Advice Needed: I Caught My Stepsister Cumming on My Xbox Remote [M/F] [Voyeurism] [Taboo]

My mom recently remarried, and we’ve been going through the whole awkward “blending of families” song and dance. Honestly, it could be worse. My stepdad Eric is actually pretty cool, and I already knew my stepsister Cassie because we were in the same high school classes before we graduated this spring.

The biggest issue started yesterday. When I caught Cassie … well … *enjoying* my personal belongings.

This ordeal started a week ago, after she and her dad moved into our house. My mom suggested that I share my “love of video games” with my new stepsister. This was a bad idea from the start because before we were in the same family, Cassie once made fun of me for being a “gamer nerd” in front of our 10th grade English class. She probably didn’t even remember doing this, but I sure did.

(She has never played video games … as a pretty, popular kid, she was always busy playing sports or going to post-game parties.)

But whatever. I wanted to keep the peace. So later that evening, I heard a knock on the door of my room and Cassie walked in and collapsed on the bean bag chair on the floor next to me. I looked up from my Overwatch match to glance at her and say a halfhearted “hey.”

Cassie was wearing her usual lounge clothes: a large Victoria’s Secret hoodie and shorts that were so short that they completely disappeared under her oversized shirt.

(Last week she walked through the living room while I was watching TV and when she bent over to pick up her phone charger, I saw she was only wearing underwear under her hoodie. At first I thought she wasn’t wearing anything. Her underwear were light pink, and her thick ass was barely covered. I pretended not to notice, even though it somehow seemed like she wanted me to notice.)

“Our parents think you should teach me video games so we’ll bond and be a real family,” she said without looking up from her phone. Her monotonous voice told me she wasn’t any more excited about this than I was. I tossed my remote on the bean bag next to her. “You can take over,” I said. “Trigger shoots, joysticks move. I’m going to grab some food from the kitchen.”

As I was walking out of the room, the remote rumbled because my team was getting completely killed without me. Out of the corner of my eye, I saw Cassie look up from her phone. “What was that?” she asked curiously. “The remote shakes when you’re getting slaughtered. Get used to it,” I said with a grin. She dramatically stuck her tongue out as I walked out of the room and downstairs.

I wasn’t prepared for what I found when I came back.

The TV was on, and our team was still getting slaughtered. Cassie was still on the bean bag. But now she was laying more on her back, her legs spread, and my Xbox remote was peeking out of the front of my stepsister’s shorts. Her eyes were closed, and she was biting her lip. *What the hell.*

“What the hell?” I said.

I was half whispering because I didn’t want my mom or stepdad to hear downstairs. Cassie opened her eyes momentarily and smiled a devious smile I had never seen before. Just then Tracer, my favorite Overwatch character, got gunned down on the TV screen and I heard the remote vibrate again. Cassie’s eyes rolled back.

“Shut the door,” she said breathlessly. I closed the door and sat back down in my spot on the floor. Suddenly I wasn’t so interested in the pizza rolls I’d brought back.

“W-what are you doing?” I managed.

“What does it *look* like I’m doing?” she said quietly.

“What I mean is why are you doing that with *my* Xbox remote?”

Cassie looked up. “We play video games differently,” she said with a level of confidence that admittedly turned me on. She had a wet spot starting to form on the crotch of her shorts.

“You like to lose games while you’re holding the controller,” she said in a quiet voice. “I like to lose games with the controller pressed against my pussy.”

I completely ignored her insult. It was becoming hard to focus on anything but the growing erection in my shorts and my attempts to hide it from Cassie.

The remove vibrated again, and she squirmed. Her tanned, toned legs shivered a bit, and she was breathing heavier. I had to pretend that this bothered me … complaining felt like what a good stepbrother would do in this situation.

“This is messed up though … you’d be pissed if you came up to your room and I was humping your pillow or something like that,” I said.

“Does this really make you angry?” she said with sarcastic innocence in her voice. “You don’t like watching your horny stepsister make her pussy wet? Something tells me that’s not the case.”

I looked down, and my boner was practically fighting against my shorts. I felt my cheeks blush. This was a game I was losing.

“Just … finish up … I don’t want anyone to walk in and see this,” I said. She nodded.

“I could get off faster if you’d help … help your team lose,” she said as she looked down at the controller and flashed that devious smile again. “Joystick moves,” she said in a mocking tone.

I reluctantly stood up and leaned on the bean bag next to her. She closed her eyes and said, “I’m getting close, but it hasn’t vibrated in a while.” I looked at the screen. At some point while she was humping my remote, her character had drifted away from all the action.

I slowly reached my hand out, toward the controller perched on top of Cassie’s pussy. “You better not cum all over my bean bag,” I said. Cassie nodded her head and bit her lip. “I won’t, promise.”

I guided Tracer back into the heat of battle. This felt wrong on so many levels. Soon we were taking enemy fire and the controller started shaking. Cassie started shaking.

She was whimpering at this point, and she put her hand on mine to press the vibrating controller harder against her clit and pussy lips. She was rolling her hips and grinding against the remote. My remote. And I started to worry that I was going to cum just from watching.

Cassie came just as our character died. She grabbed my free hand and used it to cover her mouth and stifle her moans. Her warm lips were pressed against my palm, and I imagined them pressed against a different part of my body.

A few moments later, Cassie opened her eyes and made eye contact with me. She slowly took my hand back off her mouth to reveal a grateful smile. “Thanks,” she said in between deep breaths. “I needed that.”

She reached down and slowly pulled the controller out of her shorts. Her white cream was visible even in my dimly lit room, dripping down the black plastic. I stood up to grab the paper towel that was next to my abandoned plate of pizza rolls.

When I turned back around, Cassie looked me dead in the eyes. She was licking her cum off the controller.

“Here you go, stepbrother … good as new,” she said. She stood up, pulled her hoodie down over her cum-stained shorts, and handed me the controller. I was speechless.

Cassie walked toward the door to my room with a spring in her step. “You’re welcome, by the way,” she said. “W-what for?” I stammered. “For teaching you how to play video games,” she said with a wink. “I can tell you’re gonna get very good if we do this a few times a week. We can play again tomorrow.”

She glanced down at my hard dick pressed against the front of my shorts and smiled. “Looks like you need to take care of that.” And then she walked out.

Which brings us to now. It’s only about an hour before she gets home from her job. She already told our parents that she “really liked learning to play games,” and they expect me to let her spend the evening in my room again. How the hell should I handle this situation?
