I was 18 when I got a step-sister. She turned 18 when I was 20 and I was living at home as I went to a local technical college. Dad worked a lot, when Mom passed when I was a kid, he was amazing and really helped me get through it. He said he'd never find anyone again, told me that my step-mom Janice, a tall, very sexy and beautiful blonde, was mostly a trophy wife but she knew this and didn't care.
As for my step-sister Kendra, she'd grown to be almost a mirror of her mom. We got on quite well, she was pretty shy and was more interested in hanging out with me than socializing with any of her friends but I didn't really pay her much attention and just focused on my school work.
I was sitting browsing on my laptop one morning when Kendra came into my room. She often didn't knock and would come in at random times which made jerking off in the shower the only safe place for me but it was whatever. I liked to wind her up about it. I closed the lid of my laptop when she got close to my desk.
"So, my favorite big brother ever, how are you?" she asked with a big smile.
"Well I could have been in the middle of porn or something but you didn't knock. And I'm your only brother, what do you want?" I replied with a smile.
"Can you please take me to the outlet mall? Mom is working and my license is still suspended. I need some new clothes, I forgot to change the setting on the washer and shrunk half my shirts."
"So you still have half a wardrobe full of shirts, you'll live," I said knowing full well she went through 4 outfits a day.
"You're hilarious, please, I'll pay you, I'll do whatever you want."
"Fine, you're buying lunch, let me shower and I'll be right down."
"I could help you in there."
"Leave, temptress."
She gave me a smile then left, I locked my bedroom door and took a quick shower then found her waiting for me in the kitchen wearing a very tight blouse and a push up bra. She greeted me with a smile.
"You smell really nice," she said when I got close enough.
"You ready?" I replied.
"Yes and I even made you coffee," she said, handing me my travel mug.
"Mmm, you even used one of the good pods, thank you," I replied after taking a sip.
We chatted on the 40 minute or so drive to the outlet mall, I did my best to not notice she had undone a few more of her buttons so was showing a lot more cleavage but I was not blind to the fact she was sexy as hell. I'm sure she noticed me stealing glances but she didn't say anything. I found us a good parking spot then headed inside with her.
The outlet mall was not my favorite place but I was willing to tolerate it for Kendra. She went into one store, didn't find anything she liked so we headed to another. She gathered some outfits in here arms while I wandered a little behind her then to try on then had me go with her to the changing rooms.
"I'm sorry, he can't go in there with you," said the attendant, stopping me.
"He's my brother, I need his opinion," replied Kendra.
"I've heard it before hun, next thing I'm cleaning up a mess. Go in alone or you can both leave the store."
"It's fine, Kendra, I'll wait out here, any you're not sure of just send me a pic," I said.
"Fine," said Kendra and almost snatched the key from the lady.
It took a few minutes for the first picture to come through, it was her in a pretty button-up dress that didn't really suit her. I politely told her so and she sent back a quick 'thanks, I was leaning no'. The next few things looked good on her and I told her so. The next couple of pics took a few minutes, they were all pants and it didn't look like she had any top on but she was cropping the pictures. Then one came through where she didn't. She quickly sent a 'fuck, sorry' but I was still looking at her breasts, they were really beautiful. I freely admit to checking her out in her bikini by the pool but in the picture she was wearing a nice pair of shorts that complimented her hips. Her breasts looked perfect, larger than most girls I'd dated and her nipples were pale and looked hard. I quickly saved the picture then replied to her.
'They look amazing Kendra, shorts look good on you too,' I replied.
'Sorry, I meant to crop the pic, didn't mean to send those.'
'Don't worry about it.'
When she came out of the dressing room she only had 3 items that she didn't keep which she hung on the return rack. She smiled at me but didn't act embarrassed or anything.
"One more store then we can grab some lunch," she said.
"Okay," I replied, trying to keep eye contact.
The next store had the same policy, we didn't even try to fight it since there were signs everywhere so I just sat on the bench and waited. Kendra left a pile of clothes with the lady then went back to get some more and took them all into the booth with her. The first few pictures were normal, she chose well but after a brief delay, she sent me a picture of her in lingerie. It was a white lace bodysuit that was pretty sheer and didn't really hide much. It looked amazing on her and I felt my cock stir in my shorts.
'Um, should you really be sending me this?' I texted her.
'Well, is this one okay or should I get it in black?' she replied.
'That one is great.'
