Maybe a pill for the MC to make his dick bigger/longer? to allow for cervix penetration, and further more, making our fuckable bot able to have "painful" interactions if you take too much of the pill(s) and then you'll have special dialogue outside of the streams while you're outside if you take a LOT of the pill(s)
side note, if you add a footjob position it'd be funny if the bot says it can't do anything for you and just sits there until you actually add the position, and maybe you can add a "cumming soon" section too
