It isn't one of those AVNs really. Kajia will fuck MC at the start because you had an ongoing relationship, Finn fucks MC when she does because it's the last chance, Kate, and Kari and the subway girl will all fuck MC after a night of drinking - but as for the main Lis - I'm not sure but I don't think that there has been a second tumble with Kajia, MC and Fionna had their first kiss right before MC left to see the Alfir, you haven't gotten so much as a pat on the back or a handshake from Medb yet - so there has been just enough sex to keep people from getting mad at Ceo and trying to slap a "No sexual content" tag on it, but - aside from Kajia right out of the gate, MC hasn't gotten very far with any of the Lis.
