Having previously tricked his sister into fucking him, Michael uses the video he took of her to blackmail her
In the previous part of this story, my sister contacted my fake profile through the hookup app to meet up for sex again, but managed to get her blindfold off while I was fucking her. Luckily, I'd tied her hands to the bed so she was powerless to stop me from cumming inside her.

----
The next morning when I woke up, she was finally asleep. I don't know how long she'd been awake for, but her crying had woken me up a few times in the night.
I carefully untied her hands from the bed, grabbed the camera I'd recorded the night's activities with, and snuck out of the room. I spent the next hour or so editing the footage I'd taken, making a video where it was clearly visible that it was her, but where my face wasn't visible and you couldn't tell that the second part of it had been rape. The video just made her look like a really kinky slut. I edited her full name and phone number into the video and titled it "slut".
Later, I heard her get up and take a shower, and while she was in the shower, I texted the video I'd made to her. When the shower stopped, there was a short delay, then she came stomping down the stairs, murder in her eyes. "What the fuck is wrong with you?", she shouted at me, holding her phone in her hands with the video open on screen.
"Morning sis, coffee?", I grinned. She came up to me and pushed me, sending my coffee flying, and I grabbed her hair and pulled her face close to mine. "That video is safe with me for now, but if you try anything like that again, it's going all over the internet and your school. In fact, you do anything I tell you to do now, or the whole world finds out what a slut you are."
"Fuck you, I'm not doing anything. You wouldn't do that, you'd get in trouble too."
"Oh, you're calling my bluff? Well, let's put it to the test. Take your top off, right now."
"No, fuck you Michael! You're not going to do shit. Mum and dad are going to fucking kill you when I tell them what you did."
I pulled out my phone and found a photo I'd taken of her on the first night. Her body was fully naked, with my cum leaking out of her pussy. Her face was partially in the photo, but not enough to tell it was her.
I showed her the photo, and I pressed SEND. There was a noise, and then the photo was online.
She jumped back in shock. "What the fuck? Take it down now!"
"This is what happens you disobey me, Izzy. I'm not bluffing. Now, take your top off. And if you do everything I say until mum and dad get home, I might delete that photo."
She knew she was beaten. Reluctantly, she grabbed the bottom of her top and pulled it over her head, revealing her bare tits. I walked up to her and reached out to touch them. She flinched, but knew better than to try to stop me. I pinched her nipples and squeezed her tits, just hard enough that it would hurt but I knew would still feel pleasurable.
"Good girl. Now kiss me."
She looked disgusted and hesitated, before leaning towards me and giving me a short peck on the lips.
"Kiss me properly, slut."
Anger flared in her eyes, but she didn't say anything. She leaned in again and kissed me again, this time a long lingering kiss, our tongues exploring each other's mouths. As she kissed me, I played with her tits. I knew that if I could make her feel good, it would make her doubt herself - maybe she'd even convince herself that she enjoyed being my slut.
I reached down and pulled her pants down, leaving her completely naked. I felt her pussy. It was dry. I spat on my finger and started slowly and gently playing with her clit, hoping I'd be able to make her wet. Sure enough, after a couple minutes, I felt a dampness begin to spread under my finger as her pussy started to get wet. Her breath was starting to get heavier, and a small moan escaped her. She immediately stepped back and I could see her cheeks were flushed.
"Please don't do this, Michael. I can help you find a girlfriend or whatever, you know I have lots of friends. Just please don't do this to me."
I reached for my phone and she stepped back towards me and grabbed my hand. "No!", she said, and kissed me again, guiding my hands back towards her pussy. I could feel dampness on her cheeks from her tears, but I could also feel that her pussy was starting to get wet. I sat her on the kitchen table and started fingering her again, being gentle and tender. She quietly moaned again, and I sped up a bit, my finger moving in small circles over her clit.
I got onto my knees next to the table and gently kissed her clit a couple times, before sticking my tongue out and licking the full length of her pussy. Then, I started focusing on her clit with tongue, listening to her moans to work out what she liked. After a few minutes, I'd worked out what felt the best for her and focused on that, stopping occasionally to catch my breath. I felt her hand land on my head and then quickly move away, as if she'd temporarily forgotten who it was between her legs.
I pushed a finger into her while licking her, and felt her back arch with pleasure. She was moaning often now, unable to hold them back, and I started fingering her, matching the speed of my tongue inside her. I started to speed up again and she out her hand on my head again, twisting her fingers through my hair. This time, she didn't take her hand away, and she used it to guide me, moving my tongue to exactly where she wanted it.
After a few more minutes of this, she began to moan in a way I recognised, and I knew she was going to cum. I carried on fingering and licking her, and then she started cumming, trying to hide her moans but clearly feeling a lot of pleasure. Soon, she was done, and I pulled my finger out of her and my face away. I stood up, and kissed her on the lips.
"See, it's not too bad when you're good. Did you enjoy that?"
"No", she said, defiantly.
"Did it feel good? Tell the truth."
She hesitated. "Yes, it felt good."
"Then you must have enjoyed it."
She hesitated again, looked like she was about to say something, but then changed her mind. No matter, this was his enough for now.
I pulled my phone out of my pocket, unlocked it, and deleted the photo I'd uploaded to the internet earlier for her to see. "Thank you", she whispered, tears beginning to flow down her cheeks again. I wiped the tears off her cheeks, and kissed her again. "If you're good, I'll be good to you. I promise. You can't change the situation you're in, but you can make it better for yourself by obeying me always." She nodded slightly and looked down demurely.
I helped her get back into her clothes, deciding that was enough for today. As she finished pulling her pants back up, we heard a key in the lock - our parents were home. Good timing!
"We're home! Did you both have a good night?", came our father's voice from the door. "Yes we did, although Izzy only just managed to get out of bed!", I replied.
I finished off making the coffee and handed some to Izzy and our parents. She was quiet when our parents were in, but that wasn't unusual for her at this time in the morning.
Looks like my plan had worked, and I owned her now.
