When getting a blowjob, and you're about to cum, your grab her by her ears and ram her mouth on your rod as hard as you can and not let her pull back off of it. Then blow your load so hard in her mouth that it comes out her nose and makes her look like an aggravated dragon.
For best results: no sex or mastrubation for at least 2 weeks.
Oh baby that feels so good, keep going
(girl: mm, yeah)
Oh, I'm gonna cum...
(girl: mmummm, LET GO!)
(girl: WTF, it's in my nose)
