What does Lucy do next?
Surprisingly Calm
“I need a shower” Lucy said, acting calm even after everything that had happened.
She started to get up off the bed when you reached out your hand to stop her. You wanted to ask her if she was okay with everything that had happened or if she wanted to talk about what the two of you had done but you expected her to either shrug it off, or the conversation ending up in an argument between the two of you. She was the one who wanted to leave and get cleaned up so if she felt the need to ignore the topic then you would go along with her.
“...Let me check the hallway first before you go out. I think Mom is downstairs and Sarah’s still in her room but… just in case” you offered, giving yourself a reason to have stopped her instead of just sitting there with your mouth hanging open.
Lucy’s expression actually softened when she saw you weren’t about to try and convince her otherwise and she stayed behind you as you got up and checked the door. As you expected, the coast was clear, only now a draft of fresh air filled the room to make you both realise how much of your scent you hadn’t realised had been there.
Letting you go out into the hallway first, Lucy balled up her clothes in her arms and walked away from you towards the bathroom. She was still completely naked and was quick on her feet as she headed off to have a shower, letting you get a good view of her ass that you didn’t get to see while she had been lying down. Unlike when you watched Mom earlier, Lucy didn’t turn around, making it to the bathroom as quick as she could and closing the door behind her.
You waited a few seconds to make sure she wasn’t going to pop her head back out of the door and headed to your room, picking up the bag you had left outside in the process. You didn’t hear the shower turn on so you felt safe that she wouldn’t catch you looking at the KDK. She had already caught you looking at Grace’s photos and while you kept the KDK visible for Emma’s convenience, you needed to make sure you were cautious about opening the app.
“What are you doing?”
Startled, you looked up to see Sarah poking her head out of her bedroom as you walked past, too in your own head about your worries when you nearly made them a reality. Luckily you hadn’t been planning on loading up the app on your phone until you got in your room but you were still annoyed at yourself for not being vigilant.
“I’m not that scary” Sarah teased, once she saw your reaction.
“Sorry. I’m just heading back to my room. Why what’s up?” you asked back, trying your best to not get too close to her in case she suspects anything.
Sarah herself wouldn’t care about what you get up to with Lucy but you still felt to keep some of your escapades to yourself…and Emma as that was unavoidable with her dreams.
“Mom is probably gonna call me any minute to set the table and I was getting bored of prepping for tests” Sarah replied with what you assumed to be a casual lie after how she left you and Emma on the street, the both of you keeping a secret that you would rather not question.
You checked the time and saw that it was later than you expected, making your hopes rise when thinking about Lucy potentially levelling up.
“I’ve got a few things to do first but I’ll try and join you downstairs. I also appreciate you having invited Rebecca to have a meal here so I’m planning on bringing that up to Mom” you said, hoping Sarah would back you up once again.
“Does Mom already know about… you know, the two of you?” Sarah asked sheepishly, looking unsure of how to breach the topic.
“She does but I don’t think it will be an issue. At least I’m hoping so” you replied, not having put too much thought into Mom’s reaction.
Lucy was also aware of Rebecca though, so that might be something you have to worry about.
“If you bring it up first as just a ‘teacher’ and don’t use her name, that might make things a bit easier. If they ask then I’ll back you up after that. They’ll probably see it as me taking advantage of your good intentions but I think it will still work” you continued, getting a nod from Sarah as she agreed.
“Alright I can do that. I’ll meet you downstairs then” Sarah responded, leaving her room and giving you a pat on the shoulder as she walked passed.
Not missing an opportunity to watch another of your family members walk away from you, you saw that Sarah had gotten changed and was now wearing some more casual high-waisted running shorts that showed off her toned figure well. The habit of watching their asses as they left was becoming a habit you quite enjoyed and although nobody had taken one of your very first dinner rules to heart, making it acceptable to be naked at home, wearing more form-fitting and revealing clothes was a step in the right direction.
Again, Sarah didn’t check to see if you were looking as she turned to head down the stairs and you headed to your room once she was out of your sight. You finally put down your bag in its usual place for the first time tonight and sat down at your desk, bringing up your phone to finally check the KDK. You tried to lower your expectation but you also knew that if you were close to Lucy levelling up, you still had a chance to fill the rest up during dinner when you said grace so not all hope was lost.
