After you pull out and ejaculate on your partner's titties, she proceeds to spread it around on herself, so it's nice and slippery, thus giving an effect similar to lube. This allows you to slide your penis freely between/on/around said titties.
After my boyfriend shot his sticky load all over me, I spread that titty lube around for him to fuck my titties with ease.
