At first I thought this was gonna be a "romance" type game in some capacity... I swear it had the romance tag originally...
... Boy was I mistaken. /vomits-at-poor-Aiko's-fate-repeatedly
EDIT: I gotta say though... forcing Aiko to strip and go down on Jessica AT THE POOL during the day with the whole freaking family home... This, to me, seems like a stupid idea just begging to make Sarah look like a villian to her own daughters. Anyone could walk out there at any moment, and it's not like they could just pretend nothing was happening...
This just screams of shotty storytelling just to get a moment of more rape in the game....
