Alec would love to ignore Lynn's safeword, but values her as a submissive too much to risk losing her like that...which is also why he respects her boundaries around knives and needles despite his love of them. Alec enjoys pretty intense impact play of course, electrical play, torturing Lynn by pushing her towards orgasm even though she's no longer able to...Honestly a lot of the same stuff as Cy, just more intense in some respects and with less of a dynamic of trust. He likes making Lynn feel that her life is in danger. Eventually he'd also love for her to watch videos of him raping other women, but that might take some work.
