When you're standing up, fucking a Latino girl in the ass from behind, and you jam her arm into her birth canal to grab the shape of your penis, and have her jerk it off until cum pours out her ass.
"Ahh maaaan...last night was insane...oh shit I forgot....did you end up fuckin' that old mexican chick?" "Naaaa...I just fed her a handful of expired diet pills and gave her The Panama Canal."
While your fuck buddy is lying on her back, simply kneel with your legs pinning her arms down. Proceed to mouth fuck her. As you are about to climax, simply push her head so that either ear is on the ground, and ejaculate into the other. When she turns her head and tries to get it out, it looks as though the gates of the canal have been let wide open, and everything held behind them is cascading forth in a rush never seen before like man.
He asked Ashley if she would give him head on her back. He then pinned her down and asked her if she'd ever been to Central America. She said no. As he came in her ear, he whispered, "...at least now you've seen the panama canal."
