Those aren't condoms. You see, a woman's inner vaginal wall sheds a layer of skin during sexual intercourse, casually known as "the leftovers". Some women shed such a marvelous layer that it actually adheres to the penis in which it is partaking in intercourse with. When you see a guy "pull off a condom", he is actually removing the mucus-like secretion that has coated his penis. When the mucusy layer makes contact with air, it instantly changes it's chemical composition, much like the reaction of watching Elmer's glue dry on the tip of your finger. What you are seeing is a miracle of life Fadista...a miracle...of...life.
