Succubus Research Diary

“Would you show me your ****?”
Those words began it all. A sweet melting affair with the widow.
Since he was young, Akito Narazaki (you) had yearned her — an older girl who had become a sensuous elegant woman, but had married young, dashing his dreams. But now Ayako Sonomura (Ms. Ayako) was a tragic widow, and not only was Akito closer to her than ever, he was moving in and making a life under her roof. Together they lived a sometimes calm, sometimes tense, sometimes heavy life…
An orthodox adventure game spanning one year of Akito and Ayako’s relationship.
Experience the tumescence of budding spring to the snowfalls of winter, share a home and a life with a tender and beautiful woman.

A Night With: Succubus is an adult romance visual novel that transports you to a medieval world filled with desire and supernatural intrigue. You play as a solitary individual living on the outskirts of a quiet village, yearning for excitement and connection. One restless night, you discover an ancient book containing a mysterious summoning ritual. Out of curiosity and boredom, you perform the ritual—never expecting it to succeed.

In a flash of otherworldly energy, Seraphina, a powerful and alluring succubus, appears before you. She's not just a creature of temptation; she seeks to absorb the lewd energy of those she deems worthy. Seraphina isn't easily impressed—she'll tease, flirt, and test your deepest desires, evaluating your every move to decide if you meet her standards.
