Not a sex pose, but close... In my opinion this game really needs this 2 things very much:
1. Kneeling pose. Without masturbation or any other activity. Just obediently staying on the knees.
2. Crawling animation. Like we have run/walk - so would be nice to have run/walk/crawl.
It is not some hardcore thing, it will not offend anyone, but it's really important to have this in the game for some bdms-related RP.
