She give you a present

Only a few minutes into the drive, your sister takes off her seatbelt and unbuckles your pants. She kneels on her seat and takes your soft dick into her mouth. With her efforts, it quickly grew to full mast inside her mouth.

Her head rose and fell. It felt amazing. You decide to return the favor by reaching over her and fingering her ass. You had your suspicions from the park, but this confirmed it. Your little Sister was seriously turned on by her ass.

It was difficult to focus on driving a two ton vehicle through the streets without hitting anything, but you managed. You pulled into the driveway of your house, but Sarah clearly wasn't done.

She continued to gag herself on your cock. You felt yourself getting closer to the end. You put another finger into her ass and fingered her deeper. In just moments, she was cumming, as were you. Her throat was milking you. Her ass clamped down on your fingers, preventing you from withdrawing them.

Only a minute passed before she came back to reality. She sat back up, your semi-hard cock slipping out of her throat. She hadn't spilled a drop, not that she could've. Your cock was so far inside her throat, all of your cum went straight into her stomach.

"That was amazing. Thank you, Sarah."

"Anytime brother!" She grinned, opening her door.

"Wait!"

Sarah stopped and closed her door, looking at you confused.

"Give me your clothes. I want you to walk back inside naked."

"Ok." She begins to strip.

"When you get inside, I want you to make out with Lora. Only then are you allowed to wear any clothing."

She smiled as she gave you her clothes. "Yes master."

Your sister opened the car door and stepped out completely naked. She didn't dare to cover herself, and she casually walked inside. You sat there watching her tight ass walk up to the door before disappearing inside.

Only then did you follow her. You noticed that the neighbor's son was mowing the lawn across the street. He had stopped to watch your sister. You chuckled as you remembered that he had graduated just a year before.

Inside, right in the kitchen, your naked sister was making out with your third mother. Lora certainly wasn't against it. Her hands were resting on Sarah's ass cheeks, squeezing the sexy cheeks. You watched for several minutes before Sarah disengaged, smiled at Lora then you, and disappeared upstairs.

Lora watched her go before she sighed and sat down at the table. You sat down with her.

"Kyle, you are amazing."

"How so?"

"Just yesterday, she was too shy to even be naked in front of anyone else. Now, she naked outside in public and making out with me."

"She is good at it, isn't she?"

"You know damn well she is. It took everything I had not to throw her on the table and eat her out. If she hadn't broken it off when she did, that's exactly what I would've done!"

You could see that Lora's bra had slipped slightly, revealing a nipple. You could also see her hand moving between her legs.

You stand up and walk behind her, whispering in her ear, "Maybe I'll let you watch when I plow her next." You leave, giving her exposed nipple a slight pinch.

She yelps, but doesn't do anything. You walk upstairs, but from the sounds in the kitchen, Lora was attempting to finger her frustration out.

You make a quick stop in the laundry room to start the load of Sarah's clothes. Then you walk into your room. Sarah is there, putting on a loose shirt and skirt. You notice she didn't bother with underwear.

Your sister looks at you for a moment before continuing to look at herself in the mirror.

You sit down at your desk. "What is with girls and mirrors? I swear, you girls always spend a ton of time in front of them."

Sarah chuckles, but doesn't look away. "I don't know about others. But I spend a lot of time in front of mirrors to make sure I'm sexy enough for my master."

Your manhood twitches at the word master, but it is tired from the previous activities. You know that you could get it up, endlessly even, but you do have work to be done. The God had made it, so you never run out of sexual stamina.

"Glad to know! Unfortunately, I have to get some work done. You are free to stay, but I do have to focus, so no fun this time."

"Oh don't worry. I am exhausted. I'll probably just lay on the bed with my phone for a little bit."

"Ok." You boot up your computer and get to work.

Just like she said, she laid on your bed on her phone. When you got up to get some water, you noticed that the skirt had flipped over, exposing her naked ass and pussy. Returning to your computer, you slap her ass on the way, making her yelp. You continue your research and plans. When Sarah hears the parents return, she zips out of the room to welcome them.

You love having your sister in the room, especially when she is half naked and exposed. However, there are some things you need to do that you prefer to not have her know about yet. Now that she was gone, you contact some people and make some money transfers. One particular phone call lasted several hours, until Lora called that dinner was ready.

You quickly finished with the woman on the other end of the call, making an appointment for the next day to finish up their business. Hanging up, you breathed a sigh of relief. This particular bit of business was critical to your plans to ensure your family's safety and continued happiness, but one wrong move could destroy everything.

Standing up and stretching a little, you strip out of your clothes and toss them into the hamper. You put on some boxers briefs and head downstairs.
