A sexual act in which the male tucks his erection between his legs, bends over and is sucked off from behind. For added effect the female can slap his ass cheeks making them red, and his dong appears as the stem. Not to be confused with the alcoholic drink. Though the former may lead to the latter.
Guy 1: One of them said they was gonna suck my dick from the back. I'm tryin' to see what that be like!
Guy 2: It would look like she's eating a big red Washington apple.
After awaking with a massive erection, masturbate until near ejaculation. Then gently wake up your girlfriend, wife, or transient hooker and commence ejaculation in their barely open eyes.
Wife: Did you just..? Oh my God its everywhere, my eyes are burning! You asshole!
Husband: Behold the beauty of morning glory!
