He must watch how monster is fucking Triss locked in stockings. Meanwhile she strokes his cock and he must watch because he loves Triss. Yennefer thinks that one cock isn't enough for this punishment, so she uses her spell to grant monster with two cocks and now he's fucking both holes of Triss from behind. Next thing we see is a wolf fucking Triss and Geralt is helping her with that. That's also some kind of spell. Next character is a big giant fucking Triss in the forest and cums inside her. Triss got pregnant and gave birth to devilish child.
