How do you spend your free time?
Window Shopping
After reviewing the footage and with nobody's spare hands available to help you out, you quickly took care of business before relaxing on your PC. Although the encounter with Mom went as well as it could have, the session left you feeling drained. Something about the new timid attitude she had, really brought a more dominant side out of you that was hard to maintain in long bursts. You’d either get to a point where it felt more natural or Mom would follow your commands without you needing to be direct. Either option put a smile on your face but you'd have to take it one step at a time to reach either of the two outcomes.
With your phone at your side, you decided now would be a good time to review the KDK shop in more detail. You could have dealt with the power-ups that were slowly building up but wanted to save that before you went to sleep. You opened the app and went to the store's front page.
Although there weren't any discounted deals, the items for sale were split up into categories and subcategories to help you sort through them all. As seen in the shop's description the main four were: User upgrades, Subject upgrades, one time effects and KDK upgrades.
User upgrades and subject upgrades were split up further into mental, physical and sexual categories. Sexual contained a mix of the previous two but with a more narrowed down criteria. For example, you could increase your or a subject's general stamina in the physical category but how long you could last in bed? That was sexual. You noticed a couple of general rules as you went along.
Upgrades for yourself seemed to cost twice as much compared to a subject. Increased intelligence for you. 10 points. Increase for a subject. 5 points.
All mental and physical upgrades were usually 10/5 points depending on the person while sexual ones were usually more expensive. Really showed the target audience it was aimed at...
The one-off effects were too varied to group together so that was just a long list of seemingly random effects. There were even variants of the ‘double time’ power-up you received from an achievement available at 25 points each. One that was the same and one that strangely halved the time gained.
And finally, there were KDK upgrades. Most were too expensive for you to buy with the 40 points you currently had and the ones you could afford were pretty simple. The cheaper ones mainly involved adding additional information to a subjects screen. For example, it costs 10 points to reveal the cup size of all present and future subjects. It was information you wanted but didn't really need at the moment.
Some added information caught your attention more than others such as the distance tracker.
Subject: Distance (KDK Upgrade)
Cost: 5 points
Description: This upgrade shows the subject’s distance from the user in metres in the subject status information.
Once unlocked, new items will be available in the shop
Requirements: None
The upgrade wouldn't be useful right away but you could think of a few applications you could use it for. Plus once you started getting more effects that relied on distance, it would probably make up the points spent on it.
Subject: Distance (KDK Upgrade) purchased.
Installing upgrade… 10%...27%... … 87%...100%
Installation complete
Total points remaining: 35
The store now had a new option regarding distance to help narrow down a subject's location but as it cost 25 points you decided against it.
A quick check of everyone’s status screens revealed both Mom and Emma were in close proximity whereas Rebecca was almost a kilometre away. Sarah on the other hand was quickly getting closer as she was presumably being driven home by a friend after her practice. It put a small smile on your face knowing you had at least some knowledge of where everyone was and you hoped Emma couldn't find it too creepy when you told her about it tomorrow.
You left the user and subject upgrades alone for the same reason and thought it best to get her opinion before you impulse-bought something again. You also remembered to switch the KDKs visibility back to inactive now that Emma had gone. Letting Mom see the phone itself was still a no-go so it was more of just a precaution at the moment but if your dinnertime plan came to fruition, it would become more of an issue.
After a few more minutes messing around online and with the KDK, you heard a second car pull up to the house. By the time you got to the window, you saw that both Lucy and Sarah were laughing as they walked up the drive. Presumably, Lucy was the one who picked her up after class so you quickly went down the stairs to greet them. You found Mom in the living room nervously pacing back and forth and although she stopped when she saw you, her anxiety at seeing Lucy again seemed to outway her embarrassment facing you.
“Does everything look good? Does it look dirty to you? What about the floor? Do you think I should vacuum again?” Mom anxiously asked, nitpicking over all the small details of the room that she thought weren’t perfect.
“Relax Mom, Lucy isn't gonna run away if anything is out of place. I’m pretty sure she just wants a friendly welcome from the best Mom in the world.”
Mom seemed to relax at your answer but as soon as she heard Sarah unlocking the door, she began fidgeting with the front of her skirt.
“Tell you what I’ll make it easy for you. If you don’t hug your daughter as soon as she walks through the door, I’ll give you ten more spanks.” you playfully warned.
Mom blushed at your comment but before she could comment back, Sarah and Lucy were already walking through the door. Mom immediately went over to welcome them as she hugged and shared a few minutes coddling over her oldest daughter.
Sarah got out of the way and stood by your side along with a few of Lucy’s suitcases she had brought in from her car. You decided to make yourself useful and took the luggage upstairs to Lucy’s old room while the two of them talked among themselves. It took you a few trips to get it all up there but by the time you finished, their Mother, daughter moment was over and they had both moved further into the house.
Lucy immediately spotted you as you walked down the stairs and came over with an almost sinister smile on her face.
“There’s my favourite guy!” she shouted before wrapping her arm around you and putting you in a headlock. Although you tried to get out of her grip, it seemed her strength had improved while she was away. Or maybe the lack of older sibling bullying over the last couple of years has made you weaker. Either way, you made a mental note to reconsider buying the strength upgrade from the KDK.
With Lucy still holding you tight, she leaned down and whispered to you so Mom and Sarh couldn't hear.
“You still owe me for getting here late so you better make it up to me soon,” she playfully warned.
“Deal, now could you kindly remove your arm from around my neck?” you replied, jabbing her with your elbow.
Now released from your sister’s vice-like grip, you spent a while sitting with everyone while Mom asked Lucy as many questions she could think of. At one point, Mom got up to get dinner out of the oven while Sarah started setting the table.
“Hey I know I already owe you a favour but could you do something for Me as a sort of gift for Sarah?” you asked now that you were relatively alone with Lucy. Although she didn't respond, she gave you a look knowing this wasn't totally for the sake of Sarah.
“Fine, I’ve got a plan to convince Mom to let us have phones, and as you already know I’ve been able to hide mine pretty well up until now so although I won't have to hide it if I can convince her, This benefits Sarah more than it does me” you explained.
“And what makes you think Sarah isn't hiding a phone like you?”
“Well, she wouldn't have been as surprised when she saw I had a phone earlier today and besides, we both know Sarah would just get caught as soon as she phoned one of her friends. She's not exactly what I would call ‘subtle’”.
“Point taken”
Lucy didn't outright say she would agree but you left her to think it over while you took a quick trip to the downstairs bathroom. You fished your phone out of your pocket and loaded up the KDK knowing that the **** contact with your sister had added a new entry.
