Those are in upcoming versions probably around 0.7. I've got the pictures done but not got to the part where they would be appropriate to code them in yet. 0.4. should have the beginning of Grandma doing stuff (kissing) with Baguette and from there it will escalate in future versions.
Yeah show a lot of that, and I mean a lot of it.
Also would like to see Grandma's friends in the game and detailed stories of her past and also daughterr's
All this is new for the newly formed couple and they seem interested in being part of it at a slow pace.
The NTR part or bad guys don't seem to be much of a threat, maybe they could be to make the game a litte more interesting.
Every game needs a bad guy or would be self proclaimed boyfriend that wants to steal the girlfriend away.
Unless it's a girl or they found another Futa that wants the girfriend for herself, that would be acceptable too or wants to join.
Let's not forget Grandma has siblings, they could be payed a visit too and make the story longer by all means.
