I feel that if you're going to do that, then the gifts should be something specific for each girl, rather than a mystery box. Clothing is already covered, as are sex toys, so maybe something more specific and personal? Maybe personalized jewelry, or a coupon for a spa day, or some other similar idea?
I know some will hate this idea, but I wouldn't mind seeing more lesbian activity, particularly kissing.
I'm guessing Autumn will have some exhibitionist training soon. Given where she's coming from, I'd like to see that move very slowly at first, like wearing more revealing clothing in public, maybe clothes shopping with the MC watching her in the changing room, slowly escalating to her being naked on the beach having sex with the MC.
Also, more Hana please.
