j-cup 

One of the best damned boob sizes ever. Famous amongst Japanese bikini models and porn stars.

My last girlfriend, for example, had j-cups. Best titty fuck ever.

Hitomi J-Cup 

Hitomi J-Cup is the most amazing woman alive. She suports the entire Japanese film industry on her J-Cup sized breasts. Without her the world would lose meaning and the milky way would implode into the sun.

Kyle: I don't think I can take living anymore.

Dave: Don't say that Kyle. Here. I have something that will make the pain of losing your entire family and dog in a train accident.

Kyle: What is it?

Dave: It's a DVD of Japanese porn superstar Hitomi J-Cup.

Kyle: I don't think it will help.

Kyles Mum's Ghost: Just watch, Kyle. Just watch...........
