I can get my little one pretty hard with just a few phrases; I suppose if I had the patience to work at it, I could minimize those phrases to just a few words or even perhaps one word.

But I don't have any patience. Once I decide I'm hot, he usually gets to keep his clothes on for about thirty seconds, if that.

I do make him wait to cum until I've decided we're done for the night (because he absolutely cannot stay awake afterwards; I've tried everything), but even then it still takes some work to get him to actually go off.
