9
Saturday morning brought conflicting, painful thoughts.
I lay in bed, well past the moment of waking up, my mind racing with lewd, heartbreaking images, and desperate "what if?"s.
I thought about what I had left last night - If I had just had a better handle on my own feelings, I could have stopped it, but instead my mind was full of images of Tara passionately running her mouth up and down Bud Pepper's big cock before taking him deep inside her body. Images of him on top of her, between her legs, thrusting hard into her, a look of ecstasy on her face. Of her riding him, grinding on him, eyes closed in pleasure, his hands on her perfect tits. Squeezing them. And then that moment. That beautiful, erotic, intimate moment when he pushes his full length deep into her, his balls tighten, he groans an animalistic groan, and gives her all of his hot joy.
It was the thought of him cumming in her that irked me the most, and I wasn't even sure why.
Then I thought about what could have been if I had said something different. Maybe it would be me she held tight to her body, having that connection. Maybe it would have been my sperm cradled deep inside her as our passions cooled down. Or maybe we would have just talked through the night, and worked our way through the confusing realities of being two, 18 year old friends who were horny for each other but just couldn't say it.
Maybe.
The rest of the day was a confusing blur. My run brought me no relief, and neither did the hot shower afterward. I couldn't even jerk off to clear my head, as I was too scattered to manage an erection, even with those lewd images in my head.
The day slipped by quickly, and then it was time for me to pick up Steph from work.
I needed answers. I was angry, angry about what had happened last week, what happened at the prom, angry about how it had gotten me all mixed up and ruined my relationship with Tara, so when I texted her I had arrived, and she once again texted "come inside," I responded with a curt "no."
After a short while, Steph responded with a simple "ok," and came out to the car a few moments later.
We drove in silence, but Steph spent the whole ride watching me. I could feel her eyes on me, but I never met them. I felt the frustration of the situation coiling up behind my eyes, but she just sat there, cool as a cucumber.
I rolled into a park in the same darkened area by our building that I had parked the last time. She didn't move, and I didn't move. She just watched me. She knew I had something on my mind, and was going to stay still until I said my peace.
Finally the silence got too much, and I cracked.
"Steph, what the fuck is going on?" I blurted out.
"What do you mean?" she offered back, dipped in hot sarcasm.
"What's going on? What do you want from me? After what happened at the prom, and last week, I don't know what you want from me, and it's driving me nuts." I complained, balking on the chance to mention Tara. I definitely didn't go all the way with it.
"I thought we covered this last week?" Steph responded with the same, dry, flat tone, "What did you tell me you wanted?"
I thought back to last week, when she had me by the balls just before she had me by the mouth. "...More." I said weakly.
"And has that changed?" she inquired, raising an eyebrow.
I racked my brain, and my feelings, and as much as I was torn up and turned over about Tara, and annoyed at being some sort of fuck toy for Steph, there was one clear truth that stil pushed it's way to the top: "No, it hasn't."
A smile formed on Steph's lips, and she slid across the bench seat of my car, tucking herself tight up against me. Her hand flitted across my thigh.
"Well then I don't see what the problem is..." she said as her hand snaked up to my belt. "I'm going to give you more," She said as unbuckled my pants and dropped my zipper, "in fact I'm going to give you more than you could possibly handle...and you're going to thank me for it."
Her hand ran over my balls, squeezing them gently, eliciting a low moan from deep in my chest. She parted the flaps on my underwear, and with a delicate precision, Steph pulled my hard cock through the hole in my briefs, freeing it to the cool night air.
"There's just one thing you've got to remember, Timmy," She languidly poured into my ear. Her hand gripped my cock firmly, and slowly started to stroke. "And that's that THIS..." she emphasized, giving my cock a hard, signifying squeeze, "...belongs to ME."
I felt her lips at my ear, and heard the erotic squeak of her tongue moistening them. Then, she pulled away from my ear, and with a slow, deliberate glide, she began to lower her head toward my straining cock.
This wasn't the quick, dispassionate handjob from the previous week, this was something different. She was going to rock my world. I held my breath, waiting desperately for her lips to touch my tip and complete the circuit between us. Lower, and lower, her head dipped. Her lips were so close - the same lips I had felt at the prom, the same lips that had coaxed my cum out into her mouth.
Then, with mere inches left, she stopped short, and let out a sudden, panicked "SHIT," and recoiled off me completely, like a slingshot. Before I could even react to what was happening, she hastily shoved me back into my pants, gathered her things, and launched out of the car.
Following her with my eyes, frantically looking for some reason as to why she stopped so suddenly, I quickly got my answer: Standing near the walkway to our building, not 10 feet from my car, was Alex, my step-sister, and Steph's best friend.
