Rethink, and stay home instead

Now that you think about it, you'd much rather stay home and fuck your family. Brittany has already express her desire to be fucked so you go to find her. When you get to her door, you hear a sound from inside the room. You crack open the door just enough to see what's going on inside. Brittany is laying on her bed nude, fingering her own movie, her eyes focused elsewhere. You follow her gaze to her TV, which is displaying a video of you and Chelsea fucking, a video of exactly what you were doing earlier! You laugh inwardly at the fact that Brittany snuck a cam into Chelsea's room. You mentally photograph the angle the video is from, and you walk over to Chelsea's room. Chelsea is still nude, reading a pron mag on her bed.

"What's up, Bro?" She says. You don't answer but walk over to her window shades, and pluck a small black device from in between two blades in a top corner. You show it to Chelsea.

"It seems like Brittany has been spying on us, Chelsea." Chelsea laughs out loud. "And she's masturbating to it right now." Chelsea eyes open wide and she grins micheviously at you.

"I think you need to punish her," she tells you.

"Yeah I think so. I'll be back in a few hours when she's good and punished.

"Ok, buh-bye." You give her ass a slap and walk back to Britt's room. She's still in there fingering herself while you pound Chelsea on screen. You knock on the door. You hear her gasp, and see her quickly grab the remote and turn off the TV.

"Come in!" She hollers. You open the door. She is lying on her stomach reading a book. It's so tempting for you to just fuck her giant ass right then and there, but you need to draw this out for as long as you can.

"Whatcha doing?" You ask her.

"Just readin'," is her response. You sit down next to her and give her ass a playful smack. She giggles, and before she can react, you grab the remote.

"Wanna watch a show together?" You ask, as you power on the TV. Brittany realizes what you've done and tries to grab the remote from your hands, but you hold it out of reach. "What?" you ask, feigning cluelessness. The TV powers on to reveal a frozen frame of you mid-fuck with Chelsea. "What is this?" You say with pseudo-astonishment.

"Ummmm...." is all she can muster. You push play, and on screen you see yourself start pounding Chelsea's pussy. You widen your eyes to show her how surprised you are. "You videoed me fucking Chelsea?" She can't return your gaze. You pull the cam out of your pocket and hold it up so Brittsny can see it. "With this right?" This last display of evidence breaks her.

"Ok, fine! I was jealous of all this time you spend fucking Chelsea, and how you've never fucked me and-"

"Hold on. I haven't fucked you because you weren't 18 yet. I wasn't allowed. And as much as I wanted to, the price the world paid for inheriting this new concept of free sex was that anyone under 18 was protected. And the world agreed to those terms, so I couldn't fuck you. I would have, you're beautiful, but I physically couldn't. Believe me, I tried, but everytime I tried to come near you with the intent of fucking you, I somehow got turned away. I had to live with waiting until you turned 18."

"I've been 18 for 2 months, and you still have never fucked me!" It was true, she'd only given me a few blowjobs, and I'd forgotten that she was 18 because I was so preoccupied with fucked Chelsea and Mom, I hadn't fucked Brittany yet.

"You're right I'm sorry Britt. I guess I got carried away. Let me make it up to you. Let me be your first."

"Yes, please! Thank you brother!"

"Do you want it in you ass, or your pussy for your first time?" You ask.
