Altdegen

Two girls find themselves flung into a world of magic, atop an altar covered with fuzzy blankets and pillows. The second they see one another, feelings begin to build within them. Their hearts begin to pump, and a connection seems to form.
Before they know it, they lose themselves to their lust, unable to control themselves as they fulfill each other’s desires perfectly.

In case this description wasn’t obvious, the love interest is the MC’s twin sister. What can I say? Twincest is wincest! This story is also pure girls love. There will never be sex scenes with male characters.
MC is also a futanari, as well. If you don’t like stories with any of these elements, you’re gonna REALLY hate mine.
