My mother had left my father and I when I was about twelve. A few short years later it just as I was getting used to it being "just us guys" in the house and my dad remarried. My new stepmother was a stunner, a trophy wife if she hadn't been smart and successful, and she brought along a blonde new step sister, Jenna, and while we'd kinda grown up together, mostly our teen years, stepsister or no I could never quite keep my eyes off her.
By the time we turned 18 I realized that regardless of how wrong it might be, my sister was really damn hot. I drank in the sight of her luscious, curvy body, long dirty blonde hair leading the way down past ice blue eyes to a full pair of perky D cup tits, a tight abdomen and waist, and a pert, heart shaped ass over long, toned legs.
She wasn't shy about showing off when she was home from college either, always walking around in a bikini top and shorts, or accidentally leaving her door open when she was changing, letting me catch a quick glance of tanned skin. I even caught her coming out of the shower once by accident, and the mental image of her lovely nude body, her full, perky tits topped with pink, erect nipples was more than enough to keep me up beating my cock for most of the night.
Our relationship changed a little after I caught her. She started being a little more daring with her revealing clothing, leaving her door open, actually walking naked to her room from the bathroom a few times, barely covered by a towel, she had to know I'd catch a glimpse, and it was absolute torture. My step-sister, the queen of the cock teases.
As summer came around, she came back from her junior year at a university upstate that she'd just transferred to, and I'd just gotten home from my own college on the East Coast. Neither of us really had any plans, and most of our friends had ended up taking summer courses or going abroad, leaving us to hang out around the house together, just like old times, till my step mom Sarah asked us to drive out to my Step-Aunt Shannon's place on the coast. She'd had a baby a few months back and wanted Jenna to come help out, Sarah figured I could use the vacation time, and Shannon had mentioned some potential heavy lifting chores for me to do. I didn't really want to give up my summer vacation, but Shannon's place WAS by the coast, and it had a pool.
Which is how I ended up in a SUV driving west with my hot step sister. Jenna was passed out in the passenger seat, her long tanned legs drawn up under her, her tight denim shorts vanishing from view at the bend at her waist, her white tank top was tight and formed around her heavy tits easily, and I must have left the AC on a little high, because her nipples were rock hard against the fabric, holding my gaze enough I swerved a little bit as I realized Jenna wasn't wearing a bra. My pulse quickened a little and I quickly got a raging hardon, my thick eight inch prick wanting to be let loose right then and there... as my step-sister snoozed she shifted a little, flashing the crack of her shorts, revealing the red tinged edges of her pussy framing the lacy black edges of what had to be an extremely tiny thong.
I shifted my cock in my shorts so it was sliding down my pants leg, giving me some much needed relief from the pain of having it pent up, if not quite the release I wanted, the tip of my cock basking in the flow of the cool air flowing past the hem of my shorts felt good too. I sighed and cast another lingering look at Jenna's heaving chest "You're going to get the both of you killed if you keep this up" I said to myself" and refocused myself on the road.
That night at the hotel that marked the halfway point to Shannon's place Jenna had made me turn around, changing quickly into a terry cloth robe that barely covered the tops of her thighs, saying she was going to take a long shower and a bath, then do some girly cosmetic things to refresh herself and get the dust from the road off. I wanted to join her on some level, but somehow I thought stripping down and joining your step sister in the shower wouldn't be at all appropriate, and I was beat from driving all day. So I turned my bed down and lay back to get a wank in.
I'm already sporting half a stiffy as I drop my shorts and take hold of my shaft, thinking about Jenna's lips wrapping around my dick and giving myself a nice hard beating as I pictured those stiff nipples and the rest of her lithe body pressed up against me, that tight cunt I'd only gotten glimpses of pressed against my face or split wide around my thick cock. I was just about to cum when the door to our hotel room opened and Jenna stepped in with a sexy smile on her face. I rushed to cover myself stammering a surprised greeting as my eyes registered the fact that the robe she'd had over her swimsuit had been left poolside, and her wet body was on display, the dark blue one piece with a very low back was tight on her like a second skin, her erect nipples practically trying to shred their way through the fabric, and her mound neatly outlined by the suit as she glistened.
