Sinful Summer: A Tale of Forbidden Love [Ch.3.6] [Ruykiru]

Embark on an unforgettable journey with Erik and Lyna, two young twins entangled in a passionate web of desires. Set against the breathtaking backdrop of a private tropical island villa, their reunion after a year abroad sparks a fiery exploration of emotions that defy traditional boundaries.

As they tread the line between repressed feelings and mutual attraction, their bond deepens and the craving for the forbidden becomes impossible to ignore. With the arrival of their mother Helga on the horizon, will they succumb to temptation or resist the call of their primal urges? Discover the twists and turns of this compelling narrative through a kinetic visual novel where love, family, and desire intertwine in very interesting ways…

This visual novel has a heavy focus on the incest taboo itself and making the family relationships actually matter and mean something more than just a label. A lot of attention is paid to sound effects, music, descriptive narration and unique angles to enhance both the story and the sex scenes.
