg argued. "Don't need to see a doctor."

"Well, I was hoping to examine it myself." Gil said a little breathless.

"But you're not a doctor." Greg pointed out.

"I have a PHD, so technically I am a doctor." Gil joked.

"I see," Greg chuckled. "So you want to play doctor then?"

"Oh yeah." Gil said, "You might say that."

"I haven't played doctor since I was fifteen, with my neighbor Suzy." Greg told him.

"Tell me about it." Gil said as he held Greg tighter.

"Not much to tell, her father walked in right in the middle of the breast exam."Greg recounted.

They laughed at this. That was one thing he adored about Greg, he always made him laugh even when he was feeling the like his whole world was ending. He always knew what to say to make it better.

"So then what happened?" Gil said still laughing.

"He kicked me out, then called my parents. They grounded me for two weeks." Greg recalled. "For practicing medicine without a license."

"That's very funny, Greg." Gil smiled "Did you learn your lesson?"

"Nope." Greg said almost proudly. "A month later my my mom walked in when me and my friend Jason were studying in my room."

"What were you studying?" Gil asked already guessing the answer.

"Each other!" Greg admitted. "That's when my parents discovered I was Bi. Was grounded another two weeks."

"So, you stopped playing doctor?" Gil inquired.

"No, I just stopped getting caught." Greg said bursting into laughter.

"You don't have to worry about us getting caught." Gil said caressing the front of the towel Greg was wearing."I'm going to give you a thorough examination. Inside and out."

"I can't wait." Greg said sucking in his breath.

"First, let's remove this towel." Gil suggested, unwrapping it from Greg's waist, letting it fall to the floor. He reached down and palmed Greg's cock, stroking it slowly.

"Oh God Gil," Greg moaned. "that feels so good."

"Looks like you have no problem with erectile dysfunction, you respond very well to stimulation."Gil said breathlessly.

"I respond to you." Greg groaned.

"Greg, I believe your heartbeat has increased, and your breathing is a bit heavier as well." Gil said as his own breathing mirrored Greg's.

"Is that good… doctor?" Greg said clearly enjoying this game.

"Oh yeah...very good." Gil said as his desire increased. "I believe it’s...time for the...internal exam."

"Please do." Greg panted.

Gil reached into the medicine cabinet and retrieved a bottle of lube, which he opened and spread onto his fingers. He instructed his patient to brace himself against the sink, move back, and spread his legs. Greg eagerly did as instructed.

"That's my good boy." Gil grunted, he wanted Greg so badly now. "Tell me if it hurts."

Greg moaned as a finger was gently inserted into him. Gil hesitated then pushed in further, changing his angle. Searching for that bundle of nerves he knew would drive Greg wild.

"Tell me...when I reach...your prostate." He bit his bottom lip in an effort to stay in control.

"Ohhh God!" Greg cried out. "You reached it!!"

Gil inserted a second finger and began moving them in and out of Greg's hole, brushing against the area he had been searching for, again and again. Greg squirmed at his touch and pushed back against his fingers.

"I believe your prostate is fine Greg," Gil said still playing his role. "But I need to probe you deeper just to be sure."

"Yes...please, doc...please," Greg gasped. "Gotta be sure."

"I believe I have just the right instrument for the proper... penetration." Gil growled opening his pants.

After quickly pushing his pants and briefs down to his ankles, he took the lube and coated his aching cock. He could hardly wait to be inside Greg, and fuck him with everything he had. Hard and fast just like Greg loved it.

"Greg..." Gil paused to catch his breath. "I'm going to insert a rather large, hard probe into you, so relax."

"I'm ready, doc." Greg looked back at Gil, a look of pure lust in his eyes.

Greg waited, bracing himself against the sink. He loved it when Gil played dirty little sex games with him! Usually it was he who initiated them, and it was a rare occurrence when Gil did, but when he did he was really into it. It was a side of him that only Greg had the pleasure of knowing. Greg sucked in his breath as he felt Gil enter him slowly.

"There." Gil said pushing in deeper."That doesn't hurt, does it?"

"No...feels good...don't stop." Greg pleaded.

"My God, you...are so...tight...my boy." Gil moaned "Tell me...when I reach..." Gil couldn't finish, he was so overcome by Greg's tight heat enveloping him as he pushed in deeper.

"Oh fuck!" Greg shrieked. "That's it, doc...keep going!"

Gil held on to Greg's shoulders and he pushed into him, slamming deep into him, then pulled out slowly only to slam in again, over and over. His angle was perfect, striking Greg's bundle of nerves with every stroke, driving Greg and himself wild, Greg pushed back to meet his every thrust.

"Oh Gil...yes! Yes! Fuck me...harder...feels so good!"

"Oh Greg...my beautiful boy...love you."

"Love you...too. Oh Jesus...Yes...more! More!" Greg begged.

"Anything... you want...God you feel...so good." Gil groaned as he pounded into Greg.

"Love feeling...your cock...inside me...oh God, Gil...oh fuck, yeah!!" Greg thew his head back and moaned loudly, white sparks flashed behind his eyelids.

Increasing his pace, Gil fucked him furiously now, moving his hand to once again fist Greg's erection. He pumped into him relentlessly, his balls slapping against Greg's ass. Sweat formed and dripped from Gil's body and onto Greg's back as their bodies moved as one, their passion consuming them.

"Fuck yes!" Greg nearly screamed. "Fuck me...Gil! oh God...fuck me!"

"Greg...Greg...love fucking you...you're all mine." Gil cried as the world disappeared and only he and Greg remained.

"I'm yours." Greg breathed heavily.

Greg's body trembled with pure pleasure, more sparks flashed like fireworks behind his eyes as he neared his release. He felt it coming, that familiar tingling in his gut, straight to his balls. He could hold back no longer. Gil felt it too, he was on the edge, all control vanishing.

"God...Gil, I'm...gonna cum!"

"Cum for me...Greg...cum with....me!"

Greg cried out as his orgasm swept though him, spurting his juices right into the sink bowl. Gil felt his lover's body clench around him and his release hit as well, spilling his seed deep inside Greg. Gil collapsed back against the bathroom wall, pulling Greg with him, both sliding down to the floor. They sat together trying to catch their breath, after such intense orgasms. Gil held him close, as Greg lay is head back on Gil's shoulder. After a few moments their breathing returned to normal, but they remained where they were, not wanting to move.

"I've never played doctor quite like that before." Greg admitted, smiling.

"I'm glad you enjoyed your examination." Gil smiled back at him.

"I might have to make another appointment." Greg smirked.

"For you, Greg, the doctor is always in." Gil laughed at his own joke and Greg joined in laughing, too.

The End
