lmao no. I never write full scenes for the game. I wouldn't even come up with such bizarre conversation. But it cracked me up, too.
Her lack of love for him. If you didn't cuddle with him during their sex scenes, then she sees Ian as a casual (very pleasant) hook-up, but isn't ready to be in the relationship yet.
After this chapter, I think there's no doubt about it. But I'm not sure it's a proper BDSM since it's basically emotional manipulation and abuse with 2 selfish assholes. Lena's dialogue implies that Axel has always treated her right and made her feel relaxed/free/safe while being with him, yet the first thing he does is doesn't take care about her complaints and forces her to submit. Not in a smooth seductive way but with a brutal hands-on approach. Regardless of how Lena feels about it, how she gets lost in subspace and enjoys herself, this was sexual assault. He pinned her down, restricted her hands and didn't let her escape. That's not how proper doms act unless it's a prepared scenario both consented. Mike and Ian seem to be the only guys capable of handling Lena like a sub while respecting her and caring about her as a person at the same time.
