This is what I would do if I was him:
-I would place a hidden camera in my room.
-I would talk to the family about ghosts and tell them I believe there's a supernatural spirit that follows me around (I would do this in several occasions)
-I would act in a subtly provocative way towards the loli to make her understand I was awake when she kissed me and I liked it (without admitting it verbally of course)
-I would wait for her at night and pretend to be asleep once again when she kisses me for a second time just for a second or two and then pretend I wake up and act surprised.
-Regardless of her reaction I would act as if what she has done was wrong, push her back and ask her why she did it.
-Then I would walk towards the camera with a credible expression of disgust on my face and turn the camera off.
-After that, I would show the recording to her and tell her that I'll show it to her parents putting her in a very compromising position.
-Then I would have a loli that not only is attracted to me but also under my full control. I'd coerce her to do everything I want and she'd be forced to satisfy all my deepest fantasies even if she's not ready for all of it yet.
-In the event of her snitching on me, I'd just tell her parents I placed the camera in my room because of my paranoia about this "ghost" that's following me around and I'd also tell them she's bitter and trying to get some sort of revenge by accusing me since I rejected her "love"
Yeah, I wouldn't have gone to reddit and complain like a fucking faggot.
Btw everything I said in this post is a satire and not to be taken seriously by anyone. I would never, and I repeat, NEVER UNDER ANY CIRCUMSTANCES DO ANY OF THE THINGS I'VE SAID IN THIS POST.
