Chapter 5

Riven

I shifted on the bed trying to ignore it pushing the phone down for a second and running a hand through my hair thinking about all the reasons this was stupid I hated how she looked at me like I was the intruder when they moved in and how she fought back every time instead of just staying out of my way like I wanted but my dick didn’t care about any of that it throbbed against my shorts demanding attention and I groaned low cursing under my breath “fuck Izzy what are you doing to me” because I’d been with plenty of girls before hookups after games in the locker room or back at their places easy fun ones who knew the deal no strings just blowing off steam and they were hot sure but none of them stuck in my head like this messing with me even after I tried to push her out of it.

She seemed different fighting and yelling one minute then this vulnerable in the video and it made me curious in a way that pissed me off more because I didn’t want to be interested in my annoying stepsister who barged in and saw me naked and asked that dumb question.

I grabbed my dick through my shorts at first just adjusting telling myself it was nothing but the video was still going on my phone propped up now and she rubbed faster moaning my name again like she was imagining me there with her and I couldn’t take it anymore I shoved my shorts down freeing myself wrapping my hand around my cock and starting to stroke slow matching her pace in the video feeling that familiar grip but thinking about her instead of anyone else. “This is so wrong” I whispered to the empty room but I didn’t stop my hand moving up and down firmer now thumb brushing over the head the way I liked it and I pictured pinning her down after one of our fights shutting her up with my mouth or my hands making her admit she wanted this too even while she called me an asshole.

She’d probably glare and argue the whole time but her body would give in I could tell from how she looked in the video all flushed and desperate and that thought made me stroke faster breathing heavier now sheets twisting around my legs as I got lost in it.

I’d fucked around with so many girls puck bunnies mostly who threw themselves at the team after wins sucking me off quick or riding me hard in cars or hotel beds and it was always good enough to scratch the itch but Izzy felt interesting in a way that bugged me she pushed back didn’t just roll over and take my shit she called me out on being disrespectful to her and her mom and even after I yelled about them being broke or whatever she still stood there staring at me naked like she couldn’t look away.

My hand pumped quicker and now fist tight around my dick as I imagined spreading her legs for real tasting her seeing if she was as wet as she looked in the video licking her until she couldn’t talk back anymore just moaning my name for real instead of in some secret recording. “Izzy” I muttered under my breath not meaning to but it slipped out and I bit my lip trying to hold it in because this was pathetic jerking off to my stepsister’s accidental video but I couldn’t stop now my strokes got rougher and faster hips bucking up into my hand as I thought about grabbing her hips pulling her onto me feeling how tight she’d be around me making her take every inch after she saw it and asked why it was so big like she was shocked but turned on too.

Sweat started beading on my forehead and my free hand gripped the sheets hard phone still playing her sounds low in the background her fingers sliding in and out faster now her moans building and I felt myself getting close trying to stay quiet because the last thing I needed was Mom or Dad hearing anything through the walls but her name came out again louder “Izzy fuck” as I rubbed harder picturing her on top of me grinding down arguing even while she came and that pushed me right to the edge my balls tightening hand flying now slick sounds filling my room mixing with the video. I tried to fight it one last time telling myself to stop this hate her remember how she ruins everything but it was too late my whole body tensed and I came hard groaning her name again not caring anymore thick ropes spilling over my fist and onto my stomach as I rode it out breathing ragged eyes squeezed shut for a second.

When I opened them still catching my breath dick twitching in my hand covered in cum the door creaked open and there she was Izzy standing in the doorway eyes wide staring right at me right at the mess I’d made and the phone still lit up with her video paused now on my bed. I didn’t know how long she’d been there or how much she’d seen or heard me moaning her name like that but her face went bright red and mine probably did too as I froze there not knowing what the hell to do next.
