Time to face the music

There wasn't much you could do to avoid your interrogation with your older sister. Even in the unlikely event that you got away from her, Mom was downstairs and she would surely block your escape routes. You briefly considered jumping out of a window before dismissing it just as quickly.

At Lucy’s command, you were directed into her room and onto a desk chair that was among the furniture Mom had kept around after Lucy had moved out. Your chances of escaping were firmly shut down as Lucy locked and shut the door behind her and walked towards you.

She didn't sit down herself and just stood right in front of you with an intimidating look on her face as if pressuring you to confess. She let the silence linger before you attempted to lighten the mood a little.

“So… why’d you **** me in here? Something you wanted to tell me or…” you asked before being cut off.

“Don’t try and play this off! You know exactly why I’ve pulled you in here!” she shouted back.

“Why? What've I done? You’ve only been back a little more than half a day so it can't be that bad.” you replied, doubling down on being clueless.

“Fine, if you're gonna play it like that” she huffed, before turning around and grabbing something from her bedside drawer and throwing it on your lap. “What’s that then?”

You didn't even need to look down to know it was Sarah’s panties that had been thrown at you but you still tried to act like it was your first time seeing them. Well, you were about to but as you were about to speak she cut you off once again.

“If the next words out of your mouth are anything but the truth then I’m going straight to Mom and telling her exactly where I found them and I’m pretty sure neither of us wants to do that do we?” she declared, forcing you to stop and think.

Why would she not want to tell Mom? You understood that she would think Mom was the worst-case scenario for you but involving her seemed like one of the better options for her.

“Fine but why do you have some of Sarah’s underwear in your bedside drawer?” you asked hoping to delay her while you continued to think.

“Sarah’s?” she replied quizzically before grabbing them back off your lap and examining them. Ah shit. Even with a boost in intelligence, you had assumed that she knew they were Sarah’s. Her resistance to telling Mom would make more sense if she assumed they were her own underwear. There’d be a chance Mom would suspect more between the two of you if she went down that route. You could swear you could see her sniffing them once she brought them closer to her face but you already knew of her ‘cum’ fascination thanks to the KDK. A giant grin appeared on her face as she realised she had more leverage on you than she previously thought.

“So they’re Sarah’s huh. And how would you know that?” she replied, holding the panties between two of her fingers and swaying them in your face as if to taunt you.

You were stuck now that you had given her the extra information she needed but like Emma said when you had consulted her before, as long as you give in a little bit, she’ll be in a position where she won’t want to tell Mom. You just needed to find out what her goal was while hopefully giving you as many opportunities as possible to touch her and level her up.

“Fine, I admit it. Sometimes I use Sarah’s underwear when I think I can get away with it and up until this point, Mom and Sarah haven't caught me. You still didn't answer my question though. I hid them pretty well so you must have either known they were there or you were looking for something else so why were you in my room?” you asked, knowing full well that you had pushed her to go in there in the first place.

“Oh please, they weren’t that well hidden. It took me at most 2 minutes to check your mattress and no, I'm not gonna tell you why I was in your room but I think you deserve some punishment for what you've done.” she defiantly replied, avoiding the question and throwing the blame back onto you.

“And what punishment would that be?” you responded, expecting her to be as harsh as possible.

“I believe the punishment should fit the crime, so considering you have already ruined one pair of underwear, you shouldn’t have any trouble ruining another pair right now will you?” she replied, smirking as if she had just come up with the cruelest punishment she could come up with.

“W...What do you mean?” you asked with a stutter, unable to believe she would suggest what you were thinking.

“You're gonna sit there like a good little brother and cum in these panties while I sit here and watch you. If you have no shame using them before then it won't be any more humiliating to do it in front of an audience now will it?” she said with a grin still plastered on her face.

Your eyes grew wide from what she considered a punishment and from your reaction Lucy seemed to believe you were surprised for a different reason.

“That’s right. You should have thought about this before you used them in the first place. If it's too embarrassing for you then I’m sure Mom would love to hear all about this, don't you?” she said, acting smug.

It took you a moment to process what she had put forward and even though it could be a trap, from everything you had heard from her, she genuinely believed that this would be a punishment for you. It was true that it would be a bit embarrassing at first to have to do this with her watching but it would be like a dream come true once you got over the initial bit of anxiety. Hell, the fear you had before she had brought you into the room wouldn't even compare to stripping in front of her.

The problem you saw at the moment was that you would be too eager to get started once you agreed, so Lucy was sure to notice that this wasn't as punishing as she first thought. If you were going to play this right, you needed to still put up some resistance to make sure she didn't suspect anything.

“Please don’t tell Mom. She’d blow this way out of proportion if she found out” you pleaded.

“If you don't think you can handle her knowing then you better get started then haven't you?” Lucy replied.

“Do you really have to watch? I could go to my room and…”

“Nope, I’m gonna need first-hand proof that you’ve actually done as I’ve asked and I know you're smart enough to find a way out of this so I’m gonna have to watch your every move”

You turn your head away from her line of sight in an attempt to hide the smile that was forming from your lips. This ‘interrogation’ had gone completely the opposite way that you thought it would have gone but now that the initial surprise was wearing off, you felt confident that you could somehow push it a little bit further in your favour. You didn't have long to think as Lucy watched you make your decision but your thoughts scrambled to find something you could possibly add.
