Greg lay on his bed and bemoaned the current state of his life. He had failed his proficiency, and his replacement had scarcely made it through one shift before quitting. And to top it all off, Greg knew that Gil was disappointed in him. He had resigned himself to sleeping alone when he heard a knock at his front door.

Greg got up and looked through the peephole. There was Gil, holding an overnight bag.

"Greg, I know you're in there. I heard you come to the door. Now get away form the peephole and open the damn door."

Greg opened the door, stunned. He was even more stunned when Gil grabbed him by the dick and demanded he make his way to bed. Greg followed the command and lay on the bed.

"No, face down. You've been bad."

Greg knew he had better do what he'd been told.

"Arms over your head, face in the pillow."

Greg did so and felt Gil snap his right wrist into a cuff. After leading the chain through the headboard, his left wrist was given the same treatment.

"Ass up."

Greg was relieved to be able to take his weight off his now hard cock. He felt Gil pull of his socks and shoes and then reaching up to take off his jeans and boxers in one motion – but the quickness of it all had left him lying flat on the bed again. He was torn between not moving and putting his ass up when he heard a thwap and his ass lit on fire.

"OW!"

"No talking!" The paddle came down again. "I told you to put your ass up. I never said you could put it down!"

Greg moved back onto his knees. He was in pain, but he was more interested in where the paddle had come from – he had never seen it before. In fact, Gil had never even talked about wanting to do something like this.

"You want me to stop – really stop – you say ‘horse'. Understand?"

Greg was too afraid of the paddle to speak. He felt Gil's weight come down on the bed and a hand on his shirtsleeve.

"You may speak. Do you understand?"

"Yes."

Thwap. Greg bit his lip to keep from crying out. "That's yes sir!"

Greg held back a whimper, he didn't know the rules, so why was he being punished for when he didn't know what he was doing wrong? He felt Gil's weight move down the bed and then wetness on his enflamed ass as Gil covered it with open mouthed kisses. The beard scratched painfully on the battered skin.

Gil moved again so that he was sitting on Greg's shoulders and pinning him down. A dry finger ran down Greg's crack as the other hand held open his cheeks. The finger teased his entrance.

"You made a very bad mistake at work today. Contaminated a scene – made me yell at you. I hate to yell at you," he said, pushing the dry finger inside Greg. "Fuck, you're tight."

Gil removed the finger and got off of Greg. Greg heard him rifling through the overnight bag – the same bag where the paddle must have come from. The hand came back and spread him open and there was a shock as cool liquid made its way into his crevasse. Gil settled between Greg's legs and began licking the younger man's balls. Greg bit at the pillow to stop any sound that would bring back the paddle. The tongue continued its journey up, past no man's land and to Greg's hole. Gil pulled Greg's cheeks apart to the point of pain and began to jab into Greg with his tongue, and Greg could no longer stifle the moan that escaped his lips.

Then Gil was gone – until he felt a hand pull his head up by his hair – followed by a searing pain as Gil entered him without any preparation. Greg let out an inarticulate scream and tried to fight back against the handcuffs. All was quickly forgotten when he felt Gil pull back and then slam into his prostate.

"Yes!" Greg called, forgetting the rules – Gil had forgotten them as well. A hand reached around and grabbed his cock to start jacking him off.

Locked between the cock in his ass and the hand around his own member, Greg came forcefully against the sheets in front of him. He felt his knees go weak and give out on him. Gil grabbed the slim hips and continued to thrust until his own orgasm overcame him and he fell on top of Greg. Minutes passed before anything was said.

"Griss?"

"Yeah?"

"I'm still tied up."

Gil undid the cuffs and took Greg onto his chest.

"I'm sorry if I hurt you."

"I never said stop, did I?"

"No."

"Actually I think mind-blowing sex was just what I needed after today. I was sure I'd be sleeping alone."

"Sorry you had to be punished," Gil said sleepily.

"Are you serious. I may go set the living room on fire just so you can punish me later!"
