Looking for a manga

read this manga a while ago about a guy whos relative of some sort (cousin or some such) returns from some english speaking country, but turns out she doesnt speak english at all. apparently all she did overseas was have sex and parties and now shes horny again ...

can someone help ... ive been stumped for weeks now ... tried a nr of sights and search engines going through page after page of listings...

wow... thought about it being a meme50 manga but failed to locate it ... thanks so much
