A few days later Riley was watching Tower of God with Lily when they heard Jim calling for Riley. Riley sighed and said I wish he would wait until the end of the episode, its getting good right now.

Lily asked, "Are you dreading it, that you have to satisfy him whenever he wants?" Lily knew Riley didn't have a choice but wanted to know what her other self was feeling.

Riley responded "Honestly no. I mean there is definitely some self loathing afterwards from the fact that he is our big brother. But the sex feels amazing. Jim got a ton of toys and though I was terrified at first some of the vibrators are amazing and he makes me cum like crazy. Not to mention there is something so hot about him being so much bigger and stronger than me. He can pick me up and use me like a flashlight if he wants to, and as demeaning as that sounds, there's something so amazingly hot about it when he does. Plus I can't tell you how much I love how sometimes at night he hugs me from behind and holds me like a cuddle pillow, I feel so safe and can fall right to sleep. That is when he hasn't just creampied me, because then I normally feel sticky and gross and just want to take a shower."

Lily: "But does it not bother you that he does those things with you, well in a way with us?"

Riley: "Not as much as it should. Like I said there is a lot of self loathing involved, but also the more time passes, the more I just want to give into it. There is a part of me, that just wants him to use me as a fucktoy and make me cum. And the more I try to ignore that part, the harder it gets, and the more I want him."

Lily "Wow."

Riley "I know it's crazy, but I better get going, he's probably going to come looking for me if I don't. Besides the faster I satisfy him, the faster we can get back to binge watching Tower of Gods."

Lily: "Sure, see you soon."

Riley left the room and walked down the hall and into Jim's room, closing the door behind her.

Jim: "About time you showed up, what were you doing."

Riley: "We were just watching some Tower of God."

Jim: "Oh, good show, anyway. Let's get started, you've kept me waiting long enough."

With that he picked her up and put her on the bed with an ease that excited her.

Riley: "What are we doing today?"

Jim: "Well, first off, we're gonna do some prep work."

He pulled down his pants and underwear and got on the bed. Then he grabbed a vibrator and turned it on. He put it between her legs and held it against her clit.

Jim: "Now, let's get you warmed up."

As he did this, he leaned over and kissed her neck. She moaned softly and he started licking and sucking her neck. As he did, she began to rub her body against his. He smiled and whispered in her ear, "I think you're ready now."

With that, he reached between her legs and turned the vibrator up a notch.

Riley: "Ahh, ahh. That's good."

Jim: "You like that?"

Riley: "Yes, yes, please don't stop."

Jim: "All right, I won't. Now it's time to try som fun." Jim pulled out a small silicone butt plug with a pink heart shaped jewel on the lubed up and ready to go.

Jim: "We're gonna play a little game. I'm gonna stick this butt plug in your ass, and then we're gonna have sex and see how long it takes for you to cum on your masters cock."

With that, he pulled her legs apart and slipped the plug inside her. She gasped as it entered her.

Jim: "You okay? Is it too big?"

Riley: "It's fine, just change the angle a bit, don't push it straight in, go at an angle."

Jim: "Like this?"

Jim: "Oh, yeah, just like that. It feels so good."

Jim: "Let's get you a little more worked up before we start the real fun."

He took the vibrator and started rubbing it on her clit.

Riley: "Ahh, ahh. Fuck. Yes. That's so good."

Jim: "God, look at you. You're so sexy when you're horny. Now, let's get you a little more excited. He started sucking her nipples, and nibbling on them.

Riley: "Oh god, yes. Oh fuck, please, don't stop."

He did all this as he kept rubbing her clit with the vibrator.

"I can't wait anymore, I'm taking this tight little pussy." Jim said as he got on top of Riley and took her missionary, with the butt plug still in her ass.

Riley: "Ahhh. Fuck. Fuck. It feels so good. Don't stop."

As he fucked her, he took the vibrator and tossed it to the side so it wasn't pressed between them anymore.

Riley: "OH GOD. OHHH. FUCK. I'M GONNA CUM."

Jim: "You're cumming already? That was fast."

Riley: "Oh my god, oh my god, oh my god."

As she came, he kissed her passionately. She could feel his tongue sliding into her mouth.

Riley: "That was amazing. You're amazing."

Jim: "It's not over yet. I'm not done with you."

Meanwhile Lily has been in her room the whole time listening to Jim and Riley having sex. At first she was going to put on headphones like normal so she wouldn't have to listen to them, but this time she didn't. The more she listened the more aroused Lily got and before she realized it her pussy was soaked. Lily couldn't control herself and slipped off her shorts and panties and started masturbating. She started rubbing her pussy as she listened. As Riley said all the naughty things, and how good it felt, Lily imagined being in her place, and how it would feel if Jim was fucking her instead of Riley.

She continued to listen and touch herself as Jim and Riley continued to have sex.

Riley: "Oh god, oh god. Fuck, I'm gonna cum again. I'm cumming. Ahhh, fuck, I'm cumming so hard. Don't stop."

Lily: "Yes, yes, cum for him, cum for my big brother. You little slut."

She was so caught up in what she was doing she didn't realize she had said it out loud. She was about to cum and didn't even care.

Lily: "Ahhh, fuck. I'm gonna cum, oh my god, oh, fuck."

Her pussy was so wet she could barely contain her excitement.

As she was about to cum, Riley was screaming at the top of her lungs, and that's what pushed Lily over the edge. She came harder than she had ever cum before. Her body trembled and her pussy gushed with juices. She laid back on her bed, breathing heavily. She had just had the most amazing orgasm of her life. She had never felt anything like this before. She was completely spent.

After Riley and Jim had finished, he told her she could go back to hanging out with Lily.

That night while laying next to Riley all Lily could think about was the sound of Riley and Jim having sex. She couldn't get it out of her head, the sound of Riley moaning while Jim fucked her and calling Riley his little slut. Lily got so turned on she started masturbating while Riley was laying in bed sleeping right next to her. Trying to stifel her own moans as she rubbed her clit. Lily wanted so bad to see Jim fucking Riley, but Lily had the realization that part of her was jealous of Riley. A part of her wanted Jim to fuck her like he did with Riley while calling her his slut. This thought pushed her over the edge and Lily had another intense orgasm.

Lily cleaned herself up and rolled over to fall asleep. Little did she know that Riley was still awake and was just pretending to be asleep while Lily was masturbating right next to her. Riley couldn't help but smile to herself, she knew how bad Lily was crushing on her big brother, even if Lily didn't want to admit it. And Riley knew how much of a pervert Lily really was. Riley knew she needed to give Lily a push so she could accept it too.
