I like the build up a lot.
I noticed some ppl complain about, but personally i think its great.
There is one thing I would change. Over the course of time and increase to love statistics, the girls should start to allow to do all the lewd stuff without the rubber.
Another thing is expansion to the scenes already there, so for example a scene that end with handjob could end with a swallow. a cum on hand to cum on body/face ect, ect.
I would not mind the build up to go on for a while with just advancement to the scenes already in placed.
