Dont think Proposition series just about Mrs Keagan (even she looks main there) it goes with some other comics like Home Instruction, Mrs. Hani, etc. Thats what it makes it unique then other series. Probably there will be more other comic series involve so it will be more fun to read it at future.well i don't know why dukes keeps with mrs keagan ,because in others history's when the milf get in a complete cheap whore used as sex slave by bbc the history finish , but with mrs keagan keeps going when many chapters ago she finished as a cheap whore i don't know why ???
