Lillian Night Succubus Exclusive Contract (リリアン☆ナイト サキュバスの専属契約)

One night, when I was about to start my usual event before going to bed,
a girl suddenly appeared in front of me.
She’s… she’s flying, has wings and horns, and doesn’t seem to be human.
She swallowed my semen in the name of tasting it, and asks me
\”Would you like to sign a contract with me?\”
What will you do…?
