I'd like to see this in less of a harem route. Mei calls you both perverts and Meg thinks it's great if you give your own sister an orgasm with the power. She's totally up for all the sexting and video calls. So I'd like to see her encouraging and maybe even faciltating casual threesomes so that you can gain more powers. Whilst keeping a loving relationship between the two of you and not a harem.Considering Meg knows that Emma can get permanent upgrades through sex, I would love to see Meg take a role in encouraging Emma to collect as many as possible in the harem route.
