I surely don't know japanese, specially reading japanese, but looking at the raw maybe it is a pun with the Kanji 'Oboeru' (覚)?
For what I understand the kanji 覚 'oboeru' means to remember, learn or sober up. Read as Oboeru it means to remember, but the MC says: Oboete (覚えて). Maybe he meant he wanted her body to sober up, or he straight said he wanted to have sex with her. I don't know.
The entire phrase was: Karada ni zembu oboete moraitakute.
