Fuck yes that will be peak cinema,DO IT...JUST DO IT MAKE YOUR DREAMS COME TRUE JUST...DO ITTTT!, sorry everybody but my reaction was like that Shia labeuf video haha
And when mizora fucks karlach at one point she could switch between vaginal and anal and then at one point she could do the switch again and then cum inside her pussy, after that we see mizora making karlach give her a blowjob in revenge for karlach doing the same to her at the beginning of the sex scene before the anal sex, then karlach in retaliation rides mizoras cock until she cums or until she sees stars or something and by the end karlach could fuck mizoras tits until cumshot and we could finish with a final scene with mizora being Karlach new sex slave.
PD:i would like to see more ideas from the users but i dont know if this could be a deviation from the thread.i did a little edit in which I corrected some errors in the words because I was in a hurry. I hope you like the idea.
