An Orange Creamsuckle is a sex act which involves a person carving a cylindrical hole through the core of an orange, then sliding said orange down the shaft of a penis. Afterwards, you flip a cup of vanilla yogurt upside down onto the top of the penis which is (hopefully) protuding from the top of the orange. If not protruding, see *Micropenis.
My girlfriend hates giving me head because of the bad tastes involved. So, I taught her how to give an Orange Creamsuckle and now we're both happy; she gets dessert and I get the best blowjob of my life. Too bad she still won't swallow #SAD
