Wait why the rhot in me so possessive like when sparring with him also the way he speak if you do scene in bedroom at the ruins he show his possessive nature and I never had that cursed lizard encounter during that quest
Rhot actually has two encounters on the Forest Hunt, you just have to time it right. You, Rhot, and the enemy lizard have to step into the same tile together and it will trigger the extra event for Rhot.
Basically you end up seeing him beating up a lizard and you get horny and offer him a blowjob in the woods. While blowing him, the beaten up lizard wakes up and gets hard seeing what's happening. Rhot then pushes you back slowly until your ass ends up on the enemy lizard's cock... and well you can imagine the rest.
