The most shameful wank of my life

When I got back upstairs, I didn’t even grab my controller like usual. I just jumped into bed, buried my head in my pillow, and used every ounce of willpower to drive the image of what I’d seen from my mind, while trying to ignore how my trousers were starting to get uncomfortably tight.

When that failed, I hurried to the bathroom and splashed cold water in my face. I sighed as I looked up into the mirror, watching the droplets run down my cheeks. Naturally, my brain and hormones were so fucked that none of it worked. You fucking perv. I pulled my pants down and looked down with disdain at my boner as it sprung free. You prick. Literally. Why are you doing this to me?

Of course, I could have just locked the door, grabbed some lotion and quickly dealt with it. But I couldn’t let myself do that. Not when it would be so obvious what I was going to be thinking about. Not when I would have to look her in the eye afterwards and try to pretend nothing had happened. I would just have to grin and bear it.

But hours later, after I’d spent the rest of the afternoon playing Warzone with a couple of people from my Criminal Law class, and in the evening gone downstairs for dinner, spotted Charley and Mum watching TV and quickly scampered over to grab some leftover Lasagna and brought it back upstairs to my room, I sat in bed with the lights off and still couldn’t get it out of my mind.

I’d pretty much been at half-mast since lunch – but now, sitting here in the dark with my loose pajama bottoms, I was back to being fully hard. This wasn’t going to go away anytime soon. And I knew what I had to do.

Fuck, I just wanted to be done with this. This was why I’d begun to avoid her in the first place.

The thing is, I was just so horny that I wanted to, fuck the consequences. Despite the fact that I knew I would sorely regret it afterwards. I briefly considered grabbing my phone and firing up incognito mode to look for some actual porn to watch, but I knew there was no point.

No, if I was going to get off tonight, it was going to be to my stepsister. Besides, I didn’t really think porn would do it for me right now. I didn’t want some stupid scenario where the girl gets stuck in a washing machine, no nasal ‘What are you doing, stepbro?’.

I just wanted to think about her, trying to imagine what it would be like if it was real. And so, I squirted some lotion on my hand and slowly started to lather it on my rock-hard dick, beginning to stroke it slowly. And then I closed my eyes.

I saw her in bed touching herself, like what had actually happened. But when her eyes opened, she didn’t look shocked, or embarrassed like she had in reality. She just smiled. And I walked over to her like it was nothing, the most natural thing in the world, and took her face in my hands and kissed her. It started off sweet, gentle, but it wasn’t long before it became more passionate and aggressive, as I accepted her tongue into my mouth.

It was time to move this forward, and I ran my fingers down her arm all the way to her fingers, which were still rubbing her clit in earnest. I eased her hand away and used two of my own fingers to slide into her, pushing in and out of her soaking wetness. She moaned into my mouth and began to writhe a bit as I picked up the pace.

I felt a hand on my cock, maybe Charley looking to return the favor, but I was already completely hard. I slowly withdrew my fingers from her snatch, and they glistened despite the dim light, while wet strands from her juices clung to my fingers desperately. I broke off the kiss, and she watched and smirked as I stuck my fingers in my mouth, tasting her. But the smirk didn’t last long – she looked down at my wood, and took it gently in one hand, while shuffling forwards, adjusting her position.

I stared down as I watched it unfold, and she gently rubbed the head of my cock between her lips, her juices covering it completely. She shivered, and I almost came right there – but I managed to stop myself. No way I was going to miss what came next. We locked eyes, and she let go of my shaft as I slowly pushed forward.

Then my door opened, and Charley walked in, focused on something on her phone. Wait ... walked in? She was right in front of me, we were about to … oh no. Oh FUCK.

“Hey, about earlier …” she began. Then she looked up. She saw what I was doing. She stared at me in surprise.

“Uh, I …” I stammered, my brain shutting down. This had to be a joke, a dream. Surely this wasn’t happening to me right now.

“There is no way,” Charley gasped. And then she burst out laughing.

I was so horrified that I literally could not move. I couldn’t formulate a single word. I just sat there, still with one hand wrapped around the base of my well-lotioned cock, staring back at her in shock as she wheezed, clutching her stomach.

I don’t know how long it lasted, but it must have been a while because by the time she calmed herself down, I had gone completely soft.

She took a deep breath and winced, her sides clearly hurting. “Crazy. Have a great night, Luke.” She chuckled one more time, then closed the door.

I must have sat there for at least two hours in the dark with my dick in my hand, wondering whether life is even worth living. Like every guy, I’d experienced my share of post-nut clarity – but this was what I imagined getting hit by a truck felt like, despite the fact that I didn’t even come.

After all the frustration I’d endured today, my sex drive was completely gone. Nonexistent. In fact, I was pretty sure that my penis would never work again. I looked down at it with a mixture of pity and disgust, my soul completely drained of energy.

The thing was … it wasn’t just the guilt. I couldn’t believe she’d laughed.

I guess that settled it – jack off while fantasizing about your stepsister, and the universe will punish you.
