Succubus Yondara Gibo ga Kita!? Episode 2

Ever since the day I summoned the succubus in a ritual, Erin has been appearing everywhere even though I didn’t call her.
She appears from under her desk while studying and plays a tutor, and has sex in the pool under the blue sky.
One day, Takashi finds a hickey he made on her mother-in-law Eri.
