How does Grace react?
A spell has lifted
“We really shouldn’t have done that. I don’t know what came over me” Grace admitted with a panic, making you quickly stop relaxing and move to resolve the situation before it got out of hand.
“Don’t worry it’s fine. Everything’s fine” you reassured, getting her to actually look at you again before continuing.
“Were both consenting adults right and nobody got hurt. You were just helping me when you thought I needed it. Nothing more nothing less. Think of it as an extension of our practice session earlier” you explained, seeing that your words were getting through to her.
“Right, right” Grace admitted, calming down until she looked down to see your cum still dripping off her fingers, seeing that she was in such a compromising position.
Her cheeks flushed as she saw how much she was revealing by being naked in front of you, still getting excited via her Kink but showing off a bit too much for her to be comfortable right now.
“I-I think it’s best if I still leave you to your shower” Grace said, letting the spray of the shower wash her hands and trying to wipe her stomach clean.
“Sorry about that” you apologised, seeing her have some trouble.
“No it’s fine honestly, I did say to… Umm… sorry but could you turn around while I get out?” Grace asked in embarrassment, not wanting to repeat what she had said in the heat of the moment.
You gladly turned around to let her get out without prying eyes, knowing it would be best if you co-operated at the moment. With you now facing the shower again, you got to bring your eyes down and get a proper look at Emma for the first time in a while, finding that she was still keeping her eyes on her mother instead of you. Once she saw you were looking however, did she let a grin appear on her face.
“We should do this more often” she teased, almost letting out a laugh as she continued to keep an eye on Grace while you couldn’t.
Grace seemed to be still standing behind you and hadn’t left the shower, making you curious as to what she was still doing. Without being able to turn around, you moved to one side of the shower, letting Emma get a better view of Grace while you couldn’t.
You waited for Emma to hopefully relay what she was seeing but all you were met with was silence, Emma’s eyes only going wide after you heard Grace take a few quick steps away from you. Her steps left the shower and a few moments after that, the sounds of the door opening and closing was enough to make you turn around and confirm it was just you and Emma now in the room.
“What happened?” you asked Emma with a whisper, curious about what she did but still keeping your voice down in case Grace was nearby.
“S-she tried some of your cum. She didn’t even hesitate and then ran one of her fingers through some that was still on her stomach. I didn’t think she… That’s more of a Lucy thing right?” Emma asked looking surprised at Grace’s actions.
You yourself didn’t think it was that weird at first as your cum now supposedly had a better flavour but then again, everyone else who had tried your cum had done it because you had either wanted them to or they had received a facial. With Grace being the first to do it of her own will, it was almost certain in your mind that the new group passive effect on the KDK was now affecting everyone which included Lucy’s shared kink.
Lucy Cooper - Subjects have less aversion to the User’s cum being on/in them and the scent/sight of it in the surroundings will increase arousal. Reaction to seeing cum on other subjects is not ignored and subjects will act the same as previously if spotted.
Given Emma’s reaction, it seemed that the second half of the description was also in full effect reminding you that you had never updated Emma with the latest about the KDK, only showing her half naked pictures of Grace when she was leaving yesterday evening.
“I think I know why but I’ll explain when we get out. I do think I still need a proper shower before we both end up all wrinkly” you joked, holding out your arm to help Emma to her feet.
With the two of you having recently orgasmed, you didn’t get too hot and heavy after that, only a few minutes of making out and some light groping from the both of you. The two of you left the shower feeling just as excited as you did entering it and now came the time for you to explain everything once you were dry.
First, you went over the intelligence and the kissing upgrades that you had given her last night, with her commenting that she had noticed the change when you made out earlier but she still hadn’t had the chance to fully explore the full effects of what had changed regarding her intelligence.
Next came the two bigger pieces of news, the group passive effect and the hidden effects. The passive effect excited her when thinking about how other subjects would be changed but the fact that she had five other minor changes added overnight from all the other subjects would surprise anyone. She seemed slightly taken aback by the change given that she hadn’t noticed anything herself but given that she now knew what those effects would be, she was able to accept it.
Then the hidden effects… You realised this probably wasn’t the time to be discussing something this serious while you were both still naked in the bathroom but with what you had planned for the rest of the day, you didn’t think you would find much time to be alone with her until at least after school, maybe later.
You only knew Sarah’s hidden effect so far and that did help clear up some confusion for Emma when she was disagreeing with Sarah about prom yesterday evening. As for the other five effects, Emma was as clueless as you for any of them including her own but she promised to think about it in more depth to see if she had noticed any strange changes in her behaviour since you got the KDK. You had spent a lot more time with all the other subjects than her and you hadn’t spotted anything, so for now you thought she wouldn’t have any suggestions, only hoping that she would be another set of eyes to keep a lookout in the future.
With the majority of what you wanted to discuss now explained, you both left the bathroom. Emma still didn’t have to worry about being spotted with the invisible effect still being active, so she was happy to go naked towards her room and let the effect deactivate when she started getting dressed, a decision you were happy with given the extra eye candy you got.
On the other hand, you realised that you had left your spare change of clothes downstairs in your bag, making you and Emma go off in separate directions to complete the rest of your own morning routines.
Author's note: I'm never really good at special events but I've decided to realise a double chapter for the 200th chapter. 200 + 201 are now available on Patreon and both will be available on Chyoa on Thursday to catch up so if you want a bit more KDK a bit early, head on over :D
Are you able to find your clothes?
