My Sister's Boyfriend 02

Really, it was difficult to think of anything else. That afternoon had opened my eyes, mind and body to a wonderfully thrilling and erotic new world. An unexpected new, sexual world. One that I quickly felt so drawn to, and drawn to him.

That afternoon, my sister had left me alone with her boyfriend. I doubt that she had any idea what had happened. I doubt she ever thought that anything would happen. Something did though, and I quickly and truly loved it!

Late at night, the memories and desires of that afternoon would come flooding in. I imagined that I could still see him, still feel him, and his cock. Still taste it and smell it on me, his cum. I'd get so aroused. All I could think of was being alone with him again. All I could think of was his big, black cock.

Several afternoons a week, my sister and her boyfriend would disappear into her bedroom. I could hear them through the door. Sensual sounds, sounds of sucking and sex. I found myself so jealous of my sister. getting that black dick. I wanted more. I wanted to watch. Before they got home one day, I went into her room and moved the blinds that covered her window, making it so I could see in from the outside.

I watched him undress. Seeing his big, beautiful, hanging dick again made me so quickly rock hard! Made me drool and my lips tremble, desperate to feel it on them again. He layed back and she moved between his legs. I knew that thrill, that anticipation!

That first afternoon, it had started with him convincing me to let him suck my cock. I was nervous, but horny and quickly gave into his charm Funny how that, my own pleasure, had now taken such a back seat to getting to pleasure him!

His amazing, dark cock grew as she licked it. He touched her face, he guided it into her mouth. I so wanted to be her! I watched as my sister stepped out of her clothes, then got back onto the bed. She moved to her knees, then onto her hands, also. There was something oddly sexual and arousing about seeing her like that. Nude and so sensual. I had hardly noticed that my hand had moved to my crotch and was rubbing my hard cock, through my pants!

He moved behind her, I watched as his cock slowly began to disappear inside her. The look on her face! Just pure ecstasy! Even through the window I could hear the slapping sounds as he pounded into her, over and over. Gosh, they looked amazing! I took my cock out. It felt so good to stroke it, in time with his thrusts. Her moans were infectious, his grunts primal and achingly erotic. Could he fuck me like that? Embarrassingly, I came so quickly, shooting my cum all over the wall, outside her window.

When I heard my sister's car leave, I went back inside. To my surprise, she had left him behind! Had he asked her to? I knew that I blushed, I could feel it. I felt flushed. Surely he could see it, too. I had just watched him fuck her. I had been dreaming about his cock. It had to be so obvious. My thoughts, my desire, they had to be so obvious!

I couldn't think straight. I could barely speak. All I could do was stand there, hoping that he would take that huge, black cock out, again. I just stared at the floor, searching for the nerve to ask. Overwhelmed, so horny and seemingly so desperate. I just had to ask. Sheepishly, I asked if I could suck his cock.

He simply said, "You read my mind!" I was already moving to my knees. My body reacted to him undoing his fly before my mind even had time to process it. His glazed cock hung before me. My sister's cum had dried on it, making his cock look almost frosted. I didn't even hesitate. I took his amazing, big cock's head between my lips and eagerly sucked it. I took more and tasted it. It made my head spin, sweet and cock tingling. I tasted my sister's pussy on it. More erotic and titillating than I ever would of thought!

"She'll be back soon," he said softly. The pleasure in his voice, in his breathing. I found it so exciting to be able to affect him like that! He pulled his cock away and held it up. His hand on the back of my head, he guided my mouth towards his balls. He didn't have to, though. I wanted it, more than he knew, more than anything. I couldn't wait to suck them! Still, I liked it. I seemed to like him taking charge, like that. They were hanging, each one well defined and still damp. His sweat? Her juice? Both? I sucked them and moaned without thinking. I felt so intoxicated!

I felt him guiding me to my feet, saying under his breath, "We got to hurry, man!"

I had to steady myself as he pulled down on my pants. His strength, my dizzying arousal. I had no doubt that I could cum again and let him give into his own need and passion. Gosh, his warm, wet mouth felt so good! I quickly fed him my cum. Shaking, unable to catch my breath. He quickly stood and pushed his cum coated tongue into my mouth. My knees seemed to buckle. My head just continued to swim. I liked it more than I ever could of expected. His tongue, like his cock, had the ability to just make me melt!

He began to stroke his big, gorgeous cock. I so eagerly returned to my knees, ready to please him, but he held my head, his fingers through my hair. My mouth opened, instinctively... ready. I could sense his urgency. Did he know my sister was returning? His cum dripped down on me, like a euphoric rain. I felt it on my face, in my mouth, making me so shamefully moan. When he let go of my hair I sucked the last drops out from his cock's tip. I just wanted to thank him for it.

We both heard the front door open! He turned and I sprang to my feet. Zipping up, wiping the cum from my face. Would she catch us? What would she say. We both turned back to face her, just as she entered the room. We were both almost breathless, flushed, even guilty looking. To my surprise, she didn't say a word. Did she already suspect? Did she already know?

He said, "Hey babe," and kissed her on the lips. All I could think was that she might of tasted my cum on his lips. Afterall, I had tasted hers and there was just something so kinky and erotic about it!

It started to feel like a game. A playful, kinky game. When she didn't question what went on when she was away, it felt fun to push the boundaries, right under her nose. It was a turn on. It was so arousing, like getting away with something. When she turned her back, I'd brush my hand across his crotch. When she wasn't looking, I'd back into him and rub my ass on his cock.

When she turned and spoke, my jaw dropped. My heart stopped. She turned, a sly smile on her face and said, "Why don't you two just fuck, already!"

My mind nervously raced! Did she know? Had she seen? Did he tell her? Where would it go from there? Where could it go from there? I was so shocked and scared, so why was my cock getting hard, again?

The end...?
