Chrystal:
Two new study scenes, in addition to a rewrite of the one already in the game. Each of the scenes will play out in order so just hit the study button and you'll be taken to them.
You can now send her home to practice on a dildo. When that scene has played out be sure to send her a message via the phone to start receiving some pics. If you send her another message you'll get the chance to direct the action so that scene can go two ways.
A breast groping scene
Butt grabbing scene
And last, something I haven't done before but I thought was pretty fitting for Chrystal at that stage, a thigh fucking scene.
Every scene for Chrystal Tier 1,2 and 3 now has a small notification at the end of it saying which of her attributes changed.
Also there is probably some small changes to the scenes already present at Tier 1, but they were mostly spelling corrections and minor rewrites.
