Seduction Level (SL) is a mechanic in Total Seduction that enables you to have sex scenes with any character you are able to seduce. Successfully seducing a character depends on your current power; if you do not have enough, you cannot seduce that character at that time. Each time you seduce a character your seduction level with that person increases by one, and it can be increased to a maximum of four. While most scenes require a seduction level, some do not.
SL1 - You can ask for oral sex
SL2 - You can put it in her pussy
SL3 - She will not refuse anal
SL4 - She will join group sex and be able to be possessed
