Mermaid hell - The day four mermaids were attacked by 10,000 demons

Demons have been resurrected after a thousand years of sealing. There are over 10,000 of them.
The demons head for an island where beautiful mermaids live…
There lives a mother mermaid and her three daughters.
Mermaids are prey. Prey for the demons to indulge in their desires.
Mermaids are fish from the waist down.
Humans call them mermaids.
However, mermaids have a slit between their legs, and the organs that function as genitals remain.
They are well-built, with full breasts, curvaceous waists, and big butts.
It is their beauty that attracts the demons.
The demons thoroughly devour the slits of their private parts.
It doesn’t matter if they can’t spread their legs. Even though her crotch is closed, the devil forcefully rapes the mermaid!
The mermaid’s pussy, deep inside her closed crotch, is now opened for the first time!
The devil first attacks the mother… Then he attacks the fleeing daughters one by one.
The mermaids are unable to escape in the sea, which is protected by a barrier, and are quickly cornered…
The devil beats the daughter in front of her mother, who begs for help, and then finds her crack and hard-rapes her!!
The devil continues to thrust into her, even as she cries out “Mommy! Mommy!” Gangbang and creampie! Repeated egg-laying!!
The never-ending story of a mermaid whose screams echo throughout the island.
