I did, and I opened my game up again rn just to confirm it a second time. The only options while she is positioned doggy style are, Reset Shirt, Reset Panties, Reset Legs, Pat Head, Finger Vagina, and Penetrate (masturbate and blowjob for the friend on the floor). I can confirm there are no mouth options and anal options while she is in the doggystle position with the t shirt up and the panties aside. My version is still REC_v0.3.2.3.1 and is the same save with all upgrades except gold brick unlocked.
Unless you can clearly explain exactly where and what icons need to pop up im fairly certain that the option is not available in my version.
There are no anal and mouth options during doggystyle with shirt up and panties aside, it is very possible im just dumb but im reconfirming it and it still isnt there.
Edit: For more clarification the only times i can use the mouth options are when she is lying on her back, missionary position
2nd Edit: Downloaded a new file from itch, put it in a different folder, created a different save, put in all the cheat codes. Still cannot do anal or oral during doggy position with tshirt up and panties aside. Its either a bug or the dev forgot to put it in.
I think i'm just stupid. I can't find the icons like 'turn over' after undressing her while she is in the missionary position. Even while she is in doggy/laying on stomach i cant find anywhere to take off her clothes except lift shirt and move aside panties. Yes it's probably stupidity on my end but i just cant find what your talking about.
