I can't understand anything in this sentence. Please help


I'm still a beginner learning japanese, so I'm sorry if this is just a stupid
question. I was reading a manga and a character says:

> だめ。シミが浮くとこ見てるから。

I can't understand what he means or what he's referring to... I can understand
the "だめ" part, but what about "シミ" and everything else? Although, I would
really appreciate if someone tells me the meaning of everything here. Thanks
in advance! :)

CONTEXT UPDATE: There are two characters in the page. One of those two says
"If you're going to touch me, do it properly". Then, the other one who's
touching him, says "だめ。シミが浮くとこ見てるから。", and he goes away for a brief moment.
That's everything I can't understand, the "シミが浮くとこ見てるから" part. And yes, he's
saying "シミ" and "浮く". Maybe the artist wrote the words wrong? I think that's a
possibility. Again, thanks in advance!




> 「だめ。シミが浮{う}くとこ見{み}てるから。」

Basically, that can only mean one thing unless it is said in an extremely
ususual context that is beyond my imagination.

> One of those two says "If you're going to touch me, do it properly".

It would have been **_far better_** if you had just given the line in the
original Japanese.

Anyway, 「シミ」 means " ** _skin spots_** ".

「シミが浮く」 is a fairly standard expression meaning " ** _spots form (on one's
skin)_** ".

「とこ」 is the informal form of 「ところ」.

Thus, the sentence in question means:

> "No! 'Coz I've seen spots forming on your skin!"

Unless you miscopied the line, it simply could not mean anything else as far
as grammar and vocabulary are concerned.

The "No!" part would probably mean "No, I can't!"

If you feel this does not fit in the context, you will need to provide further
context and an explanation of the situation, the relationship between these
two persons, etc.
