1)Group sex as random event - when the heat of the 3 character's at max
Also you could make it, like inviting 2 character's for group sex.
2) map expansion (and this meansmore character's:)
that actually a really good idea, and i what to suggest something kinda awkward.... maybe fart fetish actions? you know like fart on face,penis,nose and anything else i really would like that type of thing on game and maybe new island like to entire world,expansion of the machine to get more girls and maybe new mechanics
