I just don't see a satisfying way for that to be implemented given what I know of the RLE framework.
First Step - see a girl, she's doing something. You didn't consent to that now, did you? You have your own needs.
Second Step - approach the girl, don't interrupt what she's doing. Or do since games always believe you'll only approach someone if you want their attention. So far tho', everything is according to what RLE taught us about woman-kind.
[Let us approach her without saying anything something we can only do when the stats between Null and the girl are high enough. Alternatively, set that as just a thing that happens between lovers or sex-friends - maybe let them come up with the idea or give us the prompt to bring up the idea.]
Third Step - touch the girl in any perverted spot, let her decide if it is or isn't alright as she just goes on about her business. Further in step five.
Fourth Step - no words needed, if the girl doesn't shove you across the room with her mind/drains your life force/slices you into pieces: remove her clothing.
Fifth Step - commence intercourse as normal. The context just changed and now she compliments you and moans as usual.
(I'm just being funny, don't take it as condescending. If anything, I lack the will and intelligence to try and present it in any other form but a satire - with the context that this will be a game in mind.)
