OK, set the metronome to 60 and stroke for two minutes. Imagine being able to kiss me, or see me take my shit off - who knows, I might! ;)
Once your two minutes are up, hands off. Don't touch anything down there. Stare into my eyes, and beg me to let you touch yourself again. Go on, say it out loud.
Come on, be louder than that. Beg me like you mean it. Convince me of how badly you want to have a chance to cum today, and if not, to only pleasure yourself further.
