I think it's important to have a strong intent. You want to sleep with her so focus on that. Interpret everything that happens between you and her as either an ioi or IOD. And calibrate accordingly. I don't think you need to rely on clever lines. Focus on the underlying tone or "frame" of the conversation. Participate in the small talk if you want but try and have an emotional conversation with her. Tell her you love her, then say you hate her. Tell her you miss her, then you want her to go away. Calibrate your IOIs with IODs and it will create tension from all your mixed signals. Have fun and play with it. End the conversation and then reinitiate later. This has largely to do with the attraction switch of "willingness to emote"
