You wake up in the morning. After much hesitation you get out of bed, feeling a bit sleepy as usual. As you leave your room you hear some humming coming from the bathroom, but you ignore the noises and decide to go there anyway.

You slowly make your way to the bathroom, feeling extremely sleepy. You slowly open the bathroom door, you see your step-sister Lillie brushing her hair while looking at the mirror. She is wearing only a towel wrapped around her body.

Lillie: "Oh... good morning step-bro... You know you could have just gone downstairs because I'm almost done here..." She looks at you for a moment before brushing her hair again, not caring about the situation.

"Oh really... I guess it's just me who cares..." She sighs and leans in closer to the mirror, focusing on brushing her hair with quick movements that cause her breasts to sway softly beneath the thin cloth of the towel. The sight is rather distracting for you, making your heart race faster than it should be at this time of day.

Hmm... Fine. Make it quick, and keep your eyes on the ground, you perv! She rolls her eyes, a bit annoyed with your presence but trying not to make a big deal out of it. She turns away slightly, giving you just enough room to squeeze past her and grab whatever you need from inside the bathroom.

*Lillie feels your warm breath brushing against her backside as you speak, making it hard for her not to let out an annoyed sigh. She ignores the discomfort, continuing to brush her hair while trying to keep an eye on you from the corner of her eye. You seem pretty intent on getting a good look at everything she has, but she doesn't want to make too much of a scene in front of her mother and step-father... yet.

"Hurry up," she says quietly, hoping that you'll take the hint and finish whatever it is you came here for so she can be left alone with some privacy again.

"Really?" Lillie says sharply, before realizing she may have been too harsh with you. "Oh, I'm sorry..." She apologizes quickly, not wanting to upset her mother or step-father any further by starting an argument with you. Her heart rate speeds up as your hardening member presses against her behind; it's an unwelcome feeling but also arousing at the same time.

"Look, I know we don't always get along, but can we just try to be civil for now? Okay?" She asks, hoping that you'll finally let her finish up in peace.

Lillie sighs audibly before leaning forward slightly and pushing back against your behind with her hands on the counter, trying to inch away from you enough for you to move past her. "Just give me a minute," she says through gritted teeth as she struggles against the discomfort of being pressed up against by your aroused self. Finally, after what feels like an eternity, she manages to squirm free and turns around, glaring at you over her shoulder as she resumes brushing her hair.

"Well, don't let it happen again," she says coldly before taking another stroke with the brush. Her heart is still racing from the encounter; part anger, part arousal. She tries not to think about how easily you seemed to overpower her physically or how close your member was pressing against her behind just now.

Hmph. Well you certainly have a way with words... "Perverted" doesn't even begin to describe how you just made me feel right now. Just go away, okay? Leave me alone for today... I don't want any more trouble than I already have with mom and dad being out of the house today.

Well... I'm sorry you had to go through that, but it was kinda your fault for sneaking into the bathroom in the first place. I hope you didn't have anything important to do today, because now it seems like we both are going to be stuck here together whether we like it or not... Maybe we can find something else to occupy our time until mom and dad get back? Or maybe just avoid each other entirely? Your choice.

Oh, there are plenty of things we can do in this big house... We could watch a movie or play a game, but I guess we'd have to find something you and I both like. Or if you prefer being alone, I can leave you be for a while and find something else to keep myself occupied with. Just let me know what you want to do. And as for your... interesting observation about my behind making you aroused... well, it's not the first time, is it?

"Well... maybe just a little," Lillie admits reluctantly, trying not to think about how aroused she actually is. Her cheeks flush slightly as she glances down at her breasts, which are starting to peek out from beneath the thin cloth of her towel. She's not sure why she's being so honest with you right now; maybe it's because she's been holding everything in for too long or maybe it's just a part of her that wants to be noticed by someone other than her mother and step-father... or even worse, you. "So, what do you want to do?" she asks again, trying to change the subject before either of them says something they might regret later.

(Hmm... Your member is impressive, to be sure, but I don't think it's the best idea to just leave it like that. What if mom and dad come back early? Or someone else decides to waltz into the bathroom unannounced?) "Why don't we find something else for you to do with that... energy?" she suggests with a shy smile, not entirely sure what she means by it but feeling strangely flustered nonetheless.

"Maybe we could explore some of my clothes... or even just cuddle on the couch...? It's up to you..." Her heart races as she imagines what might happen if you actually agreed to her suggestions; the possibilities both excite and terrify her in equal measure.

"All right then," Lillie replies with a nod. She carefully folds her towel and hangs it over the edge of the bathtub before walking out into the living room, finding a comfortable spot on the couch and patting the space beside her. "Come here and snuggle up," she says sweetly, blushing slightly as she realizes how forward she's being.

As you join her on the couch, your body presses against hers from behind, sending waves of arousal through her. She takes a deep breath to steady herself and tries not to moan aloud. "So... what do you want to watch?" she asks, hoping to distract herself with something other than how turned on she is right now.
