Desperate to lose my virginity, I summoned a succubus with the hope that even straw might save me. Then, at the moment of her appearance, my older sister opened the door to my room! In the magic circle was... a succubus possessing my sister's body! I fainted, and when I woke up... the magic circle and my sister were gone... a dream? However, gradually, the incubus that had gained control over my sister's body began incestuous acts without restraint, relentlessly impregnating and milking me. What if my sister gets pregnant with my child... sweat.
