Easy solution: grab the phone & shove it up her twat. With that hole being occupied, you'll have no choice but to relocate your penis to the nearest available orifice - her anus. I call this "How To Get Anal From A Prostitute Without Paying Extra, by eFukt.com".
This video really hits close to home. I too was once ridiculed for bustin my sloppy goo nuts prematurely. My ego was scarred and so was my penis (herpes). Watching this brings it all back. So to the Hispanic slut who was the most vocal during the humiliation: Space Dock, Strawberry Cheesecake, and a Tony Danza. All for you. All at once.
If your penis is insufficient, watch this video and learn how to give a girl an orgasm so big that she'll giiggle like school girl and love you forever. This would be quite a change for me, most girls just spit in my face after sex. They just can't seem to appreciate ass 2 mouth.
