I guess he figured that once she laid eyes on his 7 inch yankee doodle, she wouldn't be able to resist and that a 'happy ending' would ensue. The Motel 6 guy actually shared the same ideology. Too much late night Cinemax porn can really fuck with your head these days.
He seems pretty happy about his achievement. Try doing the same thing again except next time stick your cock in her ass first. When she comes up to blow you she won't gag, she'll just puke. It's called "ass 2 mouth". I invented it.
His girlfriend doesn't sound too happy about his poor performance between her legs. They have anesthetic creams that work wonders for premature ejaculation. I'd say buy some.
