My Stepsister Seduced Me!

Kayla and I are sitting in the SUV, my dad and stepmom inside the gas station.

“For real? You have a crush on me?”

I shouldn’t be acting surprised, since my stepsister has been giving me signs ever since she turned 18.

“Yes, I know it might seem weird, since we’re stepbrother and stepsister, but I don’t think it’s weird that I’m interested in guys. That’s normal, right?”

“Yes,” I acknowledge. “I mean, it’s just that you could get practically any guy out there.”

“Ha! Yeah, due to my big tits.”

“Well, I wouldn’t say that,” I hedged, although she made a fair point.

“Pfffft! Uh huh, right…Then tell me, why didn’t guys at my school talk to me before I got tits? No one seemed to acknowledge my existence before my massive bosom growth over that one fateful summer.”

“I see.”

“So, yeah, I know guys want me for superficial reasons; however, I know you’ve been great to me since I was a flat-chested chick.”

My mind is full of emotions, the most pressing being how I’m alone with my stepsister in the backseat of my dad and stepmom’s car, after she has just confessed she’s attracted to me. My thoughts are interrupted when her hand brushes against my crotch. She knows I’m into her, and apparently after all this time living together, she’s ready to capitalize on the chance of having a taboo relationship together.

I’m not sure how to react to Kayla’s confession. I mean, I knew she was attracted to me and I’m definitely attracted to her. She is hot, in a sexy nerd type of way. Even with my ex, I never felt the way I do about Kayla.

“I’m just surprised,” I say.

“Don’t worry, I get it.” She leans in close to my ear, and whispers, “I’ve seen the way you look at me. You want me, too.”

There’s no denying it; she’s right. I lust after her in every way.

“I do want you,” she continues, “but I understand if you don’t feel the same.”

To tease me, she moves her hand away, knowing already she has me like putty in her hand. The front doors open simultaneously and my dad and stepmom plop down in their seats. By now, my manhood is hard as steel, as I can feel Kayla’s lusty glare focused in on me. Dad is getting ready to leave, when he halts. “Baby, did you buy toothpaste?”

“No, I thought you were going to get it,” she responds, annoyed.

“No, we agreed you’d buy it.”

“No, we didn’t!”

Their arguing is short-lived. “Here, come with me, and we can buy the flavor you like!”

Like manna from heaven, they leave the car, once again leaving Kayla and I alone. Her hand creeps back to my crotch, rubbing the bulge through my shorts.

“What are you going to do, Kayla?”

My heart beats rapidly, my mind a torrent of arousal.

“You want me, don’t you, baby?”

I nod, then speak. “Yes, I do.”

“That’s a relief, since I’ve always had a crush on you, big step brother.”

She leans over, kissing me with her sweet lips, everybody in the vicinity unaware of our sordid act. Luckily, our parents are still in the gas station, getting the toothpaste, and probably other shit we don’t truly need.

My heart is beating rapidly, my cock still hard as a rock.

Her hand feels around by crotch, rubbing my bulging erection through my shorts.

“I want you inside me,” she whispers. “But for now, I’ll settle for this.”

Unbuttoning and unzipping my shorts, she stuffs her hand down the front of my pants, her soft fingers wrapping around my shaft, my t-shirt covering her hand, keeping it discreet.

“Mmm, I’ve fantasized about this cock for so long,” she whispers, jerking it through my shorts.

To reciprocate to some extent, I grab her chest, her boobs fuller and better than I imagined they’d be.

“Oh, shit, Mom and Dad are coming out!”

Our lewd groping session ends, my shorts becoming buttoned and zipped once again. My mind is abuzz with desire and I feel as if I’m going to go crazy with lust. My cock is so hard I do not want to continue our road trip with a raging hard-on. Flinging the rear door open, I hop out, tucking my erection into the waistband.

“What are you doing?!? We’re supposed to be going now,” dad says, holding his hands up.

“Sorry, I really gotta use the bathroom! Upset stomach,” I fib.

“Fine, but hurry up! Kayla, you might as well go, too.”

Kayla heeds his advice and we both scurry towards the entrance, aware that using the bathroom is the last thing on our minds. Power walking through the main area, I speed walk to the restroom, opening the door as a wave of relief washes over me that this bathroom is clean as a whistle.

“Hold on, wait for me,” Kayla says, the two of us entering the spacious bathroom as I close and lock the door behind us.

“Hurry, we don’t have much time!”

Wasting no time, we reunite, our tongues dancing together.

I break off, gripping the bottom of her t-shirt and pulling it up, exposing the mocha-hued, silky smooth skin of her stomach.

Raising her arms as I lift the shirt over her head, her shirt ends up on the cold floor. Unclasping her bra and pulling the straps down, her big tits are soon freed from their prison.

They’re even better than I imagined them to be, her nipples hard, jutting out from her chest. Bending my head down, I insert one of her erect nipples into my mouth, playing with it.

“Oh, you have no idea how good that feels,” she coos.

I continue to suck on her nipples, doing my best to please her.

“I can’t wait anymore,” she says, pulling me towards her.

We kiss again, our tongues dancing together once more.

She breaks off, turning around and bending over, sticking her gorgeous ass in the air.

“Fuck me, please!” she moans.

I don’t need to be told twice, reaching between her thighs and rubbing her pussy through her jeans. The heat radiating through can’t be denied, and I can feel how soaked they are.

I quickly pull them down after they’re unbuttoned and unzipped, pooling around her ankles.

“Do it, now,” she whines, slapping her own ass.

I spit on my finger

and rub it around her pussy, coating my finger in her juices.

Curling my finger inside of her, I brush against her vaginal wall, searching for her G-spot, while I reach over and grab her left breast, groping and squeezing it. My cock slides in, her pussy gripping it tight like a vice. Thrusting back and forth, I stuff my stepsister, aroused as hell that we’re fucking in a public place. Faster and faster I go, her orgasm hitting a minute later. My orgasm isn’t far off and I can tell she senses it.

I pull my cock out and shoot my juices onto her ass, while she rubs her own clit, cumming again soon after. We clean up as best as we can, putting ourselves back together before leaving the bathroom. We’re almost to the exit when a random man approaches us.

“It sounded like you two had fun in there.”

“Yes. Yes, we did,” I reply, grinning. “So much fucking fun!”
