“So, you like this, huh?” She said, starting to pull her shirt up an inch more. I nodded, concentrating my eyes where I could just barely start to see the skin of her breasts. She raised her shirt a little more and the curve of her breasts came into view. My hand was shaking as I started to rub my dick through my boxers.
“Sorry, I’m not giving you a good enough view.” She said, quietly, and slipped the straps of her shirt over her shoulders with her other hand. Her shirt flopped down, uncovering a lot of her cleavage. She continued moving around, swaying her hips and arching her back. With the hand holding the bottom edge of her shirt between her breasts, she hooked her fingers on the top edge and pulled it together in her hand, drawing the fabric tight across her breasts. Then with her free hand, she took hold of the edge of her shorts and started to slide the front down. More and more skin came into view until I could just see a hint of hair. I gasped, now stroking my penis fully as I looked at my sister’s body.
She gave me an alluring look and smile, swiveling her hips. She rubbed her hand on her chest around in small circles, pressing her breasts from side to side. The hand holding her shorts moved around as well, sometimes showing less skin, sometimes showing more. I grabbed my dick more firmly now, even to the point where I had my fingers wrapped around it over my boxers. At the moment, I didn’t care so much that she could see so much of me. I watched as more of her light pubic hair was revealed and responded by stroking myself even more methodically, focusing on the tip of my penis. In return the hand on her chest happened to tug one edge of her shirt up a little further and more of the underside of one breast came into view. I felt my precum leak out and begin to wet my boxers and I rubbed the slick fabric around the head of my dick.
Then she slid a finger right into her shorts, right in the front, right where her hair was, and it went down pretty far. She wouldn’t look up at me. I pumped my dick as I stared at her hand and watched it go even further down, and she started to move it. The hand she held her shirt continued to move too, rubbing the center of her chest tightly. Her body seemed to be shining and I realized it was sweat. Her hand kept moving, her shorts, advertising her movements.
Sara finally looked back at me, her face rosy, and our eyes met. I didn’t mean to ejaculate right then, but I did and her eyes remained on mine the entire time I shot my load. As the last shot was coming out, her face grimaced and she grunted. I was still rubbing my dick as she worked her hand and we could both hear the sounds of wet flesh coming from each side of the room. Our eyes stayed locked until she gasped hard, licked her lips and closed her eyes.
Sara let go of her shirt and pulled her hand out of her shorts. Her shirt almost slipped down, but she caught it and slipped her straps back up. She rested for a minute on her bed. Finally we looked at each other and smiled. The room was quiet, but it felt intimate. It smelled intimate, too.
“Sara,” I began, then just shook my head and grinned at her. She smiled and looked down bashfully.
Not wishing to sit there in my own cum anymore, I started to get up. She stopped me just as I stood and said, “I really like seeing that I caused all that.” and gestured at my soaked boxers. She grinned at me and I shook my head and chuckled. I grabbed all my stuff and looked back at her and she looked at me. It felt weird, but I felt strange leaving her. I could tell by her look that she didn’t really want me to go.
“Um…” I stammered, “Would you mind if I came back after I get changed and we can just sit and chat?” She grinned happily and agreed. I left her room and returned a few minutes later. We just sat there and talked quietly for a while. We didn’t really talk about anything in particular; it just seemed that we both just needed to be with each other for a little while longer. I left her room a little after midnight.
