Freak Thoughts

I’m currently working on a story about a little girl who is molested and abused at the hands of the babysitters. I’m at the point of the molestation, and am unsure where to go. I don’t know if I should give details, or skim over the event. Similarly, I don’t know if I should just stop it at the point just before the molestation, or continue on and let the girl tell and the molester recieve his punnishment. Here’s  the paragraph I can’t seem to get past:

I asked him if the other girls were going to play, and he said, “No, of course not! They’ll never play with you. You’re naughty. This isn’t a fun game. This is punishment”. And he undid his robe. Usually, he would pull the thing our through his pants hole, but this time he was totally naked. His old wrinkly body still makes me cringe. I can see his body, but no face. Perhaps it was too scary to look at.

Any suggestions???
