A serious maid unexpectedly turns into a succubus. She straddles her master and sucks up his semen with her pussy, a succubus maid forced into depravity

I hired a gentle and unassuming girl as my maid, but her personality changed day by day, and she started observing me with lecherous eyes. Finally, she pushed me down and gave me a sudden blowjob, then gave me a hard erection and rode me in a demanding, pile-driving cowgirl position! In the end, she squeezed out my semen! Her sexual desire grew stronger and stronger, and suddenly horns sprouted from her crotch and a magic circle appeared on her chest... that's right, she had been taken over by a succubus (lust demon)!
