I swear by God and by the virgin mary that this is true, it just happened:

I've been waiting for the perfect time to act this out. Me and my sister have been sent to live with our grandparents for a period of time, and thankfully they are both senile so we've just been doing whatever we want. I'm over 18 (so i can post here stfu) but I still dont have a car or anything so I am stuck in this house with them.

I've spent most of my time on my laptop or phone, but my little sister is only just entering her teen years and is a very outdoorsy person, so she's been running around and tiring herself out in the wilderness near my granddparents home. I haven't ever slept in the same room as her, and now I can see she's a very heavy sleeper, especially when she's worn out.

I tested the waters the other day by poking her, saying her name, and shaking her arm a little bit. Nothing. fast asleep. So I tried licking my fingers and placing them on her chest to see if she'd wake up because of the cold wetness. No.

So I got the bravery to do what I've wanted to do for a long time: I kissed her. I quickly slinked back to my bed to see if she'd wake up... but she didn't. So I got my PENIS out and touched the head to her lips... that alone was enough to make me want to cum, so I masturbated while kissing her every few moments. It was the best fap of my entire life.

Now I'm back in bed writing this. It's almost 1am here. She's still fast asleep. My sister kissed the head of my PENIS and she doesn't even know it. I feel euphoric