The next few pictures were of another outfit but she sent one front and one back. It was a sheer lace bra and matching thong that looked sexy as hell on her. I was still practically drooling over the pictures when she appeared in front of me, fully dressed.
"Sorry, those last 2 took ages to send. I really like them but I can see you do too," she said with a grin, noticing the tent in my shorts.
"I uh, wasn't expecting those kinds of pictures," I stammered.
"Well, I wanted a man's opinion and I got it. Let's pay for these and we can go get some lunch."
I quickly adjusted myself and followed her to the register, while she paid I discreetly saved the pictures to my phone but I couldn't help wondering what she was up to.
"The food here made me sick last time, can we go to that burger place that's just down the street from here?" said Kendra.
"Sure, you said you were buying right?" I replied.
"Oh, no question. I'm really happy you brought me and helped decide a few outfits."
"Some of them I probably shouldn't have been shown but it's fine."
"Whatever, I bet you downloaded them anyway."
"I... Uh.."
Kendra just laughed.
"I knew it! I don't care, just don't send them to anyone okay?"
Kendra was in a really good mood, we joked and laughed as we had lunch and right as we stepped outside the burger place, she pulled me to her and kissed me. It caught me off guard but I returned her passion. Her face dropped when I stopped it though.
"What's wrong, I know you want this Marcus, I know you like me, why did you pull away?" she said, almost in tears.
"I do like you, more than I should but we can't okay?" I replied.
"No, not okay. Talk to me."
"Can we talk about it on the way home?"
"No, we can talk in the car but I want you to look at me."
We got into my car and I turned to face her, I looked into her beautiful blue eyes and she had tears welling up in them.
"Kendra, you are the most beautiful woman I've ever met. I'm your step-brother, I should be protecting you, not saving pictures of your breasts that you sent to me. My body is telling me I should take you, embrace every inch of your body but we shouldn't," I said, almost convincing myself.
"You know I've been crazy about you since the day we met, right? I don't care that our parents married, we're not blood, you have no reason to not take me. You are amazing, you are kind and you really don't see the man that I do," she replied.
"I... We can't."
"I'm not giving up, I know you felt the same thing I did when I kissed you," she said then put her seatbelt on.
She faced away from me but I could tell she was upset. I felt horrible, I tried to say more but she told me to just take us home and I did. I didn't see much of her for the next day or two, she wasn't answering my messages or requests to talk. When she did, I figured she hadn't changed her mind despite what I said.
I woke up from a great sleep and was in the shower, eyes shut from rinsing the shampoo from my hair and singing along with a song I loved that was blaring from my shower radio. I turned around and almost leaped out of my skin, Kendra had slipped into the shower with me. She was naked and her hair was already wet.
"What the, fucking hell Kendra, scared the shit out of me," I gasped.
"Sorry, I wanted to join you, my shower sucks," she replied.
I made a pathetic attempt to cover myself up.
"Y... You shouldn't be here," I stammered.
"Tell that to your cock, you've had your eyes open for seconds and you're getting hard," she replied as she looked down at it, biting her lip.
"I..."
"No more talking."
I'd love to tell you I resisted pretty hard but I didn't. My beautiful blonde step-sister got to her knees and immediately took my cock into her mouth. Her tongue felt amazing, she had me hard in no time and I knew I'd struggle to hold back. I groaned in pleasure as her head bobbed up and down on my cock, she took me down her throat then swirled her tongue over the tip then looked up at me as she sucked harder. I lost it at that point, looking into her blue eyes and watching the water cascade over her beautiful breasts, I gasped 'I'm gonna cum'. Kendra didn't stop, she kept sucking as my cock swelled then emptied the contents of my full balls into her mouth. She swallowed every drop then stood up.
"Thank you, I enjoyed that," she said.
"I did too," I replied, still catching my breath.
"Water's getting cold, can you drive me to Lisa's later, she'll drive me back."
"Sure, yea."
"Awesome, I'll let you know when."
I turned the water off and watched as she wrapped herself in a towel then left my bathroom. My mind was everywhere, I hadn't had a girlfriend for about 6 months but Kendra was supposed to be off limits. Janice wasn't home so I didn't worry and just carried on with my morning. Kendra came to my room about 2 hours later. She was wearing a nice summer dress, one she'd bought at the outlet mall.
"That looks really good on you," I said.
"Aww, thank you. Are you ready to drive me?" she replied with a smile.
"Sure. Let me grab my sneakers."
