Well this certainly is unique

Base +6

Unique only if you insist of this exact combination of attributes. Works involving people fucking pigs are a dime a dozen; want Mabel and Waddles specifically, still pretty common. Anthro pigs, also not too rare (e.g. Kingbang's "Mrs Gutter" series); want more animal smegma/nastiness, look up Sadgravy's "Cowmic". You're welcome.
