You keep making a move on her

"That doesn't necessarily mean that we can't hook up this week Christy," you tell her as you leer at her tight body, dreaming of getting her out of that tight dress and thrusting in and out of her pussy until you cum in her.

"You're a persistent one, aren't you?" she teases you, beginning to flirt back with you as you sit down on the bed next to her, "look, I love my husband very much and I can't take the chance of letting someone fuck me and knock me up. We're trying to get pregnant and I'm very fertile right now."

"MMM...stop...I mean it..." she moans as you kiss her and push her back on the bed, thoughts of you fucking her, cumming in her and getting her pregnant going through your head as you make out with her a little more aggressively.

"I know you want me Christy," you tell her as you bring yourself to stop before you do something that might prevent you from having a shot with her later in the week, "but if you're worried about your husband finding out, why don't you come to the office after hours and we can live dangerously for awhile."

"We'll see," she tells you as you head for the door to prepare to go back to the lobby, "but I hope you understand that even if I do hook up with you, I can't take the risk of letting you cum in me, baby."

"Sure thing Christy," you tell her as you head to the lobby, wondering who else was going to be arriving soon and making a promise to yourself to do whatever you had to do to get Christy pregnant while she was staying there for the week.
