Robbie shrugged. "Sure you can keep me company. In fact I'd welcome it after the fiasco on the grass."
He took my hand and we walked to his room. I sat on the bed as he stripped off down to his briefs, never taking my eyes off him. I wanted to determine the state of his cock and when he turned around I wasn't disappointed. It was making a huge bulge in the front of his bright red underpants and my pussy gave another little shudder.
He climbed into bed and I sat facing him with my legs folded in front of me. I knew I was giving him a great view of my pussy but so what? It was a fair repayment for him allowing me to hold his cock for a little while.
We talked about inconsequential things at first. What my day at work had been like (I didn't tell him about Dave pressing his cock against my back) and how his day had gone. Where he had been that evening.
How he met the girl and all that kind of stuff. All the time we were talking I could see his eyes moving over my body. He was especially fascinated by my tits for some reason but every now and then his eyes would stray down to look at my pussy. I was really enjoying myself. Not only just sitting around bullshitting with Robbie but showing myself to him as well made it all the more fun, to say nothing of exciting. I don't know why I suddenly had this urge to expose myself although, in reality, I suppose it was due to the fact that I wanted to see his cock all big and hard and I hoped my body, slightly imperfect though it is, would do the trick.
Talking about him picking up the girl started the conversation on a more interesting track and opened the way for me to ask questions like: "What's it like when a girl sucks your cock?" and "How many times have you made love to a girl?" and "Have you ever put your tongue inside a girl's pussy?"
Robbie answered all my questions although the look on his face was priceless at times. I guess he simply couldn't believe he was having this kind of late night chat with his little sister.
It was time for the biggie. The sixty-four thousand dollar job. I took a deep breath and plunged right in.
"Robbie," I said as calmly as I could despite the fact that my heart was going a hundred miles an hour and my pussy was beginning to quiver alarmingly. "Is your cock hard right now?"
He pursed his lips and stared at me, his face so serious that I felt sure he was going to spank my ass and throw me out. Slowly his lips turned up just the tiniest amount and his eyes began to crinkle. "You get right to the point, don't you?"
I smiled back at him and tilted my head to one side. "Well? Is it?"
"As a matter of fact it is. And my underpants are practically cutting me in half."
"So take them off, silly," I said.
He wriggled around under the covers and a pair of bright red briefs flew across the room. He sank back on his pillow with a deep sigh of relief.
"Better?"
"Oh yes," he gasped.
"May I see? I've never seen a hard one before except in X-rated movies."
There followed the loudest silence I have ever heard. We stared at each other for what seemed like hours. I was so excited and the fact that his cock was hard meant that he too was excited. And I wanted to see his cock so badly. It was there just a few inches away from me, covered by the bedclothes, all hard and stiff. I had to see it. I simply had to.
"I thought you saw it when I was out on the lawn," he said and I knew then that I would see it. He was just teasing me, leading me on a little.
"But you were so far away and the light was pretty dim. I want to get a close-up. Please."
He relaxed against the pillow and placed his hands behind his head. He never said a word. He didn't have to. His passive attitude told me to help myself and that was exactly what I wanted to do.
My hands trembled slightly as I reached for the edge of the covers. In fact my whole body was shaking and my pussy was going berserk. The insides of my legs were damp from the juices that had squeezed out of it.
I gripped the covers and slowly drew them down over his flat belly and there it was. His knob appeared all swollen and a pretty purpliepink color, then the rest of his cock so white and smooth with thick purple veins running along its length, a tuft of dark wiry hair then his balls. They looked huge and heavy as they laid against the tops of his legs.
I stared down at him, hardly able to believe my eyes. It was the most beautiful, desirable thing I had ever seen in my whole life. A perfect cock if ever there was one. I had to touch it and I placed the tip of my finger against the translucent skin and slowly traced the line of one of the veins all the way to the ridge at the bottom edge of his thick knob. It twitched under my gentle touch and I slowly lifted it away from Robbie's body and placed my hand around it. It was so thick that I could hardly circle it so I took it in both hands and began to stroke it real slow.
Robbie opened his eyes and looked up at me with a tender smile on his face. "You realize that this is extremely wicked and sinful, don't you?"
I nodded and smiled at him. "So we'll both go to hell. You were heading that way anyway and I'd hate for you to be all alone down there."
"I know I was," he said. "But I thought you were still the sweet little virgin sister."
I tightened my grip on his sweet cock. "I'm still the sweet little virgin sister and you'll be proud to know that yours is the very first cock I have held in my entire life. Hard or soft."
"I'm flattered."
"So you should be." I gazed into his eyes. "It's beautiful, Rob. I never dreamed that holding a cock in my hands could be this wonderful."
"You are quite a revelation tonight, little sister. I hadn't noticed quite how beautiful a body you had either."
I felt the color run to my cheeks and my pussy jumped again. "What this flabby old bod of mine? You're kidding."
"No I'm not. You have a lovely body. I never knew your breasts were so large. I guess I just didn't notice, what with you being my sister and all "
"Would you like to see more?" I asked.
He nodded and I let go of his cock reluctantly and pulled my nightie over my head. It joined his red briefs on the floor. Now we were both naked. Now what? I took hold of his cock again and carried on with the slow stroking while Rob's eyes did a slow, lazy tour of my body. I wanted him to touch me and yet I wanted to retain some control over the situation. While I sat where I was out of his reach and all my energies could stay on playing with his cock. That was what I wanted, or at least thought I did. Now I wasn't so sure. My pussy was going crazy, begging for attention but I had both hands occupied and I wasn't about to let go of what I'd got just to satisfy the ache between my legs.
Rob reached out and took hold of my arm. "Come and lie next to me," he said in a strange, tense voice.
I hesitated, unsure of what might happen and yet wanting anything and everything to happen. He tugged gently at my arm and I gave in quietly. I rested my head on the pillow next to his and his arm wrapped around my shoulders, drawing my face close to his. I could feel his warm breath on my cheek and his lips so close to mine. I wanted to kiss him so badly and when his lips finally touched mine it was like a damn had overflowed. All my pent-up passions and frustrations were let loose as I forced my tongue past his open lips and into his mouth.
I pumped his cock harder and his hands were all over me; touching my breasts, stroking my ass, pressing me tightly against him until I could hardly breathe. I broke away gasping for air. Our lips met again and he eased me over onto my back, his hands opening my legs, his fingers touching the lips of my pussy and spreading the soaking wet folds of skin until he found my clit.
The moment he touched it I was gone. I writhed around on his bed, crying out and moaning as he rubbed and teased me. I don't know how many times I came but it got to the point where it seemed like one long continuous orgasm was ripping through my body. I still had his cock in my fist and my lips were all over his face. He pushed a finger as far inside my pussy as it would go and I came again. I wanted him to shove his fingers all the way inside me and fill my pussy but my rotten, stinking hymen wouldn't let him. But just having his fingers a little way inside me felt fantastic.
