Overview:

Succubus Sister is an erotic hula style simulation where you provide semen to your sister.
I like the spunky younger sister who remains cheeky until the end.

My sister has developed a disease where she can’t live without drinking semen…
Let’s ejaculate a lot for my cheeky but cute sister.
There is a story mode that includes short episodes, and an after mode that specializes in excerpts.
There are 3 scenes: tongue cumshot, blowjob, and insertion.
