oh god she's naked

What you didn't notice was that while you were laying down, your sister had decided to take off all of her clothes while you weren't looking.

"...So I guess that means you're still good with this?", you hesitantly inquire. While your reservations have dwindled considerably, Dana is still your sister. You don't want to hurt her mentally any more than she might already be. On top of that, you have your own self preservation to worry about. If it turns out this is all a temporary mental breakdown, what's going to happen to you when she wakes up? Yet, you can't shake the growing feeling this is all too real.

She responds decisively. "Yes, I've never felt more at peace with anything..." She seems so certain, so confident in this, she feels like a completely different sister than who she was yesterday.

"Y'know, you're supposed to be the shy one in our family," you tease. All she does is cutely chuckle in response.

"John, when this first started, I was scared. I thought something about me was wrong, to want this so badly, to believe in these things... But that's only because I didn't know. I thought the idea of doing things with my brother was wrong, that it didn't matter that you had a god attached to you. A sister shouldn't do those kinds of things with her brother, no matter how good the reason, right? But then I did it anyways. And that's okay."

She can't help but have both her smile and her blush become somehow even more pronounced. "It's okay because I'm content now... And I don't know if I'll ever not be content again. I get to live in the same house as my god. Can you believe that? And I convinced their master to let me pay my dues to their body, to pleasure them as they see fit." She begins to gently stroke your member, as if to make her point.

"I'm yours, John. However you want to use me to please your wondrous cock, that's okay. If you only ever want blowjobs, that's okay. If you only want to dominate me, that's okay. If you want me to only watch you do others, that's okay, too." She began to slowly get off her knees and crawl up into the bed onto your lap, lightly wrapping her arms around you.

"But if you want me lovingly, that's okay, too. If you want to impregnate me. If you want to hold me. If you want to kiss me..." she whispers as she kisses you softly. You can still slightly taste yourself on her lips. "Whatever you want from me, master. However you want me to please you..." A pause fills the room. The only sounds you can hear are both yours and your sister's lust-fueled breaths.

You were still taking a moment to process what had just been said. This had gone a little bit farther than what it was before the blowjob. It had evolved from just a singular lust-fueled desire into an entire submission of your sister to you. She didn't want to just make you feel good, she wanted to belong to her god, to have her entire being subjugated under you. Was it okay to even entertain this idea? Your sister had dreams. You knew that. She was about to go off to college, become a nurse, find the love of her life, and get married. If you let her continue, if you let her follow this dangerous path...

Yet, a beautiful woman was sitting on your lap, grinding her pussy against you, and cutely moaning into your ear. You can already tell how aroused she is by the lightly wet feeling growing on your cock. How could you stop yourself? The fear of what you're doing and how you're changing your sister permanently has left you shaking. Even still, you can't stop yourself as you see your own hands wrap around her body and begin to softly rub her back. Your voice catches in your throat for a moment before you speak.
