To be clear I meant variations in the text more than the renders, the act would be the same it's just that Riley would be going into it with a different mindset if it was her first, second or nth time fucking a guy other than her husband.That is a great idea not gonna lie but I agree with your last statement, even smalls variations would multiply the number of renders by a huge amount and i am not sure that is feasible.
But even still, while this game's updates are decently sized (especially for the pace of development) having several major scenes like these released all at once may be a bridge too far.
