Kate pulled up to the driveway of her family's modest suburban home and threw her car into park. She looked down at her dark blue tank top. Did a pretty good job of cleaning herself up in the science lab bathroom but in spite of her best efforts there were still a couple cum stains on her chest. She at least was able to mostly clean Mitch's footprint off her skirt.
She looked through the windows on either side of the front door. The larger one had a view into the living room. No one was sitting there. She looked into the dining room through the other window and caught just a glimpse of her mom as she walked into the kitchen. Shit. Kate forgot she was off work today. Hopefully walking through the kitchen to go out back to the garden, she thought to herself.
This was her best chance to make it to the bathroom without seeing her mom. She could explain away the cum stains as ice cream or something but she was sure that she still smelled like sweat and sex. That was harder to explain.
Kate got out of the car and walked up to the door, still feeling sore from earlier. She opened it, not too fast and not too slow. Either one of those would bring more attention than she wanted right now. She walked through the door and made it to the stairs before she heard her mom call from the kitchen.
"Jake is that you?"
"No mom it's me," she replied, loud enough as to not tempt her to come over.
"Oh hi sweetie! How was class?"
"It was fine," she said as she started to make her ascent up the stairs. She heard her mom start walking towards the stairs so she calmly started to pick up her pace until she finally made it up and around the corner into the hall.
"Hey! Where are you going?"
"It was so hot out today and I'm feelin' a little sweaty and gross. I was gonna hop in the shower."
"Well can I see my beautiful daughter's face?"
Face. I can do that, she thought. She poked just her head around the corner at the top of the stairs.
"Here it is in all it's glory," she said, giving a big exaggerated smile.
Her mom was at the bottom of the stairs. She puffed air out of her nose and smiled a bit.
"I can't tell if you're in a good mood or a bad one."
"Honestly feeling pretty good!" She meant it. She didn't get into details why.
"That's what I like to hear!" she said. Kate studied her face for just a moment. She really was a spitting image of her mom. Nearly the same height, same hair color, same nose. Just like Kate, her mom was cute.
"Alright well... I'll be in the garden if you need me."
"Okay!" She pulled her head back into the hall and took a few steps before her mom yelled to her again.
"Oh and keep an eye out for your brother! He should be coming home soon!"
"I will!" she replied before stopping in her room to toss her notebook on the bed and then making her way into the bathroom.
Jake sat quietly in his best friend Mike's car. They were slowly making their way down the rolling suburban streets to Jake's house. Mike was droning on about the losing streak he had in Apex Legends last night as Jake smiled and nodded along. Mike talked a lot and Jake didn't, so naturally the two were a great compliment to each other. Normally, Jake would be listening to Mike for real but today he found it hard to focus.
"I want you to take whatever you want from your big sister, J."
Katie's words echoed in his mind.
Jake didn't always hitch a ride home with Mike. Only usually when he was in a hurry. He told Mike that he was trying to catch a livestream. He lied, but there was no way in hell he was gonna tell him the truth.
The truth was he wanted time alone in the house with his sister. He spent most of his day trying to hide the boners he got just daydreaming about the possibilities. It was hard to think about anything else, even now as Mike rambled on to him. At this point Jake wasn't even sure what subject he had moved on to. He checked his watch. Katie should be home already.
"So are you in?"
Jake crashed back to reality. "In what?"
"Dude were you even paying attention?"
It took a lot for Mike to realize someone wasn't paying attention. Oops.
"Sorry, I'm just feeling a little carsick I think."
"Well you better not be normal sick. Birthday party. My place. Tomorrow night. Are you in?"
"Wasn't your birthday a couple weeks ago?"
"That's what I was
sayin'
. We're having a
real
party tomorrow night. Parents are out of town."
"Oh for real?"
"Yeah for real! So..."
"I'm there man. For sure." They pulled up to Jake's house.
"Alright awesome. Well I'll see ya at school tomorrow."
"Yeah see ya later."
Jake stepped out and closed the door and Mike drove away, turning up his music as he did. Jake noticed the car in the drive way. Katie's car.
Fuck yes, he thought. He immediately started getting hard and tucked himself to make it in the house without committing a crime.
He quickly jogged up the walkway to the front door and slipped inside.
Katie looked at herself in the mirror. Her finger traced a cum stain on the collar of her high neck tank top.
Hopefully mom didn't notice that, she thought to herself.
She walked over to the shower and turned it on. It was a typical shower and bathtub combo with a floral curtain. She set the water as hot as it would go before walking back to the large mirror in front of the sink and flipping the switch for the obnoxiously loud air vent.
Katie began to undress. Staring with her socks, and then moving onto her skirt and finally her shirt. She turned on the sink and soaked her shirt in water and hand soap. That should do it, she thought.
She looked back up into the mirror and into her own eyes before looking down at her tits. Nobody's seen them since I got my... gift? She didn't know a better way to put it than that, but she wasn't interested in spending too much time thinking about it. But so far since last night? Creampied by her little brother and covered in cum by Mitch. She was excited. She had ideas for what would be next but nothing concrete. She only knew she wanted the list to grow and that it would.
After admiring her figure one last time in the mirror, Katie stepped into the shower.
Jake didn't see Katie immediately. He looked around the living room and peaked into the kitchen but she was nowhere to be found in the first floor. It was only when he started heading upstairs to his room that he heard the shower running.
Okay okay. She's already naked in there, he thought. This is perfect.
He had butterflies in his stomach and he was hard as a rock, but a part of him was still afraid. What if she was lying? Or just reconsidered? Sure, they had sex but like, what if she just said that stuff to turn him on and didn't mean it? He reminded himself of her wink and when she flashed her ass at him.
Only one way to find out. That's what she said.
Jake tossed his backpack in the room and walked to the bathroom door. He could hear the water running clearly now, along with the bathroom air vent. He thought about the water and soap caressing her thighs and her tits. He thought about his sister using her loofa to wash her crotch, making sure her pussy was pristine for anyone who decided to come in and see it.
He held the door handle for just a bit longer before turning it and walking inside, closing the door behind him, his heart beating faster and faster.
