At the start of the game i went south from my house to the girl standing at the door infront of the old man's house, i request sex, scene shows MC on ground and the female does 2-hand hand job with old man looking out window, both of you notice old man and....HANG or lag...very long very very long very very ve- well you get what i mean.
I tried this with Mithril Sword +3, Myterious Key, Nudity Glasses(she stand naked at door but during hand job she got cloths on), Mystic Banjo...well still hang during hand job so don't think is item issue.
