Tell her she looks gorgeous.

"Not at all!" you say, acting as suavely as possible, "you look gorgeous!"

She blushes and smiles. "Why thank you! Oh!" She gives a start of recognition. "So you must be why Belinda suddenly gave me the night off. I was wondering. I must remember to thank her. So what did you want to do?"

While you are considering, the two of you suddenly hear a muffled scream coming from the room down the hall. "What was that?" you say.

"Oh, don't worry about it," Molly says. "It's just, uh, one of the maids. Come on, let's go to the main house."

The two of you walk and Molly starts thinking out loud. "We can't really go anywhere since Belinda has my car. I suppose we could watch a movie or something. Wait! I know! Why don't we go to the game room and play some games?"

"Sure!" you say. "That sounds good to me."

The two of you make your way to the game room. You'd seen it briefly on your tour of the house, but didn't quite take it in. There's a pool table, a ping-pong table, a dartboard, and tables with lots of games neatly stacked on shelves. There's even a jukebox, a couple of pinball machines, and a lightly stocked bar.

Molly draws you each a beer, selects some songs on the jukebox, and the two of you play a succession of games. She's pretty good at all of them, but you more than hold your own, though you sometimes wonder if she might be holding back a little.

Molly is quite an interesting conversationalist, seemingly able to talk about just about any subject and you really enjoy your time together and playing games. After finishing a few games of pool, a few games of ping-pong, some darts, and some pinball, the two of you sit at a table, drinking some beer, and look over the shelves of games.

"Do you play chess?" Molly says. In fact, your father taught you to play chess and you actually pride yourself about it a bit. You certainly can beat most of the kids in school most of the time, though you've never seriously studied it.

"Sure," you say.

She gets out the chess set. She takes one pawn of each color and hides them in her hands so you can select one. You pick her right hand and she reveals a white pawn, which makes you happy. Starting off with an advantage is never a bad thing, you figure. She plays pretty well, but by mid-game, you have a small advantage and she makes a surprising blunder which allows you to capture a rook uncontested. You're able to turn this into a checkmate pretty quickly.

"Wow! You're really good, sir!" Molly says. "Would you like to play again? Maybe make it interesting?"

"What did you have in mind?" you say, feeling a little cocky, but also knowing she'll be playing white next game.

"How about if I win, you fuck me and if you win or draw, you can do whatever you want with me?"

"Anything?" you say. Since you get to have sex with her, win, lose, or draw, there seems to be no downside to this deal.

"Sure. I trust you," she says.

"All right. It's a bet," you reply.
