(Grell) It's ok, I know. You're a naive man. So you push me down on the floor and start breathing hard.
When you hold* me I feel hot, I feel a storm coming~. But everything after that is R-rated.
Oh... Love is such a brute. Don't be so rough or I'll break! No... Aahn!
It's ok, I know. You were aching for this. I'll show you everything, even what is R-rated.
----- *Sometimes the verb "to hold/hug" can also mean "to have sex with", but I don't think this is the case, since the R-rated stuff is coming afterwards, lol.
