Found a bug/typo in the latest build. I'm playing it using the raw files so I have the latest version. Release 57 / Serial number 140902 / Inform 7 build 6L02 (I6/v6.33 lib 6/12N)
In the comic shop with frank, after you've had sex with him a few times, it opens up an options menu when you go to have sex with him that looks like
1 - Fuck him A
2 - Fuck him B
3 - Receive oral
4 - Get fucked A
5 - Get fucked B
6 - Give oral
7 - 69
The descriptions of the actions are messed up for the Fuck options. The fuck him options are described as you being fucked and vice versa for get fucked, as well as being opposite of the description (I/E being bent over the table vs being laid out on the table)
