Chapter 1

Scott was listening to the sound track of the soft porn video on his computer. Because of the headphones, he didn't hear his younger sister Melissa walk into his bedroom. He might have sensed her arrival if he hadn't been masturbating so furiously. He was wearing just pajama trousers, with his cock sticking out of the fly. He was beating it pretty hard now, as the black man on the screen pounded his monster cock into the cute white girl on the bed under him.

So his younger sister was able to walk close up behind him without him noticing her. She watched the video for a few minutes, by her standards a very boring one-on-one sex action, the only interesting feature being that the man was black, and hugely endowed. The girl looked as though she was grunting with each thrust, but Melissa couldn't hear the sound track. Melissa was wearing just a towel wrapped around her naked body, having emerged from the shower moments before. As she walked back toward her bedroom, she had noticed that Scott's door wasn't fully closed, and had gently pressed it, and it had swung open. She was amused to see the rapid motion of Scott's arm as he pumped his pork. She decided she wanted to see how big her brother's dick was!

After a few minutes standing at the door, she stepped closer, expecting him to notice her any moment, but she realized the earphones prevented him from hearing her, and he was far too engrossed in the vid he was watching to notice her behind his back. She had the sense to keep to one side so her reflection didn't appear in the screen Scott was focused on, until she was close enough to see it was tilted quite well back so she wouldn't be visible if she kept herself low down.

Very carefully she reached forward and suddenly tugged the headphone from Scott's right ear! Scott jerked, twisted round in his swivel seat, and gasped to see her standing there, grinning at him. She hissed at him to keep still. Both his hands were now covering his crotch, and the look on his face was a treat. She put her hands on his chair and turned him back toward the screen. "Shhh, hon, just watch the vid. Let me watch it too, I want to see it."

Scott looked back at the screen, and Melissa came very close behind him, her mouth close to his ear, and she whispered, "Scott, it's okay, I really do want to see this. The guy is magnificent. But let me listen to the sound track."

She reached over his shoulder for the dangling earphone and slipped it into her own ear then rested her chin on Scott's shoulder, watching the action on the screen. She started moaning in tune with the porn girl's moans, just to excite her brother. "Oh yes, give it to me, you beautiful black fucker," she panted, and Scott could hardly believe this was happening.

Scott was of course shocked and stunned, but also hugely relieved that Melissa was sympathetic and not critical. He had always known that Melissa was more advanced sexually than he was, hell everybody he knew seemed to be. But he had never discussed sex in any form with his sister, nor even with his mother except when she insisted on discussing things with him. He was just too shy, and increasingly ashamed of his lack of experience in that field.

And now suddenly Mel was in his bedroom watching porn with him! And, from that brief glimpse he had of her before she made him turn back to the screen, he knew she was wearing a towel, and just possibly had nothing on under it! That thought was far more exciting than what was happening on the screen in front of him.

The porn girl was now sitting up, the man standing in front of her, pushing his cock into her mouth. As she started sucking the black man's cock, her big silicon filled boobs were sticking out. "Jeez, I wish I had tits like those," Mel sighed. Scott should have said something nice about his sister's quite nice boobs, but he just didn't know how to compliment girls. Instead he sat there imagining that Mel suddenly did have those huge melons he was watching on the screen, and he imagined Mel pressing them against his back!

His sister twisted her head forward so she was looking down into his lap. "What happened to your dick, bro? It was looking fine when I came in."

Scott glanced down at the shriveled wreck of his erection. He wondered if it would ever recover! Then, as he watched, Mel's hand came around him and delved down into his pjs! "Oh God," he groaned, as her experienced fingers flexed his totally inexperienced dick. Inevitably his organ responded immediately, and in seconds was in full erection.

"You've actually got a great dick, Scotty, I'm impressed." She was holding the shaft now, and Scott shivered. "Why don't you have a girlfriend to play with it for you?"

Scott grunted something inaudible, and she stopped moving her hand. "What was that, bro? You don't have a girlfriend, do you?"

"No." She moved her hand again.

"Have you ever had a girl stroke your cock? Before me?" When he didn't reply she stopped moving her hand.

After a breathless minute, he moaned, "Please sis, don't stop."

Instead she took her hand away. "No, you do it. Show me how you stroke it. Go on, you were stroking it just now when I came in, stroke it again."

Reluctantly Scott put his hand back on his cock and started stroking it. Mel turned her head slightly and kissed his cheek, nibbled his ear, the way her latest boyfriend Troy liked her to do it. "That's nice. Keep doing that. Did you like me touching it just now?"
