Sibling bonding

Grace's eyes widen in surprise as you turn her around to face you, her body still trembling from your intense lovemaking. She looks at you with a mix between awe and desire, her cheeks flushed with passion. "I want to be your cockslut, your sister holster for your cock!" she says, her voice barely above a whisper. You grin, pleased with her reaction.

She sticks her hands out, waiting on you to let her wraps it around you neck. Her tongue swirling back and forth, while her eyes remained lovestruck.

"Aw, fuck!" Realizing that you need to silence her, you lean forward. Locking your lips on to hers as her arms wrapped around your body.

As you kiss her, Grace's body goes limp, her breathing slowing down. Her hands slip down from your neck, leaving a trail of kisses as she pulls away from the kiss. You can feel her body trembling slightly, and you know that she's still recovering from the intense orgasm.

Finally after what felt like hours of fucking each other senseless, you cum.

Grace's eyes close as she feels your cum pulse through her body, her body jerking with each spurt. She lets out a soft moan, her lips still pressed against yours. You can feel her heart racing in her chest, and you know that she's still recovering from the intense pleasure. "That was amazing."

"Yeah it was." You ease up from her. "And just think, we can do this anytime we wish and nobody will know."

Grace nods, a smile still on her face. "I can't wait to do it again." She leans in to give you a quick kiss before getting up from the bed. "I need to get cleaned up." You chuckle, knowing that she's already thinking about getting back into bed with you.

Finding it hard to resist, you spank her ass, it jiggles back and forth from the impact. "Hey!" She yells out, a pissed off expression forever prevalent in her face. "This ass is mine, got it?" You squeeze on to it harder. "No other man can use it other than me."

Grace glares at you, her eyes blazing with anger. "You're lucky I love you, or else I'd leave you here with nothing but a sore ass." You can feel the tension in the air as you both stand there, staring at each other.

But you could tell that she was hiding away how taboo this was for her. You let go of her ass, pleased of your accomplishments. Not realizing, that Grace had turned around you felt a painful feeling on your groin. "And this cock is mine and only mind to use, got it?"

"Ow, ow, ow!"

"I said, did you get it?" She says repeating herself a second time.

"YES! Yes, I got it! Can you please take your hands off it before you break it?" You uttered, clearly feeling pain from your erected dick. "Good, good."

However, before you could get back to another intense fuck session. Both you and Grace heard a knock coming from the door. "I'm sorry to do this, miss!" Instantly the door opens, revealing a small and slender man in its wake.

"Hello there, is everything okay?" The man asks, his eyes scanning the room quickly. As he looked around, he was confused. The man could have sworn that another guy was just in here, but there was nobody but him and the main actress, Grace Fulton here. "Yeah, everything's fine," Grace says with a smile, getting up from her chair. "We're starting now, right?" The man nods, his eyes still fixed on the room.

"Uh, y..yeah." he responds back in a confused manner.

"Great, see you there then." She said, her tone was more upbeat than a few minutes ago. What happened here to have caused this? "You coming?"

"Y..yeah I'll be there in a second." The guy scratched his head, before slamming the door shut from behind him.

Luckily for you, the couch was big enough to cover someone like you behind it. As you picked up the remote, instead of watching clips about Marvel girls, you decided to switch towards something more sexier; your sister's movie clips.

(this is how I'm going to end it, you can continue it if you want but I won't be going back to this any time soon.)
