this is a goblin from one of the guro projects i was working on a while ago but it got scrapped because my art style changed a bit and don't really want to redraw everything but didn't want the gif to go unseen for this gob.

The story was this goblin works at a massage parlor and manages to pull in a customer who's part giant due to a contest between her and the other adult workers at the establishment.
However, the person she pulled ended up being too big downstairs for her to do anything with, so oral and sex was out of the question and since the store had a policy of no refunds, he didn't want to leave without getting his money's worth.
The gob offered to allow him to watch her masturbate but he wasn't having it and decided to force himself on her and rape her, she screamed but it didn't matter since the room had a noise canceling magic barrier placed on it.
So, he continued to rape her until she frothed from the mouth and lost consciousness from being chocked during an orgasm and even then he didn't stop, until he was tired, and her belly was swollen with his seed.
Worried that she might be dead the man informs the mama-san who tells him the old saying "you break it you buy it". she wasn't dead the mama-san confirmed but since the gob was a sex slave and the half giant man destroyed her holes to the point where she could no longer be used by normal sized customers his only option was to buy her.
