The pacing of the story (sexually) varies depending on which main characters. For the daughter's side the pacing is slow , but that's probably because she hasn't really had a relationship and a virgin still (if I remember correctly). However, it starts to 'pick up' in the later days. In my opinion, there's more playful teasing than anything (other than a few moments). Since both the mother and the MC are around the same age and they're dating, the pacing is consistent since the start of the game.
