When your girl blows into your penis and you expel the air in a male queef like fashion.
She coughed while giving me head and I pecker blasted her.
When you ejaculate and put your dick pack into your pants. As the remaining cum leaks out and dries you have to rip it free from your underwear.
Didn't wipe well after sex. Had a real cum ripper when I changed my boxers.
