Reaping the rewards of our arrangement

After a long day of gaming, I stood in the shower later that evening, eyes closed as I basked in the hot water.

I felt better than I had in while; definitely the best I had since Charley had come back from the US, and honestly maybe even since before that. I’d stayed in my room all day (Let’s not get overly excited, I hadn’t won the lottery), but I’d cleaned it up, aired it out and borrowed a couple scented reed diffuser sticks from my stepmum to make it smell nice.

The reason was pretty obvious. Unfortunately, just as I was thinking about it, the reason came bursting into the bathroom unannounced.

“Charley!” I exclaimed. “It’s occupied!”

“Really, dude? After everything? There’s literally nothing here I haven’t seen before.” She started to look me up and down, so I quickly covered my dick with my hands.

“That’s not the point,” I hissed.

Charley sighed and turned to the sink. “Enlighten me, Luke. What’s the point?”

I looked away, embarrassed. “My willy gets really small in the shower,” I said quietly.

“You are so British,” she laughed. “My willy. Sound like you’re in a Mr. Bean sketch.”

“Fine, let me star-spangled-bannerize it for you,” I scoffed. I carried on in my best American accent. “Dude, my cock gets totally small and shit when I’m in the shower.”

Charley glared at me. “That is not what I sound like.”

“That was a one-to-one rendition of your voice,” I grinned.

“Whatever,” she huffed, turning back to carry on brushing her teeth.

The conversation over now that she was occupied, I leaned my head against the glass shower wall and peered out. She was wearing just an oversized t-shirt that fell below her hips and, I assumed, panties underneath that. I stared in awe at her unblemished, toned legs, following them all the way down to her pedicured feet. Looking up, I saw that she had also removed all her makeup, but she still looked unfairly hot. As she spat out her toothpaste, I started to feel my slightly wrinkly penis start to stir. She couldn’t pull the ‘busy’ card this time, right?

“So … you wanna join me?” I asked, in my best suggestive voice.

She turned to face me, eyebrow raised. “Real smooth, Luke. And no, Mum and Dad are still awake downstairs, it’s too risky.”

“Nah, they’re still watching a film, right? They won’t be able to hear over that and the shower. It’s fine.”

Charley went silent as she considered it for a few seconds. “We’re supposed to be more careful than this,” she said. But then she shrugged. “But okay, sure. Just this once.”

I frowned as she took off her T-shirt and panties dispassionately and stepped into the shower with me. “You could at least pretend to be enthusiastic about it.”

“Oh yeah?” She stepped up to me slowly, shooting me a sultry smile. When she spoke, her voice was low and whispery. “What would you prefer, huh? That I tell you just how turned on I’ve been all day, counting down the hours until I could come home, and you could fuck the shit out of me?”

She didn’t give me a chance to answer, putting a hand around the back of my head and pulling me down into a kiss. I let out a little moan involuntarily as she slowly worked her tongue into my mouth, letting me taste the minty toothpaste she’d just been using.

When she pulled away, I blinked a few times and cleared my throat. “I know you’re making fun of me, but that was really hot.”

“Hmm, affected you much?” she replied, looking down at my erect penis. “Your ‘willy’ isn’t looking so small anymore. And you know, maybe I should pay you back for last night.”

“Pay me back?” I asked, confused.

At least, I was confused until she started kissing her way down my chest, all the way to my waist. “Oh fuck, Charley.”

Finally on her knees, she blew on my cock gently and smirked up at me. “Any objections?”

“God, no.”

“Yeah, that seems about right.”

Not wasting any time, Charley grabbed my cock in one hand and held it up, licking all the way from the base to the tip, and sending a shiver down my spine.

She continued licking around my mushroom head for a few seconds, before leaning forward and enveloping my cock fully with her mouth, almost to the base.

I had to stifle a yelp. The sensation was almost overwhelming – I could feel her soft, wet tongue sliding around on the underside of my shaft, and as she slowly pulled back, she began to bob back and forth, taking me all the way to the entrance of her throat.

I’d never really been that interested in getting head, after horror stories from my friends involving teeth or gag reflexes. Even without that, most people I knew agreed that blowjobs just weren’t as good as the real thing.

