EOK-006 - My sister is way too horny, Mai Hanano

The portrayal of the 'older sister' is quite realistic—from her blunt, non-forced tone and condescending attitude to the small detail of her referring to herself as 'onee-chan.' The first half features a series of the younger brother's fantasies, ranging from the bossy sister acting as a submissive slave to her seducing him in erotic costumes, which keeps things varied. In the second half, the 'real' segment follows a flow where the brother uses his sleeping sister's hand to masturbate, ejaculates on her face, and runs away, only for her to come and seduce him the next day. It’s fun to imagine what she was thinking during that time. The gap between her condescending 'you can do whatever you want' attitude and her full-blown masochistic reactions is a huge draw. I liked that it didn't try too hard to be overly gimmicky.
