My Half sister part 3

TRIGGER WARNING!!! SEXUAL ASSAULT

One week later

Chris

Sarah had successfully been avoiding me all week since the errr incident where she spotted me with Lisa and I wasn't entirely sure why but I was hoping she was just shy I mean she was just 17 and very obviously a bit of a prude she was our dad's little princess so she was more than a little sheltered. She went to an all girls school the kind that still hosted debutant balls. So obviously she was a bit embarrassed. BUT there was another little whisper in the corner of my mind that told me it wasn't just that. That there was something else something I was struggling to admit even to myself, it was our eyes locking. I had been there granted with a superbly ununique girl but you know I was still in the moment and then I saw Sarah and there was something in her gaze and I couldn't break our look I needed her eyes on me because I was turned on more by who was watching than who I was actually fucking. And that was not good, Sarah being there watching me turned me on like crazy and in my mind it was suddenly her I was with. her warm pussy i was pounding into her firm breasts beneath my hands and as soon as that idea entered my mind I could feel myself starting to come. Very not good and I did not want to analyse that so I was more that happy to just let Sarah avoid me. But as the week came to an end I spotted Sarah passing the kitchen I would ordinarily have let her pass unhindered but I spotted her dress and was going to talk to her!

"hey" I said striding out into the hall.

"oh hi," she said blushing a very fetching crimson that matched her short red dress.

"you look beautiful,"

"thank you,"

"where are you going?"

"just out,"

"thank you that narrows it down."

"I kind of have a date."

"with who"

"just a guy I met in a few of my study forums"

"a blind date,"

"sort of."

"not dressed like that your not." I said sounding surprisingly like my dad.

"I thought I looked beautiful."

"you do, go put on a jacket." a smile broke out across her face,

"OK dad,"

"I am serious get a dam jacket or I'm not letting you out." I said trying to sound firm but Sarah just laughed,

"you going to cut off my pocket money too?"she said playfully

"jacket," she smiled but did go and get a jacket before she returned a car pulled up in the drive I looked through the window there was a silver BMW in the driveway with a preppy grinning behind the wheel it took me 5 seconds to decide I didn't like him or trust him. Sarah scampered past,

"home by 10,"i shouted. Gritting my teeth as she climbed in the car.

I took up station in the den pretending I was reading but in reality I was holding a book while glaring at the driveway gritting my teeth trying to breath slowly and stay calm as the minutes ticked by agonisingly slowly, I wish I had a coherent thought process but I didn't. All I could think about was about the painful twisting in my stomach the hot uncomfortable burning inside me. The anger I wanted Sarah back here now that was it. Ten came and went I stared even harder out the window half past I gave up the pretense of the book and just flung it down staring intently out of the window quarter to eleven the car slowly pulled into the drive I forced myself to stay seated but turned the light off so I could see outside more clearly. Sarah was chatting but looking more than a little uncomfortable he put his hand on her shoulder smiling but she didn't smile and I could see her leaning back from him. He leaned in to kiss her but Sarah smiled shaking her head saying something. My vision turned red as I saw his arms grab her shoulders his fingers making indents in her flesh. He pulled her close kidding her roughly and I was on my feet headed to the door. As I got out the door he was sitting on sarah she was pushing at his shoulders but he held one hand around her throat and I could see her struggling to breathe and with the other hand I was roughly pulling her dress down exposing her breasts. I picked up a large stone from the rockery and just flung it hard a second later it hit his windscreen with a very satisfying crash it didn't shatter but pretty much distroyed it with cracks but more importantly got the dicks attention. He leapt back from Sarah who as just cowering in her chair trembling. I smiled and tapped on the drivers window. The door swung open.

"are you fucking..." he didn't even get out of the car before I fucking punched him straight on the nose which instantly started to stream blood in a very satisfying way and then grabbed his shirt and dragged him uppunching him in the stomach before slamming him into the car.

"Sarah get out of the car." she didn't move, "Sarah house now." she nodded and got out of the car running to the house on trembling legs. I slammed him again into the car again, "you even breath in her direction again I will rip your fucking spine out I swear." I said releasing him. I wanted to carry on beating him up but I was more interested in Sarah so I let him go and turned heading back into the house slamming the door.

I found Sarah up in her room she had already pulled off her beautiful broken dress that was flung in the bin in the corner she was wearing a big sweatshirt her knees pulled up to her chest she was rocking lightly tears streaming down her face. I sat on the bed next to her.

"want to talk about it?" she shook her head so I just put my arm around her shoulder pulling her into my side she silently reached out and lifted my hand running her fingers over my torn knuckles,

"thank you,"

"of course,"

"I didn't tell him you were here so I think he was too surprised to know what to do."

"yeah he didn't seem particularly dynamic,"i nuzzled into the top of Sarah's head. Sarah turned looking up at me.

"do you need anything babes." she shook her head,

"I've got you to protect me."

"always,"

She kept her eyes on mine and I don't know who made the move her or me but suddenly our lips met. Sarah twisted her body around and pressed her body into mine as I stroked my hands across her cheeks and pressed them into her silken hair. Our lips remained locked and I locked her lips my tongue slowly slipping into her mouth. Sarah slid her hands down my arms as she pressed herself into me, I moaned as I felt her breasts press up against my chest.every nerve in my body was super turned on just my this kiss. I brushed my fingers down her neck my hands drawn as if magnetically towards her breasts, as out tongues continued to explore each others mouths. Sarah gave a little throaty moan and my eyes snapped open as my brain suddenly kicked in my thoughts whirring crazily as they fought to catch up. I jumped back from Sarah her face a shocked mask as she was breathing heavily which I knew I was too.

"oh god fuck Sarah that wasn't supposed to happen"

"no no that was me,"

"no I'm so sorry your upset and I."

"I think it was me."

"I was just trying to make you feel better and,"

"look I didn't exactly try to stop you."

"I know but," I stumbled to a halt not sure what I was trying to say.

"I... I better go." I said gently.

"ok" she said but she looked possibly dissapointed as I left.
