My sister's friend is a loli

She comes over a lot to hang out with my sister and I can't help but stare and try to get close to her (unowutimeen?)... What should I do?

1. Go for it at their next sleep over!
2. Wait, at least, until she's jailbait.
3. She'll be 18 soon enough.
4. Like ze googles; do nothing.

I don't think he meant soon as in literally soon, since the previous option indicates she's not even jailbait yet.
