So far, this game version not yet have any scene of Max bangs Ann (Mom) / Alice (Sister) / Lisa (Sister), only few Sex scene between Max & Aunt Kira at Night, if the Mod kill Eric choose to Kill Eric, then the game will become very Boring~ there is no more Sex scene between Eric & Ann at the Livingroom / Ann's Bedroom / Bathroom.
Then maybe replace by Ann watch movie alone at Livingroom and Max ask to accompany her, Ann sleep alone every night at her Bedroom, Bathing alone every morning (as the version now NO SEX scenes between Max & Ann, so the only SEX scene have is between Max & Aunt Kira)
Imaging when the game become like this, nearly NO Sexual Content as only have Sex scene between Max & Aunt Kira, quite BORING~ If want the Mod Kill Eric, I think better wait until the version update to open the Sex scene of Max with Ann / Alice / Lisa, then if that time kill Eric, at least can continue the story between Max with Ann / Alice / Lisa to build up the Sex relationship.