I watched them from the car as they hugged and laughed. Steph had instantly changed into a different person. Gone was the sultry domme who had just asserted ownership over my hard cock, replaced with the Steph I remembered from my youth. The Steph who was no more than the teenage girl who lived upstairs.
Alex pointed to the car, and Steph just gave a dismissive eye roll. She seemed a little frantic in her mannerisms, trying to move Alex's attention elsewhere. Something was strange about it. I tucked my deflating cock back into my pants, and decided to go investigate.
"Hey Alex!" I called out as I approached the duo standing by the front stairs. "What're you doing home?"
"No class on Monday so I figured I'd make a long weekend of it at home." She responded. Her head darted around the grounds of our building, puzzled. "Hey, where's mom?"
"Not sure," I replied, "she's probably out with BRIAN." the name dripped off my lips in an exaggerated, dismissive tone.
"Brian?" Alex responded
"Yeah--hate to break it to you, but I think Kelly's got a boyfriend!"
"Wow, really?" Alex's eyes widened and her brow ticked upward. "That's...unexpected. What's his deal?"
"Not sure," I shrugged, "he seems to be a decent guy--he's a friend of Sandy and Don's." Friend, of course, was putting it extremely lightly.
"Oh, no way! Steph, do you know anything about him?" Alex lightly exclaimed.
"Nah, I've met him once or twice, but never really talked to him before." She said, brushing a strand of golden hair off her face. My eyes drifted down to her chest. I could see the faint shadows of her nipples through her shirt. She crossed her arms, trying desperately to hide the remnants of the arousal fired up minutes ago in my car.
"Yeah, you know Steph and I didn't really talk about it at all..." I began, staring her right in the eyes, "...when we went to my prom together last week." Her stare was like ice.
"Whoa, WHAT?" Alex exclaimed with a laugh, "You went to PROM...with TIM?" I could see Steph shift nervously.
"Yeah, she was my prom date," I said with a smirk, my eyes never leaving Steph's, "until she ditched me halfway through the night!" Steph was frozen now. She was embarrassed that she went to a high school prom with her best friend's younger step brother, and I was happy to turn the screw, but not even I was cruel enough to tell Alex EVERYTHING that happened that night.
"Wow, for real?" Alex asked again with another chuckle.
"It was just a fuckin' goof," Steph proclaimed wildly, "and I ditched because Timmy was being a total PERV!" She was deflecting now, and not very convincingly.
"Oh yeah? Is that true, Timmy? Were you being a perv?" Alex laughed in response.
"Yeah, I whipped out my dick and started jerking off right in front of her!" I exclaimed with a thick coating of overdramatic sarcasm. Of course I actually WAS telling the truth...but only Steph and I knew it.
I smiled as I watched Steph sweat. "Ew, gross, Tim," She replied, her face contorting into a disgusted grimace. "Come on, Alex, let's go." Alex led the way, and Steph shot me an ice cold glare as she followed. It did absolutely nothing to wipe the shit-eating grin off my face.
It was a glare that was a front of anger, but betrayed something else beneath it. I couldn't quite put my finger on it, but as I walked into my apartment, it clicked. Her manic behavior, her stiff body language, her overreaction to the situation...that look.
It was worry. Worry because for the first time in as long as I'd known her, I finally had the upper hand.
That night, as I laid in bed, those sweet, honeyed moans dripped down through Steph's floorboards and into my room for the first time in weeks. I was rock hard, but I didn't touch my cock, not even when that glorious, erotic, short-short-long of Steph's orgasmic release drifted into my ears. Because despite what she had moaned into my ear earlier as she literally had me by the balls, It was me who was in charge now. It was me who had the power.
The warm, spring air felt like gentle hands running through my hair as I drove to church the next morning. All through the service, all I could think about was how drastically the pendulum had shifted with Steph. She talked a big game, and Christ, I'd be lying if I said her dominance over me wasn't a turn on, but the prospect of my step-sister Alex finding out left her clearly mortified. That left me with leverage, and the power made me feel good.
After the service, I scanned the crowd, and was surprised to see Rachel and her family in attendance. It was the first time I had seen her since my cock painted her hands and chest with my cum on the night of her prom. Her eyes met mine quickly, and then she turned away without even a wave. I watched her hands adjust the strap of her bra, shifting her enormous tits together under the front of her sun dress.
Her post-coital exclamation of "Ew, gross" in response to my cum webbing her hands flitted across my mind, but was quickly replaced by a stirring in my loins as I watched the pale flat of her chest begin to blush. She was remembering, just as I was, my fingers in her pussy, my cock in her hands, my cum lashed across her breasts. I knew it. She idly drew her fingers across the neckline of her sundress, across the swell and split of her cleavage. Right where the whip of my hot semen had marked her.
