What's the meaning of these kanji in this image still?


This is a sincere question, I apologize for the lewdeness, though.

I was watching a japanese pornographic film and I stumbled upon this written
phrase. I wanted to know what it means (I'm also starting to study japanese
-not related to the porn, lol-). I attach just the sign so you don't have to
watch the video:

I am able to read hiragana but I can't discern the kanji.

Thanks in advance and again I apologize.
