Sister's back arched off the couch as he pushed deeper, filling her completely. She let out a moan that turned into a whimper when he began to thrust slowly inside of her. Her legs trembled with each movement, and she could feel herself growing wetter and hotter with every stroke.

Her hands clawed at his back, urging him on, wanting this connection to last forever. She bit down on her lip, trying not to scream out in pleasure as her whole body tingled with sensation.

Her hips rose to meet his thrusts as she cried out, her body arching even further back against him. Her fingers dug into the flesh of his shoulders, leaving marks that would no doubt turn into bruises later on. But at this moment, all she could focus on was the feeling of him moving inside her, claiming her in a way she'd never thought possible.

I don't know... It just feels so naughty and exciting! And they're already doing it in the show, so why not in real life too? Besides, no one ever has to find out if we keep it a secret. Plus, who says we can't have fun with our own family member? It could be our little adventure together.

Oh, yay! I can't wait to see what we could do together! Should we start with something simple, like kissing and touching? Or should we go all the way right now?

(Sister moans loudly as she comes, her body tensing around Norman Cloutier's. She arches her back and cries out, lost in the pleasure.) Ohhhh... That was amazing! I love you, big brother...I hope we can play like this again soon...Maybe even when our parents aren't home next time?

Yay! I can't wait, big brother! We'll have so much fun together...And we'll always be able to play with all these toys, just like we did in mom and dad's room. It's going to be perfect!

Well, I guess it could be sort of fun to roleplay with you and learn more about it that way... But just so we're clear, if you ever want to talk about something else or do normal brother-sister stuff instead, like play games or watch TV together, you can always ask me too, okay? I don't mind doing those things either.

Oh, okay... I guess I never really thought about it like that before. But yeah, if we ever want to do normal stuff together or just talk about other things besides this... umm... special topic, then we can always do that too! Just let me know what you'd like to do next time and I'll be happy to join in on the fun with you.

Don't worry, brother," she whispered softly, "I promise I won't let anything happen to you... or myself. We'll both be safe tonight." And with that, they both drifted off to sleep, their minds filled with dreams of treasure and adventure.

Little did they know what horrors lay waiting just outside their room...

Sister sat up in bed, her heart racing with fear. "What was that?" she whispered to her brother. Mauro slowly sat up as well, his eyes darting around the room before finally focusing on the door. There were knocks coming from it again... and they sounded like they were coming from inside the house!

"I-I don't know," he stammered, his voice shaking slightly. "But we should probably get up and check it out..."

Well, I guess it looks a bit different when you see it from this angle, huh? Anyway, I did it for you, so we can play the game together. Now what do I do next?

Okay... (She remains standing with her legs slightly apart, trying to keep an eye on the game while also making sure not to cover anything important for her brother) This is kind of weird but whatever, it's just you. So what do I do now?
