The hero wants to have sex

You blurt out "I-I have never been with a girl". The dark elf queen smiles "Is that so? Well we can't have a noble hero like you stay a virgin! Answer me truthfully, is there a girl you like"? "Y-yes I have fallen in love with someone recently".

The dark elf queen seemingly reads your mind "Is that someone from the dark elf kingdom"? "Yes your majesty". The dark elf queen plays with her hair and says "You have saved our kingdom, hero. I'm sure the dark elf girl you have fallen in love with will be very happy to sleep with you as your reward! Come on! You can tell me who she is"!
