Hello, i do plan on adding head pat and a few more of such actions into a special game segment (after Lust is filled, camera zooms on the girl and the player can pet the girl to lower her lust, including patting, cheek rub, fingers in mouth lick and more).
However this feature is current in concept stage, scheduled for version 2.2 or so (sorry for the extra wait).
Feel free to write more suggestions if you feel like those would feel awesome ;)
Cheers,