But here, with what I was experiencing right now, I couldn’t have disagreed more. Charley was slobbering on my cock how I imagined a pro must do it, her tongue twirling around the head of my penis and gently probing my slit.

‘Oh … Jesus. That feels so fucking good,” I groaned. I didn’t think I was that far off cumming, and she’d only been doing it for about a minute.

Spurred on by my words, Charley picked up the pace, her tongue lathering my cock with her saliva. She moaned softly as she went to town, and the vibrations around the head of my cock almost put me over the edge.

“Ngh … shit,” I grunted. I was on the verge now, doing everything in my power to hold back, but my dick had other ideas. I was going to cum in seconds.

Luckily, she must have felt my wood twitch in her mouth because she suddenly pulled off with a wet ‘pop’, making me gasp. “Nuh-uh,” she said, wiping her mouth with the back of her hand. “You still need to fuck me.”

“Holy shit,” I panted, struggling from the exertion of holding back my orgasm. “I’m guessing that wasn’t your first time doing that.”

Charley raised an eyebrow as she stood up. “Are you calling me a slut, Luke?”

“No! I … uh…” I stammered, no idea how to dig myself out of this hole.

“Because if I am a slut,” she continued, apparently unbothered, “maybe you should do me like one.” She put both her hands on the wall and bent over with her beautiful ass pointed back at me.

I did not need to be told twice. I lined up my cock at her pussy entrance and slowly slid into her with no resistance. I don’t know whether it was the generous coating of saliva already on my dick, or whether she really had been turned on all day like she’d said, but within seconds she felt ridiculously wet.

I stared down at her tight, pink, glistening wet pussy as it enveloped my cock over and over and over. I couldn’t believe that this was the third time I was fucking my stepsister. I would never, ever take this for granted.

I ran my hands up and down her waist as I ploughed into her from behind, getting lost in the moment. Speeding up, my hips began colliding hard with the back of her ass and thighs, the loud clapping echoing around the tiled shower.

“Hey!” Charley looked back over her shoulder to glare at me, though the effect of her **** stare was lessened slightly when I saw how red-faced she was from the sex. “Be careful … ugh … they’re just downstairs!”

‘Uh-huh…” I slowed down my thrusts slightly, but I snaked my hand down to her clit and began rubbing her inflamed clit as I continued to saw in and out of her tight snatch.

“Oh … you asshole,” she moaned. “Fuck … don’t … stop.”

After a few minutes, I could feel myself on the verge of cumming. Honestly, I was surprised I’d lasted this long at all, after the blowjob. It didn’t help that ever since I’d started touching her clit, Charley had been clamping down on my shaft like a vice.

“Charley … ugh … gonna cum.”

She opened her mouth to respond, but it just came out as a yelp. Biting her lip to stifle her moans, her voice finally came out as a low groan, barely audible over the running water and the soft clap of my hips against her cheeks.

“Fine … just go … ahead.”

A second later, I grunted as I pushed all the way in and coated her insides with thick ropes of my cum. Clearly feeling it, Charley shuddered, her pussy juices gushing out as I continued to masturbate her and she came alongside me.

Once I pulled out, I watched, mesmerized, as my thick cum spilled out and ran down her leg, before swirling around in the shower water and disappearing down the drain.

I took a step back and leaned against the other side of the shower, resting my head against the cool tiles. It blew my mind that it was only yesterday that we’d been at the party together. Is this just my life now?

“Is this just … normal for us now?” I asked. “For us to just do it every day?”

“Every day?” Charley turned to face me, laughing. “Dude. I have other shit to do. Besides, Mum is home fairly often, and I’d really rather not take risks like this where possible. I’ll come to you if I’m not busy.”

I paused. “You’ll come to me? Do I just not get a say in what we do?”

“Well, you can always say no if you don’t want to,” she snickered. “But I don’t see that happening, do you?”

Normally I would have pushed back against her bossing me around like that, but I was still coming down from the high of my orgasm. And honestly, she was right. Charley sporadically coming to me for sex wasn’t something I was about to say no to. “Yeah,” I grumbled.

She smiled at me sweetly as she stepped out the shower. “Good boy.”
