The Sister, Part Sixteen
Part Sixteen
Natalie didn’t seem like the type to have a sister complex.
She and Jessica were night and day when it came to personalities. And, based on Natalie smirky arrogance, this was more about messing with me than it was about anything else. Constantly reminding me that I had a girlfriend who was dangerously nearby, and exactly who it was that I was currently fucking. Natalie stared me down, waiting to hear the words she had demanded.
In a way, it was true. She was better, at least from a sexual standpoint. Jessica had never gone down on me, as she wasn’t super into that, and Natalie had somehow figured out my body in a matter of minutes compared to the time it had taken Jessica to learn the nuances. Even now, Natalie and I were in a position far less vanilla than my first time with her sister had been. What else did the tempting girl have to offer, if this experience was what she started with? And why the fuck was I thinking along those lines, when I was so recently prioritizing resistance?
Gently rocking her hips, just enough to keep me hard down there while still teasing anything more, she continued her intense downward gaze. “Don’t you dare take your eyes off of me. Not for a second,” she murmured.
Again, I nodded. Throat suddenly feeling very dry, and wanting nothing more than to push this further than merely existing inside her tight, petite body, I reflexively thrusted forward in response to the movement of her hips.
She literally went the opposite way. Not letting me start anything, yet keeping me on the hook every second of the way. “I’m better than Jessica?” she smirked, “Say it.”
“Fuck you,” I muttered.
“Only after you say it,” she replied, in a lilting tone.
Fucking brat. But I did as I was told. Giving her bare backside a firm squeeze first and using my grip to pull her forward so it would be more difficult for her to tease me in a similar manner as before, I echoed, “You’re better than Jessica.”
Going along with my gesture, she rocked forward, only giving me the satisfaction after I said what she wanted. Unlike before, however, she slowly shifted back and then forward again. Actually letting me fuck her, rather than simply allowing me to penetrate her. “You want me more?” she asked, in a breathy exhale. Eyes still trained on mine, silently demanding that I reciprocate like she recently told me to.
Nodding first, and thrusting in response to her movements, I said, “I want you more.”
“More than who?” Rather than backing off, she slightly increased her speed. Her hand that had been gripping and guiding me down there before had come up to mirror her other hand, and she used both of them to sink her fingers into my shoulders as she held me more tightly than before. Taking a shaky inhale, her eyes fluttered but never truly closed. She let out a quiet moan, looking at me with the most sultry yet expectant expression.
Unable to think clearly any more, I matched her pace and said exactly what she wanted. “More than-” Cut off my a quiet grunt of my own as Natalie and I fell into a rhythm that was building slowly yet quickly, I quietly said the rest, “-your sister.” While mentioning the relationship hadn’t been a requirement, I was at the point where I would say anything to keep her from edging me further. Or maybe, deep down, I was caught up in the taboo of the whole thing and slightly leaning into it now that we were long past the point of no return. And yet, she backed off nonetheless, slowing down enough that it was noticeable. Falling for it in my desperation, I blurted out the whole thing. “I want you more than your sister!”
Rather than smirking again, she pouted. “But she’s your girlfriend. I’m just an innocent little high schooler. Maybe we shouldn’t . . .”
FUCK. HER.
After all the times I tried to protest with ‘we shouldn’t,’ she was throwing the words back into my face when it was clear that I didn’t plan on stopping now that we had made it this far. She was fully naked, wrapped around me, and I didn’t care that she was eighteen or Natalie’s sister. This was going to happen. End of story. If only to satiate her one last time, I said with a glare, “I want you, Natalie. More than Jessica. More than anyone.”
“But I’m your girlfriend’s-
“Shut the fuck up.” Thrusting into her, hearing the last two words in my head despite how I had cut her off before she could say them, I stared into her eyes and told her with my body to just get on with it. We had been through the taboo enough with her constant teasing reminders. Enough was enough.
“Good boy,” she whispered. Even though I had been the one to just assert myself, she instantly and effortlessly reframed things like she was still every bit in control. And it fucking worked. That same little phrase instantly caused me to harden more than before; I slightly pulsed inside her as she matched my more aggressive movements, but I was better than that. After all this, I was going to make things last.
Unfortunately, the universe had other plans.
Just as I was preparing myself to truly and fully fuck Natalie, Jessica’s voice cut through the clouds of lust that had me wrapped around her sister’s finger. “Hey, babe? You still upstairs?”
‘Shit. SHIT.’
Of course she was coming to find me. It’s not like taking the cover off a boat took very long; she had probably applied sunscreen afterwards, but then what? I had totally lost track of time. Natalie and I could have been in here for two minutes or a half hour for all I knew, and Jessica wasn’t just going to stand around waiting for us. There was no way she would suspect something like this, but still. I was fucking dead if she found us in the same room together and caught a whiff–literally or figuratively–of what we had been doing.
“I’m her little sister,” Natalie grinned.
And then she did the complete opposite of teasing. With no warning, she started rocking her hips against mine, perfectly flexing her muscles to coax out any firmness I had momentarily lost from hearing my girlfriend’s voice calling through the house.
I was completely helpless against her sudden advances. Not even Jessica’s voice had been enough to fully bring me back to reality, nor had the enormous risk of her discovering us if we didn’t hurry. Using my grip on her bare ass to make sure she stayed at a good angle, I began thrusting into Natalie, desperately trying to keep up with her wicked pace. There was no edging or build-up involved. She knew just what to do to get me off as quickly as possible.
Within seconds, I was releasing inside of her. Natalie let out a breathy moan, biting her lip right away to keep things quiet as I continued to pump into her with no hesitation now that I had started. She bounced up and down on me in all the right ways, making sure to take every last bit of me before slowing down.
We never once broke eye contact throughout the climactic experience, and she sighed out one more soft moan before smirking. “Told you,” she said.
