My Girlfriend's TwinGirlfriend's twin visits for the weekend and the boyfriend sees double

The story

Sofia has news for her boyfriend: Zoe, her sister, is coming for the weekend. He expects a nice houseguest. Then he opens the door to two women who could pass for each other, and Zoe's first line is a teasing complaint that nobody told her he was cute. Sofia tells her sister to behave, and Zoe replies that she makes no promises. The pool opens, the swimwear gets discussed, and Zoe tells her sister that her boyfriend is hot. Sofia knows. He sits there thinking he is in trouble, and he is probably right.

The twist

Episode 2 hands him a bottle of sunscreen. Zoe asks if he would mind helping, and Sofia, always sharing with her sister, says of course. He realizes how dangerous this is, and she asks, with a straight face, whether she should share everything.

Developing story

Mom is due home eventually, the weekend is short and the boyfriend is running out of excuses. Later episodes reveal what happens when both sisters get their way.
