Chapter 9
I stood up rapidly, wanting to get undressed before she changed her mind again, and she pulled herself into a lounging position instead of lying on her back. I flung my shirt aside and it landed briefly on her dresser before sliding to the floor. My pants and boxers I just dropped directly on her carpet, then half-walked, half-hopped to the edge of the bed.
Krista scooted her butt on the covers to meet me, legs bent and out of the way. I guided my cock to her pussy and she used her hands to spread it open. I didn't think much about what I was about to do, other than the sheer want of it. I'd been a virgin 17 years… too long. No longer.
The head of my cock touched the edge of her hole, and she shivered while my dick twitched and let out a little precum. I didn't want to wait any more, so I pushed in, slowly but without stopping. Before long, I was all the way inside her. I looked down at the union between us, and then at my sister's face, suddenly worried that I might be hurting her, or worse, that she'd changed her mind at the last minute. She stared back at me and smiled, dispelling my fears, and moved her hips back and forth as though to give me a hint about what to do next.
I took that hint and pumped in and out, at first just a slow sawing motion nearly all the way out and then back in, but very soon I'd moved up to quick thrusts as I supported my weight with my hands on her bed just beside her shoulders. It certainly beat my hand, was superior even to her mouth, but that might have just been that I knew I was not only fucking but fucking my own sister. The little grimaces she made as I slammed into her were beautiful, at least once I got over the fear that they were from pain. If it was from pain she wouldn't be rocking back against me, she wouldn't be telling me "more" in a breathless voice.
We changed positions, once, after I slipped out of her with an over-enthusiastic pullback. After an initial off-centered stab to get back in, Krista drew her legs back and pulled back on the bed. "What?" I asked, the old fears returning. "Something wrong?"
"No, I wanna try another way. Sit down."
I fell to the bed beside her, and we shifted together as she crawled over me to straddle near my waist. With one hand she reached behind herself and grabbed my dick, centered it, then fell back, sinking all the way down. Once we were fully coupled again, she started to move, even more energetically than I had. My hands settled on her thighs at first, but then after a while I rose up and squeezed her tits for a while. That wasn't enough for long and I took one of her stiff nipples in my mouth and began sucking on it as she moaned.
As much fun as it was, I decided I couldn't let her do all the work so I pistoned my hips up and down. If she wanted to ride me, I wanted it to be a ride to remember. I even rubbed the top of her pussy a little with my thumb for a bit more stimulation. I heard a noise, but disregarded it, figuring that the force of our movements had bumped the bed against her night table and knocked something over. It wasn't important.
What we were doing was almost all-consuming. It was a wonder I hadn't cum… I guess it was my subconscious at work, I was so concerned that I leave a good impression that I wasn't relaxed enough to actually climax. That wouldn't protect me for long, though. Mostly, while we were in this position, Krista had kept her head pointing upwards, looking at the ceiling instead of at me directly. That changed suddenly. For no reason I could figure out, she slowed the pace of her bouncing and looked me in the eyes, drew closer. Our mouths touched, a gap formed, and our tongues met in the middle, played together, while we rocked together.
The kiss broke, resumed, broke again, resumed again, and then the next time she broke it Krista began riding up and down again like a woman possessed. She closed her eyes, and was whispering softly. "Yeah, fuck me, show me you love me too." I guessed she was deep into fantasy mode, now, pretending I was some guy she fancied. I didn't answer in words, not wanting to break the spell, but struggled to keep up the motion. The bed began to creak beneath us, like it was unable to withstand the force.
"Yeah, that's it, fuck me, fuck me, give me all you've got, Bobby."
It took a little while to sink in that she'd used my name. Did that mean the guy she was imagining was me? Or did she just slip out of the fantasy a moment? I didn't know, but I preferred the first idea. So, when she next spoke, I decided to answer.
She asked, "Do you like fucking me Bobby?"
"Yeah, I love fucking you, Krista. I love you." My face curled in an involuntary wince, worried it would make her freak out, but it didn't, she kept moving and buried her face in my neck. She kissed me up and down. It was intoxicating, freeing. I began to lose myself, my inhibitions, my fears about my performance, everything, determined only to give her all I had.
"Mmm... me too. You going to cum?"
"Pretty soon."
"Go on, cum inside me." I almost did, then, but I had a little more fight in me so I gave it all I had, putting all my energy into the finish as Krista made sharp cries of pleasure. She was close, and if there was one thing I wanted more than to empty my load inside of her, it was to make her cum first. Our combined movements rattled the bed and every so often another creak would ring out.
That was where everything turned on its head. Wouldn't you know it, the one time I'm not neurotically paranoid about the littlest things, obsessing about all the possible ways things could go wrong, is the time it bites me in the ass. If I hadn't been so wrapped up in the passion of the moment, I might have considered that Mom might not spend as much time shopping if she was only buying fresh fruits, vegetables and meat, instead of pre-made meals, that she might have gone to a nearby vegetable store with a butcher right beside it instead of driving all the way to the grocery store. If it didn't feel so damn good to have my sister bouncing up and down on my dick, I might not have dismissed that noise as 'probably nothing', I might not have been on the verge of cumming and unable to stop when I finally realized that some of the creaks weren't from the bed, but were from the stairs.
"Oh my god," my Mom's voice rang out a second after the door swung open, but it was too late. I had just squirted a load in my sister's pussy as she cried out. Both of us stared, in shock, at the door. It was impossible to hide what we'd been doing. We were all frozen that way, the three of us, while my Dad started up the stairs, drawn by my mother's shout.
As he looked at the situation, his eyes widened, and he even drew back, reeling a little. Not much, just a fraction of an inch. It was still probably the most surprised I'd ever seen him. He was frozen too, unsure what to say. Finally, as my cum started to leak out of my sister's pussy, he had his answer ready. "Well, Lorraine, you said you wanted the kids to be closer. Well done. Mission accomplished."
