The Sex Doctor : Best friend crush
Use a soft voice, don't use a deep voice like his, you are not a rapper.
You can say those dirty words to him as you run your hands over his chest and shoulders, but don't let them stray below his waist! And don't forget this, If he still needs a little help getting hard once you've gotten his pants off (though he probably won't), stimulate him with your mouth. Let your hot breath tease him, and gently lick the tip of his member like an ice cream cone, and his cock be standing at attention in no time.
Blend these tips into your lovemaking to spice things up, or use your own methods to get him ready.
