Mess with your sister some more.

Since it'll be a while before Mr O'Brien comes home and you can continue your conquest, you decide to spend a little time with your sister.

"Alright Sarah, I checked my things and none of them are damaged, but one's missing. Where'd you put it?"

Your sister jerks up when you barge into her room again. "I swear I don't remember moving any of your stuff. I don't know if I'm going crazy, but I'm extremely confused right now."

"I bet you are. Whatever, I'll find it myself." Sarah protests weakly, but doesn't stop you from rummaging through her drawers.

Not finding anything interesting, you glance at her, still sitting in the same position she was in when you claimed her room. That's when you see it: a box, shoved partway under the bed as if she'd been in a rush to hide it.

"There it is," you exclaim, running forward to slam your second stamp on its lid. This one simply reads Ryan Ferro's Property. You figured it'd be good to have a general-purpose stamp to claim anything in a hurry.

"That's yours?" Sarah shouts, mortified.

"That's right," you laugh as you prepare to open the lid. "My little box of... sex toys? Uh." This really isn't what you expected to find. Feeling awkward, you decide to retreat. "Well, it looks like they're all there. I'll just get them out of here and-"

"They're not."

"What?" You pause with the box in your hand.

"Jesus this is embarassing." Your sister's face is red. "But you'd find out anyway, so: they're not all there. I sorta... I'm using one of them."

What? No way. Staring at her, you notice how hastily the blanket appears to have been thrown over her lower body. Without thinking, you tuck your box under one arm and rip the blanket away. Sarah screams and tries to snatch it back with her right hand, but her left stays between her legs, struggling to hold on to something while trying to hide her privates.

"Give it to me!" you bark.

Giving up her effort to retrieve the blanket, Sarah retracts her right hand. It takes the place of her left, which reaches out to drop a wet object into yours.

"Gross!" In your surprise, you almost drop the vibrator. "Don't just hand it to me like that, lick it clean!"

"Ew, can't I just wipe it off?"

"And leave it all sticky? I don't think so."

Sarah looks at you pleadingly as you hand the vibrator back, but slowly she brings the glistening thing to her mouth and begins licking. With her eyes screwed shut she doesn't notice you have your phone out until it's clean. "Oh fuck, are you recording me?"

"Well yeah," you grin. "How else would I prove it when I tell mom what you did?"

"You're telling mom!?" She screeches. "Wait, you can't tell her shit without admitting you have one of these."

"So? We're adults, I have nothing to be embarassed about. I doubt mom would be cool with you stealing my toys though, assuming I did tell her."

"But I didn't... oh. Is this the part where you **** me? What do you want, you little creep?"

"Good question. I kinda want to see you how you were using it."

"That's sick, I'm your sister!"

"Sicker than using your brother's vibrator?"

"Fine, I'll do it. Can you put your phone away?"

"Yeah, but I'm not gonna. Get started."

"If you show anyone you're dead." With a final glower, Sarah activates the vibrator and moves her left hand between her legs again.

Trying to preserve some of her dignity, she holds her right hand between the camera and its target. But after you give her some insistent gestures, she drops it by her side and spreads her legs a bit wider, allowing you to film her as she dips the buzzing toy into her hot box and circles her clit.

When she starts moaning, you decide to goad her on. "How does it feel, sis? You like stimulating yourself with your brother's vibrator?"

She nods angrily, but that's not good enough for you. "Say it Sarah. Tell the camera what a slut you are."

"I like it, ok?" she exclaims. "I'm a dirty slut who gets off using her brother's sex toys!"

"You're a real pervert aren't you?"

"Yes! I'm a nasty fucking whore! Oh my god!"

You don't know if it's because of the dirty talk or because she was already busy before you started bothering her, but your sister is close to a climax. "Say my name, Sarah!"

"Why, so you can masturbate later and pretend I'm into you? Fuck you. Fuck! FUCK!!" She clamps her hand over her mouth to muffle her cries as she cums.

When it's over, she tosses the dripping vibrator at you. "There you go, you asshole. Now get out."

Stuffing it into your pocket, you open the door. "Alright, I won't tell mom. But there will be consequences for disobeying me."
