Prologue
"Haaang…!!"
A beautiful woman is shaking her waist on my dick.
Each time she moves her body, her sweat-drenched pink hair flutters in the air.
"Keuh, Mother…"
"Oh, son? Not Mother, but Ma.ma♥?"
The woman who said that was beautiful beyond compare to any celebrity.
Her milky skin was softer than a baby's, and her petite but distinct features and the two eyes sparkling within them were reminiscent of rubies.
Each time she shook her waist, her bountiful breasts heaved, and her waist, tightly gripped by her hands, was thinner than my thighs.
Squeak, squeak, squeak!
Yes, that person is my mother. To be precise, my stepmother.
However, being a stepmother isn't really that big of a problem.
Even though she is registered in the family register, we don't share any blood.
Rather than guilt or a sense of depravity, I am grateful that I can have sex with a woman like that.
But.
The uterine tattoo on her stomach, the tail that wriggles and tickles my nipples, and the large horns protruding from her small head were definitely a problem.
She is.
No, every living thing in this house except for me is.
"Sera! I'm cumming!"
"Oooooh...♥!...Son, with your virgin dick...I'm going...♥!"
Fwoosh!
She was a succubus.
