Not currently included in the newest 0.2.2 version.
Starting with v0.2.3, I'm working on adding more optional scene choices, including things like anal content, tickling, etc., so there's more variety. I can't promise every specific option will make it into the next update, but adding more variety to scenes is definitely the direction.
So, to answer directly: yes, anal content is planned, but I can't promise it will be included specifically in v0.2.3.
