Life Hacks/Summer's taboos and interests
Sexual history
If idle hands are the devil's playground, then Summer is a perfect and pure angel. She has heard the absolute abstainance until marriage message she has heard in school about sex mocked by her school social circle, but she knows she does not have time for a dating life so her actual opinions on the matter don't count for much.
Summer doesn't even really get enough time to masturbate. She has become slightly bi-curious, mostly due to her sexual frustrations, for her sister Winny. They have masturbated together on occasion since they share a room, but they both have a silent agreement that it means nothing sexually and doesn't count them as Lesbians.
Summer has a somewhat dark desire to get a male classmate with good prospects to knock her up while she is still in high school so that they can get married and he can take her out of this hectic life at home. However, she doesn't have time to date, so she doesn't see much chance of that ever happening.
