That's the sort of unrealistic fetish usually relegated to extreme porn or bad erotic writing (fair enough, very common in a lot of badly written games on here). I wouldn't generally call it playful & it's actually the kind of thing I'd rather avoid in these stories, only partially because of that implausibility*. (I mean, if your partner considers you "worthless", why the hell are you together? It takes out all the tension and push/pull dynamic, too. If the relationship isn't worth it, there are no stakes = Not interesting).

I was thinking more along the lines of her being a big slut "that can't help herself" & playfully teasing about all the big cocks she can't resist filling her up, like some of the dialogue at the end of Chapter 10, which an astute Lena may interpret turns the right kind of Ian on. The turn towards meanness I detect that path heading towards is exactly what I didn't want. Helpless nymphos with a heart of gold, gobbling 10 cocks FTW.
The parenthesis sums it up pretty well for me. If the relevant events/paths of chapter 10 are written to their end in the typical uninventive, everything-has-to-gradually-escalate porn game kind of way, we can expect something similar as in GGGB, with no other reason for them to be together than a sadistic meanness on Lena's part, as you mentioned. (Ian, in his involuntary celibacy, sits in the corner while having a sad wank with his half flaccid cock, as he watches Lena getting gangbanged on the bed
again, taking the time now and then to declare how much bigger and better the cocks are than Ian's.)
Chapter 10 suggests that we'll go a certain way in that direction, but I refuse to believe that Eva's spent so much more time to establish the characters and the story if she'll take it to similar extremes again. I don't even care that much exactly how it ends up, I just like the ambivalence and tension in that path—that Ian and Lena are pulled in different directions, as individuals and as a couple.
I think the first Chapter 10 scene with Ian and Lena was close to perfect in that way ("
one of the biggest?"). It's not like Ian is dying to hear about Axel's cock while she jerks him off—it's just his insecurity and jealousy that pulls him towards it. If he's watched Lena's Stalkfap content, the idea of Lena as a sexual creature (also without Ian's presence) has established itself in his mind, even if he's conflicted about that as well. Gillian's cheating would naturally also shape his thinking around this stuff.
It's not like Lena either is dying to talk about Axel's cock when she's with Ian, but he represents the benchmark for Lena when it comes to everything sexual. So it's easier than said to keep him out of her thoughts, and when Ian unexpectedly mentions him … she grabs the chance. Even if giving Axel that kind of presence in her new relationship also is something she
really doesn't want to.
I'm hoping Eva will keep making use of that friction and ambivalence instead of settling for solutions like the "I just love talking about being fucked by other men while I deny Ian" stuff we saw the outlines of in the next scene. The former could both end in healthy or unhealthy relationships, and could involve both characters doing shitty things to the other. It just wouldn't make Lena mean or without any reflections about what she's doing; and they'd still have reasons to be together, even if some parts of the relationship ends up as dysfunctional.
