The act of a Mormon inserting the penis inside the vagina without further movement and believing that it is not considered having sex. Therefore the most bullshit way to justify sinning in their religion.
When a Male is done having sex with a Female partner, he avoids washing his dick for a long period of time. During which time he masturbates, marinating his cock with the juices from the vagina.
This chick I fucked last week was so hot, I marinaded my meatstick so I would not lose her sent.
Mike made a Meatstick Marinade after fucking a hot chick. He knew it would be some time before he would get laid again.
