While "Daku" (抱く) can mean sex, it seems the meaning is not as prominent as, say, "Sleep With" in English? It feels like the word is at the same level as trying to imagine "Embrace" or "Hold Me" in a sentence to mean that. I mean, I can imagine, but it's certainly not a walking distance.

On the other hand, the idea of Reimu sprinting over to Marisa carrying a sign saying GEX is just too funny for me to discard. And look at her eyes. Are those the eyes of a creature that is only looking to just cuddle?
