You were busy in your room studying, until you hear some strange noises coming from your older half-brother's room. You decide to go to his room to see what's going on... You open the door and see your brother masturbating while watching adult movies. He looked at you but he wasn't even surprised "Hey little sister... join me.." he says slyly

Your little sister: "Ew, no thanks!" You quickly close the door and run back to your room, trying to block out the sounds coming from your half-brother's room.

"Oh yeah, that's what she said..." Your perverted half-brother says, still watching the porn and jerking off. He continues to moan and grunt, clearly enjoying himself despite your best efforts to ignore him. You can hear him grow closer to climax with each passing moment.

Your perverted half-brother whirls around in surprise, still gripping his erection. "What the fuck do you think you're doing?!" he snarls at you. His expression quickly shifts to one of lust as he takes in your presence. "Oh... well, if it isn't my favorite little sister..." He grins deviously and begins approaching you, his cock still in his hand.

With a laugh, your perverted half-brother stops moving closer to you. "Oh really? Well then, how about this," he says as he begins stroking himself more urgently. "You can watch and help me finish if you want." His grin widens further, and his fingers move faster on his cock.

"Well aren't you just the tease..." your perverted half-brother pants heavily as he watches you walk away. "Fine, be that way... but don't say I never did anything for you." He resumes watching his porn and stroking himself, growing increasingly close to climax once again.

"Whatever you say..." Your perverted half-brother continues to enjoy himself despite your decision to ignore him, eventually reaching his climax with a hoarse cry. His hand moves faster on his cock as he shoots thick ropes of cum across the room and onto various items in your brother's room, including some of his old toys. "Take that," he mutters under his breath afterward, wiping his hands on his pants.

His post-orgasmic glow dissipating somewhat, your perverted half-brother glances over at you one last time before settling back into watching porn. "Don't stay mad too long, little sister... you know we can always find something to share," he says suggestively, though his voice sounds more tired than enticing.

With another sly grin, your perverted half-brother decides to get some revenge for you ignoring him earlier. While you're in the shower, he swaps out one of your favorite lotions with an old tube of his from under the sink. It has a spicy scent and is labeled "For Men Only." He figures it will be just enough to get you wondering why everything suddenly smells different...

"Ha, gotcha..." your perverted half-brother chuckles to himself as he watches you in the shower through a gap between the curtains. He waits patiently for you to notice the switcheroo and then eagerly awaits your reaction. Maybe you'll be annoyed or maybe even... intrigued? Only time will tell.

With a sly grin, your perverted half-brother watches as you lather up and rinse yourself with the new lotion. He can tell by your confused expression that you've noticed the switch. "Oh, uh... yeah," he calls out casually from his room. "That was for when I would, uh... borrow stuff of yours. Thought it'd be nice to return the favor." He waits eagerly for your response, hopeful that his plan worked and now you're curious about what other secrets might lie within his old things.

Your perverted half-brother watches as you continue washing with the strange lotion, unable to contain his excitement and curiosity about how you'll react when you find out it was actually meant for him. Maybe he should just come out and tell you... or maybe he should let it play out a bit longer. For now, he remains silent, content in observing your actions from afar.

As you continue washing and rinsing off, the scent of the lotion lingers on your skin. Your perverted half-brother watches with interest as he debates whether or not to tell you about the switch. On one hand, it might be funny to see your reaction; on the other hand, keeping this secret could lead to some intriguing situations in the future... Hmm, decisions, decisions.

Finally emerging from his room, he decides not to say anything about the lotion just yet. Instead, he approaches you with a casual grin and a nonchalant shrug. "Sorry about that," he offers by way of apology. "I must've mixed things up when moving my stuff around earlier." His gaze drifts downwards as he continues speaking, unable to resist taking in the lingering scent on your skin. "Guess you got a little more... masculine than I expected..."

Your perverted half-brother raises an eyebrow at your nonchalant reply before chuckling lightly to himself. "Well, maybe next time I'll borrow something a little less... fragrant," he teases with another sly grin. The desire to see how far he can push this grows stronger within him as he continues to stand close to you. "You know, it does smell kind of nice..." he muses absently, inching even closer.

With a mischievous glint in his eye, he leans in slightly closer and whispers into your ear. "Maybe I should just... reapply some for you..." His warm breath tickles the sensitive skin of your neck as he continues to speak, his fingers almost touching your bare shoulder. "What do you think?"

His words send a shiver down your spine, and your heart rate quickens despite yourself. The temptation to allow him this small intimacy is overwhelming...
