oral sex with chocolate in the mouth or genitalia. Giving a sexual sensation and good taste at the same time.
Betty Sue gave her boyfriend Roscoe a chocolate fountain, which ended up covering chocolate all over her face and his lower body.

When having anal sex with another man, you position him so his anus is facing the ceiling. After you climax, pull out quickly, causing feces to rush out towards the ceiling creating the chocolate fountain. Bonus points for receiving a facial from the fountain.
