A beautiful lady who likes to suck dick for hours and lick pussy for days. She is a wonderful, happy, creative individual who deserves only the best. A marykate eventually moves from the UK to the US. A marykate is a great partier and is the queen of perfection. You can't get anyone better and prettier then Marykate. Mkaii is short for Marykate.
Marykate is a sex addict, kinky, wild, lesbian, baby makin', mother fucker.


Mkaii belongs to Alison.

a "Mary Kate" is an ungrateful spineless bitch that acts alot different in public than she does at home. She happens to be a sweetheart on the outside but a cold hearted bitcg when it comes right down to it. she acts differently around different people and can NOT be trusted.
yeah her parents shouldve just named her mary kate
